. . . It's that one day a year I get to post pictures like this, Happy Valentine's Day! Well, perhaps Halloween as well . . .
With apologies to Jackie DeShannon! What did you expect from someone who taught Cardiovascular Anatomy and Physiology?
Have a great Friday and weekend Facebook, Flickr, and 500px friends!
I put it on manual and experimented with backlighting a little. Not great, but better than I expected given the lighting situation. I have books going on my iPhone (audiobook of "I Shall Wear Midnight"), paperback ("Bad Feminist"), hardcover "Why We Broke Up"), my iPad ("The Scorpio Races"), and I had time to kill today so I went to the library. And ended up with two more books ("Lizzy & Jane," I couldn't resist the book title...hopefully the books is good and "Notorius RBG".... it's on my Read Harder Challenge list), because why not....it's almost the weekend, right? Maybe I won't even get out of bed.
Put Endor up one last time to hopefully get some pics for a magazine. The wife couldn't wait for me to take it down as it was in my living room for 2 weeks.
Put another 'x' on the calendar
Summer's on it's deathbed
There is simply nothing worse than knowing how it ends
And I meant everything I said that night
I will come back to life
But only for you
Only for you~♥
Just another shot of Temp from my trip to the beach :)
School starts for me on September first, and I would normally be pretty excited, if I wasn't going to end up in the same Psychology class as my older sister T___T
McGills have put 26 new Alexander Dennis Enviro 200MMCs into service. 11 shorter Enviros on service 26 between Glasgow-Braehead-Paisley-Nethercraigs and 15 longer Enviros on service 23/X23 between Glasgow-Braehead-Erskine.
Seen in Braehead is new 4107 - YX19OSV.
I put in a roll of Portra 800 and then wrongly assumed it had been Ektar 100, so I overexposed every shot by 3 stops. It didn't matter much, apparently. The highlights are a blown out, but otherwise the dark parts would have drowned in black.
I have created a Flickr group for photos shot with and of this rare camera: --> Click

put a pile of Kosher salt under the microscope and with a bit of focus stacking and Photoshop got a cool image. The Kosher salt is a lot more interesting than the regular salt.
Our aloe plants have put our flowers following the recent rains, and I brought these inside to photograph where it's easier and more convenient to light.
Lighting stuff: Lit with a Yongnuo strobe in an 8.6 inch Lastolite soft box at camera right. Fill light is from a small mirror at camera left. The flash and my tripod mounted flash were triggered with a Yongnuo RF-603N.
Other succulent and cactus pictures that I've taken can be seen in my creatively titled Cactus and Succulents album.

I've photographed a lot of plants and flowers, because they're all around us, work cheap, and never complain. I have an album of these images with over 1200 pictures, and for each one, I have described how I lit them, in case you're interested in that kind of thing.
I thought id put up a variation on one of the previous shots from this location.
Shot in the Ahuriri valley one very cold frosty morning - after two hours out I had white arms from frost, and the distance meter on the lens had completely iced over!
Comments and critique welcome.
Put the "romance" in romance novels with the new Lusty Library, available NOW at Equal10 for the August round! As always, check out the demo at our brand new mainstore or pick it up at the event. And don't worry, all of these stories come with happy endings. 📖
Earlier, I put up a photo of a chapel in old San Juan covered in pigeons and mentioned that it was right by Parque de las Palomas, or Pigeon Park. Here's an example of how mnay pigeons were there. Kind of reminded me of a mini Saint Mark's Square in Venice.
It actually wasn't too crazy until a group of school kids showed up. After laughing at the "gringos with their cameras", they began throwing food on the ground to attract all the birds in the area. Once there was a sufficiently large group, they began chasing the birds, causing mass panic and chaos. I almost got nailed by several pigeons rocketing out of there. Several of the kids managed to actually catch the terrified pigeons and would carry them around proudly. After a few times, they began offering to do it again for the photographers for money. I declined, but if I hadn't gotten about a hundred shots before then, I might have taken them up on their offer. :)
Put on a plaster and it is al forgotten about. Too many exciting things going on a round to be sad for too long. If he saw my camera pointing in his direction, he would stop what he was doing, pose and a smile filled his wee face, like the sun bursting through the clouds on a dreary day. He was a joy to hang out with and kept bringing me packets of crisps and sticks and boy-stuff found on the ground to share with me. The hour I was in his garden with him and his family, fair made my day! :-)))))
Rules: Put your first ever made doll photo with your last one, and add the year of each one.
Even though I was collecting way before 2013, I only really started doing it seriously then...and as you can see, I started collecting the dolls I wanted but just missed out on as a kid;- the early/mid 70's gals, Sweet 16, Free-moving and Quick Curl Deluxe- The QC and her outfit were both NRFB and I got both for a song (how times have changed! ...The booklet at their feet was mine from childhood, and was the item that first ignited my wanting those dolls! Unfortunately, it was an old booklet that was packed with my 1st issue Pretty Changes, so those dolls weren't available anymore.) Ever since then, I seem to be going back in time... and the settings have gotten a bit more elaborate than just my PC desk.

Beavertail Waves at Sunset
It seems like forever since I have spent anytime on my photography, but tonight I sat down, put on a little George Strait and searched for a photo. I came across this show of the waves breaking on the waves at Beavertail on a recent summer evening.
The heatwave being still virulent so far, suffocating us with 35 to 37° and not under 25° at night, I'm staying indoors... though the temps are above 28° in the house...
I walk through the house, looking for a corner to photograph waiting for cooler temps outside...
I cut a branch of hydrangea from the garden, put it in an old bottle and placed it on the mantelpiece of the living room.

Puppet on a String
Now, if we both agree, our newly minted Mrs.D…., Parden me! Lady D. Calabash,
Agree that pistols are just rude and unnecessary …… I will just put this away this objectionable bit of melodrama, and we can continue on with My requests like reasonable adults..
Now, just nod yes with your pretty tiaraed head……
Capital ! Now might I suggest that you keep that frog in your throat from escaping, and stay mute for a bit…There, that’s the girl….
Obviously, you Milady, received our missive, and was just curious enough to come alone see what it was all on about.
But first, please allow me to force upon you apologies for intruding like this upon you day of Matrimony… but now that you are securely wed, these matters needed to be discussed with the upmost urgency…
Ahhh…I saw you glancing away towards the door, but don’t worry about holding up your wedding party Milady… interesting use of a rather rude appellation that, hold-up I mean….., for you see, your entourage is currently being, let us say, “ entertained” by my fellow friends in a manner that your absence from them will not be dwelt upon for the time being….
Ah, did I just see a shiver along your pretty physique? But as a thief yourself, you should not be aghast by my words…
Now… don’t look at me like that, We really do know your little secret….! And No!, allow me to make our position quite clear Lady C… we are not blackmailers, just simple jewel thieves.. not unlike yourself…
Ah I can see by the look in your eyes that you know we are of the same mold, so it is of no use shaking your shimmering head like that, your crafty game is up, now is it not?,
But I must say that your diamond earrings and tiara really put on a jolly nice show whilst you were nodding no!
But let us put those pretty distractions aside for now, and I will make it quick and to the point…. As I know you would prefer it to be…
You’d admit.. That you are a dirt poor lass by heritage… having only been posing as a one of wealthy elite to snag your disgustingly wealthy Intendeds affections, and that all of the jewels you have been flaunting in his and the Lord’s family’s face actually were “shall we say…borrowed” from the rather obscenely rich, family less spinsterish old lady, whose bed-ridden condition you became nurse too , after of course, you were able to convince her to discharge the au pair she was at the current time employing!
Hush, I see you want to argue the point, but that photograph you are holding,, one of several I might add, tells you that the proof is in the pudding against any defense you might try to stage!
My dear just accept the fact you have been found out, and listen quietly without further attempts at interruption and I promise it will be less painful to you all around….
Actually I am doing you a favor my pretty miss… We have already made it appear that your charges safe has been burgled while she slept , and have taken the liberty to remove the rest of her jewels you had secreted away in your chambre , really, under a mattress? Which means that all blame will fall squarely upon my lot for their sad loss.
Don’t gasp like that My pretty Lady, you knew the charade would have to end, and we are presenting to you a way to gracefully exit without being found out…Consider it our wedding gift to you….!
Now attend please, as I have stated, we are not blackmailers, we want nothing more from you after this day than information. Oh come now miss, don’t look coy, you know full well the type of information we can use… Dates of balls, dances and the house guests who will be staying with you at the Manor will suffice…. and no tipping us off to anyone, we will have eyes upon you, the same unseen eyes that have been following you for quite some time now….
Quite fetching, the way you placed your hand to your open mouth just now, That ring really does sparkle a bit, showy little gem!
So…You really had no Idea someone was on to you?
Allow me to reiterate our position then…for one year of your cooperation, the picts and negatives are yours, and we will vanish totally out of your life and let you live happily ever after with your prince, er Lord!
Ahh, I can see it now in your pretty eyes, Game set and match in my court. But do not stress all too much over it, the unpleasantness of being our snitch should last only for a year from today, providing of course we are satisfactorily compensated by your disclosures….
For trust us, for even the dimmest of police inspectors will notice a pattern eventually, and we would prefer to leave you with no ideas of spilling your story to anyone by milking information from you to the point of desperation….
Now me fine lass, Since you are rather talented at telling stories, I harbor no doubts that you will be able to put on a good show for the next year…… also when when you soon rejoin your party today. Though actually I may suggest you remain here and have them find you huddled in a corner at the shock of your loss..
What Loss your eyes appear to be asking?
Well Lady C… It will be best if it appears that you have met the same unfortunate fate as your bridal party… Now don’t balk at this point now Me fine Lady… We have come much too far along this path too to dicker over minor facets of your indiscretions !…
As the preacher said a short while ago , do you take this lady for richer or poorer, and through your husband ‘s exuberance in agreeing to it, than you should not have any qualms about handing over to me the jewels you are wearing….
Now be a dear and do it quickly, it will be painless… then just begin a new , honest , life with your Lord…for I can tell you, after crashing his bachelors party, that the clueless whelp is actually quite a bit in love with you….
Balking a bit Luv. ? … Here allow me to direct….
Start with the necklace Lady D., good, now the rest..
There that’s the ticket…. you’ve got the idea now, quick and easy, that’s a good lass.
No Now, keep the wedding ring, but slip off the other My dear Lady C.!
Is that all of it, not holding out our we? Capital!
Thank you now, quite a lot actually, And see that did not hurt so much did it?
Look! Quite a lovely handful they do make, just admire their shimmer and shine. Well, I will put these twice stolen baubles away for now, not further taunting, quite rude of me I will admit!
And now, allow me take my leave of you.
^^^^^^^^^^^^^^^^
As he turned away, Lady D. Calabash felt as if she could no longer let the cat hold her tongue…
^^^^^^^^^^^^^^^^
“Tallie” she blurted out , her anxiety forcing her to say something, anything….
He stopped in his tracks, turned around quizzically, cocking his head in a questioning manner, but said nothing.
“Tallie” she said again without reason , lips now trembling, her whole demeanor shaking.
“The name of the au pair girl was Tallie”
But Lady C.’s words drifted off and died away as he smartly turned heel and walked off , but not before hunching his grey eyes up at her in a rather dismissive fashion at the wretched newly titled lass…..
^^^^^^^^^^^^^^^^
He left her standing there, dazed and confused…
Slipping down a set of stairs leading to a cellar he made his way through a maze of various objects before he reached a small wooden door. Opening it, he found himself in a seldom used back alleyway.
He stole away down the cobblestone path of the darkened alley, making his way by foot back to his gang’s hideout. Said gang, he figured, should be just now finishing up with trimming a bit of the fat from the wealthy guests.
Cause and effect he marveled wryly as he allowed various thoughts to roll about in his head while he strolled calmly away, making his escape…
Amazing the chain of events that had been set off by the simple discharging of a, seemingly insignificant, au pair girl!
^^^^^^^^^^^^^^^

To see what the significance of the name Tallie may add to this narrative….

“An Odyssey Less Taken “@
I'm used to a strange allotment of worth in my life. My truck barely worth the gas I put in it always has crazy expensive bikes and kites and skiing gear in it. But my work desk is normally pretty standard. I've got a few shiny Apple products for work and play, but recently I added a new desk ornament, which again throws off the value perceptions.
This is the result of many many many a long and stressful night spent on my Senior Design project at the University of Colorado. Basically, it is a just crazy fancy camera. I was tasked with building it up from scratch, starting with the sensor. That baby is a $5000, 5 Megapixel sCMOS sensor. It costs so much because it is more sensitive than any sensor in our pretty DSLRs, and reads out about 10x cleaner images. Oh, also it happens to read out at 100 FRAMES/SECOND, at full 16 bit resolution (higher than our fancy cameras too. The thing spits out gigabytes/second of data! This was my first time designing any electronic systems, so was pretty stoked when it finally worked.
Now, I have a few of these boards and 3 or 4 sensors sitting in boxes in my garage. At one point they were rediculously expensive pieces of cutting edge technology, now they're just pretty pieces of silicon. Makes for a cool desk decoration though! Perfect mix of nerdiness and photography for me, always keeps me motivated when it catches my eye.
Here's our little engineering site/blog in case anyone is interested.

De afgelopen weken hobbelt er allerlei materieel van verschillende maatschappijen door Putten. Vaak types die hier zelden te zien zijn. Leuke afwisseling dus.
Vanmiddag had ik net de ICNG FLOW gefotografeerd toen er nog iets vreeds opdoemde in de verte. Het bleek een piepklein treintje te zijn met maar zes assen en een lengte van nog geen 41 meter. Dit was een Stadler GTW 2/6 die normaal op de Vechtdallijnen worden ingezet door Arriva.
Jammer dat ik niet eerder door had dat het zo'n korte trein zou zijn, want dan had ik een andere lens gebruikt en onder een andere hoek geschoten.

The magnetic motor will be cheaper than a standard motor to make, as the rotor and stator assemblies can be set into plastic housings, due to the fact that the system creates very little heat. Further, with the motor's energy efficiency, it will be well suited for any application where a motor has limited energy to drive it. While development is still focused on replacing existing devices, Minato says that his motor has sufficient torque to power a vehicle. With the help of magnetic propulsion, it is feasible to attach a generator to the motor and produce more electric power than was put into the device. Minato says that average efficiency on his motors is about 330 percent.
Mention of Over Unity devices in many scientific circles will draw icy skepticism. But if you can accept the idea that Minato's device is able to create motion and torque through its unique, sustainable permanent magnet propulsion system, then it makes sense that he is able to get more out of the unit than he puts in in terms of elctrical power. Indeed, if the device can produce a surplus of power for longer periods, every household in the land will want one.
"I am not in this for the money," Minato says. "I have done well in my musical career, but I want to make a contribution to society -- helping the backstreet manufacturers here in Japan and elsewhere. I want to reverse the trends caused by major multinationals. There is a place for corporations. But as the oil industry has taught us, energy is one area where a breakthrough invention like this cannot be trusted to large companies."
Minato was once close to making a deal with Enron. But today, he is firmly on a mission to support the small and the independent -- and to go worldwide with them and his amazing machine. "Our plan is to rally smaller companies and pool their talent, and to one day produce the technology across a wide range of fields."
When we first got the call from an excited colleague that he'd just seen the most amazing invention -- a magnetic motor that consumed almost no electricity -- we were so skeptical that we declined an invitation to go see it. If the technology was so good, we thought, how come they didn't have any customers yet?
We forgot about the invitation and the company until several months later, when our friend called again. "OK," he said. "They've just sold 40,000 units to a major convenience store chain. Now will you see it?" In Japan, no one pays for 40,000 convenience store cooling fans without being reasonably sure that they are going to work.
The Maestro ~
The streets of east Shinjuku are littered with the tailings of the many small factories and workshops still located there -- hardly one's image of the headquarters of a world-class technology company. But this is where we are first greeted outside Kohei Minato's workshop by Nobue Minato, the wife of the inventor and co-director of the family firm. The workshop itself is like a Hollywood set of an inventor's garage. Electrical machines, wires, measuring instruments and batteries are strewn everywhere. Along the diagram-covered walls are drill presses, racks of spare coils, Perspex plating and other paraphernalia. And seated in the back, head bowed in thought, is the 58-year-old techno maestro himself. Minato is no newcomer to the limelight. In fact, he has been an entertainer for most of his life, making music and producing his daughter's singing career in the US. He posseses an oversized presence, with a booming voice and a long ponytail. In short, you can easily imagine him onstage or in a convertible cruising down the coast of California -- not hunched over a mass of wires and coils in Tokyo's cramped backstreets. Joining us are a middle-aged banker and his entourage from Osaka and accounting and finance consultant Yukio Funai. The banker is doing a quick review for an investment, while the rest of us just want to see if Minato's magnetic motors really work. A prototype car air conditioner cooler sitting on a bench looks like it would fit into a Toyota Corolla and quickly catches our attention. Seeing is Believing ~
Nobue then takes us through the functions and operations of each of the machines, starting off with a simple explanation of the laws of magnetism and repulsion. She demonstrates the "Minato Wheel" by kicking a magnet-lined rotor into action with a magnetic wand. Looking carefully at the rotor, we see that it has over 16 magnets embedded on a slant -- apparently to make Minato's machines work, the positioning and angle of the magnets is critical. After she kicks the wheel into life, it keeps spinning, proving at least that the design doesn't suffer from magnetic lockup. She then moves us to the next device, a weighty machine connected to a tiny battery. Apparently the load on the machine is a 35kg rotor, which could easily be used in a washing machine. After she flicks the switch, the huge rotor spins at over 1,500 rpms effortlessly and silently. Meters show the power in and power out. Suddenly, a power source of 16 watt or so is driving a device that should be drawing at least 200 to 300 watts. Nobue explains to us that this and all the other devices only use electrical power for the two electromagnetic stators at either side of each rotor, which are used to kick the rotor past its lockup point then on to the next arc of magnets. Apparently the angle and spacing of the magnets is such that once the rotor is moving, repulsion between the stators and the rotor poles keeps the rotor moving smoothly in a counterclockwise direction. Either way, it's impressive. Next we move to a unit with its motor connected to a generator. What we see is striking. The meters showed an input to the stator electromagnets of approximately 1.8 volts and 150mA input, and from the generator, 9.144 volts and 192mA output. 1.8 x 0.15 x 2 = 540mW input and 9.144 x 0.192 = 1.755W out. But according to the laws of physics, you can't get more out of a device than you put into it. We mention this to Kohei Minato while looking under the workbench to make sure there aren't any hidden wires. Minato assures us that he hasn't transcended the laws of physics. The force supplying the unexplained extra power out is generated by the magnetic strength of the permanent magnets embedded in the rotor. "I'm simply harnessing one of the four fundamental forces of nature," he says. Although we learned in school that magnets were always bipolar and so magnetically induced motion would always end in a locked state of equilibrium, Minato explains that he has fine-tuned the positioning of the magnets and the timing of pulses to the stators to the point where the repulsion between the rotor and the stator (the fixed outer magnetic ring) is transitory. This creates further motion -- rather than a lockup. (See the sidebar on page 41 for a full explanation). Real Products ~ Nobue Minato leads us to the two devices that might convince a potential investor that this is all for real. First, she shows us the cooling fan prototype that is being manufactured for a convenience store chain's 14,000 outlets (3 fans per outlet). The unit looks almost identical to a Mitsubishi-manufactured fan unit next to it, which is the unit currently in wide use. In a test, the airflow from both units is about the same. The other unit is the car air conditioning prototype that caught our eye as we came in. It's a prototype for Nippon Denso, Japan's largest manufacturer of car air conditioners. The unit is remarkably compact and has the same contours and size as a conventional unit. Minato's manufacturing skills are clearly improving.
The Banker and his Investment ~
Minato has good reason to complain about Japan's social and cultural uniformity. For years, people thought of him as an oddball for playing the piano for a living, and bankers and investors have avoided him because of his habit of claiming that he'd discovered a breakthrough technology all by himself -- without any formal training. However, the Osaka banker stands up after the lecture and announces that before he goes, he will commit \100 million to the investment pool. Minato turns to us and smiles. We brought him good luck, and this was his third investor in as many weeks to confirm an interest. Bringing the Tech to the Table ~ With the audience gone, we ask Minato what he plans to do to commercialize the technology. His game plan is simple and clear, he says. He wants to retain control, and he wants to commercialize the technology in Japan first -- where he feels he can ensure that things get done right. Why doesn't he go directly to the US or China? His experiences in both countries, he suggests, have been less than successful. "The first stage is critical in terms of creating good products and refining the technology. I don't want to be busy with legal challenges and IP theft while doing that." Still, the export and licensing of the technology are on his agenda, and Minato is talking to a variety of potential partners in other countries. Whereas another inventor might be tempted to outsource everything to a larger corporation, part of what drives Minato is his vision of social justice and responsibility. The 40,000 motors for the convenience store chain are being produced by a group of small manufacturers in Ohta-ku and Bunkyo-ku, in the inner north of Tokyo -- which is becoming a regional rust belt. Minato is seized with the vision of reinvigorating these small workshops that until the 80s were the bedrock of Japan's manufacturing and economic miracle. Their level of expertise will ensure that the quality of the motors will be as good as those from any major company. International Prep " Despite his plan to do things domestically first, Minato is well prepared for the international markets. He is armed with both six years of living and doing business in Los Angeles in the early 90s -- and with patent protection for over 48 countries. His is hardly a provincial perspective. His US experience came after playing the piano for a living for 15 years. He began tinkering with his invention in the mid-70s. The idea for his magnetic motor design came from a burst of inspiration while playing the piano. But Minato decided to drop everything in 1990 to help his daughter Hiroko, who at the age of 20 decided that she wanted to be a rhythm and blues star in the US. Minato is a strong believer in family: If Hiroko was going to find fame and fortune in the US, Dad had better be there to help manage her. He suceeded in helping Hiroko to achieve a UK dance chart number one hit in 1995. In 1996 Minato returned to Japan and his magnetic motor project. The following year he displayed his prototypes to national power companies, government officials and others at a five-day conference in Mexico City. Interest was palpable, and Minato realized that his invention might meet a global need for energy-saving devices.
Subsequent previews and speeches in Korea and Singapore further consolidated his commitment to bringing the invention to fruition, and he was able to bring in several early-stage investors.
During the late 90s, Minato continued to refine his prototypes. He also stayed in constant contact with his lawyer, registering patents in major countries around the world. Through his experiences in the US he realized that legal protection was critical, even if it meant delaying release of the technology by a couple of years. Ironically, by the time he'd won patents in 47 countries, the Japanese patent office turned him down on the grounds that "[the invention] couldn' t possibly work" and that somehow he was fabricating the claims. But a few months later they were forced to recant their decision after the US patent office recognized his invention and gave him the first of two patents. As Minato notes: "How typical of Japan's small-minded bureaucrats that they needed the leadership of the US to accept that my invention was genuine." By 2001, the Minatos had refined their motors and met enough potential investors to enter into a major international relationship, initially with a Saudi company, to be followed thereafter by companies in the US and elsewhere. However, fate dealt the investors and Minato's business a serious blow when the World Trade Center was attacked in New York. The Saudis retreated, and Minato's plans fell back to square one. Now Minato is once again ready to move. With the first order in the works and more orders pending successful prototypes, he has decided that investors don't have to be primary partners. He is actively accepting inquiries from corporate investors who can bring strategic advantages and corporate credibility with them. His company, Japan Magnetic Fan, will make a series of investment tie-up announcements in the first and second quarters of 2004. Implications ~ Minato's motors consume just 20 percent or less of the power of conventional motors with the same torque and horse power. They run cool to the touch and produce almost no acoustic or electrical noise. They are significantly safer and cheaper (in terms of power consumed), and they are sounder environmentally. The implications are enormous. In the US alone, almost 55 percent of the nation's electricity is consumed by electric motors. While most factory operators buy the cheapest motors possible, they are steadily being educated by bodies like NEMA (National Electrical Manufacturers Association) that the costs of running a motor over a typical 20-year lifespan comprise a purchase price of just 3 percent of the total, and electricity costs of 97 percent. It is not unusual for a $2,000 motor to consume $80,000 of electricity (at a price of .06 cents per kilowatt hour). Since 1992, when efficiency legislation was put into place at the US federal level, motor efficiency has been a high priority -- and motors saving 20 percent or so on electrical bills are considered highly efficient. Minato is about to introduce a motor which saves 80 percent, putting it into an entirely new class: The $80,000 running cost will drop to just $16,000. This is a significant savings when multiplied by the millions of motors used throughout the USA and Japan -- and eventually, throughout the world. The Devices ; Minato's invention and its ability to use remarkably less power and run without heat or noise make it perfect for home appliances, personal computers, cellphones (a miniature generator is in the works) and other consumer products.

US Patent # 4,751,486
(Cl. 335/272)
Magnetic Rotation Apparatus
(June 14. 1998)
Kohei Minato
Abstract --- The magnetic rotation apparatus of the present invention has first and second rotors rotatably supported and juxtaposed. The first and second rotors are connected so as to be rotatable in opposite directions in a cooperating manner. A number of permanent magnets are arranged on a circumferential portion of the first rotor at regular intervals, and just as many permanent magnets are arranged on a circumferential portion of the second rotor at regular intervals. Each permanent magnet has one magnetic polarity located radially outward from the rotors, and has the other magnetic polarity located radially inward toward the rotors. The polarity of each permanent magnet, which is located radially outward from the rotors, is identical. When the first and second rotors are rotated in a cooperating manner, the phase of rotation of the permanent magnets of one rotor is slightly advanced from that of the permanent magnets of the other rotor. One of the permanent magnets of one rotor is replaced with the electromagnet. The radially outward polarity of the electromagnet can be changed by reversing the direction in which a current is supplied to the electromagnet.
TECHNICAL FIELD
The present invention relates to a magnetic rotation apparatus in which a pair of rotors are rotated by utilizing a magnetic force.
BACKGROUND ART
An electromotor is well known as a rotation apparatus utilizing a magnetic force. For example, an AC electromotor comprises a rotor having a coil, a stator surrounding the rotor, and a plurality of electromagnets, disposed on the stator, for generating a rotating magnetic field. An electric power must be constantly supplied to the electromagnets in order to generate the rotating magnetic field and keep the rotor rotating, i.e., an external energy, or electric energy, is indispensable for the rotation of the rotor. Under the circumstances, a magnetic rotation apparatus, which employs permanent magnets in lieu of electromagnets and can rotate a rotor only by a magnetic force of the permanent magnets, is highly desirable. The present application proposes a magnetic rotation apparatus which comprises a pair of rotors rotatable in opposite directions in a cooperating manner, and a plurality of permanent magnets stationarily arranged at regular intervals on the peripheral portion of each rotor. One end portion of each permanent magnet of both rotors, which has the same polarity, is located radially outward of the rotors. When the two rotors are rotated in a cooperating fashion, a permanent magnet on one rotor and a corresponding permanent magnet on the other, which form a pair, approach and move away from each other periodically. In this case, the phase of rotation of the magnet on one rotor advances a little from that of the corresponding magnet on the other rotor. When the paired permanent magnets approach each other, magnetic repulsion causes one rotor to rotate. The rotation of one rotor is transmitted to the other rotor to rotate the same. In this manner, other pairs of magnets on both rotors sequentially approach each other, and magnetic repulsion occurs incessantly. As a result, the rotors continue to rotate. In the above apparatus, in order to stop the rotation of the rotors, a brake device is required. If an ordinary brake device is mounted on the magnetic rotation apparatus, the entire structure of the apparatus becomes complex, and a driving source for the brake device must be provided separately. The present invention has been developed in consideration of the above circumstances, and its object is to provide a magnetic rotation apparatus including a brake device for suitably stopping the rotation of rotors.,DISCLOSURE OF THE INVENTION The magnetic rotation apparatus of the present invention is provided with magnetic force conversion means which is substituted for at least one pair of permanent magnets of the paired rotors. In a normal state, the magnetic force conversion means causes a magnetic repulsion, as in the other pairs of permanent magnets. When it is intended for the rotors to stop, the magnetic force conversion means causes a magnetic attraction force. Since a magnetic attraction force can be produced between the rotors at any time, the magnetic attraction force serves to stop the rotors. The brake device constituted by the magnetic force conversion means differs from an ordinary brake device which forcibly stops a pair or rotors by using a frictional force. In the brake device of this invention, by converting a magnetic repulsion force to a magnetic attraction force, the rotors can be braked in the state that the movement of the rotors is reduced. Thus, the rotors can be stopped effectively. BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 2 is a schematic plan view showing the relationship between the first and second rotors; FIG. 3 is a perspective view of a permanent magnet; FIG. 4 shows an electromagnet, a permanent magnet cooperating with the electromagnet, and a driving circuit the electromagnet; and FIG. 5 is a view for explaining how a pair of rotors rotate. BEST MODE OF CARRYING OUT THE INVENTION FIG. 1 shows a magnetic rotation apparatus embodying the present invention. The magnetic rotation apparatus has frame 1. Frame 1 is provided with a pair of rotation shafts 2 which extend vertically and in parallel to each other. Shafts 2 are located at a predetermined distance from each other. Upper and lower ends of each shaft 2 are rotationally supported on frame 1 via bearing 3. First rotor 4a is mounted on one of rotation shafts 2, second rotor 4b is mounted on the other rotation shaft 2. First and second rotors 4a and 4b are arranged on the same level. Rotors 4a and 4b have similar structures. For example, each rotor 4a (4b) comprises two ring-shaped plates 5 which are spaced apart from each other in the axial direction of the rotation shaft 2. Gears 6a and 6b made of synthetic resin are, as cooperating means, attached to lower surfaces of first and second rotors 4a and 4b. The diameters of gears 6a and 6b are identical but larger than those of rotors 4a and 4b. Gears 6a and 6b mesh with each other. First and second rotors 4a and 4b are thus rotatable in opposite directions in a cooperating manner. In FIG. 1, reference numeral 7 indicates support arms for supporting first and second rotors 4a and 4b.
For example, 16 magnets are arranged at regular intervals on a peripheral portion of first rotor 4a. These magnets are secured between two ring-shaped plates 5. In this embodiment, among the 16 magnets, one is electromagnet 9a (see FIG. 2), and the others are permanent magnets 8a. FIG. 2 shows only some of permanent magnets 8a. As shown in FIG. 3, permanent magnet 8a comprises case 10, and a plurality of rod-like ferromagnetic members 11 housed in case 10. Ferromagnetic member 11 is, for example, a ferrite magnet. Ferromagnetic members 11 of each permanent magnet 8a are arranged such that ferromagnetic members 11 have the same polarity at one end. In first rotor 4a, for example, an N-polarity end portion of each permanent magnet 8a faces radially outward, and an S-polarity end portion of magnet 8a faces radially inward. As shown in FIG. 2, when each permanent magnet 8a is located between two shafts 2, angle C formed by longitudinal axis A of magnet 8a and imaginary line B connecting two shafts 2 is, for example, set to 30.degree. C. On the other hand, electromagnet 9a is, as shown in FIG. 4, constituted by U-shaped iron core 12, and coil 13 wound around core 12. Electromagnet 9a is arranged such that both N- and S-polarity end portions face radially outward of first rotor 4a, and the above-mentioned angle C is formed, similarly to the case of permanent magnet 8a. The same number of permanent magnets (8b,9b) as the total number of all permanent magnets and electromagnet (8a,9a) of first rotor 4a are secured on a peripheral portion of second rotor 4b at regular intervals. In FIG. 2, when first and second rotors 4a and 4b are rotated in opposite directions, each permanent magnet of second rotor 4b periodically moves toward and away from the corresponding one of the magnets (8a,9a) of first rotor 4a. The permanent magnets (8b,9b) of second rotor 4b will now be described in greater detail. Permanent magnets 8b of second rotor 4b, which periodically move toward and away from permanent magnets 8a of first rotor 4a in accordance with the rotation of rotors 4a and 4b, have a structure similar to that of permanent magnets 8a of first rotor 4a. The polarity of that end portion of each permanent magnet 8b which is located radially outward from second rotor 4b, is identical with that of the end portion of each permanent magnet 8a of first rotor 4a. That is, the radially outward portion of each permanent magnet 8b has an N-polarity. Permanent magnet 9b of second rotor 4b, which periodically moves toward and away from electromagnet 9a of first rotor 4a, has a structure shown in FIG. 4. Permanent magnet 9b has a structure similar to that of permanent magnets 8a. Both polarities of electromagnet 9a face radially outward from first rotor 4a. Permanent magnet 9b has two different polarities which face radially outward from second rotor 4b and correspond to both polarities of electromagnet 9a. As shown in FIG. 2, when each permanent magnet 8b,9b is located between two rotation shafts 2, angle E formed by longitudinal axis D of the magnet (8b,9b) and imaginary line B connecting two shafts 2 is, for example, set to 56.degree. C. In addition, when rotors 4a and 4b are rotated in opposite directions, as shown by arrows, the magnets (8a,9a) of first rotor 4a move a little ahead of the corresponding permanent magnets (8b,9b) of second rotor 4b, in a region in which both magnets (8a,9a; 8b,9b) approach one another. In other words, the phase of rotation of the magnets (8a,9a) of first rotor 4a advances by a predetermined angle in relation to the permanent magnets (8b,9b) of second rotor 4b. As shown in FIG. 4, electromagnet 9a of first rotor 4a is electrically connected to drive circuit 14. Drive circuit 14 includes a power source for supplying an electric current to coil 13 of electromagnet 9a. While rotors 4a and 4b rotate, drive circuit turns on electromagnet 9a upon receiving a signal from first sensor 15 only when electromagnet 9a and permanent magnet 9b are in a first region in which they periodically approach each other. First sensor 15 is an optical sensor comprising a light-emitting element and a light-receiving element. As shown in FIG. 1, first sensor 15 is attached to a portion of frame 1 above first rotor 4a. First sensor 15 emits light in a downward direction. The light is reflected by reflection plate 16 projecting radially inward from the inner edge of first rotor 4a. First sensor 15 receives the reflected light, and feeds a signal to drive circuit 14. Thus, drive circuit 14 turns on electromagnet 9a. The circumferential length of reflection plate 16 is equal to that of the above-mentioned first region. When magnets 9a and 9b enter the first region, first sensor 15 is turned on, and when they leave the first region, first sensor 15 is turned off. When drive circuit 14 receives a signal from first sensor 15, it excites electromagnet 9a such that both polarities of electromagnet 9a correspond to those of permanent magnet 9b of second rotor 4b. Drive circuit 14 is electrically connected to switching circuit 17. When brake switch 18 is operated, switching circuit 17 reverses the direction in which an electric current is supplied to electromagnet 9a. When the current supplying direction of drive circuit 14 is reversed, drive circuit 14 excites electromagnet 9a only in a time period in which drive circuit 14 receives a signal from second sensor 19. Second sensor 19 has a structure similar to that of first sensor 15, and is attached to frame 1 so as to be located closer to the center of rotor 4a than first sensor 15. Reflection plate 20, which corresponds to the position of second sensor 19, is formed integral to an inner edge portion of reflection plate 16. As shown in FIG. 2, compared to reflection plate 16, reflection plate 20 extends in rotational direction of first rotor 4a, indicated by the arrow. The operation of the above-described magnetic rotation apparatus will now be explained with reference to FIG. 5. In FIG. 5, rotation shaft 2 of first rotor 4a is denoted by 01, and rotation shaft 2 of second rotor 4b is denoted by 02. Only the radially outward polarity, that is, N-polarity, of the magnets of rotors 4a and 4b is shown, for the sake of convenience. Although electromagnet 9a and permanent magnet 9b have both polarities located radially outward, only the N-polarity thereof is shown. When first and second rotors 4a and 4b are put in a position shown in FIG. 5, magnetic pole Nb1 of one permanent magnet of second rotor 4b is located in a line connecting shafts 01 and 02. In this case, polarity Na1 of first rotor 4a, which is paired with polarity Nb1, is a little advanced from polarity Nb1 in the rotational direction of first rotor 4a. For example, as shown in FIG. 5, magnetic pole Na1 is advanced from polarity Nb1 by an angle of X.degree.. Polarities Na1 and Nb1 exert repulsion force F1 upon each other along line L. Supposing that an angle, formed by line M, which is drawn from shaft 01 perpendicularly to line L, and the line connecting shafts 01 and 02 is represented by Y, and that the length of line K is represented by R, torques Ta1 and Tb1 caused by repulsion force F1 to rotate first and second rotors 4a and 4b can be given by: Ta1=F1.multidot.R.multidot.cos (Y-X)
Tb1=F1.multidot.R.multidot.cos Y Since cos (Y-X)>cos Y, Ta1>Tb1.
As shown in FIG. 5, since magnetic pole Na1 is advanced from magnetic pole Nb1 by angle X.degree., first rotor 4a receives a greater torque than second rotor 4b. Thus, first rotor 4a forwardly rotates in the direction of the arrow in FIG. 5. Mention is now made of paired magnets of rotors 4a and 4b in the vicinity of magnetic poles Na1 and Nb1. Magnetic poles Nan and Nan-1 of first rotor 4a are advanced ahead of magnetic pole Nal in the rotational direction. Magnetic poles Nan and Nan-1 receive a torque produced by a repulsion force acting between magnetic poles Nan and Nan-1 and corresponding magnetic poles Nbn and Nbn-1. In FIG. 5, magnetic poles Nan and Nan-1 receive a smaller torque, as they rotate farther from the location of magnetic pole Na1. It is well known that a torque of first rotor 4a, which is caused by a repulsion force acting on magnetic poles Nan and Nan-1, is decreased in inverse proportion to the square of the distance between paired magnetic poles Na and Nb.
Magnetic poles Na2 and Na3, behind magnetic pole Na1, receive a torque which tends to rotate rotor 4a in the reverse direction. This torque is considered to be counterbalanced with the torque acting on magnetic poles Nan and Nan-1. In FIG. 5, attention should be paid to the region of magnetic poles Na1 and Na2. As first rotor 4a forwardly rotates, the direction in which a torque applies to magnetic pole Na2, is changed from the reverse direction to the forward direction, before magnetic pole Na2 reaches the position of magnetic pole Na1. The torque for forwardly rotating rotor 4a is larger than that for reversely rotating rotor 4a. Therefore, first rotor 4a is easily rotated in the direction shown in FIG. 2. Second rotor 4b is considered to receive a torque in a direction reverse to the direction shown in FIG. 2, as seen from the description of first rotor 4a. It is obvious that second rotor 4b receives a maximum torque at the position of magnetic pole Nb1. As seen from the above formula, torque Tb1 applied to second rotor 4b in a direction reverse to that denoted by the arrow is smaller than torque Ta1 applied to first rotor 4a in the forward direction. The rotation of first rotor 4a is transmitted to second rotor 4b through gears 6a and 6b. By determining the relationship between the strengths of torques Ta1 and Tb1, second rotor 4b is thus rotated in a direction reverse to the rotational direction of first rotor 4a, against the torque applied to second rotor in the direction. As a result, first and second rotors 4a and 4b are kept rotating, since a torque for rotating rotors 4a and 4b in a cooperating manner is produced each time magnetic poles Na of first rotor 4a pass across the line connecting shafts 01 and 02. In a diagram shown in the right part of FIG. 5, a solid line indicates a torque applied to first rotor 4a, and a broken line indicates a torque applied to second rotor 4b. The ordinate indicates a distance between each magnetic pole and the line connecting shafts 01 and 02 of rotors 4a and 4b. The first region in which electromagnet 9a of first rotor 4a is turned on is set in a range of Z during which a torque is applied to first rotor 4a in the forward direction. In order to stop the cooperative rotation of rotors 4a and 4b, brake switch is turned on to operate switching circuit 17. Thus, the direction in which drive circuit 14 supplies a current to electromagnet 9a is reversed. The polarities of electromagnet 9a are reversed. The torque applied to electromagnet 9a in the forward direction is stopped. When electromagnet 9a approaches permanent magnet 9b, a magnetic attract:on force is produced. As a result, the rotation of rotors 4a and 4b is effectively slowed down and stopped. Since the second region, in which electromagnet 9a is excited, is larger than the first region, a large braking force can be obtained from a magnetic attraction force. In the above embodiment, since electromagnet 9a is excited only in a specific region, a large electric power is not required. In addition, since electromagnet 9a rotates and brakes rotors 4a and 4b, a braking mechanism for a magnetic rotation apparatus can be obtained without having to make the entire structure of the apparatus complex. The present invention is not restricted to the above embodiment. With the exception of the paired electromagnet and permanent magnet, all permanent magnets of the rotors are arranged such that their end portions of the same polarity face radially outward from the rotors. However, it is possible that the polarities of the radially outward end portions of the permanent magnets are alternately changed. Namely, it should suffice if the polarities of the radially outward end portions of the first rotor are identical to those of the corresponding radially outward end portions of the second rotor. The magnets may have different magnetic forces. Furthermore, an electric power for exciting the electromagnet can be derived from the rotation of the rotors or from the revolving magnetic field of the permanent magnet.
Angles C and E are not restricted to 30.degree. and 56.degree.. They may be freely determined in consideration of the strength of the magnetic force of the permanent magnet, a minimum distance between adjacent magnets, angle x, and the like. The number of magnets of the rotor is also freely chosen.
Industrial Applicability ~ As described above, the magnetic rotation apparatus of the present invention can be used as a driving source in place of an electric motor, and as an electric generator. US Patent # 5,594,289 (Cl. 310/152) Magnetic Rotating Apparatus (January 14, 1997) Kohei Minato Abstract --- On a rotor which is fixed to a rotatable rotating shaft, a plurality of permanent magnets are disposed along the direction of rotation such that the same magnetic pole type thereof face outward. In the same way, balancers are disposed on the rotor for balancing the rotation of this rotor.

Claims --- [ Claims not included here ] Description BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic rotating apparatus, and more particularly, to a magnetic rotating apparatus which utilizes repulsive forces produced between a permanent magnet and an electromagnet.
2. Description of the Prior Art In a conventional electric motor, an armature as a rotor consists of turns of wires, and electric field as a stator consists of a permanent magnet. In such the conventional electric motor, however, current must be usually supplied to windings of the armature which is rotated. When the current is supplied, heat is generated, which gives rise to the problem that not much driving force is efficiently generated. This, in turn, gives wise to the problem that the magnetic forces cannot be efficiently obtained from the permanent magnet. In addition, in the conventional electric motor, since the armature is so constructed as consisting of the windings, the moment of inertia cannot be made very high, so that enough torque cannot be obtained. To overcome the above-described problems of such the conventional electric motor, the inventor proposed, in Japanese Patent Publication No. 61868/1993 (U.S. Pat. No. 4,751,486) a magnetic rotating apparatus in which a plurality of the permanent magnets are disposed along the two rotors, respectively, at a predetermined angle, and in which an electromagnet is disposed at one of the rotors. In a generally constructed conventional electric motor, there is a limit as to how much the efficiency of energy conversion can be increased. In addition, the torque of the electric motor cannot be made high enough. For the above reasons, hitherto, various improvements have been made on existing electric motors, without any success in producing an electric motor so constructed has providing satisfactory characteristics. In the magnetic rotating apparatus disclosed in Japanese Patent Publication No. 6868/1993 (U.S. Pat. No. 4,751,486) a pair of rotors is rotated. Therefore, it is necessary for each of the rotors to have high precision, and in addition, measures must be taken for easier rotation control. SUMMARY OF THE INVENTION In view of the above-described problems, the object of the present invention is to provide a magnetic rotating apparatus in which rotational energy can be efficiently obtained from the permanent magnet with a minimum amount of electrical energy, and in which rotation control can be carried out relatively easily. According to one aspect of the present invention, there is provided a magnetic rotating apparatus comprising a rotating shaft; a rotor which is fixed to the rotating shaft and which has disposed thereon permanent magnet means and means for balancing rotation, the permanent magnet means being disposed such that a plurality of magnetic poles of one (or first) polarity type is arranged along an outer peripheral surface in the direction of rotation, and a plurality of magnetic poles of the other (or second) polarity type arranged along an inner peripheral surface, with each pair of corresponding magnetic poles of one and the other polarities obliquely arranged with respect to a radial line; electromagnet means, which is disposed facing this rotor, for developing a magnetic field which faces the magnetic field of the permanent magnet means of the rotor and detecting means for detecting rotating position of the rotor to allow the electromagnet means to be energized. According to another aspect of the present invention, there is provided a magnetic rotating apparatus comprising a rotating shaft a rotor which is fixed to the rotating shaft and which has disposed thereon a plurality of permanent magnets and balancers for balancing rotation, the permanent magnets being disposed such that one magnetic polarity type is arranged along an outer peripheral surface in the direction of rotation and the other magnetic polarity type arranged along an inner peripheral surface, with each pair of corresponding magnetic poles of one and the other polarities obliquely arranged with respect to a radial line; an electromagnet, which is disposed facing this rotor, for developing a magnetic field which produces the other magnetic polarity type on the facing surface; and energizing means for intermittently energizing the electromagnet means from where the leading permanent magnet, based on the rotation of the rotor, passes the facing surface of the electromagnet in the direction of rotation. According to still another aspect of the present invention, there is provided magnetic rotating apparatus comprising a rotating shaft; a first rotor which is fixed to the rotating shaft and which has disposed thereon permanent magnet means and means for balancing rotation, the permanent magnet means being disposed such that a plurality of magnetic poles of the second polarity type is arranged along an outer peripheral surface in the direction of rotation, and a plurality of magnetic poles of the first pole type arranged along an inner peripheral surface, with each pair of corresponding magnetic poles of one and the other polarities obliquely arranged with respect to a radial line; a second rotor which rotates along with the first rotor and is fixed to the rotating shaft, having disposed thereon a plurality of permanent magnets and balancers for balancing rotation, the permanent magnets being disposed such that one magnetic polarity type is arranged along an outer peripheral surface in the direction of rotation and the other magnetic polarity type arranged along an inner peripheral surface, with each pair of corresponding magnetic poles of one and the other polarities obliquely arranged with respect to a radial line a first and a second electromagnet means, which are magnetically connected and disposed facing the first and second rotors, respectively, for developing a magnetic field which faces the magnetic field of the permanent magnet means of the first and second rotors; and detecting means for detecting rotating position of the rotors to allow the electromagnet means to be energized. The nature, principle and utility of the invention will become more apparent from the following detailed description when read in conjunction with the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The magnetic field developed by an electromagnet means and that of a permanent magnet means of a rotor repel each other. In addition, the magnetic field of the permanent magnet means is flattened by the magnetic fields of other nearby permanent magnets and electromagnet means. Therefore, a torque is produced therebetween to efficiently rotate the rotor. Since the rotor has a high inertial force, when the rotor starts rotating, its speed increases by the inertial force and the turning force. A magnetic rotating apparatus related to one embodiment of the present invention will be described with reference to the following drawings. FIGS. 1 and 2 are schematic diagrams of a magnetic rotating apparatus related to one embodiment of the present invention. In the specification, the term "magnetic rotating apparatus" will include an electric motor, and from its general meaning of obtaining turning force from the magnetic forces of permanent magnets, it will refer to a rotating apparatus utilizing the magnetic forces. As shown in FIG. 1, in the magnetic rotating apparatus related to one embodiment of the present invention, a rotating shaft 4 is rotatably fixed to a frame 2 with bearings 5. To the rotating shaft 4, there are fixed a first magnet rotor 6 and a second magnet rotor 8, both of which produce turning forces and a rotated body 10, which has mounted therealong a plurality of rod-shaped magnets 9 for obtaining the turning forces as energy. They are fixed in such a manner as to be rotatable with the rotating shaft 4. At the first and second magnet rotors 6 and 8, there are provided, as will be described later in detail with reference to FIGS. 1 and 2, a first electromagnet 12 and a second electromagnet 14 respectively are energized in synchronism with rotations of the first and second magnet rotors 6 and 8, both of which face each other and are each disposed in a magnetic gap. The first and second electromagnets 12 and 14 are respectively mounted to a yoke 16, which forms a magnetic path. As shown in FIG. 3, the first and second magnet rotors 6 and 8 each have disposed on its disk-shaped surface a plurality of tabular magnets 22A through 22H for developing a magnetic field for generating the turning forces and balancers 20A through 20H, made of non-magnetic substances, for balancing the magnet rotors 6 and 8. In the embodiments, the first and second magnet rotors 6 and 8 each have disposed along the disk-shaped surface 24 at equal intervals the eight tabular magnets 22A through 22H along half of the outer peripheral area and +the eight balancers 20A through 20H along the other half of the outer peripheral area.
As shown in FIG. 3, each of the tabular magnets 22A through 22H are disposed so that its longitudinal axis 1 makes an angle D with respect to a radial axis line 11 of the disk-shaped surface 24. In the embodiment, an angle of 30 degrees and 56 degrees have been confirmed for the angle D. An appropriate angle, however, can be set depending on the radius of the disk-shaped surface 24 and the number of tabular magnets 22A through 22H to be disposed on the disk-shaped surface 24. As illustrated in FIG. 2, from the viewpoint of effective use of the magnetic field, it is preferable that the tabular magnets 22A through 22H on the first magnet rotor 6 are positioned so that their N-poles point outward, while the tabular magnets 22A through 22H on the second magnet rotor 8 are positioned so that their S-poles point outward. Exterior to the first and second magnet rotors 6 and 8, the first and second electromagnets 12 and 14 are disposed facing the first and second magnet rotors 6 and 8 respectively in the magnetic gap. When the first and second electromagnets 12 and 14 are energized, they develop a magnetic field identical in polarity to the their respective tabular magnets 22A through 22H so that they repel one anther. In other words, as shown in FIG. 2, since the tabular magnets 22A through 22H on the first magnet rotor 6 have their N-poles facing outwards, the first electromagnet 12 is energized so that the side facing the first magnet rotor 6 develops an N-polarity. In a similar way, since the tabular magnets 22A through 22H on the second magnet rotor 8 have their S-poles facing outwards, the second electromagnet 14 is energized so that the side facing the tabular magnets 22A through 22H develops a S-polarity. The first and second electromagnets 12 and 14, which are magnetically connected by the yoke 16, are magnetized so that the sides facing their respective magnet rotors 6 and 8 are opposite in polarity with respect to each other. This means that the magnetic fields of the electromagnets 12 and 14 can be used efficiently. A detector 30, such as microswitch, is provided to either one of the first magnet rotor 6 or second magnet rotor 8 to detect the rotating position of the magnet rotors 6 and 8. That is, as shown in FIG. 3, in a rotational direction 32 of the tabular magnets 22A through 22H, the first and the second magnet rotors 6 and 8 are respectively energized when the leading tabular 22A has passed. In other words, in the rotational direction 32, the electromagnet 12 or 14 is energized when starting point So, located between the leading tabular magnet 22A and the following tabular magnet 22B coincides with the center point Ro of either the electromagnet 12 or 14. In addition, as illustrated in FIG. 3, in the rotational direction 32 of the tabular magnets 22A through 22H, the first and the second magnet rotors 6 and 8 are de-energized when the last tabular magnet 22A has passed. In the embodiment, an end point Eo is set symmetrical to the starting point So on the rotating disk-shaped surface 24. When the end point Eo coincides with the center point Ro of either the electromagnet 12 or 14, the electromagnet 12 or 14 is de-energized, respectively. As will be described later, with the center point Ro of the electromagnet 12 or 14 arbitrarily set between the starting point So and the end point Eo, the magnet rotors 6 and 8 start to rotate when the electromagnets 12 and 14 and their tabular magnets 22A through 22H face one another. When a microswitch is used as the detector 30 for detecting the rotating position, the contact point of the microswitch is allowed to slide along the surface of the rotating disk-shaped surface 24. A step is provided for the starting point So and the end point Eo so that the contact of the microswitch closes between the starting point So and the end point Eo. The area along the periphery therebetween protrudes beyond the other peripheral areas of the rotating disk-shaped surface 24. It is apparent that a photo sensor or the like may be used instead of the microswitch as the detector 30 for detecting the rotating position. As shown in FIG. 4, the windings of the electromagnets 12 and 14 are connected to a DC power source 42 through a movable contact of a relay 40, which is connected in series with the windings. A series circuit containing the relay 40 (solenoid) and the detector 30 or microswitch is connected to the DC power source 42. In addition, from the viewpoint of energy conservation, a charger 44 such as a solar cell is connected to the DC power source 42. It is preferable that the DC power source 42 is constantly chargeable using solar energy or the like. In the magnetic rotating apparatus illustrated in FIGS. 1 and 2, a magnetic field distribution shown in FIG. 5 is formed between the tabular magnets 22A through 22H, disposed on each of the magnet rotors 6 and 8, and the electromagnets 12 and 14 which face them, respectively. When the electromagnet 12 or 14 is energized, a magnetic field of a tabular magnet of the tabular magnets 22A through 22H, adjacent to the electromagnet 12 or 14, is distorted in the longitudinal direction in correspondence with the rotational direction. This results in the generation of a repulsive force therebetween. As is apparent from the distortion of the magnetic field, the repulsive force has a larger component in the longitudinal or perpendicular direction, and produces a torque, as shown by an arrow 32. Similarly, a magnetic field of a tabular magnet of the tabular magnets 22A through 22H, which next enters the magnetic field of the electromagnet 12 or 14, is distorted. the repulsive force produced between the tabular magnets of the tabular magnets 22A through 22H, which have already entered the magnetic field of the electromagnets, a repulsive force operates between both of the poles M and M' of the tabular magnet at the rotating side and the electromagnet at the stationary side, respectively. Therefore, from the relationship illustrated in FIG. 6, an angular torque T is generated based on the formula: T=F. a.cos (.alpha.-.beta.), where in a is a constant. The angular torque starts the rotation of the rotating disk-shaped surface 24. After the rotating disk-shaped surface 24 has started rotating, its rotating speed gradually increases due to an inertial moment thereof, which allows a large turning driving force to be produced. After a stable rotation of the rotating disk-shaped surface 24 has been produced, when a necessary electromotive force can be developed in an electromagnetic coil (not illustrated) by externally bringing it near a rotated body 10 to be rotated along with the rotating disk-shaped surface 24. This electric power can be used for other applications. This rotating principle is based on the rotating principle of the magnetic rotating apparatus already disclosed in Japanese Patent Publication No. 61868/1993 (U.S. Pat. No. 4,751,486) by the inventor. That is, even if an electromagnet, provided for one of the rotors of the magnetic rotating apparatus disclosed in the same Patent Application, is fixed, it is rotated in accordance with the rotating principle disclosed therein. For details, refer to the above Japanese Patent Publication No. 61868/1993 (U.S. Pat. No. 4,751,486).
The number of tabular magnets 22A through 22H is not limited to "8" as shown in FIGS. 1 and 3. Any number of magnets may be used. In the above-described embodiment, although the tabular magnets 22A through 22H are disposed along half of the peripheral area of the disk-shaped surface 24, and the balancers 20A through 20H are disposed along the other half of the peripheral area, the tabular magnets may further be disposed along other areas of the disk-shaped surface 24. It is preferable that balancers, in addition to magnets, are provided along a portion of the peripheral area on the disk-shaped surface. The counter weights, which do not need to be formed into separate blocks, may be formed into one sheet of plate which extends on the outer peripheral area of the disk-shaped surface. In addition, in the above-described embodiments, while the construction is such as to allow the electromagnets to be energized for a predetermined period of time for every rotation of the rotating disk-shaped surface, the circuit may be so constructed as to allow, upon increased number of rotations, energization of the electromagnets for every rotation of the rotating disk-shaped surface, starting from its second rotation onwards. Further, in the above-described embodiment, a tabular magnet has been used for the permanent magnet, but other types of permanent magnets may also be used. In effect, any type of magnet may be used as the permanent magnet means as long as a plurality of magnetic poles of one type is disposed along the outer surface of the inner periphery and a plurality of magnetic poles of the other type are disposed along the inner peripheral surface of the disk-shaped surface, so that a pair of corresponding magnetic poles of one and the other polarities is obliquely arranged, with respect to the radial line 11, as shown in FIG. 3. Although the tabular magnets 22A through 22H are mounted on the magnet rotors 6 and 8 in the above embodiment, they may be electromagnets. In this case, the electromagnets 12 and 14 may be the alternative of electromagnets or permanent magnets.
According to the magnetic rotating apparatus of the present invention, rotational energy can be efficiently obtained from permanent magnets. This is made possible by minimizing as much as possible current supplied to the electromagnets, so that only a required amount of electrical energy is supplied to the electromagnets. It should be understood that many modifications and adaptations of the invention will become apparent to those skilled in the art and it is intended to encompass such obvious modifications and changes in the scope of the claims appended hereto. KeelyNet: BBS Posting from Henry Curtis (11-18-1997)
Korean Magnetic Perpetual Motion Wheel I must apologize for not having all the details of this interesting device but will update the file when I get more info from the source. In email communications with John Schnurer, I happened to mention it and he's been on me since then to send him a diagram, yet I felt like it would simply be confusing because its operation is not clear or readily apparent from the information I had.The information that I have comes directly from long time friend Henry Curtis of Colorado. We both attended the 1997 ISNE conference in Denver and Henry was telling about this interesting machine he had seen while on a trip to the Phillipines. He said there was a free energy conference held there and he noticed a spinning bicycle wheel that was attached to a stand that sat on a table.The wheel was running when he first saw it, yet there did not appear to be any driving force such as a motor, belts, gears, etc..Henry said he watched it for quite awhile and it never stopped running. On expressing curiosity about the wheel, he was invited to stop it and start it up without any outside assistance.Henry reports the wheel was brought to a complete stop, then he gave it a spin with his hand and it began moving on its own. I am uncertain if it followed the tendency of other such devices to establish its own speed. Some devices like this can be spun up to high speed from an outside source, then will slow to a speed which is determined by the geometry and strength of the repelling or attracting forces that operate it.Henry swears it was the neatest thing he'd ever seen and drew a crude diagram of the arrangement on my notepad. Unfortunately, we were a bit rushed and I did not achieve a complete understanding of how it operated. That is why I did not want to blow smoke about it until more detail had been received, god knows, we don't need any more of that.However, perhaps someone can figure it out from the limited information I do have. The following drawing shows the wheel arrangement, one half was weighted, the other half had slanted magnets. I do not know whether they are all repelling, attracting or a mix of these forces. As you can imagine, the weight of the magnets must equal the weight of the other half of the wheel to balance out. Apparently the force of the magnetic repulsion or attaction provides the actual imbalance.Henry also said there was a patent on this device that is dated January 14, 1997. The inventor is a Japanese man named Minatu. The spelling of this name is uncertain. I did a search on the IBM server but found nothing even remote. Henry specifically said this was a United States patent. So, here it is. Perhaps Henry can come up with some more detail which can be used to update this file in future. Good luck.... KeelyNet: Update and Corrections from Henry Curtis (Wed, 19 Nov 1997) ~
From: Henry Curtis ~ To: Jerry Decker Subject: Bicycle wheel correction and update Jerry, Again we see that communication is difficult and memories are fallable. Obviously I am remiss in not having sent this to you months ago as I intended to, but as a sage of old observed "The spirit is willing, but the flesh is slow." During the first weekend of May, 1997, a group in Soeul, Korea headed up by Mr. Chi San Park, held The First International New Energy Conference in Seoul, Korea. I attended this conference and gave a talk on various approcahes to free energy. It was at this conference in Seoul, Korea that I saw the bicycle wheel and had the opportunity to work with it unattended by anyone else.The inventor is Kohei Minato, a Japanese rock musician, who reports that he has spent a million dollars out of his own pocket developing magnetic motors, because the world needs a better source of energy. He has several patents in various countries. His latest patent that I am aware of is United States Patent # 5,594,289. His development efforts have gone in the general direction of the Adams motor which the above patent is similar to. He had a working prototype of this design at the conference and reported that it used 150 watts power input and produced 450 watts output on a sustained basis. About a year ago CNN (in the US) had a 10 minute segment about him and his motors. In this video he is shown demonstrating two of his magnetic motors. I have a copy of this film clip that he gave to me. I will make a copy and send it to you. Unfortunately, the editors were not attuned to technical details and the pictures of the running machines show little useful detail. The Phillipine connection that you mention is completely erroneous. It was in Korea. The drawing on the web site is essentially correct with the following exceptions. The counter weight is a single curved piece of aluminum covering 180 degrees. Each of the several individual magnets on the other half of the wheel are slightly asymmetric, crescent shaped and nested. They are magnetised end to end with the N poles out. The motor is actuated by moving the N pole of a large permanet magnet (the drive magnet) toward the wheel. As this magnet is moved toward the wheel, the wheel starts to spin. As the magnet is moved closer to the wheel it spins faster. The acceleration of the wheel is rapid. So rapid in fact, as to be startling. To put it another way I was very impressed. The motor works. And it works very well. In the film clip a slight pumping action of Minato's hand holding the magnet is apparent. When I braced my hand so that there was no pumping action, the motor still ran. In fact it seemed to run better. Pumping action by the hand held magnet is not the power that drives the motor. When the drive magnet is moved away from the wheel it coasts rather quickly to a stop and comes to rest in a manner typical of any spinning bicycle wheel. Again when the wheel is at rest and a large magnet is moved up to the wheel it starts to spin. At no time is it necessary to touch the wheel to get it to rotate. Simply bring the N pole of a large magnet several inches from the wheel. The particular orientation of the wheel when it is at rest seems to have no effect on how well it starts to turn. Irrespective of how the wheel and the magnets on it are sitting; move the drive magnet near, it starts to spin. Move the magnet closer it spins faster. Move the magnet further away it slows up. The wheel was mounted on a stand made of aluminum angle pieces bolted together similar to the diagram in the above mentioned patent. The axle of the wheel was mounted parellel to the surface of the planet. I have attached a rough diagram of the wheel. Apparently the geometry of the magnets on the wheel is very important and subtle. I have built several small models none of which have shown the free energy effects of Minato's machine. The conference in Seoul was attended by several hundred people, most appeared to be under 40 and evenly divided between men and women. Presenters were from Korea, US, Japan, and China. Simultaneous translation was provided for all talks in the 3 day conference. Jerry, I hope this information is useful. I may be contacted by e-mail at mailto:hcurtis@mindspring.com or by phone at 303.344.1458.
KeelyNet: Email from Gene Mallove at Infinite Energy ~ I spoke to Bob Vermillion of Tri-Cosmos Development (Los Angeles, CA 310-284-3250 or fax 310-284-3260) today, just before he left for the three-day demonstrations of the Minato magnetic motor being held in Mexico City, Mexico on July 8, 9, 10th.Three (3) Minato Motors (MM), covered by US Patents # 5,594,289 (Jan 14, 1997) and # 4,751,486 (June 14, 1988), have been brought over from Japan. One was allegedly tested last evening by Grupo Bufete Industrial (supposedly one of the largest power generation construction companies in Mexico and South America). The company engineers were said (by Vermillion) to have measured an output /input ratio of 4.3 / 1. The printed literature, which I received in a Fedex packet from Vermillion states that the device can put out 500 watts (maximum) with an input of 34 watts.For those of you who wonder why the device is not self-sustaining -- oral info from Vermillion is that Minato *will* in the course of one of the demonstrations *remove the battery power supply* and let the device self-run -- presumably with a load. The press release makes no bones about the physics-busting character of the MM: "As rotations per minute (rpm's) increase, the electromagnetic consumption of the stator decreases. This phenomenon is in direct conflict with accepted laws of physics and is achieved through the repelling magnetic fields. It operates without heat, noise, or pollution of any kind. It can be produced in size from ultra-small to very large." It is said in the press release that applications from cell phones to laptop computers are under development. Vermillion told me of other parties who were planning to attend the demonstrations, which will be conducted both in public displays and with private party measurements. These include: ENRON, Bechtel, Tejas (a division of Shell Oil Corporation), Fluor Daniels, Kellogg Corp. .He told me that Hal Fox of New Energy News and the Fusion Information Center will be there (I confirmed with Hal that he will be there and will give us a full report.) I considered going myself (I was invited), but I trust Hal Fox to provide a full report --
Heel soms komt het voor dat het materieel zo door de war zit dat er bijzondere maatregelen nodig zijn om alles weer in het gareel te krijgen. Dat kan komen door een versperring op een eerder moment, waardoor bijvoorbeeld lange spitstreinen moesten keren naar rustige oorden en te korte treinen de andere kant op schoten. Maar ook veel defecten binnen één soort mterieel maakt dat er wel eens ander materieel moet worden ingezet om alle treinen te kunnen blijven rijden.
In dit seizoen van de vallende blaadjes ontstaan er gladde sporen. Die maken dat treinen gaan glijden, en dat de wielen op één klein plekje afslijten als hele assen blokkeren. Als dat is gebeurd dan hoor je vaak een kenmerkend gebonk onder draaistellen vandaan komen. Zulke assen moeten dan weer rond geslepen worden, en dat kost twee uur per as. Heel soms wil het wel eens voorkomen dat er 30 assen onder één trein beschadigd raken (vlakke plaatsen), Dat kan bijvoorbeeld bij een IC Direct , die tot wel 44 assen per trein heeft. Zulke treinen houden dan de slijpmachine 5 hele dagen non-stop bezet. En dat terwijl er in dit seisoen dagelijks treinen vlakke plaatsen oplopen.
Wat afgelopen week ook de reden was, NS voelde zich genoodzaakt om een ICM in te zetten in de sprinterdienst. Ik kreeg van een lokale spotter tijdig een seintje en ging naar het station om de in- en uitstappende reizigers vast te leggen. Zie hier het resultaat.
i decided not to jogging today...
1. the track is wet!
2. the sky is grey... in a minute the rain will come again!
sollutions :
1. organize my stuffs in my bag! hehehe
i put my allergy pills just in case i eat seafood/extreme weather causing me itchy
2. clean up my harddisk
3. read books :P
This is one of those shots that instantly puts me there. Taken right in the midst of the crowds in Tomorrowland after a storm had just passed with the sky turning a deep blue and the lights of Tomorrowland beginning to come alive, I took this series of shots during one of those "ahhh" moments. Sarah and I normally don't slow down, let alone stop what we're doing, for photography, but on this night when we saw the sky, we knew it was time to head to Tomorrowland and just take it all in, and snap some pictures.
It really was difficult to bring the camera to my eye for these shots. So much of me wanted to just stand there and listen to the background music as it all passed by. For a good amount of time, that's exactly what I did. This is one of those shots that reminds me of what I love about WDW so much--even if I don't love what's on the right in this shot ;-)
It's really one of those shots that gets me excited for returning to the World. I can't believe I'll be standing in a Park a week from today!!!

Another day where I just put on stuff until I was satisfied ! This sweater is from Fri.day and it's just adorable. My RL partner told me that this look is really more like "the real me at home" and that is true, except that my sweatpants are usually covering my legs ;). I never really look the way I look in my everyday life though, at work or outside. Maybe I should give it a try ? Or maybe that would be too normal ? Idk !

The vertical seat part is not legally put on, but this way it gives the tension to make the whole parts held tight.
Barbara & Jim were 2 of my friends at UMKC. This was taken just outside the dorm on a nice April day.
I am finding it impossible to decide on Hawk IDs!!! I have put two different photos of an individual on Google Lens. One photo is identified as a Swainson's and the other as a Red-tailed, sigh. Thanks to friends, Sandi and Jackie, it turned out to be a juvenile Swainson's Hawk. The hawk in the photo above is of the adult that I saw first, along this gravel road. She flew off after a short while and I didn't think anything of it. However, when I came back in the opposite direction on this road, I glanced at the spot I had seen her, and there, to my surprise, were two juvenile siblings tucked into the corner of the field by the fence.
Further on, another two siblings were seen and judging by their behaviour, they would seem to be Swainson's Hawks. While driving along a back road after another visit to the Saskatoon Farm (previous visit was on 13 September 2024), I spotted a hawk down on the gravel road way ahead of my car. Pulling forward very slowly and cautiously, I took a few ID shots. My first thought was that perhaps it was injured, as I never see a hawk down on the road and I definitely didn't want to risk making it fly. Then I looked through the windscreen and was surprised to see a second hawk on the road! Passing the first hawk, I pulled over to watch the second bird. After a little while, this second hawk 'flew' for a second, barely above the ground. Then it walked to my car and stayed there. It did give one quick call to an unseen adult, but I didn't hear any answer. I can't imagine Red-tailed hawks doing this, as they tend to fly away almost as soon as they see my car.
Shortly before this experience, I had seen an adult hawk on a fence post but only managed a few quick ID shots before it flew. This was about an 11 minutes' slow drive further south on the same road. Driving past the spot in the other direction some time later, i glanced at the corner of the field where I had seen the adult hawk fly from, and there, down on the ground, were two young hawks. I don't know if these youngsters could be the same ones I saw further north or not. I wonder if their flying skills would be good enough to fly that distance.
"Breeding densities may vary from one area to the next but averages one pair per 2.5 sq mi (6.5 km2). The average home range estimate for this hawk is 1 to 2 sq mi (2.6 to 5.2 km2)."
From Wikipedia.
First thing in the morning on this day, 16 September 2024, I made a return visit to the Saskatoon Farm. They had just had a busy, special weekend at the Farm and I wanted to see and take photos of some of the pumpkin displays that were not out on 13 September. I always like to support the Farm, so I enjoyed a breakfast that I knew would keep me going for a few hours.
Very little in the way of birds to be seen on this drive, though I did see several other hawks. Birding has definitely slowed down - can't wait for next spring!
