Hidehiko Katoh is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of thermal printing technology. With a total of 4 patents, his work has been instrumental in enhancing printing quality while reducing costs.
Latest Patents
One of his latest patents is an integrated thermal printing head and method of manufacturing the same. This invention features a thermal printing head that utilizes a heating resistor prepared through a thin-film technique, combined with a wiring circuit created using a thick-film technique. This innovative approach achieves high printing quality at a low cost. The thin-film resistor is formed on a heat-insulating dielectric layer, which is partially placed on a dielectric substrate. Thick-film lead electrodes, connected to a driving circuit, are formed on the dielectric substrate to contact the edge of the heat-insulating dielectric layer. Additionally, thin-film lead electrodes connect the thick-film lead electrodes to the ends of the thin-film resistor. The combination of thick-film techniques, such as screen-printing and firing processes, along with thin-film techniques like sputtering or vacuum-evaporating, showcases the advanced manufacturing methods employed in his inventions.
