摘要:
A display device includes a plurality of light emitting elements arranged in a matrix. A scan signal is made to flow into a gate signal line and a data signal is made to flow into a source signal line so that the data signal is applied to a source electrode and the scan signal is supplied to a gate electrode of a control TFT arranged at a portion where the both signal lines intersect when viewed from above. Thus, when the control TFT is turned ON, a drive TFT having a gate electrode connected to the drain electrode is turned ON, so that current is supplied from a power supply line via the source electrode and the drain electrode of the drive TFT to an organic EL element and the organic EL element emits light. A holding capacity is present between the control TFT and the drive TFT. Even when the scan signal becomes LOW level and the control TFT turns OFF, the gate potential of the drive TFT is held for a predetermined period of time by the holding capacity and the organic EL element continues to emit light.

摘要:
The invention is directed to a throttle control apparatus for controlling an opening of a throttle valve in an internal combustion engine, in response to operation of an accelerator operating mechanism. The apparatus includes a motor, a clutch, and a control circuit which controls the clutch to selectively take one of a first position of the motor engaged with the throttle valve and a second position disengaged therefrom. There is provided a first detector for producing a first signal corresponding to an amount of operation of the accelerator operating mechanism. Also provided is a second detector for producing a second signal corresponding to an opening angle of the throttle valve. Independent of the control unit, it is determined in accordance with the first and second signals if there is an abnormality, in which the throttle valve opens at an angle more than a predetermined angle when the accelerator operating mechanism is positioned at its initial position. When the abnormality continues for more than a predetermined time period, a signal indicative of the abnormality will be produced, and the clutch will be caused to disengage the motor from the throttle valve. When the signal indicative of the abnormality is continuously produced after the clutch disengages the motor from the throttle valve, the supply of fuel to the engine will be cut off.

An element is provided which operates in two selectable mode. The element converts the analog output of a knock sensor to a digital value in one mode and compares the analog output with the reference value in the other mode. The average output of the knock sensor is calculated from the digital value and the reference is calculated from the average output. In the occurrence of any knocking, the output of the knock sensor is greater than the reference.
摘要:
A method for detecting knocking in internal combustion engine, wherein a plurality of constants K is stored corresponding to a plurality of ranges of engine speed. A reference value is calculated from a means value of an output signal of a knock sensor, from the constant K corresponding to an engine speed and from a predetermined offset value, through a calculation of multiplying the mean value by the constant K and adding the offset value to the result of the multiplication. Then an output signal, newly provided from the knock sensor after the calculation of the mean value, is compared with the reference value so as to decide that knocking occurs in the engine when the newly given output signal of the knock sensor exceeds the reference value. Therefore, the reference value can be suitably determined corresponding to the engine speed so that a detectable lower limit of knocking intensity is kept to be substantially constant.
