Title: Minoru Yamamoto: Innovator in Diamond Film Technology
Introduction
Minoru Yamamoto is a distinguished inventor based in Okazaki, Japan. He has made significant contributions to the field of materials science, particularly in the synthesis of high-purity diamond films. With a total of seven patents to his name, Yamamoto's work has advanced the technology used in various industrial applications.
Latest Patents
Yamamoto's latest patents include an "Apparatus for forming diamond film" and a "Method and apparatus for forming a diamond film." The first patent describes a process for synthesizing a diamond film of high purity at a high rate. In this innovative method, a mixture of hydrocarbon gas and hydrogen gas is introduced into an arc discharge to produce a gas plasma. This gas plasma is then directed onto a substrate to deposit diamond. The design includes a third electrode positioned above the substrate, which is connected to a power supply. This configuration allows for the electrical current to promote the decomposition of the gases, resulting in the deposition of high-quality diamond films.
The second patent outlines a method and apparatus that maintains a vacuum within a casing to facilitate diamond film formation. A gas plasma generator creates a gas plasma near the substrate, while a detector monitors the surface temperature of the diamond film. An electronic controller adjusts the temperature to maintain it near an optimal value, ensuring the production of high-purity diamond films regardless of thickness or forming time.
