Title: Osamu Yamashita: Innovator in Tire Inspection and Magnetic Technology
Introduction
Osamu Yamashita is a prominent inventor based in Osaka, Japan, known for his significant contributions to the fields of tire inspection technology and magnetic materials. With a total of 16 patents to his name, Yamashita has made remarkable advancements that have impacted various industries.
Latest Patents
Yamashita's latest patents include a method and apparatus for inspecting pneumatic tires during production. This innovative inspection method involves measuring the displacement amount in a radial direction on each of the beads lying axially on both sides of the tire building drum. By utilizing a distance sensor, such as an eddy current sensor, while rotating the drum, the method synthesizes the displacement amounts obtained on the beads and calculates a harmonic of these amounts through harmonic analysis. This process allows for determining whether the magnitude of the calculated harmonic falls within a predetermined range, ensuring quality control in tire production.
Another notable patent is for an anisotropic thin-film rare-earth permanent magnet. This invention features a vapor-phase-grown thin film that is rendered anisotropic in the layering direction, resulting in high magnetic characteristics. The atomic laminate units are formed by laminating a monoatomic layer of a rare earth element on a substrate of a non-magnetic material, followed by the layering of a transition metal element. This construction suppresses inverse magnetic domains and establishes a strong coercive force, significantly improving the residual magnetic flux density.
Career Highlights
Throughout his career, Osamu Yamashita has worked with esteemed companies such as Sumitomo Special Metals Co., Ltd. and Neomax Co., Ltd.
