It is another object of the invention to drive load circuits working intermittently in such a way that, the load circuits are driven by energy accumulated in an capacitor during {HEAD ~ inoperative periods} of {TAIL ~ the load circuits} for processing loads which are small enough to allow signal processing to be completed in a short time of the order of several tens of milliseconds
