  • Publication number: 20180108826
    Abstract: The purpose of the present invention is to provide a fibrous piezoelectric element which enables a large electric signal to be drawn out by stress produced by relatively small deformation. A piezoelectric element includes a braid composed of a conductive fiber and a piezoelectric fiber. In the braid, the conductive fiber is a core, and the piezoelectric fiber is a covering fiber that covers the periphery of the conductive fiber.

  • Publication number: 20170282132
    Abstract: An ozone water production device (1) includes: flow rate controllers (4, 5) that each control a flow rate of gas which is a raw material; a flow rate meter (12) that measures a flow rate of water which is a raw material; a booster pump (13) that controls pressure of the water; an ozone water generating unit (8) that generates ozone water by mixing ozone gas and the water; and a pressure sensor (17) that measures pressure of the ozone water which is to be supplied to a use point (19). The booster pump (13) controls the pressure of the water such that the pressure of the ozone water measured by the pressure sensor (17) is constant. The flow rate controllers (4, 5) each control the flow rate of the gas in accordance with the flow rate of the water measured by the flow rate meter (12).

  • Publication number: 20140152878
    Abstract: A solid-state imaging device includes a plurality of color filters, which are composed of a plurality of first color filters and a plurality of second color filters. In plan view: the first color filters and the second color filters are arranged alternatively in each of an X direction and a Y direction, and thus form a checkerboard pattern; and each of the first color filters, at a corner portion thereof, (i) has an oblique side that extends diagonally with respect to the X and Y directions, and (ii) is adjacent to another one of the first color filters that is located diagonally therefrom. Each one of the first color filters is partitioned from another one of the first color filters located diagonally therefrom and adjacent thereto at a corner portion by a shift portion of the barrier wall that extends in parallel with the oblique side.

  • Patent number: 8030193
    Abstract: To fabricate a Schottky barrier diode in which a decrease in on current due to parasitic resistance is suppressed, variations in on current are suppressed, and an increase in off current is suppressed. The fabricating method includes the steps of forming an island-shape semiconductor film; doping the island-shape semiconductor film with a first impurity element to form a first impurity region; forming an insulating film so as to cover the island-shape semiconductor film; etching the insulating film to form a first opening and a second opening that partly expose the first impurity region; forming a mask over the insulating film so as to cover the first opening and expose the second opening; doping the first impurity region with a second impurity element to form a second impurity region; and forming a first wiring in contact with the first impurity region exposed at the first opening, and forming a second wiring in contact with the second impurity region exposed at the second opening.
