    摘要： A shock absorber system for controlling the damping forces of shock absorbers comprising a drive apparatus for operating a piezo-actuator which is constructed by laminating a plurality of piezoelectric elements. The drive apparatus comprises a high-voltage generation circuit for generating a high voltage and a charging and discharging circuit for applying the high voltage, generated by the high-voltage generation circuit, to the piezo-actuator and for discharging an electric charge charged in the piezo-actuator due to the application of the high voltage thereto, the charging and discharging results in expansion and contraction of the piezo-actuator. Also included in the drive apparatus is an abnormality detection circuit for detecting a charging current or a discharging current passing through a charging or discharging current passage coupled to the piezo-actuator at the time of charging or discharging by the charging and discharging circuit. The abnormality detection circuit determines an abnormality of the drive apparatus when the detected charging current or discharging current is below a predetermined value.

    摘要： A control system for an internal combustion engine wherein the torque developed by an internal combustion engine is detected to provide optimum control of the ignition timing of the engine and thereby to ensure an improved engine efficiency as well as an improved fuel economy. The system comprises an engine torque detector for detecting the torque developed by the engine, a signal generator for generating signals used to periodically change the ignition timing of the engine, a phase discriminator for discriminating the phase relation between the output signals of the engine torque detector and the periodic change signal generator, and ignition timing control means for controlling the ignition timing in response to the output of the phase discriminator.
