Title: Innovations of Toshiyuki Fujimura

Introduction

Toshiyuki Fujimura is a notable inventor based in Obu, Japan. He has made significant contributions to the field of fuel cell technology and flow control systems. With a total of 2 patents to his name, Fujimura continues to push the boundaries of innovation in his industry.

Latest Patents

Fujimura's latest patents include a fuel cell system that utilizes an eccentric valve as an inlet sealing valve. This valve features a rubber seat designed to enhance the surface pressure at the contact point with the valve element when the pressure in the air supply passage increases. Additionally, the system incorporates an outlet integration valve and a bypass valve, both of which are structurally similar to the inlet sealing valve. This design allows for efficient control of air supply to a fuel cell stack, particularly during vehicle deceleration.

Another significant patent is the full-close abnormality diagnosis apparatus for a flow control valve. This invention includes an EGR valve with a valve seat in a housing flow passage, a valve element that can seat on the valve seat, and a rotary shaft for opening or closing the valve element. The system is equipped with a motor, a speed-reducing mechanism, and a return spring that urges the valve element to close. An electronic control unit (ECU) is responsible for diagnosing any abnormalities caused by foreign matter lodged between the valve seat and the valve element during the full closure process.
