ABSTRACT:
A color apparatus includes an electroexpansive actuator, a unit for supplying a charge to the electroexpansive actuator, and a unit for controlling an amount of charge discharged from the electroexpansive actuator, and a stroke of the electroexpansive actuator is controlled in accordance with the amount of charge discharged therefrom. When such an electroexpansive actuator is applied to a control apparatus for a fuel injection valve, a fuel injection amount per ON/OFF operation of the fuel injection valve or a fuel injection rate can be freely controlled.
