摘要： An electronic timepiece including a stepping motor and a time-indicating hand moved in a stepwise manner by the stepping motor for indicating time. During normal operation the time-indicating hand moves at a normal periodic rate. When operating conditions such as a low battery cause the stepping motor to not rotate, correcting pulses are applied to the stepping motor to supply additional energy to it to cause it to rotate. Additionally, the correcting pulses cause the rotor, and the time-indicating hand to rotate at a rate different from the normal periodic rate to alert the timepiece user that some condition exists tending to cause non-rotation of the stepping motor.

摘要： An electronic timepiece circuit including a data memory for storing time information and display information, and an operating circuit which renews the data stored in the data memory circuit. A program memory circuit stores a sequential program for determining generation of control signals supplied to the data memory circuit and the operating circuit. Two different command data systems are stored in the program memory circuit. One command data system consists of controlling commands which carry out time counting, time setting and display functions, and for pointing addresses in the data memory circuit. The other command data system consists of commands for judging conditions, for pointing addresses of the data memory and for pointing the jump address of the programs stored in the program memory circuit.

摘要： In an electronic timepiece having a stepping motor, a drive pulse is produced for normally driving the motor, a detecting pulse is generated for detecting whether the motor has rotated in response to the last drive pulse and a correction pulse is produced for driving the motor when non-rotation has been detected. A current limiting resistor is disposed in series with the motor for limiting the current thereto and a switching transistor is connected across the current limiting resistor to short circuit same to effect an increase in the current to the motor. During the detecting pulse, the voltage across the current limiting resistor is compared to a predetermined value. If the voltage is above the predetermined value, which indicates that the motor has not rotated in response to the last drive pulse, the switching means is actuated to short circuit the current limiting resistor and the correction pulse is applied to the motor during the resulting increased current condition so that the motor will be enabled to rotate even when a higher torque load is applied thereto. In this way, a decreased amount of current is used during the normal torque loading condition on the motor.

摘要： An electronic timepiece reduces power consumption by normally driving the stepping motor with a short pulse and driving the motor with a wide pulse under heavy load conditions by sensing the rotor position. A detection circuit senses the voltage drop across a detection element in series with the motor coil for driving a first detection pulse and senses again for driving a second detection pulse. If the second voltage drop is larger, then the rotor is not rotating whereupon the wide pulse is used to drive the motor.

摘要： A level shift circuit comprises an inverter connected to a first voltage supply source and supplied with an input pulse. A condenser and a directional switching element are connected in series between the output point of the inverter and one potential point of the first voltage supply source. The input of a first MOS-FET is connected to the output of the inverter while the input of a second MOS-FET is connected to a connection point between the condenser and the directional switching element. The source of the first MOS-FET is connected to a common terminal of first and second voltage supply sources while the source of the second MOS-FET is connected to the other terminal of the second voltage supply source. An output voltage is generated between a common connecting point of the drains of the first and second MOS-FETs and one potential point of the second voltage supply source.
