Title: The Innovative Contributions of Shinji Sugihara

Introduction

Shinji Sugihara is a notable inventor based in Mizuho, Japan. He has made significant contributions to the field of engineering, particularly in the development of solenoid valve control devices and relief valve devices. With a total of 6 patents to his name, Sugihara's work has had a considerable impact on various applications in the industry.

Latest Patents

One of Sugihara's latest patents is the solenoid valve control device and solenoid valve control method. This invention features an internal pressure sensor that detects the internal pressure of a fuel tank, which stores fuel. The solenoid valve is designed to close to seal the fuel tank and open to allow access to the fuel. An internal pressure acquisition unit is responsible for acquiring the internal pressure from the sensor. The drive control unit then controls the solenoid valve to open when the internal pressure is greater than or equal to a first predetermined value, which is a negative value, and less than a second predetermined value, which is zero or a positive value.

Another significant patent is the relief valve device. In this device, a positive-pressure relief valve opens a first valve port when the pressure in a pressure chamber increases to a level that meets or exceeds the positive-pressure side valve-opening pressure. Conversely, a negative-pressure relief valve opens a second valve port when the pressure decreases to a level that meets or falls below the negative-pressure side valve-opening pressure. The device includes a positive valve-opening pressure adjustment unit that adjusts the set load of a positive-pressure spring based on the amount of an adjustment screw screwed into the pedestal plate. Similarly, a negative valve-opening pressure adjustment unit adjusts the set load of the negative-pressure spring through the valve plate by moving the pedestal plate relative to the housing main body.
