    • An ink jet printer is provided with an ink jet head. The ink jet head comprises an ink passage body and an actuator. The ink passage body comprises a nozzle, an ink chamber communicating with the nozzle, and a pressure chamber located between the nozzle and the ink chamber. The actuator comprises a piezoelectric element facing the pressure chamber. The piezoelectric element comprises a piezoelectric layer, a first electrode connected with a front face of the piezoelectric layer, a second electrode connected with a back face of the piezoelectric layer, and a first insulator located between the second electrode and the ink passage body. The ink jet printer further comprises a device for maintaining the electric potentials of the ink passage body and the second electrode such that the electric potential of the ink passage body is equal to or below the electric potential of the second electrode.

    • The liquid crystal driving circuit device has AC generating means (50) for generating an alternating current component of a drive signal, a capacitive element (3) with one terminal connected with said AC generating means, current limitation means (2) with one terminal connected with the other terminal of the capacitive element (3), and DC generating means (52, 53), for generating a direct current component of the drive signal, said DC generating means having an output connected to another terminal of the current limitation means (2). The capacitive element (3) eliminates the direct current component of an output signal from the AC generating means (50), and the current limitation means (2) limits a current caused by a voltage difference between a voltage at the other terminal of the capacitive element (3) and a voltage at the output. Further, an amplitude value of the alternating current component from the AC generating means and an amplitude of the alternating current component of a signal from the DC generating means (52, 53) are approximately the same.
