摘要： Impact detecting resistors (141), (143) of an impact detecting circuit (104) detect a counter electromotive force of a step motor (105) generated due to an impact. This counter electromotive force is amplified applying a predetermined period and a predetermined chopper-width by a chopper-amplifying waveform shaping circuit (118). Therefore, even a light impact can be detected. Inverters (145), (146) compare these impact detecting signals (S22), (S23) with a threshold value and detect an impact when the signals exceeds the threshold value. A controlling circuit (102) provides a lock pulse to the step motor (105) through signal lines (AA), (BB) when an impact is detected, brakes rotation of a rotor (162) thereby preventing a deviation of the time displayed with a second hand (106).

摘要： The power generated by a power generating means (1) of a power-generating type electronic clock is measured by a first power generating sensing means (101) and a second power generating sensing means (102). The power generation level required when the operation is changed from a normal mode to a power-saving mode and the power generation level required when the operation is changed from the power-saving mode back to the normal mode are made different to prevent the phenomenon that the operation changes frequently by imparting hysteresis characteristics to the power generation level which causes a change in the mode, thereby improving the power-saving effect.

摘要： A first voltage detector detects whether the voltage of a secondary cell has reached to 1.2V and a first timer counts a time duration for which the voltage is equal to or above 1.2V. If the time counted by the first timer reaches one hour, a second timer starts counting time for one hour. An amount of charge accumulated in the secondary cell is displays after counting of the one hour by the second timer is over. As a result, an accurate display of the amount of charge accumulated in the secondary cell can be achieved.

摘要： A small electronic apparatus provided with a functional display unit is formed of function driving device for generating function driving signals corresponding to a plurality of functions, a plurality of functional display devices corresponding to the functions and including first and second display devices, and a single motor electrically connected to the function driving devices and operated according to the function driving signals from the function driving device. A driving device transmits a driving force to the first functional display device, and an intermittent driving device is connected to the driving device to operate in association therewith. The intermittent driving device rotates the second display device intermittently. A clocking device is electrically connected to the function driving device. When a function of the first display device is completed, the clocking device sends a signal to reset the first display device to have a desired positional relation between the driving device and the intermittent driving device.
