摘要： A liquid crystal controller is provided for a liquid crystal panel having a plurality of pixels, each of which includes a memory element and a display element. The memory element is configured to hold electric potential depending on an image signal and is configured to change the held electric potential based on activation of an enable signal. The display element is configured to be applied voltage depending on the electric potential which the memory element holds. The liquid crystal controller is configured to: hold off outputting the enable signal, for a period th before polarity of AC voltage applied to the display element is inverted and a period (tr+ts) after the polarity of the AC voltage is inverted; and hold off inversion of the polarity of the AC voltage, for an output period of the enable signal and the period th after the output period.

摘要： A motor drive device includes a driver unit configured to be connected to a stepping motor, and a controller connected to the driver unit. The controller causes the driver unit to output a drive pulse to the stepping motor for causing the stepping motor to rotate stepwise in a prescribed rotation direction. The controller detects, through the driver unit, a current induced by a counter-electromotive force generated in the stepping motor in response to the drive pulse. The controller causes the driver unit to apply a counter pulse having the same electrical polarity as the drive pulse to the stepping motor so as to suppress an amount of the current induced by the counter-electromotive force when the stepping motor is not rotating in response to the drive pulse so that the amount of the induced current detectably differs between when the stepping motor is rotating and not rotating.

摘要： 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.

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 device includes: a memory configured to a program; and one or more processors configured to execute the program stored in the memory. The one or more processors are connected to a first circuit and a second circuit, the first circuit being configured to execute a first operation cyclically and output an interrupt signal corresponding to the first operation, the second circuit being configured to execute a second operation in response to an operation instruction. In response to receiving the interrupt signal, the one or more processors output the operation instruction to the second circuit such that the second operation is not executed in a period in which the first operation affects the second operation.

摘要： 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.
