Shigenobu Nishida

Introduction

Shigenobu Nishida, based in Komaki, Japan, is an accomplished inventor known for his significant contributions to solenoid valve technology. He holds three patents that showcase his innovation in developing efficient and effective solutions for fluid control systems.

Latest Patents

One of Nishida's notable patents is the "Solenoid Valve with 2-Part Fixed Core." This innovative solenoid valve is designed to handle corrosive control fluids while enhancing the attraction force. The design features a fixed core positioned within a wound coil, extending through the lower surface of the coil. A plunger, supported by a plate spring beneath the fixed core, operates a valve sheet that normally remains in contact with a valve seat due to the spring force. Upon energizing the coil, the valve sheet separates from the valve seat, allowing for fluid control. The fixed core is ingeniously comprised of two vertically coupled parts: a first fixed core made of a highly permeable material located in non-contact with the control fluid, and a second fixed core made of a corrosion-resistant material that fits within the coil bobbin, ensuring functionality in high-corrosive environments.

Another patent attributed to Nishida is the "Gas Supply Unit." This innovative unit comprises a base member equipped with multiple fluid control devices connected through a series of passage blocks. The passage blocks facilitate fluid communication and include an inlet port, an outlet port, and a filter cavity that ensures clean fluid management.
