Title: Shin-ichi Nishi and Inkjet Recording Head Innovation.

Introduction

Shin-ichi Nishi is an inventor associated with Hachioji, Japan, and Konica Corporation. His patent work includes an inkjet recording head designed to eject ink through channels actuated by a piezoelectric element.

Latest Patents

The provided information identifies one patent for Nishi: “Inkjet Recording Head.” The invention describes an actuator substrate made from polarized piezoelectric material, with grooves forming partition walls between multiple ink channels. A cover plate attached to the partition walls forms the channels’ top surfaces, while a nozzle plate at the front of the substrate provides openings for ejecting ink.

The patent specifies a machinable-ceramic cover plate with greater thermal conductivity than the piezoelectric element. It also sets a limit on the difference between the cover plate’s and piezoelectric element’s linear thermal expansion coefficients, and includes a top plate with greater thermal conductivity than the cover plate. Nishi is credited with 1 patent in the information provided.
