Latest Patents

Horikawa's latest patents include innovations in thermal print heads and thermal printers. One of his patents aims to provide a thermal print head capable of improving printing quality on a medium. The solution involves a base member that includes a recess, a heat storage region formed in the recess, a resistor layer formed on the base member, and an electrode layer that is electrically connected to the resistor layer. The resistor layer features a heating portion that spans between two portions of the electrode layer, which are spaced from each other in the thickness direction of the base member. The heating portion is strategically located to overlap the recess, ensuring optimal performance. The base member is constructed from a material with a thermal conductivity of 100 to 300 W/(m·K).

Another patent focuses on a thermal print head and its manufacturing method. This design includes a substrate, a resistor layer, an electrode layer, and an insulating layer. The electrode layer consists of a first electrically conductive portion and a second electrically conductive portion that are spaced apart. The resistor layer features a heater portion that bridges these two conductive portions. The insulating layer is positioned between the electrode layer and the heater portion, which helps reduce the formation of a eutectic region between them.
