Title: Innovations by Takenobu Yoshimatsu
Introduction
Takenobu Yoshimatsu is a notable inventor based in Tokai, Japan. He has made significant contributions to the field of rare earth magnet technology. With a total of 2 patents, his work focuses on improving production methods and apparatuses for anisotropic rare earth magnet powders.
Latest Patents
Yoshimatsu's latest patents include a production apparatus for rare earth anisotropic magnet powders. This innovative apparatus provides continuous hydrogen heat treatment to anisotropic rare earth magnet powders. It consists of a shopper, a furnace for hydrogen heat treatment, a heat compensating means to maintain a constant treatment temperature, a movable stopper to support the material, and a cooling container. The design allows for the raw magnet powder to be fed into the furnace, where it undergoes hydrogen heat treatment. After treatment, the stopper opens, allowing the processed magnet powder to fall into the cooling room. This continuous process significantly enhances production efficiency and the quality of the processed magnet powder.
Another patent focuses on a production method and apparatus for HDDR (hydrogenation, disproportionation, desorption, and recombination) treatment. This invention addresses the challenges of maintaining a constant temperature during the treatment due to exothermic and endothermic reactions with hydrogen. By utilizing dummy material, the apparatus compensates for heat fluctuations, ensuring temperature control within a desired range. This method allows for mass production of anisotropic rare earth magnet powder while maximizing the material's properties.
