Title: Hirokazu Ootoshi: Innovator in Electrophotographic Technology
Introduction
Hirokazu Ootoshi is a prominent inventor based in Nagahama, Japan. He has made significant contributions to the field of electrophotographic technology, holding a total of 2 patents. His work focuses on improving the durability and performance of light-receiving members and thin-film transistors.
Latest Patents
Ootoshi's latest patents include an electrophotographic light-receiving member that features a substrate and a photoconductive layer composed of a non-single crystal material. This layer contains silicon atoms and a surface layer made of silicon, carbon, and hydrogen atoms. The innovative design ensures that at least 50% of the silicon atoms in the surface layer have at least one bond to a carbon atom, resulting in excellent initial electrophotographic properties and enhanced durability in high-humidity environments.
Another notable patent is a method for making a thin-film transistor using a concentric inlet. This improved thin-film transistor includes a principal semiconducting layer made from an amorphous material. The process involves introducing gaseous substances into a film-forming chamber and chemically reacting them in the absence of plasma to generate various precursors, which are then used to form the layer on the substrate.
