Latest Patents

Her latest patents demonstrate her ingenuity and technical expertise. One of her notable inventions is a method for manufacturing a permanent magnet that incorporates a Dysprosium (Dy) and Terbium (Tb) film on the surface of an iron-boron-rare earth sintered magnet. This design enhances the coercive force of the magnet, making it more efficient. The method involves a film-forming step, where metal evaporating material containing Dy and Tb is evaporated and adhered to the magnet's surface. A subsequent heat treatment step allows for the diffusion of these metal atoms into the grain boundary phases of the magnet, improving its overall performance.

Another key invention is a vacuum evaporating apparatus designed to create a metal vapor atmosphere within a processing chamber. This apparatus facilitates the adhesion of metal atoms to the surface of the objects being processed, followed by their diffusion into the grain boundary phases. The innovative design includes a processing furnace, processing boxes, and a heating mechanism that works under reduced pressure to achieve optimal results.
