摘要： When recovering power from a motor driver, a forward voltage across a parasitic diode can reduce the recovery efficiency, and control of a power recovery operation can take an unnecessarily long time. In order to address this problem, the power recovery operation is performed as follows without being affected by a parasitic diode: near a peak position of a waveform of an induced current resulting from free oscillation of a rotor after a drive pulse is output, a recovery pulse having such a level that the rotor does not rotate is output from a terminal different from a motor driver terminal to which the drive pulse was output. Also, by adjusting the width and output timing of the recovery pulse based on a power supply voltage, the power recovery can be optimized for the power supply voltage.

The radio correcting timepiece comprises a signal receiving means (1) for receiving a standard radio wave and a timepiece means (2) for correcting and displaying time on the basis of the time information outputted from the signal receiving means. The signal receiving means (1) can receive plural standard radio waves and includes memory means (1I) which is able to store signal receiving order of the plural standard radio waves. Since the plural standard radio waves can be received, the influence of a radio wave situation according to an area can be reduced and a correction to the exact time can be made in a shorter time by using the standard radio wave transmitted every minute.
