Title: Hironari Mitarai: Innovator in Field Magnet Manufacturing
Introduction
Hironari Mitarai is a prominent inventor based in Tokai, Japan, known for his significant contributions to the field of magnet manufacturing. With a total of 14 patents to his name, Mitarai has developed innovative methods that enhance the accuracy and efficiency of manufacturing processes in this specialized area.
Latest Patents
One of Mitarai's latest patents is a method for manufacturing field magnets. This method involves a bonded magnet's inner surface being press-fitted into a yoke with a specific accuracy, regardless of the yoke's outer circumferential surface accuracy. The process utilizes a cylindrical bonded magnet created by binding magnet particles with a thermosetting resin, which is then fixed within a tubular yoke made of magnetic material. The method includes reheating and softening the bonded magnet after thermal curing, followed by a press-fitting process that allows for a relative posture variation between the bonded magnet and the yoke. This innovative approach ensures that the bonded magnet's inner surface is remolded to closely match the yoke's inner surface, achieving high precision in the final product.
