    摘要: Disclosed is an ink jet recording apparatus and an ink jet head which ejects an ink droplet from an ink chamber via an orifice in response to transformation of a piezoelectric member. The ink jet head has a non-piezoelectric member having a groove; a film provided on the non-piezoelectric member to cover the groove, a space formed between the groove and the film being used as the ink chamber; and a piezoelectric member provided on the film corresponding to the ink room. The piezoelectric member has a plurality of surfaces one of which is fixedly connected with the film corresponding to the ink room and other of which are facing to air.

    摘要: A piezo-electric actuator is rigidly mounted for a portion of one surface and provided with opposing electrodes for application of a bias. Because the mounted portion is constrained from deformation, the piezo-electric actuator deforms in a bending manner upon application of a bias. The actuator is provided with a mirror surface for selective reflection of an incident light beam in accordance with a bending deformation of the actuator. The actuator can also modulate a light beam by selectably deflecting into the light path to thereby block the light beam.

    摘要: The present invention relates to an ink jet recording apparatus using an electrostatic actuator. The present invention provides an ink jet recording apparatus comprising a resilient oscillating plate that is facing a pressure chamber that communicates with a nozzle, a first electrode provided on said oscillating plate, a second electrode opposing said first electrode across a space, and a voltage application unit that applies across the first electrode and the second electrode a first voltage that causes the ink in said pressure chamber to be ejected and a second voltage that does not cause the ink to be ejected, wherein said second voltage is applied a specified time prior to the application of the first voltage, so that the residual electrical charges on the first electrode and/or the second electrode can be positively discharged.

    摘要: An ink jet head for a printer wherein an ink drop is ejected from a nozzle to fly and land on the recording paper to form an image. The ink jet head includes the nozzle for ejecting ink, an ink channel that communicates with the nozzle, a pair of oscillating plates that are opposing to each other on walls of the ink channel, a pair of electrodes disposed in contact with the oscillating plates, an ink chamber for holding the ink, and an inlet for supplying the ink from the ink chamber to the ink channel. A gap between the electrodes is filled with the ink having a relative dielectric constant higher than air. A voltage is applied between the electrodes.
