Title: Eiji Furuya: Innovator in Plasma Technology

Introduction

Eiji Furuya is a notable inventor based in Kishiwada, Japan. He has made significant contributions to the field of plasma technology, holding a total of 2 patents. His work focuses on developing advanced apparatuses for plasma generation and vacuum coating.

Latest Patents

Furuya's latest patents include a plasma generation apparatus and a vacuum coating forming device. The plasma generation apparatus is designed to generate uniform plasma over a wide range. It features two oppositely arranged plasma guns that inject a discharge gas for ionization. Each gun has a cathode for emitting electrons and a converging coil to form a magnetic flux that guides the emitted electrons. Notably, the polarities of the converging coils with respect to the cathodes in the two plasma guns are opposite to each other.

The vacuum coating forming device is intended for creating a thin-film coating by a plasma beam on a substrate within a vacuum chamber. This device includes a pressure gradient type plasma gun that generates the plasma beam directed toward the vacuum chamber. Additionally, it has a converging coil that surrounds a short-tube portion of the vacuum chamber, reducing the cross-section of the plasma beam. An insulating tube is provided at the outlet to surround the plasma beam, and an electron return electrode is positioned within the short-tube portion, maintaining a higher electric potential than the outlet.
