Latest Patents

Matsuo holds a patent for a thin-film thermal print head and the method of producing it. This invention features a resistor layer formed over an insulative substrate, with a conductor layer that has a specified planar pattern overlapping the resistor layer. A portion of the resistor layer serves as a heat-emitting part, which is not covered by the conductor layer. Additionally, a protective layer is formed over the heat-emitting part and at least a portion of the conductor layer adjacent to it. This protective layer may be a conductive layer with resistance greater than that of the heat-emitting part, allowing static electricity generated by friction with printing paper to escape quickly to the conductor layer. The protective layer may also include a wear-resisting layer, enhancing the durability of the print head.
