Title: Innovations by Katsutoshi Miyakawa
Introduction
Katsutoshi Miyakawa is a notable inventor based in Kyoto, Japan. He has made significant contributions to the field of thermoplastic resin technology. With a total of 3 patents to his name, his work has had a considerable impact on the industry.
Latest Patents
Miyakawa's latest patents include a method of producing thermoplastic resin films and an apparatus for producing the same. This innovative method allows for the formation of a biaxially oriented polyester film at a high speed of 400 m/min or more. The process involves bringing a molten thermoplastic resin film into contact with a cooling medium, which cools and solidifies the film to produce a cast film. The method is characterized by maintaining the surface temperature of the cooling medium at a level that is not lower than the glass transition temperature and not higher than the melting point of the thermoplastic resin. The apparatus features a cooling medium equipped with both a heater and a cooler to ensure the requisite temperature is maintained.
Another significant patent is the polyester film reflector for a surface light source. This reflector comprises a white polyester film with fine voids, resulting in an apparent specific gravity ranging from 0.5 to 1.2. The fine voids enhance the reflectance of the polyester film, making it ideal for use in surface light sources with a side light system, such as liquid crystal displays, providing a bright and easily visible scope.
