Title: Innovations by Mitsushi Maeyama in Supercharger Rotor Manufacturing

Introduction

Mitsushi Maeyama is a notable inventor based in Chiba, Japan. He has made significant contributions to the field of manufacturing, particularly in the design and production of supercharger rotors. With a total of 2 patents to his name, Maeyama's work showcases his expertise and innovative approach to engineering.

Latest Patents

Maeyama's latest patents focus on a method and apparatus for manufacturing supercharger rotors. The first patent describes a method that involves casting a profile portion of a supercharger rotor along with a shaft that penetrates it. The process includes cutting a left and right helical cross portion on the surface of the shaft, which features both right-handed and left-handed helical grooves that intersect. This is followed by casting the profile portion around the shaft using die-casting techniques. The design allows for a plurality of profile portion divided metal molds to surround the rotor, ensuring precision and efficiency in manufacturing.

The second patent elaborates on a similar method, emphasizing the use of divided metal molds that surround the profile portion of the rotor. This design includes a pair of end metal molds that encapsulate both ends of the rotor. A helical core is attached to one end mold, allowing it to be helically passed through the rotor's profile portion. The process involves pressurizing hot metal, injecting it into the cavity formed by the molds, and solidifying it. The end metal mold with the helical core is then extracted by rotating it along a helical line, ensuring a seamless manufacturing process.
