Le musee se devoile en exposant sa collection permanente.
Chacune des oeuvres est une porte d'entree sur l'univers d'un artiste ou sur le souvenir d'une exposition. Rassemblees par le MIMA, elles donnent une image de la creation contemporaine, de l'esprit creatif de l'epoque, d'un 'Zeitgeist' du Millenium.
La caverne
Les oeuvres rassemblees au premier etage ont ete produites par des artistes qui n'ont pas exposes ici. Elles ont ete acquises, pour la plupart, avant l'ouverture du MIMA en 2016.
Symboliquement cet etage est baptise la 'caverne' en clin d'oeil a l'allegorie platonicienne critiquant notre connaissance biaisee de la realite. Dans le mythe, des hommes au fond d'une grotte prennent les ombres sur les murs pour la realite. Ces illusions du reel, sont comparables pour le MIMA aux peintures du premier niveau qui vantent une culture filtree par les ecrans et les livres plutot qu'experimentee sur son propre terrain d'exposition.
Le terrain de jeu
Les travaux presentes au deuxieme etage sont comme des jouets laisses par les artistes exposes au MIMA.
A partir de 2016, la collection devient un miroir imparfait du passe ou tous les artistes et toutes les expositions de l'institution n'y figurent pas pour de nombreuses raisons. En pointille se dessine la le portrait societal raconte par l'institution.
Les champs Elisee
Le projet museal du MIMA sera-t-il encore adapte a son epoque apres dix ans d'activite?
Pour y repondre, le musee annonce sa fermeture definitive a la fin de 2026!
En se fixant une deadline a sa propre existence, le musee s'impose une remise en question qui aboutira soit a se reinventer, soit a disparaitre.
L'installation du troisieme etage imagine l'heritage que laisserait le MIMA s'il ferme ses portes en 2027.

To celebrate its 550th anniversary Magdalen College, Oxford has commissioned the Turner Prize-winning artist Mark Wallinger to create his first-ever dedicated permanent artwork.
Two years in development, the sculpture Y was unveiled on St Mary Magdalen Day 2008. William Waynflete, Bishop of Winchester founded Magdalen College in 1458. It is one of the best-known colleges in the University of Oxford and is known internationally for its high academic standing.
The College has many fine buildings. The Cloisters, Chapel, Founder’s Tower and Hall were built in the Gothic style in the later part of the 15th century. The Great Tower, a pictorial symbol of Oxford, is famous for the May Day event when the College choir sings an ancient hymn at dawn. The Georgian New Buildings, which blend into the College Gardens and grounds, were completed in 1733. The buildings sit amid a hundred acres of lawns, woodlands and riverside walks, which are publicly accessible, and there is a deer herd that has been in existence for over 300 years.
Addison’s Walk, named after the great essayist of the 18th century and father of English journalism, is about a mile in length and goes by the River Cherwell around a great water meadow. Beyond the end of Addison’s Walk is a tranquil field known as Bat Willow Meadow, which is where the new commission is sited. Maps of the grounds of Magdalen College are available from the Porters’ Lodge or they can be downloaded from the Magdalen website.
Over the past twenty years Mark Wallinger has established an international reputation with major solo exhibitions in London, Birmingham, Liverpool, Val-de-Marne, Frankfurt, Aarau, Basel, Milan, New York and Chicago.
His work encompasses a wide range of media, including painting, photography, sculpture, video and installation, and it takes art history, mythology, religion, politics, national identity and popular culture as its subject matter. Wallinger studied at Chelsea School of Art in 2001, and in Goldsmiths' College. He exhibited in Young British Artists II at the Saatchi Collection in 1993 and at the Royal Academy of Art's Sensation exhibition in 1997.
His Time and relative dimensions in space derived from a residency and was shown at Oxford University Museum of Natural History in 2001 and in the same year he represented Britain in the 49th Venice Biennale. The artist is best known for Ecce Homo, a life-size sculpture of Jesus Christ which inaugurated the Fourth Plinth in Trafalgar Square in 1999, and State Britain, his 2007 re-creation at Tate Britain of Brian Haw's protest display outside parliament. He was a Turner Prize nominee in 1995 and won the award in 2007, and he is one of five internationally acclaimed artists who have been commissioned to produce proposals for the Ebbsfleet Landmark Project, which will be one of the biggest artworks in the United Kingdom.
The song from TRAIN:
"......Tell me did you sail across the sun
Did you make it to the milky way to see the lights all faded
And that heaven is overrated
But tell me, did you fall for a shooting star
One without a permanent scar
And did you miss me while you were looking for yourself out there......"

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.

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. 1 is a schematic perspective view showing a magnetic rotation apparatus according to an embodiment of the invention;
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. Each of the permanent magnets is obliquely arranged with respect to the radial direction line of the rotor. At the outer periphery of the rotor, an electromagnet is disposed facing this rotor, with this electromagnet intermittently energized based on the rotation of the rotor. 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. 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.
BRIEF DESCRIPTION OF THE DRAWINGS In the accompanying drawings: FIG. 1 is a perspective view schematically illustrating a magnetic rating apparatus according to one embodiment of the present invention FIG. 2 is a side view of the magnetic rotating apparatus illustrated in FIG. 1; FIG. 3 is a plan view of a rotor of the magnetic rotating apparatus illustrated in FIGS. 1 and 2;
FIG. 4 is a circuit diagram illustrating a circuit in the magnetic rotating apparatus shown in FIG. 1; FIG. 5 is a plan view showing a magnetic field distribution formed between the rotor and the electromagnet of the magnetic rotating apparatus shown in FIGS. 1 and 2, and FIG. 6 is an explanatory view illustrating a torque which causes rotation of the rotor of the magnetic rotating apparatus shown in FIGS. 1 and 2. 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.)

Mark Twain , USA Philosophizing Writer Quotes
Born November 30, 1835; Died April 21, 1910
It's no wonder that truth is stranger than fiction. Fiction has to make sense.
It's not the size of the dog in the fight, it's the size of the fight in the dog.
Kindness is the language which the deaf can hear and the blind can see.
Laws control the lesser man... Right conduct controls the greater one.
Let us live so that when we come to die even the undertaker will be sorry.

Responding to an admirer today, I shared these secrets:
Appreciation much for your fine words.
With my two Point and Shot cameras (about $240 each), I am having a ball.
Having taken over 120,000 fotos, I have deleted many not so good.
I try to upload only the best in my eyes. Sometimes others agree.
My secrets::
1. take lots of same subject if you can from many different angles; and
2. use Google's free Picasa2 when you need to edit or crop, etc.
Be sure to maintain LIFE in good balance, for this Flickring can take up your whole day and night each 24 hours if you are not careful. GET BALANCE!

Out of our Heads
Lyrics: Bill Bottrell/CrowMusic: Bottrell
If you feel you wanna fight me
There’s a chain around your mind
When something is holding you tightly
What is real is so hard to find
Losing babies to genocide
Oh where’s the meaning in that plight
Can’t you see that we’ve really bought into
Every word they proclaimed and every lie, oh
If we could only get out of our heads, out of our heads
And into our hearts
If we could only get out of our heads, out of our heads
And into our hearts
Someone’s feeding on your anger
Someone’s been whispering in your ear
You’ve seen his face before
We’ve bee played before
These aren’t the words you need to hear
Through the dawn of darkness blindly
You have blood upon your hands
All the words will treat you kindly
But only the heart can understand, oh understand
If we could only get out of our heads, out of our heads
And into our hearts
Children of Abraham lay down your fears, swallow your
tears and look to your heart
If we could only get out of our heads, out of our heads
And into our hearts
Children of Abraham lay down your fears, swallow your
tears and look to your heart
Every man is his own prophet
Oh every prophet just a man
I say all the women stand up, say yes to themselves
Teach your children best you can
Let every man bow to the best in himself
We’re not killing any more
We’re the wisest ones, everybody listen
‘Cause you can’t fight this feeling any more, oh anymore
If we could only get out of our heads, out of our heads
And into our hearts
Children of Abraham lay down your fears, swallow your
tears and look to your heart
If we could only get out of our heads, out of our heads
And into our hearts
Children of Abraham lay down your fears, swallow your
tears and look to your heart

Cockburn Town is the capital city of the Turks and Caicos Islands.
Cockburn Town is located on the largest island in the Turks Islands archipelago, Grand Turk Island. Historic 18th and 19th century Bermudian architecture line Duke and Front Streets in the town. The town is known for its long, narrow streets and old street lamps.
The closest anchorage to Cockburn Town is Hawk's Nest Anchorage, which, though sheltered, should only be entered in good light because of reefs near the entrance.
The seat of government ever since 1766, Cockburn Town was the first permanent settlement on any of the islands, founded in 1681 by salt collectors who arrived in the Turks and Caicos Islands. The city supposedly lies on the place where Juan Ponce de León first landed on the island.

The art installation in Piazza Giuseppe Verdi is a permanent public work titled Intervento per Piazza Verdi, created by the internationally renowned French conceptual artist Daniel Buren.
Completed in early 2017 as part of a major architectural and artistic redevelopment of the square led by architect Gianantonio Vannetti, the installation completely transformed the space into a pedestrianized urban living room.
Key Elements of the Installation:
• The Colored Arches: The installation features a rhythmic succession of large, flat, geometric portals or arches spanning a central pedestrian walkway. They are painted in alternating vivid primary and complementary colors, interspersed with Buren’s signature vertical white-and-black stripes.
• Mirrors and Perspectives: Many of the arches incorporate mirrored surfaces, creating a playful interplay of reflections that constantly reframe the surrounding architecture as you walk through them.
• Night Lighting: At sunset, the entire installation shifts character. Colored LED lights built directly into the base of the arches illuminate the structures from below, turning the square into a dynamic, glowing light path.

An old photograph of a Leeds City Tramways (LCT) tramway crane derrick at the Sovereign Street Permanent Way Yard.
A version hand colourised by me is here:-
'Leeds Transport' by Jim Soper says this particular crane was built by Joseph Booth & Bros of Rodley in 1922, the cab with two rows of windows being built by LCT. To help with the scrapping of trams it was moved to Lowfields Road Permanent Way Yard on 30/31 Jan 1956 where it worked until being broken up at an unknown date. The earlier 1910 crane had one line of cab windows whereas this 1922 one had two lines of windows. Although I have a photo of a crane at Lowfields and it has only one row of windows?
The photo reverse is stamped with the photographer (and/or negative owner) name Robert F. Mack (aka Bob Mack).
If there are any errors in the above description please let me know. Thanks.

The linoleum flooring shows the names inset. This was a permanent design in the linoleum. Back in the day, people with those tiny Capes and Minimal Traditionals, had to do something with multiple children, especially if they had both genders. The big advantage is that kids actually did learn to get along.
Just a closeup of the signage on one of the recently decommissioned kiosks in the photo center. Look for more photos from this Sam's Club from me soon (and plenty from Retail Retell to come as well), though with Walmart's concept of time when it comes to remodels, who knows exactly when things will start getting good with this one!
UPDATE 2: Well, per yet more info obtained by Retail Retell (who else !!?), this remodel is set to get underway in just a couple of weeks or so...
