Title: Yasuhiro Akune: Innovator in Diffraction Gratings and Composite Materials
Introduction
Yasuhiro Akune is a notable inventor based in Hyogo, Japan. He has made significant contributions to the field of materials science, particularly in the development of advanced diffraction gratings and composite materials. With a total of 2 patents, his work showcases innovative approaches to enhancing the efficiency and precision of optical devices.
Latest Patents
One of Akune's latest patents is focused on diffraction gratings. This invention discloses diffraction gratings that do not generate any thermal strain and can perform extremely high-precision and high-efficiency diffraction nearly free from scattered beams. The gratings are constructed by allowing a chemically deposited film of silicon carbide, whose crystal planes are strongly oriented to the (220) planes in terms of Miller indices, to form on a substrate made of sintered silicon carbide. The surface of the deposited film is polished to 5 Å RMS or less, and laminar-type grating grooves are directly etched on that surface using ion-beam etching.
Another significant patent involves a composite material with a chemically vapor deposited layer of silicon carbide. This composite material is designed for use as a construction material for high energy density beam reflectors and other applications. It comprises a substrate and a chemically vapor deposited layer of silicon carbide formed thereon, with the crystal faces in the layer oriented to the (220) plane as indicated by Miller indices.
