Title: Hirofumi Shimura: Innovator in Carbon Allotropes and Optical Mirrors
Introduction
Hirofumi Shimura is a notable inventor based in Tsukuba, Japan. He has made significant contributions to the fields of materials science and optical engineering. With a total of 3 patents, his work focuses on innovative methods for producing carbon allotropes and advanced optical mirrors.
Latest Patents
One of Shimura's latest patents is a method for producing carbon allotropes. This method involves forming a coating film of a carbon allotrope on a substrate by continuously supplying fine carbon powder while simultaneously irradiating it with a high-output laser beam. This process induces sublimation of the carbon powder, which is then quenched to deposit on the substrate. Another significant patent is for an optical mirror that features a carbon-composite substrate with an intermediate layer. In this design, a mirror surface formation material, such as aluminum, is coated on a c/c composite substrate, which is then ultrahigh precision machined to minimize deformation.
