Abstract: A revolution assisting device for a rotating body comprises the rotating body provided on an outer peripheral surface thereof with permanent magnets, and a shaft connected to the rotating body by means of a crank mechanism and provided with permanent magnets, the shaft effecting vertical movements to assist revolution of the rotating body.

Abstract: The present invention relates to an electromagnetic piston engine capable of producing driving power by a reciprocal movement of a piston in a cylinder by electromagnetic force. The present invention has the objects to provide the electromagnetic piston engine which can do without a variety of resistance inherent in internal combustion piston engines, which reduces the weight corresponding to a rotary assembly portion to a smaller value even if a great output is produced, which can be readily employed together with power transmission mechanisms and so on for use with conventional internal combustion piston engines, and which has a high efficiency in energy consumption.

Abstract: A completely novel rotary apparatus is provided which can rotate a composite rotor at a high speed by utilizing the magnetic force, the composite rotor being comprised of a plurality of ring-shaped rotors arranged concentrically with each other.

Abstract: A device for rotating a layered body includes multiple rotating plates arranged in equally spaced layers and coaxially aligned about an axis of rotation. Facing plate surfaces between each pair of neighboring plates form a gap between neighboring plates. At least one magnetic pole is provided on each plate surface that forms a gap. The magnetic poles being arranged such that the polarities of magnetic poles on facing surfaces in each gap are the same. When the rotating plates are stationary, the at least one magnetic pole on one plate is arranged to occupy an alternating position with a corresponding magnetic pole on the facing surface of the neighboring plate.

Abstract: A rotary electric machine of an inner rotor type includes a hollow stator having multiple field magnets, each having a magnetic pole, arranged in a spaced relationship along a circumferential direction on an inner surface of the stator such that all inward-facing magnetic poles of the field magnets have the same polarity. A cylindrical rotor is arranged concentrically inside the stator such that a gap separates the rotor from the stator. The rotor has multiple magnetic pole generators, each comprising a rotor winding wound on a core, arranged in a spaced relationship along a circumferential direction on a outer surface of the rotor such that the magnetic pole generators oppose, and are separated by the gap from, the field magnets on the inner surface of the stator.
