  • Publication number: 20160086543
    Abstract: A flash phenomenon of OLEDs at the time of power source ON of a display device is suppressed. The OLED emits light when reference potentials VSS and VDD are applied from power source lines to the OLED's cathode and anode respectively. While the anode can be connected to one of the power source line via a driving TFT and a lighting switch, a reset potential VRS can be applied to the anode via a reset switch and the driving TFT. The lighting switch is turned OFF and the reset switch and the driving TFT are turned ON so that VRS is applied to the anode, before starting the application of the reference potentials to the power source lines. Following this state, the application of the reference potentials to the power source lines starts, and thus a normal operation of allowing the OLED to emit light starts.

  • Patent number: 9048888
    Abstract: A power line communication system is provided in which the influence of the impulsive noise unexpectedly generated on a power line which is a communication medium can be reduced according to the characteristics of the impulsive noise by an existing method and power line communication can be realized without a hindrance. A transmitter is constituted by: a modulator for conveying a LIN data signal by a power line; a filter that allows a signal of a predetermined band to pass therethrough; and a sinusoidal wave outputter (sinusoidal wave in the figure). In contrast, the receiver is constituted by the sinusoidal wave outputter, the filter and a demodulator that performs demodulation. To the power line, a limiter that limits the amplitude of the propagating signal to a predetermined amplitude (reception signal amplitude) is connected.

  • Patent number: 8579764
    Abstract: A control apparatus for an idle-stop system mounted on a manual-transmission-vehicle includes a restart unit performing a restart operation of the engine such that the restart unit drives a starter to restart the engine when a predetermined restart condition is met. The restart condition includes a condition where a clutch member is operated to allow the motive force to be transmitted between the output shaft of the engine and the driving wheel of the vehicle while the motive force has been blocked by the clutch, and a condition where the brake member is operated to stop applying the braking force to the wheel while the motive force has been blocked by the clutch. A forced stopping means is adapted to stop the wheels by forcibly applying the braking force to the wheels by operating a brake actuator during a predetermined period since the restart condition is met.

  • Patent number: 8556774
    Abstract: A device for controlling an automatic start of the engine mounted on a vehicle which includes a clutch to transmit/block motive power between an output shaft of the engine and the driving wheel of the vehicle. The automatic start control device includes an automatic restart processing in which a starter is driven to crank the engine when predetermined restart conditions are met thereby restarting the engine. The automatic start control device detects a state of the clutch being either transmitting or blocking and detects whether or not a transition of the state occurs during the cranking of the engine in the automatic restart processing. The control device forcibly stops driving of the starter when the transition of the state occurs.

  • Publication number: 20130238225
    Abstract: An engine control apparatus is provided for controlling an engine of a motor vehicle. The engine control apparatus is configured to automatically stop the engine by stopping combustion in the engine when a predetermined automatic stop condition is satisfied and restart the engine by driving a starter when a predetermined restart condition is satisfied. The engine control apparatus includes a calculator and a condition changer. The calculator calculates an accumulated value by accumulating a starter deterioration-related value each time the engine is started or restarted by the starter; the accumulated value is indicative of the degree of deterioration of the starter. The condition changer changes, when the accumulated value has increased to reach a threshold value, the predetermined automatic stop condition so as to lower the frequency of the engine being automatically stopped and restarted and thereby suppress deterioration of the starter.
