    摘要： An ink jet recording head for ejecting ink drops by expanding or shrinking a pressure generation chamber of an ink flow route forming member consisting of nozzle openings, the pressure generation chamber, an ink supply port, and a reservoir. Piezoelectric vibrators are disposed and fixed in a row with a predetermined pitch, to a piezoelectric vibrator support plate having excellent cutting properties and the piezoelectric vibrator support plate is fixed to a base made of material having a larger rigidity than the support plate. If the piezoelectric vibrator support plate receives reaction forces when ink is ejected, the base having a larger rigidity than the support plate resists the reaction force and suppresses undesired displacement of the contiguous piezoelectric vibrators.

    摘要： The present invention provides a technique which, in a display device, can easily realize the inversion of an image displayed on a display panel in the lateral direction as well as in the vertical direction without requiring an external switching part for changing over a start pulse, the changeover of a signal and the like. In a display device which includes a plurality of pixels and drive circuits which drive the plurality of pixels, each drive circuit includes a first input/output terminal, a second input/output terminal, a scanning-direction changeover terminal, and a position designation terminal, in response to a voltage applied to the position designation terminal and a scanning-direction control signal applied to the scanning-direction changeover terminal, the scanning direction is switchable between the first scanning direction which acquires a start pulse from the first input/output terminal and outputs the start pulse from the second input/output terminal and the second scanning direction which acquires the start pulse from the second input/output terminal and outputs the start pulse from the first input/output terminal.

    摘要： An electrostatic latent image is formed on an image carrier. A first roller is opposed to the image carrier with a gap in between. A second roller is in contact with the first roller such that toner of a one-component type is supplied onto the image carrier by way of the first roller to develop the electrostatic latent image as a visible toner image. A single power source supplies a bias voltage in which an AC voltage is superposed on a DC bias voltage. The bias voltage is supplied to the first roller through a first path and to the second roller through a second path. A resistor is provided on the first path between the first roller and a branching point of the first path and the second path.
