Title: Hiroaki Happou: Innovator in Vibration-Damping Technology

Introduction

Hiroaki Happou is a notable inventor based in Komaki, Japan. He has made significant contributions to the field of vibration-damping technology, holding a total of 2 patents that showcase his innovative designs and engineering expertise.

Latest Patents

Hiroaki Happou's latest patents include a fluid-filled type vibration-damping device. This device features an elastic body that connects a first and second mounting member while sealing off one opening of the second mounting member. It also incorporates a flexible film that fluid-tightly seals off another opening of the second mounting member. A partition member is firmly fitted into the second mounting member, forming a pressure-receiving chamber and an equilibrium chamber that communicate via an orifice passage. Additionally, a short circuit passage connects the two chambers, with a valve body that allows for communication based on the elastic deformation of the elastic body when excessive pressure differentials arise.

Another patent by Happou is also a fluid-filled type vibration-damping device. This design includes a main rubber elastic body that elastically connects first and second mounting members. A partition member supported by the second mounting member creates a pressure-receiving chamber filled with a non-compressible fluid and an equilibrium chamber defined by a flexible film. The chambers are formed on either side of the partition member, allowing fluid communication through an orifice passage. A short-circuit passage enables the two chambers to be short-circuited, and a valve is used to switch the short-circuit passage, with a metal spring holding the valve in a closed state at a predetermined level of elastic deformation.
