Title: Innovations by Yukihiko Fukushima

Introduction

Yukihiko Fukushima is a notable inventor based in Wako, Japan. He has made significant contributions to the field of hydraulic control systems, particularly in vehicular transmission technologies. With a total of 2 patents to his name, his work has had a considerable impact on automotive engineering.

Latest Patents

Fukushima's latest patents include a hydraulic controller for transmission and a vehicular transmission control system. The hydraulic controller comprises a first hydraulic control valve mounted on an end face of a first housing unit, along with an oil pump and an input shaft of a transmission. The oil pump features an outer rotor and an inner rotor within a pump casing, which is mounted on the valve body of the first hydraulic control valve. This innovative design allows the input shaft to rotate and drive the inner rotor, effectively sucking oil from the bottom of the transmission housing and supplying it through the mounted part into the first hydraulic control valve.

The vehicular transmission control system patent addresses the adjustment of currents supplied to electromagnetic valves when the engine rotational speed falls below a reference speed. This system generates a second biasing force in each electromagnetic valve to compensate for the decrease in a third biasing force caused by back pressure in the oil passages. This innovative approach enhances the efficiency and reliability of vehicular transmission systems.
