  • Patent number: 10535483
    Abstract: In an electromagnetic relay device, a stationary core is coaxially arranged in an exciting coil, and constitutes a magnetic circuit. A yoke is arranged to surround an outer periphery of the exciting coil and the second end of the exciting coil to constitute the magnetic circuit. The yoke has an opening that is located to be closer to the first end of the exciting coil than to the second end of the exciting coil, and that faces the stationary core. A movable core is located to face the stationary core via the opening. The movable core is pulled to the stationary core upon the exciting coil being energized. A return spring is made of a magnetic member that is volutely wound in an axial direction of the stationary core. The return spring urges the movable core to be separated from the stationary core.

  • Patent number: 10522277
    Abstract: A diamagnetic levitation system having an open torus magnet segment with a pair of arms extending from a central base. The ends of the arms form a gap. The arms are superconducting magnets and the base is an electromagnet. The magnet segment creates a planar magnetic field which forms a flat ellipse as the planar magnetic field crosses from one arm to the other and which is positioned only across the gap. The electromagnet oscillates the planar magnetic field. The magnet segment levitates a diamagnetic object within and/or above the gap. A plurality of magnet segments can be arranged in series to form a levitation system of defined length. The magnet segments are rotatable so that the planar magnetic field may be tilted.

  • Patent number: 10522313
    Abstract: A reversing linear solenoid polarized in a permanent magnetic manner having a first and second end stroke position as well as at least one armature, wherein it has a spring system or is operated at such a spring system which exerts a force in the direction of the center stroke position on the armature or armatures in the end stroke position(s). The spring system and the reversing linear solenoid are coordinated with one another such that the armature or armatures are held in a permanent magnetic manner against the spring force in both end stroke positions. The spring system is configured such that the potential energy (elastically) stored by movement of the armature or armatures into its/their end stroke movements is of equal magnitude. If external restoring forces caused by the application are present, they must be taken into account in the design of the spring system.

  • Patent number: 10491078
    Abstract: A linear motor heat dissipation structure including multiple teeth arranged linearly at predetermined intervals each with coil wound around rectangular tube-shaped bobbin, and heat dissipation member provided between adjacent coils that dissipates heat generated coils by transmitting the heat to an external section. Heat dissipation member is sandwiched by bowed sections of coils that are curved outwards within edges of rectangular tube-shaped bobbin due to elastic force of coils. Accordingly, even when there are component tolerances and assembly tolerances, those tolerances are absorbed by the elastic deformation of the bowed section of coils such that the variance in the contact state between coil and heat dissipation member is made smaller so that stable and high heat dissipation performance is achieved.
