    摘要: A thermal inkjet printhead is provided including a substrate, and a chamber layer, which is stacked on the substrate. The chamber layer includes an ink chamber that is filled with ink supplied from an ink feed hole. The printhead includes a heater inside the ink chamber that heats the ink, an island, which is formed on the substrate at an ink inlet port of the ink chamber, and a nozzle layer, which is stacked on the chamber layer, including a nozzle for ejecting the ink. The walls of the ink chamber and the island that face each other are symmetrical with respect to the center of the nozzle.

    摘要: An apparatus to sense the temperature of an ink-jet head includes at least one or more CMOS (complementary metal oxide semiconductor) lateral BJTs (bipolar junction transistors) to sense the temperature of the ink-jet head, and a current supply unit to supply a current to the CMOS lateral BJTs. Minimum sized CMOS lateral BJTs are applied to an ink-jet printer head so that precise temperature control can be performed in a shuttle or array type ink-jet printer.
