Title: Hiromasa Hayashi: Innovator in Metal Processing Technologies

Introduction

Hiromasa Hayashi is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of metal processing, holding a total of 4 patents. His innovative approaches have led to advancements in manufacturing techniques, particularly in the removal of adhesive materials and the production of power-module substrates.

Latest Patents

One of Hayashi's latest patents is a method of cutting and removing adhesive matter at the end of cuboid metal material. This invention ensures that adhesive matter is reliably removed in a relatively short time while minimizing the decrease in yield rate of the metal material. The process involves measuring the distances of the upper and lower surfaces of the cuboid metal material from a reference position. Based on these measurements, the state of the remaining adhesive matter is assessed, allowing for precise cutting by a cutting tool.

Another significant patent is the manufacturing method of power-module substrates. This method involves bonding copper-circuit plates on a ceramic plate and subsequently dividing the ceramic plate between the copper-circuit plates. The process includes forming bonding-material layers of active-metal brazing material and temporarily fixing the components using a temporal-stick material. The laminated assembly is then pressurized and heated to achieve a strong bond between the ceramic plate and the copper-circuit plates.
