Title: The Innovations of Susumu Yaba
Introduction
Susumu Yaba is a prominent inventor based in Yokohama, Japan. He has made significant contributions to the field of materials science, particularly in the development of quartz glass substrates and transparent quartz glass products. With a total of 7 patents to his name, Yaba's work has had a lasting impact on various technological applications.
Latest Patents
Yaba's latest patents include a "Quartz glass substrate for polysilicon thin film transistor liquid" and "Transparent quartz glass and process for its production." The quartz glass substrate is designed for use in polysilicon thin film transistor liquid crystal displays, featuring a halogen content of no more than 10 ppm, an OH content of no more than 100 ppm, and a total content of heavy and alkali metal elements not exceeding 1 ppm. The annealing point of this substrate is set at a minimum of 1,150 degrees Celsius. The transparent quartz glass is produced by flame-hydrolyzing a glass-forming raw material to create fine quartz glass particles, which are then deposited and grown on a substrate. This process results in a porous quartz glass product that is subsequently heated to yield a transparent quartz glass product with an OH content of no more than 10 ppm and a halogen content of at least 400 ppm.
