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： The invention provides an electronic device capable of increasing a braking torque of an electric power generator without causing a significant reduction in electric power generated by the electric power generator. Preferably; an electronically controlled mechanical clock includes an electric power generator 20 for converting mechanical energy transmitted from a spring via a wheel train to electrical energy and a rotation controller for controlling the rotation period of the electric power generator 20. The rotation controller includes switches 21 and 22 capable of connecting two terminals of the electric power generator into a closed loop state, a chopping signal generator for generating two or more types of chopping signals different in duty ratio or frequency for use in a strong braking operation, and chopping signal selection means 80 for selecting one signal from the two or more types of chopping signals, wherein, in the strong braking operation, the selected chopping signal is applied to the switches so as to control the electric power generator in a chopping fashion. The strong braking operation is performed in one of two modes such that a higher priority is given to generation of electric power or the braking torque depending on the mode thereby achieving an increase in the braking torque of the electric power generator without causing a significant reduction in the voltage generated by the electric power generator 20.

摘要： The present invention provides a rotation controller adjusting the speed of a rotary member (103). Phase difference compensating means (118) outputs a phase difference compensating signal (119) corresponding to a phase difference between a rotation signal of the rotary member (103) and a target signal, and frequency difference compensating means (114) outputs a frequency difference compensating signal (115) corresponding to a frequency difference between these signals. The rotary member (103) is braking-controlled by means of these signals. Use of the phase difference compensating signal (119) permits achievement of PLL control, and maintenance within the locking range allows a stable rotation control with a high response. Further, use of the frequency difference compensating signal (115) makes it possible to quickly bring the control within the locking range even when the rotary member (103) deviates from the target signal, and thus to carry out a control with a high response even upon riseup of the rotary member (103).
