Latest Patents

Kainuma holds a patent for a "Method of manufacturing electromagnetic members." This patent discloses a technique for creating an electromagnetic member that possesses both magnetic anisotropy and electrical conductivity. The method involves coating the outer circumferential surface of multiple magnetic strips with a first electrically conductive material to a predetermined thickness, forming composite magnetic strips. These strips are then bound together, and the spaces among them are filled with a second electrically conductive material similar to the first. This approach allows for the production of a mechanically strong electromagnetic member, where the ratio of magnetic to electrical properties can be easily adjusted by varying the thickness of the conductive material, while also preventing the formation of blow-holes.
