  • Patent number: 6051902
    Abstract: A magnetic attraction driving engine utilizing a permanent magnet is provided with a permanent magnet, an electromagnet formed by winding a coil on a magnetic core with one end thereof stuck to one magnetic pole end of the permanent magnet, an excitation controller for exciting the electromagnet to change a state of magnetic fluxes in the vicinity of the magnetic pole end of the permanent magnet, a movable member having magnetic attractivity set in the vicinity of the magnetic pole end of the permanent magnet by being supported and guided so as to be capable of coming close to or separating away from the permanent magnet and a returning force applying member for causing by pressure the movable member to retreat against a magnetic attracting force and move back and forth by changing a magnetic attracting force of the permanent magnet.

  • Patent number: 5926083
    Abstract: A static magnet dynamo including at least one permanent magnet having different poles; a first core comprising a soft magnetic material and which couples the different poles of the permanent magnet to form a closed magnetic path therein; a second core comprising a soft magnetic material which couples to the closed magnetic path via a paramagnetic material to form an open magnetic path; a magnetized coil wound around a portion of the first core where the closed magnetic path is formed; and an induction coil wound around a portion of the second core. A direction of a flux of the closed magnetic path is changed by applying an alternating voltage to the magnetized coil, generating an electromotive force in the induction coil by electromagnetic induction due changes in a flux of the open magnetic path induced by the change in direction of the flux of the closed magnetic path.

  • Patent number: 5804901
    Abstract: An energy-conversion device using permanent magnets in which there is 1) an attraction magnetic field generating device constituted by connecting the two poles between an electromagnet made by wrapping exciting coils around magnetic yokes and permanent magnets parallelly installed with the electromagnets and 2) magnetic attracted blocks supported parallelly to the said attraction magnetic field generating device and in which poles in the same direction as or in the opposite direction to the permanent magnets are produced by pressing the said exciting coils with positive or negative direct current, accordingly causing the said attracted blocks to be attracted or released and thereby converting electric energy to kinetic energy.
