Abstract: An electronic apparatus 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 selects an operation mode of the electronic apparatus based on different reference values selected based on whether the first power feeder is feeding power to the secondary battery or the second power feeder is feeding power to the secondary battery.

Abstract: Disclosed is a stepping motor including a rotor, a plurality of coils and a switching mechanism. The stepping motor simultaneously or sequentially applies driving pulses to the coils to rotate the rotor by a predetermined step angle, and while the driving pulses are being applied to part of the coils, the switching mechanism switches the rest of the coils other than the part of the coils driven by the driving pulses into a high impedance state.

Abstract: An electronic apparatus 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 detects a voltage of the secondary battery, and determines a remaining power of the secondary battery based on a comparison of the detected voltage with first or second reference values. The first reference value is a predetermined value set in accordance with the current fed by the first power feeder. The second reference value is a predetermined value set in accordance with the current fed by the second power feeder, and is higher than the first reference value.

Abstract: An embodiment of an electronic timepiece includes a cylindrical exterior case, a bezel and a windshield member. In the exterior case, a circuit board is housed. The bezel is formed of a metal material to be ring-shaped, includes an inward flange part that projects from an inner side surface toward a center of the ring-shaped bezel, is arranged on an outer upper side of the exterior case and is electrically connected with the circuit board. The windshield member is formed of a transparent dielectric substance, arranged in the bezel and supported by the inward flange part. The bezel is configured to resonate with a radio wave having a desired frequency by adjustment of at least one of (i) a relative permittivity of the dielectric substance and (ii) an area of an overlap region where the inward flange part and the windshield member overlap each other.

Abstract: An electronic apparatus includes a first power feeder, a positioning-satellite-signal receiver, and a CPU. The first power feeder receives power from an external device and feeds the power to a secondary battery. The positioning-satellite-signal receiver receives a satellite signal transmitted by a positioning satellite. The CPU limits a receiving operation of the positioning-satellite-signal receiver when the first power feeder is receiving the power from the external device.
