摘要： An electronic apparatus having a generator that generates electric power, a storage unit in which electric energy generated by the generator is stored, and a motor driven by the electric energy stored in the storage unit, wherein it is judged whether or not a magnetic field is generated by the power generation. If the magnetic field is judged to occur, it is judged that, when a correcting driving-pulse signal having an effective power level higher than that of an ordinary driving-pulse signal outputted for motor control is outputted to the motor, the magnetic field is generated when the storage unit is charged.

摘要： A multifunctional electronic watch of the present invention displays data measured by a built in atmospheric pressure sensor (56) by means of a small atmospheric pressure pointer (10) and an atmospheric pressure pointer (11). It is also capable of displaying a differential between the present atmospheric pressure and an atmospheric pressure three hours before by means of an atmospheric pressure tendency pointer (21). A dial ring (17) attached around a clockface of the watch is formed with an atmospheric pressure scale (18). The watch further comprises a battery (74) and a control IC (40). The IC (40), the sensor (56) and the battery (74) are positioned so that they are deviated with one another on a plane. The built in sensor is accommodated in the watch so as not to project from the rotation bezel of the watch. Accordingly, an electronic watch which has additional functions of indicating environmental data such as atmospheric pressure and is thin can be realized.

摘要： Convex and concave structures formed in an end portion 22b of a stator yoke 22 and an end portion 23b of a magnetic core 23 are mated in a staggered manner and are joined. An upper projecting portion 22b-1 of the stator yoke 22 is fitted in a recessed portion formed on a lower projecting portion 23b-2 of the magnetic core 23, and the lower projecting portion 23b-2 of the magnetic core 23 is fitted in a recessed portion formed under the upper projecting portion 22b-1 of the stator yoke 22. In this state, the stator yoke 22 and the magnetic core 23 are fixedly fastened by a joint screw 24 and a tube 26. This structure makes it possible to reduce magnetic resistance in a magnetic circuit structure and to improve power-generating efficiency of a power-generating device using the structure.

摘要： In an electronic apparatus which includes a power generator for performing power generation, a storage device for storing electric energy obtained by the power generation, a motor driven by the electric energy stored in the storage device, and a pulse driving controller for controlling the driving of the motor by outputting a driving pulse signal, it is detected whether the motor is rotating by comparing the rotation detecting voltage which is proportional to the induction voltage generated in the motor caused by the rotation of the motor with the rotation reference voltage. The generation state of the power generator or the charging state of the storage device is detected. The voltage level of the rotation detecting voltage or the voltage level of the rotation reference voltage is shifted by a predetermined amount based on the detected generation state of the power generator or the detected charging state of the storage device so that the voltage difference between the rotation detecting voltage and the rotation reference voltage is increased during the no-rotation period.

摘要： An electronic timepiece charging device for charging an electronic timepiece comprising: a generator for converting external energy into electric energy; a secondary power source for storing the electric energy generated by the generator; a timepiece driving circuit for performing a time-keeping operation; and a time display circuit for displaying time information from the timepiece driving circuit, wherein, the timepiece driving circuit is connected in parallel to the secondary power source; and the secondary power source comprises an equivalent capacitive component for storing an electric charge and a resistive component formed by a part of the equivalent capacitive component. The resistance value of the resistive component is set to a value such that a voltage drop is caused, whereby when the generator generates a current equal to or greater than a predetermined value, a voltage to be applied to the timepiece driving circuit by the generator is equal to or greater than the lowest operation starting voltage.
