Driving circuit for vibration type actuator apparatus










Image Number 17 for United States Patent #6229402.

A pulse forming circuit for a vibration type actuator apparatus. This circuit forms pulses by shifting an output from a frequency dividing circuit while changing the shift amount of a time delaying circuit using a ring oscillator for shifting an output from the frequency dividing circuit every time an output is generated by a frequency dividing circuit. With this arrangement, the actuator can be driven by using high-resolution pulse signals.
