Title: The Innovations of Koji Teranishi

Introduction

Koji Teranishi is a prominent inventor based in Kanagawa, Japan. He has made significant contributions to the field of optical elements, holding a total of 11 patents. His work focuses on advanced methods for producing optical element forming molds and enhancing the quality of optical thin films.

Latest Patents

One of Teranishi's latest patents is a method of producing an optical element forming mold. This innovative method involves forming a ta-C film on a mold matrix for an optical element forming mold through an FCVA process. The mold matrix is maintained at a floating potential, and a voltage is applied to a mold matrix-holding member via insulating members. Additionally, a magnet within the mold matrix creates a magnetic field that applies a magnetic force in the normal direction of the transfer surface, ensuring the film quality is homogenized.

Another notable patent is related to a reactive sputtering method. In this apparatus, an inert-gas supplying hole is integrated into a movable target unit, allowing for the controlled supply of a reactive gas containing fluorine or oxygen. This setup enables the reactive gas to be emitted toward the substrate, maintaining a higher concentration on the substrate surface. The design ensures that even when the target is moved, the concentration of the reactive gas remains constant, facilitating the formation of high-quality optical thin films.
