    摘要： Disclosed is a chronograph timepiece whose chronograph hands are electrically drive-controlled and mechanically zero-restoring-controlled, wherein it possible to perform a normal operation at the time of start operation and reset operation. After a mechanical control unit releases the setting of chronograph hands in response to the start operation of a start/stop button, a contact portion is placed in a start state, and an electrical control unit starts a time measurement operation to electrically hand-movement-drive the chronograph hands, and, after a contact portion is placed in a reset state in response to a reset operation of a reset button and the electrical control unit electrically resets the time measurement operation, the mechanical control unit mechanically zero-restores and sets the chronograph hands.

    摘要： A stepping motor control circuit includes a rotation detecting means which detects an induced signal generated by rotation of a rotor of a stepping motor, and detects a rotation state of the stepping motor according to whether the induced signal exceeds a predetermined reference threshold voltage in a predetermined detection section, and a control means which controls driving of the stepping motor by using any one of a plurality of main driving pulses having energies different from each other or a correction driving pulse with energy higher than energy of each main driving pulse according to a detection result of the rotation detecting means. The detection section is divided into a first section immediately after driving by the main driving pulse, a second section after the first section and a third section after the second section. During the driving of the stepping motor by the main driving pulse, when the rotation detecting means has detected an induced signal exceeding a first reference threshold voltage in the first section and the second section, if an induced signal exceeding a second reference threshold voltage lower than the first reference threshold voltage is not detected in the third section, the control means drives the stepping motor by using the correction driving pulse.

    摘要： A phase locked loop (PLL) circuit is provided to operate in a broad band, including two separate loops one of which is for feed-back of an output from an oscillator to the same oscillator through its associative proportional control unit and the other of which is for feed-back of an output of an oscillator to the same oscillator via an integral control unit. The proportional control unit is arranged to control an output frequency of the oscillator and is operable to generate a control signal based on a difference between input and output signals. The integral control unit is arranged to control the phase of an output signal of the oscillator to thereby generate a control signal based on a phase difference between input and output signals.
