摘要： In a piezoelectric actuator control device for controlling operation of one or more piezoelectric actuators, when receiving a drive signal of a low level, a discharging switch is repeatedly turned on and off in order to discharge electric charge accumulated in the piezoelectric actuator. That is, the discharging switch is kept ON until a discharging current from a piezoelectric actuator reaches a peak threshold value Ip. When the discharging current reaches the peak threshold value Ip, the discharging switch is turned OFF and kept OFF until a discharging current from a piezoelectric actuator reaches a peak threshold value Ip. The device has a threshold value setting circuit for increasing the peak threshold value according to a discharging period of time.

摘要： A fuel injection control apparatus drives piezoelectric actuators for opening and closing injectors of respective cylinders based on energy stored in a capacitor of a DC/DC converter. A current detecting resistor for controlling a boost switch to charge the capacitor is disposed at a position at which current flowing through the capacitor is not detected. Further, current detecting resistors for controlling the piezoelectric actuators are disposed at positions at which charging current from a diode to the capacitor is not detected. Thus, the charging of the capacitor can be performed even during the control for charging/discharging the piezoelectric actuator.

摘要： A power supply voltage booster avoids inadequate step-up capability. In a voltage boosting circuit, a switching device connects and disconnects between the ground potential and one end of the coil, the other end of which is supplied with a supply voltage VB. The switching device is repeatedly turned ON and OFF such that the capacitor is electrically charged from the force in the coil when the switching device is turned off. A charging control circuit turns off the switching device when current flowing through the switching device into the coil is determined to have increased to a switch-off threshold value when the switching device is ON, and turns on the switching device upon determining that the charging current flowing to the capacitor from the coil decreases to a switch-on threshold value when the switching device is OFF. The charging control circuit sets the switch-off threshold value to a larger value as the supply voltage VB is lower. Thus, inadequacy of the step-up capability caused by a drop in the supply voltage VB can be avoided.

摘要： A driving device for a piezoelectric actuator supplies charges and discharges the piezoelectric actuator through a charging switch and a discharging switch, respectively. The charging switch is repeatedly turned on and off thereby to charge and expand the piezoelectric actuator. The discharging switch is repeatedly turned on and off thereby to discharge and contract the piezoelectric actuator. The discharging switch is kept ON especially during a period from when the discharging switching control is terminated to when the charging switching control is started next. Thus, the piezoelectric voltage at the start of the next driving can be made substantially 0V.

摘要： An active matrix liquid crystal display apparatus comprises first and second substrates facing each other through a liquid crystal layer. The first substrate has a plurality of scan bus lines, thin film transistors, display electrodes, and reference potential supplying bus lines, and the second substrate has a plurality of stripe-like data bus lines that face the display electrodes. The display electrode has a compensation capacitor for compensating a potential fluctuation occurring in the display electrode after a gate electrode of the thin film transistor is selected. The capacitance of the compensation capacitor is larger during a compensation period than during a storage period in which the gate electrode of the corresponding thin film transistor is not selected.
