    Patent number: 8049848
    Abstract: A liquid crystal display having a wide viewing angle and easily manufactured. The liquid crystal display comprises an upper substrate and a lower substrate, and a liquid crystal material disposed between the upper substrate and the lower substrate. The liquid crystal display has a conductive protrusion disposed on the surface of the upper substrate opposing to the lower substrate. The conductive protrusion is disposed over a scanning electrode line or a signal electrode line and has the same potential as that of the upper electrode. As another structure, each of pixel electrodes on the lower substrate has a smaller area than that of a common electrode on the upper substrate and is covered by the common electrode, and each of the pixel electrodes comprises an electrode portion having approximately symmetrical shape.

  • SLIDING COMPONENT
    Publication number: 20110215531
    Abstract: An aspect of the invention provides a sliding component in which a phase made of liquid and a phase made of gas, which are formed in a sliding portion, are stabilized. A sliding component constitutes one of two sliding components that rotate relatively, and planar end faces of the two sliding component slide on each other. In the sliding component, a plurality of dimples is arrayed in a sliding surface such that, in a phase made of liquid and a phase made of gas, the phase made of the gas is positioned when the two components rotate relatively. The phase made of the liquid and the phase made of the gas are formed so as to revolve about rotation centers of sliding portions of the two components.

  • Control for determining a firing timing of an internal-combustion engine
    Patent number: 7909018
    Abstract: A control for determining a firing timing of an engine is provided. An in-cylinder pressure is detected at a predetermined time interval. An in-cylinder pressure for every predetermined crank angle is calculated based on the detected in-cylinder pressure. A motoring pressure in a case where combustion is not performed in the engine is estimated. It is detected that a pressure difference between the calculated in-cylinder pressure and the motoring pressure has exceeded a determination value. A time point is identified, as a firing timing, at which the pressure difference has exceeded a determination value with a finer resolution than the resolution of the predetermined crank angle interval through an interpolation calculation.
