  • Patent number: 11357094
    Abstract: A deflection electromagnet device generates a high magnetic field without increasing the size of a vacuum duct to facilitate control over a beam orbit. Magnetic flux lines from a return pole pass through the vacuum duct of a high-temperature superconductor in a vacuum heat insulation container and the charged particle beam is thus deflected, thereby generating radiation. A three-pole magnetic field is formed on the beam orbit and the charged particle beam is thus deflected by individual magnetic fields, so that radiation can be generated while the charged particle beam returns to a coaxial orbit. Therefore, an increase in size of the vacuum duct can be prevented. A shielding current is dominant and the non-uniformity of the magnetic field in a z-axis direction is prevented by disposing the high-temperature superconductor having a crystal direction c-axis orthogonal to a horizontal plane in which the charged particle beam flows.

  • Patent number: 11342103
    Abstract: De-magnetization protection is provided for electro-permanent magnets during information handling system manufacture and use by monitoring thermal conditions at the information handling systems to detect a thermal state associated with de-magnetization and commanding the electro-permanent magnets to an off state so that both magnets in the electro-permanent magnet have opposing polarities. The opposing polarities tend to stabilize magnet polarity to prevent de-magnetization during increased temperatures. Normal operations are then re-enabled once temperatures decrease.

  • Patent number: 11309769
    Abstract: A disclosed electrical generator includes a housing, an actuator, a rotatable member, a stator, a rotor, an electrical circuit, and a current controller. The actuator is movable relative to the housing and the rotatable member is also rotatable relative to the housing. The rotatable member cooperates with the actuator such that movement of the actuator causes rotation of the rotatable member. The stator is fixed relative to the housing and the rotor receives rotational kinetic energy from the rotatable member. Movement of the rotor relative to the stator generates electromagnetic induction in the rotor and/or the stator which produces a three-phase alternating current. The electrical circuit includes a rectifier that converts the alternating current to a direct current. The current controller regulates the direct current to thereby generate a fixed constant direct current.
