    摘要: A voltage detection circuit detects a voltage of a secondary cell that powers a stepping motor. A rotation detection circuit detects a rotation state of the stepping motor, and a control unit selects a main driving pulse for driving the stepping motor based on the detected rotation state from plural kinds of driving pulses having different energies. An analog display unit announces that the voltage of the secondary cell becomes a predetermined reference voltage when the voltage detection circuit detects that the voltage of the secondary cell becomes the predetermined reference voltage. When the control unit selects a predetermined main driving pulse before the voltage detection circuit detects that the voltage of the secondary cell becomes a current reference voltage, the control unit sets the reference voltage to the predetermined reference voltage higher than the current reference voltage.

    摘要: A motor drive device includes a charging detection and reverse current prevention portion and a pulse selection control portion. The charging detection and reverse current prevention portion detects a charging state of a secondary battery that is charged by an electromotive force of a solar battery, the charging state indicating whether the secondary battery is being charged. The pulse selection control portion causes a first drive pulse for driving a motor to be generated and, in a case where the charging state that is detected by the charging detection and reverse current prevention portion is different after the first drive pulse has been output from what it was before the first drive pulse was output, causes a second drive pulse for driving the motor to be generated.

    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 wristwatch with an oscillation alarm uses an ultrasonic motor as its drive source. A vibration member has a piezoelectric element adhered thereto on one side and comb-like projections on the other side. A rotor has a sliding member composed of resin at its contacting portion with the comb-like projections and an eccentric weight at its outer circumferential portion. Shock absorbers are sandwiched between the weight and the rotor to absorb shocks applied to the rotor and thus prevent rotor damage. In the vicinity of the upper or lower side of the weight, there is disposed an abutment portion made of rigid material, the abutment portion abutting with the weight when shocks of large magnitude are applied to the rotor to assist the shock absorbers in preventing damage to the rotor.

    摘要: A power generation unit generates electric power depending on light to be irradiated to a light receiving surface. An electricity storage unit stores the electric power generated by the power generation unit and outputs the stored electric power. A voltage detection unit detects a voltage of the electric power that is output from the electricity storage unit. A processing unit performs time measurement. A chronograph indicator points a time counted by the processing unit and is fixed by a mechanism while the time measurement is stopped. A second driving circuit drives the chronograph indicator by the use of the electric power that is output from the electricity storage unit. The processing unit drives the second driving circuit when the voltage of the electric power which is output from the electricity storage unit is equal to or greater than a predetermined threshold value.
