摘要： A timepiece includes a mechanical movement with a mechanical oscillator and an electronic device for regulating the medium frequency of this mechanical oscillator. It includes an electromagnetic transducer and an electric converter which includes a primary storage unit for powering the regulation circuit. The electromagnetic transducer is arranged to supply a voltage signal exhibiting first voltage lobes in first half-alternations and second voltage lobes in second half-alternations of the oscillations of the mechanical oscillator. The regulating device includes a load pump arranged to transfer electric loads from the primary storage unit into a secondary storage unit, these electric loads being extracted selectively in different time zones according to a time drift detected in the functioning of the mechanical oscillator relative to an auxiliary oscillator, particularly quartz-based.

摘要： An electronic timepiece includes a secondary battery, a first power feeder, a second power feeder, and a processor. The first power feeder feeds power to the secondary battery. The second power feeder feeds power to the secondary battery at a current larger than a current fed by the first power feeder. The processor determines remaining power of the secondary battery based on different references that are a reference of when the first power feeder is feeding the power to the secondary battery and a reference of when the second power feeder is feeding the power to the secondary battery.

摘要： An electronic timepiece includes: a power source; a correlation computation unit executing correlation computation processing of sequentially computing a correlation value between a signal sample and a plurality of codes corresponding to a plurality of satellites; a power source voltage determination unit to which a voltage of a power source is inputted and which determines whether the inputted voltage is lower than a first threshold or not, or whether the voltage exceeds a second threshold set to be equal to or higher than the first threshold; and a correlation computation control unit controlling the correlation computation unit to interrupt the correlation computation processing when the power source voltage determination unit determines that the voltage is lower than the first threshold, and to resume the correlation computation processing when the power source voltage determination unit determines that the voltage exceeds the second threshold.

摘要： Provided are an electronic circuit and electronic timepiece that can initialize internal circuits even if chattering occurs when a battery is installed. In the electronic circuit, when the initialization state hold signal is input, the initialization control circuit continues outputting the initialization control signal at the first level until the clock signal is output; and when the initialization state hold signal is input and the clock signal is output, outputs the initialization control signal at the second level cancelling the initialization process to the initialization circuit.

摘要： An electronic timepiece includes a solar power source, a voltage stabilizer circuit that generates a constant voltage by using power supplied from the solar power source, and a control circuit that clocks the time by driving a rotating body at first hand operation speed and at second hand operation speed which is faster than the first hand operation speed. The control circuit selects a voltage of the solar power source so as to drive the rotating body in a case of the first hand operation speed, and selects at least any one voltage of the constant voltage and the voltage of the solar power source so as to drive the rotating body in a case of the second hand operation speed.

摘要： A power supply unit has a first power supply circuit that supplies a voltage to a load driving unit and a second power supply circuit that supplies a voltage to circuits other than the load driving unit. A first switching unit connects any one of a power supply that supplies a power supply voltage and a voltage step-down circuit that supplies a step-down voltage of the power supply voltage to the first power supply circuit. A second switching unit connects any one of the power supply and the voltage step-down circuit to the second power supply circuit. A control unit controls the connection by the first switching unit and the connection by the second switching unit to switch the voltage supplied to the first power supply circuit and the voltage supplied to the second power supply circuit in accordance with properties of the load driving unit.
