Abstract:
According to one embodiment, an ink jet head includes an actuator configured to cause ink to be discharged from a pressure chamber associated with the actuator, and a control unit configured to apply to the actuator in a droplet ejection process an auxiliary signal that does not cause ink to be discharged from the pressure chamber, and a discharge signal that causes ink to be discharged from the pressure chamber.

Claim (Index 15):
An ink jet head, comprising:\n a first piezoelectric plate attached to an upper surface of a substrate; a second piezoelectric plate attached to an upper surface of the first piezoelectric plate, wherein the first and second piezoelectric plates have polarizations opposite to each other along a direction parallel to thicknesses of the first and second piezoelectric plates; a chamber comprising:\n a groove cut from an upper surface of the second piezoelectric plate toward a bottom surface of the first piezoelectric plate, shielded by a top plate at the upper surface of the second piezoelectric plate and by an orifice plate at a front edge of the groove; \n an electrode on inner walls of the groove; and \n a nozzle in the orifice plate at the front edge of the groove; \n a pattern generator that generates an auxiliary signal and a discharge signal; a drive circuit configured to receive the auxiliary signal and the discharge signal and drive the chamber, wherein\n the auxiliary signal does not cause ink to be discharged from the pressure chamber, and \n the discharge signal that causes ink to be discharged from the pressure chamber.
