Latest Patents

Miyawaki holds a patent for a "Permanent magnet production method." This method involves inserting a mandrel into a through hole formed in an extrusion die. A preform is filled in the through hole and extruded into a filling space defined between the inner surface of the through hole and the outer surface of the mandrel by pressing the preform with a pressing punch. This process results in a cylindrical extruded form with multiple stress concentration portions that are spaced apart in the circumferential direction. An external force is then applied to divide the extruded form at these stress concentration portions into several permanent magnets. He has 1 patent to his name.
