Title: Ink jet head and method for joining its constituting member
Inventor: HIWADA SHUHEI
IPC: B41J2/055
Filed: 2001-11-19
Abstract: PROBLEM TO BE SOLVED: To provide an ink jet head which can stably print by diffusing heat generated by a driver IC 2 and reducing temperature irregularities generated to an actuator plate 7. SOLUTION: The thermal conductivity of an alumina substrate 1 as a ceramic based substrate is high as compared with a combined thermal conductivity of the actuator plate 7 and a cavity plate 10, and therefore the heat generated at the driver IC 2 is easy to diffuse and radiate at the alumina substrate 1. When a heating value of the driver IC 2 increases to conduct the heat to the actuator plate 7, the heat diffused at the alumina substrate 1 is conducted through the whole of a joining face, so that a local temperature rise of the actuator plate 7 is avoided. Effects by temperatures of all jet energy generating elements are made uniform. A stable printing output can be obtained by controlling printing according to a temperature change based on a detected value of a thermistor 4.
