Title: Innovations of Katsuyoshi Arai

Introduction

Katsuyoshi Arai is a notable inventor based in Wako, Japan. He has made significant contributions to the field of engineering, particularly in the development of innovative mounting and vibration prevention technologies. With a total of 5 patents to his name, Arai's work has had a considerable impact on various applications.

Latest Patents

One of Arai's latest patents is a combination viscous and resilient type of mount. This invention comprises a rigid boss that connects to a moving component, such as a reciprocating engine, and an annular flange that connects to a stationary support. A resilient element, shaped like a frustoconical structure, supports the moving component relative to the stationary support. Additionally, a deformable element works with the resilient element to create a chamber for viscous fluid, while a rigid partition divides the fluid chamber into a working chamber and a compensation chamber. This innovative design allows for effective vibration control.

Another significant patent is a vibration preventing apparatus using fluid. This apparatus features a main and an auxiliary fluid chamber, with fluid confined within. The two chambers communicate through three types of orifices that provide varying degrees of resistance to fluid flow. The main fluid chamber is partly defined by an elastic member that supports a vibrating body. As the vibrating member operates, the volume of the main fluid chamber changes, displacing fluid through the orifices based on the instantaneous vibration. This design effectively absorbs vibrations, enhancing performance.
