With a total of 4 patents to his name, Honshima's work has garnered attention for its innovative approaches and practical applications.
Latest Patents
Honshima's latest patents focus on the design and manufacturing methods of Nd based sintered magnets. One of his key inventions involves a sintered Nd base magnet segment that exhibits a coercive force that is high at the periphery and lower toward the inside. The method for preparing this magnet includes several steps: first, providing a sintered Nd base magnet block with defined surfaces and a magnetization direction. Next, the surfaces of the magnet block, excluding the surface perpendicular to the magnetization direction, are coated with a Dy or Tb oxide powder, a Dy or Tb fluoride powder, or a Dy or Tb-containing alloy powder. The coated block is then treated at high temperatures to allow Dy or Tb to diffuse into the block. Finally, the block is cut in a plane perpendicular to the magnetization direction, resulting in a magnet segment with a specific coercive force distribution.
