  • Patent number: 10706808
    Abstract: Provided is a video signal line driver circuit capable of displaying a video with a high viewing quality even when gradation voltages of the same value are simultaneously selected as analog video signals. A voltage ladder 87 of a source driver 50 has formed therein gradation voltage supplement lines 91 extending to the outside of the source driver 50 from output terminals for outputting generated gradation voltages. The gradation voltage supplement lines 91 are grounded outside the source driver 50 via voltage supplement capacitors 90. Accordingly, even when gradation voltages of the same value are simultaneously selected as analog video signals, the voltage supplement capacitors 90 provide necessary current supplement to the voltage ladder 87, thereby inhibiting potential drop across the output terminals for outputting gradation voltages.

  • Patent number: 8279375
    Abstract: In one embodiment of the present invention, a liquid crystal apparatus includes first and second transmissive liquid crystal panels which are combined with each other. Each of the liquid crystal panels displays a video image in accordance with an identical video source. The first liquid crystal panel is driven by an interlace method in which a video image corresponding to one frame is displayed in two fields while the second liquid crystal panel is driven by a progressive method in which a video image corresponding to one frame is displayed in one field. Accordingly, the display apparatus has high display quality and no interference fringes. This attains a liquid crystal display apparatus with high display quality since the liquid crystal display apparatus has no interference fringes even if a plurality of transmissive liquid crystal display panels are combined with each other.

  • Patent number: 7942648
    Abstract: Lifetime required of mobile-use fuel cells is secured and prolonged, stabilized pump performance is maintained by preventing bearing seizure and abnormal wear. The shaft (101) of a pump mechanism section (100) and the shaft (201) of a motor section (200) are integrated, and the shafts (101, 201) are supported by two or more ball bearings disposed in the pump mechanism section (100), thereby making it possible to fill grease in the closed spaces of the ball bearings (300), and secure a sufficient lifetime basically with almost no possibility of the grease leaking out, even if it is used at a relatively high environmental temperature.

  • Patent number: 7632084
    Abstract: It is an object of the present invention to provide a vane rotary type air pump in which a pump mechanism and a drive motor are directly connected to each other and low noise is realized. In the vane rotary type air pump in which a cylinder (103), a rotor (110 ) and a vane (112) are sandwiched between a front plate (not shown) and a rear plate (not shown), an opened end (111b) of the vane groove (111) is provided in a reversed rotation direction region of the rotor (110) with respect to straight line connecting a center O of the rotor (110) and the closed end (111a) of the vane groove (111). That is, a “stroke” type vane disposition is employed. With this noise of the air pump is reduced.

  • Patent number: 7522127
    Abstract: Out of two display pixels connected to the same gate line G2, a display pixel (A) is connected to a source line S2, and a display pixel (B) is connected to a source line S3, which is adjacent to the source line S2 and forms a parasitic capacitance with a pixel electrode of the display pixel (A). A write signal for a display pixel (A) is obtained by correcting an input signal for the display pixel (A) in accordance with an input signal for a display pixel (B) or a write signal for the display pixel (B). With this arrangement, it is possible to reduce crosstalk between the two display pixels in a display device, such as a liquid crystal display device, that drives display pixels through a plurality of source lines and a plurality of gate lines.
