の制御回路。[Claims for Utility Model Registration] (1) A first signal generating means for forming a control signal by time-sharing a signal at a frequency that can be tracked mechanically by a solenoid actuator according to an input signal;
a second signal generating means for generating a drive signal for energizing the solenoid of the solenoid-type actuator by forming an electrical time-division signal with a signal of a sufficiently higher frequency than the signal of the frequency based on the control signal; A control circuit for a solenoid type actuator, characterized by comprising: (2) The control signal includes a first control signal that commands a large starting current to the solenoid for a short period of time when the solenoid starts energizing, and a first control signal that is continuous with the first control signal and 2. A control circuit for a solenoid type actuator according to claim 1, characterized in that the control circuit is formed by a second control signal that commands a holding current of the solenoid to be smaller than that of the second control signal. (3) The drive signal is a pulse train formed by a pulse signal having a duty ratio corresponding to the magnitude of the first control signal and a pulse signal having a duty ratio corresponding to the magnitude of the second control signal. Scope of claim 1 for utility model registration characterized by being a signal
A control circuit for a solenoid actuator according to item 1 or 2.
