Title: Shigeo Hashimoto: Innovator in Magnetic Field Technology
Introduction
Shigeo Hashimoto is a prominent inventor based in Saga, Japan, known for his significant contributions to magnetic field technology. With a total of 13 patents to his name, he has made remarkable advancements in the field, particularly in applications related to magnetic resonance imaging (MRI).
Latest Patents
One of Hashimoto's latest patents is a magnetic field generator for MRI. This innovative device is designed to be applicable to various magnetic field generators and effectively prevents the separation of permanent magnets that constitute permanent magnet groups. The generator includes a pair of permanent magnet groups, each consisting of multiple bonded permanent magnets, which are positioned opposite each other with a space in between. The design features projections that extend outward beyond the area of contact with the respective pole pieces, and a flange-shaped member is attached to each outer circumferential surface of the pole pieces, covering the space-facing surface of the projection.
Another notable patent is a recycling method for magnetic field generators. This method involves a magnetic field generator that comprises a pair of plate yokes connected by a column yoke. Each plate yoke has opposed surfaces equipped with permanent magnets, including a plurality of neodymium magnets. The method entails demagnetizing the neodymium magnets and grinding adhesive while heating the generator to temperatures between 200°C and 350°C. After demagnetization, the adhesive is removed, and the neodymium magnets are collected for reuse. The process also includes carbonizing the adhesive at higher temperatures, allowing for the polishing and re-aging of the collected neodymium magnets for further use.
