Title: Electronic timepieces
IPC: H03K23/00
Filed: 1974-04-17
Abstract: 1463534 Electronic timepieces SUWA SEIKOSHA KK 17 April 1974 [19 April 1973] 16799/74 Heading G3T [Also in Division G4] The running rate of an electronic timepiece is adjusted by periodically shortening the period of the timing signal f 1  fed by a binary frequency divider chain (B) Fig. 1 to a driver circuit F of a display H, by the amount of an error #T, an oscillator circuit A being arranged to produce a signal f o  at a frequency lower than required to make the signal f 1  have a 1 second period. As illustrated in Fig. 1A, 1B, it is assumed that there are four divider stages, and that the required period for f 1  is 1 second. The amount #T of correction necessary is determined in any known manner by comparison of signal f 1  and an external reference signal and is assumed to be <SP>1</SP>/ 16  secs which is the width of a pulse from divider stage FF 1. Accordingly, it is arranged to reduce the period of the output f 1  of FF4 by #T. This is effected by gates G and AND gate E, the gates G being pre-set in accordance with determined value of #T. When a signal g 1  - g n  from the divider, is at logic "o" level a respective gate circuit G 1  - G n  produces an output g' 1  - g n  to the AND gate E. The AND gate, is arranged to generate a single reset pulse to reset all the stages of the divider to zero each time when stages FF 2 -FF 4  are in the "o" state (Fig. 1B) and FF1 is going to "1" state - at instant "a". Thereby one pulse from FF1 is eliminated and the period of f 1  is reduced to 1 second; a new cycle commences and the foregoing is repeated, the effective division ratio of the divider having been changed.  In another embodiment Fig. 2 (not shown) the gate circuit G passes a reset pulse from a pulse generator (D) triggered by the timing signal f 1  to reset appropriate stages of the binary dividercounter.
