Title: Shigemitsu Tomita: Innovator in Damper Technology

Introduction

Shigemitsu Tomita is a notable inventor based in Yokosuka, Japan. He has made significant contributions to the field of damper technology, holding a total of 7 patents. His innovative designs have enhanced the functionality and efficiency of dampers used in various applications.

Latest Patents

One of his latest patents involves a damper that includes a piston provided with a rod and a housing that stores the piston. This damper generates a braking force through the operation of the piston. The design features a seal member that interacts with the inner wall of the housing, and a slider that contacts this wall with a predetermined frictional force. When the braking force is generated, the slider presses against the seal member, causing a portion of it to deform outward. Additionally, a deformation control portion is integrated to prevent the seal member from deforming inward.

Another recent patent describes a damper that consists of a piston and a cylinder that stores the piston. This design also generates a braking force through the movement of the piston. The cylinder is characterized by width-side wall portions and thickness-side wall portions, with a flat cross-sectional shape in a direction orthogonal to the piston’s movement. The cylinder features a connection portion on its open side, bridging the width-side wall portions.
