Title: Toshiichi Sekine: Innovator in Film Formation Technology
Introduction
Toshiichi Sekine is a prominent inventor based in Kamifukuoka, Japan. He has made significant contributions to the field of film formation technology, holding a total of 13 patents. His work primarily focuses on enhancing the durability and performance of cylindrical members through innovative film application methods.
Latest Patents
One of Sekine's latest patents is a method of forming films over the inner surface of cylindrical members. This invention relates to creating an intermediate film and a hard carbon film on the inner surface of components like bushings or cylinders. The process involves placing the cylindrical member in a vacuum vessel, where an auxiliary electrode is inserted into its bore. By applying a voltage, a plasma is generated, allowing the sputtering of an intermediate film forming material, such as a titanium-silicon alloy. Following this, a gas containing carbon is introduced to form a hard carbon film, significantly improving the abrasion resistance of the inner surface.
Another notable patent involves a jig for forming a hard carbon film over the inner surface of a guide bush. This invention utilizes an auxiliary electrode support member to align the auxiliary electrode with the center bore of the guide bush. The setup allows for the introduction of carbon gas into the vacuum vessel, where plasma is produced to create a durable hard carbon film on the guide bush.
