摘要：
An actuator is sequentially charged with output voltage “E/2” of a voltage source and output voltage “E” of a voltage source. After the charging, “Q/2” of electric charge “Q” stored in the actuator is discharged on a path returning to the voltage source. Subsequent to the discharging, the remaining all electric charge “Q/2” stored in the actuator is discharged on a closed circuit.
