Title: The Innovations of Yoshiharu Honjo
Introduction
Yoshiharu Honjo is a prominent inventor based in Kanagawa, Japan. He has made significant contributions to the field of optical technology, particularly through his innovative patents. With a total of 2 patents, Honjo continues to push the boundaries of what is possible in his area of expertise.
Latest Patents
Honjo's latest patents include an antireflection film and a manufacturing method thereof. This antireflection film is designed to be applied to the surface of a glass panel of a CRT. It can be manufactured inexpensively while maintaining high productivity. The film meets all necessary requirements regarding adhesive strength, reflectance characteristics, electric resistance, and total light transmittance. The structure of the film involves stacking silicon oxide films and indium tin oxide films on a base film in multiple layers. Notably, the thickness of the uppermost silicon oxide film is greater than that of the indium tin oxide film directly beneath it. Additionally, the lowermost silicon oxide film, which interfaces with the base film, is a SiO film where the value x ranges from 0.5 to 1.9.
Another significant patent is for a black roll used for optical measurement. This device is essential for the process of moving a film substrate around the black roll while measuring the optical characteristics of a thin film formed on the substrate. The black roll features a rotating black-colored cylinder with grooves designed to absorb light emitted from an optical monitor. This innovation effectively eliminates almost all reflectance of light from the black roll during measurements.
