Title: Naoto Oji: Innovator in Sintered Magnet Technology
Introduction
Naoto Oji is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of materials science, particularly in the development of advanced sintered magnets and dielectric ceramic materials. With a total of 2 patents, Oji continues to push the boundaries of innovation in his field.
Latest Patents
Oji's latest patents include a sintered magnet and a method for producing the sintered magnet. This invention aims to ensure the strength of a thin-walled sintered magnet, which is a ferrite sintered magnet made by sintering a magnetic material. The process involves mixing magnetic powder with a binder resin, which is then injection-molded into a mold under a magnetic field. The molded body is subsequently sintered to produce the final product. The sintered magnet boasts a thickness of 3.5 mm or less at its center of gravity and a surface roughness Rz of 0.1 μm or more and 2.5 μm or less.
Another notable patent involves a non-reductive dielectric ceramic material. This material has a main component represented by [(Ca.sub.X Sr.sub.1-X)O].sub.m [(Ti.sub.Y Zr.sub.1-Y)O.sub.2], with specific parameters for X, Y, and m. It also includes auxiliary components that enhance its properties. When used in laminated ceramic condensers, this material can be sintered at temperatures not exceeding 1,300°C, demonstrating a small temperature coefficient of capacitance and a long accelerated lifetime of insulating resistance.
