Title: Hiroshi Imaizumi: Innovator in Superconducting Technology
Introduction
Hiroshi Imaizumi is a notable inventor based in Suwa, Japan. He has made significant contributions to the field of superconducting technology, holding a total of 2 patents. His work focuses on advanced bearing devices that utilize superconductors and magnets to enhance performance.
Latest Patents
One of his latest patents is a superconducting bearing device. This device comprises a superconductor mounted on a stationary member and a magnet section that is mounted on a rotating member. The superconductor and the magnet section are arranged to oppose each other with a gap in between. The patent also details a method for producing the magnet section, which consists of multiple annular permanent magnets that are concentric with the axis of the rotating member. Additionally, at least one soft magnetic yoke is included between these annular permanent magnets. Each annular magnet may consist of several arcuate magnet portions, with their joint surfaces either concentrically or axially staggered to mitigate nonuniform flux densities at their junctions. The design also incorporates curved or slanted joint surfaces to reduce axial displacement during rotation. Furthermore, the yoke members are designed to protrude towards the superconductor, optimizing the concentration and direction of magnetic flux. Restraining members or wedge portions may also be fitted to the magnet section to prevent displacement and breakage at high rotational speeds.
