Title: Yasuhiro Hirooka: Innovator in Electroplating Technology

Introduction

Yasuhiro Hirooka is a notable inventor based in Chiba, Japan. He has made significant contributions to the field of electroplating technology. His innovative approach has led to the development of a unique counter flow device that enhances the efficiency of plating processes.

Latest Patents

Hirooka holds a patent for a "Counter flow device for electroplating apparatus." This invention features a rotary drum that is partially immersed in a plating solution within a plating bath. A metallic strip, which is to be plated, passes in synchronism with the rotation of the drum. The device includes anodes that are spaced apart from the strip, allowing electric current to flow between them. The counter flow device comprises a bottom nozzle that directs flow opposite to the entering direction of the strip and a top nozzle that ensures uniform counter flows. This design remarkably increases critical current density in plating, resulting in uniform plating.
