Title: Clock device
Inventor: MURAKI SHIGEHARU
IPC: G04G99/00
Filed: 1994-07-06
Abstract: PURPOSE:To provide a clock device capable of preventing the advance of the clock when noise is mixed into a power source by shaping the waveform of the power voltage, outputting the pulses corresponding to the power frequency, and providing a back-up clock ticking the time based on an oscillator. CONSTITUTION:The voltage cycle range corresponding to the power frequency is set in advance. When pulses are generated from a wave-form shaping circuit 2A at the reference cycle, the pulses are counted to tick the time, and the time is written into a crystal clock 3 at a constant cycle, e.g. at every minute. When the pulse interval becomes longer than the reference time, it is judged that a power stoppage or a momentary stoppage occurs, and the time is ticked by the crystal clock 3 for a fixed period, e.g. until 00 second of the next minute of the crystal watch 3 or until 00 second of the next minute after the electric power is recovered. When pulses are generated at the cycle shorter than the reference cycle, it is considered that noise is mixed, the time is likewise ticked by the crystal clock 3 until 00 second of the next minute, and the clock is switched to a back-up clock synchronized with the power frequency after 00 second of the minute at the reference cycle.

Distributions of light quantities of the diffracted light rays 142a, 142b are respectively guided to different light receiving parts and when the difference between outputs of respective light receiving parts is calculated, it becomes a push-pull signal.  That is, when, in the beam splitting means 9, the area is splitted into beam-split areas 141a, 141b by a splitting line roughly parallel with a T direction, the diffracted light rays 142a and 142b are respectively made incident on the area 141a and the area 141b and the push-pull signal is obtained by respectively guiding the diffracted light rays to different light receiving parts.
