Latest Patents

Tsutomu Cho holds a patent for an invention titled "Amorphous Cut Core." This invention pertains to a core made of magnetic amorphous alloy. The core is created by winding a thin strip of the alloy and then cutting it to form C-shaped pieces. A pair of these C-shaped pieces is assembled to create the core. The invention addresses the issue of impaired magnetic properties at the cut ends of the strip, which are typically affected by the formation of burrs. By ensuring that the cut ends have a thickness similar to the non-cut portion and polishing them parallel to the major surface, the magnetic properties of the core are significantly improved.
