Latest Patents
Ota holds a patent for a method titled "Process for producing a rare earth-iron-boron magnet." This novel process comprises several intricate steps. Firstly, it involves charging a melt spun powder of a rare earth-iron-boron magnet into a cavity defined by electrodes situated within a non-conductive ceramic die. The next step entails subjecting this powder to a non-equilibrium plasma treatment under a controlled atmosphere of 10^-1 to 10^-3 Torr while applying substantial uniaxial pressure between 200 and 500 kgf/cm². This phase serves to fuse the melt spun powder effectively. Finally, Ota's process requires the heated fused powder to reach its crystallization temperature, utilizing Joule's heat to promote plastic deformation and solidify the rare earth-iron-boron magnet.
