Title: The Innovative Contributions of Masato Sawada
Introduction
Masato Sawada is a notable inventor based in Kanagawa-ken, Japan. He has made significant contributions to the field of technology, particularly in the development of thermal heads and light-emitting devices. With a total of 3 patents to his name, Sawada's work exemplifies innovation and technical expertise.
Latest Patents
One of Sawada's latest patents is a method for manufacturing a thermal head. This method involves forming a resistance heating element and an electrode on an insulating substrate. The resistance heating element emits heat through a current, while the electrode connects to it. The process includes forming a corrosion prevention layer on the heating element and electrode, followed by annealing the heating element and adjusting its electrical resistance. Finally, a protective layer is formed on the corrosion prevention layer, with glass as a main component. Notably, the annealing occurs before the adjustment, and the corrosion prevention layer is formed prior to annealing.
Another significant patent is for a light-emitting device that features a composition modulation layer of unequal amounts of at least two elements. This device includes a light-emitting layer, an n-type contact layer made of a compound, and a transparent electrode. The composition modulation layer consists of multiple elements, with one element having a higher composition ratio than in the compound. Alternatively, the device may include a metal layer with a lower work function than the compound, positioned between the n-type contact layer and the transparent electrode.
