Title: Kazushi Sasaya: Innovator in Mechanical Engineering
Introduction
Kazushi Sasaya is a notable inventor based in Katsuta, Japan. He has made significant contributions to the field of mechanical engineering, holding a total of 4 patents. His work primarily focuses on innovative joint structures and gas compressors, showcasing his expertise in creating efficient mechanical solutions.
Latest Patents
One of his latest patents is a joint having a ball and shaft coupled through plastic deformation. This joint structure is designed for bonding a ball portion and a shaft portion, with the ball featuring a mounting hole bored toward its center. A corrugated surface is formed in the inner circumferential surface of the mounting hole to enhance the bonding process. The shaft portion, made of a softer material than the ball portion, fits into the mounting hole, where it undergoes local plastic deformation near the corrugated surface, ensuring a strong bond between the two components.
Another significant patent is for a gas compressor, which features a cup-like casing. This innovative design includes a driving shaft that is rotatably carried by the bottom of the casing, with a rotary plate secured to it. The driven shaft is positioned at a 20-degree inclination against the driving shaft and is supported by a bearing on the end of the driving shaft. The cylinder block, fixed to the driven shaft, contains cylinder bores that receive pistons coupled with the rotary plate, allowing for efficient reciprocation of the pistons upon rotation of the driving shaft.
