  • Patent number: 8866700
    Abstract: A first cabinet comprising a first display module and a second cabinet comprising a second display module are provided. A switching is allowed between: a first state in which the first cabinet is placed on top of the second display module and the first display module faces outside, and a second state in which the first cabinet and the second cabinet are arranged next to each other and the first display module and the second display module face outside. A first screen to be displayed by the first display module and a second screen to be displayed by the second display module are stored and a screen switching operation is detected. Displaying of the first screen on the first display module is canceled and the second screen is displayed on the first display module, when the screen switching operation is detected in the first state.

  • Patent number: 8838364
    Abstract: A control device of a spark-ignition gasoline engine is provided. The control device includes a controller for operating the engine body by controlling at least a fuel injection valve, an ignition plug, and a fuel pressure variable mechanism. Depending on the engine load range, the controller sets the combustion mode to a compression-ignition mode or a spark-ignition mode. In each mode, the controller also controls the fuel pressure, and the timing of fuel injection and ignition. The controller may also performs external EGR control in each mode.

  • Publication number: 20140126264
    Abstract: An entry including multiple bits of unit cells each storing data bit is coupled to a match line. The match line is supplied with a charging current having a restricted current value smaller than a match line current flowing in a one-bit miss state in one entry, but larger than a match line current flowing in an all-bit match state in one entry. A precharge voltage level of a match line is restricted to a voltage level of half a power supply voltage or smaller. Power consumption in a search cycle of a content addressable memory can be reduced, and a search operation speed can be increased.

  • Patent number: 8706382
    Abstract: The disclosure provides a control device of a spark-ignition gasoline engine. When an operating state of an engine body is within a low engine speed range, a controller controls a fuel pressure variable mechanism so that a fuel pressure is higher within a high engine load range compared to a low engine load range, the controller operates, within the high engine load range, a fuel injection valve to perform a fuel injection at least at a timing that is more retarded than an injection timing of a fuel within the low engine load range and is within a retard period from a late stage of a compression stroke to an early stage of an expansion stroke, and the controller operates, within the high engine load range, an ignition plug to ignite at a timing within the retard period and further after the fuel injection.

  • Patent number: 8441828
    Abstract: The present invention provides a content addressable memory capable of higher frequency operation than conventional. When a search enable signal supplied from a search control circuit is asserted, each of search line drivers transfers search data to each CAM cell of a CAM memory array via a search line pair. The search line enable signal is transmitted to the search line drivers via a single control signal line coupled to the search control circuit. The control signal line is coupled to the search line drivers in such a manner that the search line enable signal passes through coupling nodes between the search line drivers and the control signal line in an arrangement order of the search line drivers from the side far away as viewed from match amplifiers.

  • Publication number: 20120234942
    Abstract: A spray gun (1) forms a desired spray pattern by atomizing by means of atomizing air (A) a spray liquid which is sprayed from a liquid ejection port (44) opened/closed by a needle valve (4), and jetting pattern air (P) to the flow of spray mist of the atomized spray liquid. A nozzle taper angle (?1) is set in a range of 5° to 15°, and a cap taper angle (?2) is set in a range of 20° to 40°. Atomizing air (A) is jetted from a nozzle insertion hole (58) toward the center of a nozzle (3). Pattern air (P) is jetted in a spreading suppressed region (R) wherein the flow of the spray mist does not spread over an area greater than or equal to a predetermined cross-sectional area, to the flow of spray mist, and as a result, the spray mist is more uniformly sprayed over a wide range.
