Introduction

Hikofumi Yamamoto is a notable inventor based in Osaka, Japan. He has made significant contributions to the field of vibration control technology, holding a total of 7 patents. His work focuses on developing innovative solutions that enhance the performance and durability of hydraulic devices.

Latest Patents

Yamamoto's latest patents include a liquid-sealed vibration control device. This device features a hydraulic style that incorporates a lower attachment fitting, which forms an air chamber between a diaphragm and itself. The fitting is made of aluminum and includes a through-hole for a bolt that is press-fitted, ensuring a secure connection without a large projection into the air chamber. This design not only reduces costs but also increases strength by having a thicker bottom wall portion compared to the peripheral wall portion.

Another significant patent is for a hydraulic antivibration device arrangement. This arrangement aims to achieve downsizing and weight reduction while minimizing booming noise. By incorporating a protuberant rubber portion at the upper end of the main body member, the spacing distance from the roll center is lengthened. This innovation diminishes the reaction force to impingement, allowing for a reduction in the rigidity and strength required for the components, ultimately leading to a lightweight hydraulic antivibration device.
