182 Sending method of signal for electronic clock JP10992678 1978-09-07 JPS5536763A 1980-03-14 NAKAMURA JIYUNPEI
PURPOSE: To transmit accurate signals by sending out signals containing a plurality of different time data per second at a signal interval longer than the width of the pulse driven by a step motor of an analog electronic clock. CONSTITUTION: Signals A 1 and B 1 containing one time datum at every second and every 0.5 second, or signals A 2 and B 2 containing two different time data at every second and every 0.5 second are sent out from an electronic clock. The time intervals T 1 and T 2 between these signals are longer than the width of the pulse driven by a step motor of an analog electronic clock on a receiving side. COPYRIGHT: (C)1980,JPO&Japio

184 Clock for car JP8920878 1978-07-20 JPS5516262A 1980-02-04 MITAMURA KENICHI; MIZOTE MASAYOSHI
PURPOSE: To selectively connect several kinds of clock drive portions by means of one kind of drive circuit, by modulating frequency dividing signals with comparatively high frequency dividing signals with comparatively low frequency. CONSTITUTION: A frequency dividing circuit 1b of a drive circuit 1 divides the reference frequency of a crystal oscillation circuit 1a, generates clock pulses in 64Hz and 1/12Hz, inputs the pulses to a modulation circuit 1c and sends out modulation signals to terminals X, Y. A two pointers system clock drive portion 2 takes pulses in 1/12Hz in a motor by connecting the input terminals of the motor to the terminals X, Y. In this case, the winding of the motor functions as a fillter element because an AC motor is used, thus directly driving the motor by modulation signals by means of the circuit 1c. If the drive portion is also connected to the terminals X, Y in a three pointers system clock needing clock signals in 64Hz, the motor is driven in the same manner as mentioned above when employing the AC motor. When using a DC motor, the motor can be driven if continuous signals in 64Hz are obtained by employing an OR gate. COPYRIGHT: (C)1980,JPO&Japio

186 Centralized control type clock JP7800778 1978-06-29 JPS556223A 1980-01-17 KANASUGI MOTOYOSHI
PURPOSE: To accomplish a highly accurate time informing service over a wide area by digitally transmitting a transmission time. CONSTITUTION: The time from its generator 11 is converted into digital characters at 12. These characters are subjected to direct-alternating conversion at 13 and further to pulse modulation at 14 until they are transmitted. The modulated signals of a receiver 21 are subjected to code conversion at 22 and displayed as the time by a display 23. COPYRIGHT: (C)1980,JPO&Japio

190 Electronic master and subordinate watch JP1458178 1978-02-10 JPS54107777A 1979-08-23 SHIMANO KEIJI
PURPOSE: To simplify constitution and transmit the time from the master watch to the sub-watch without malfunction by using an alarm speaker in transmission. CONSTITUTION: The synthesized carrier of the frequency divided outputs of the watch part 1 of a master watch such as the one corresponding to the resonance frequency of an alarm speaker 5 of a sub-watch is made to the time displaying carrier by a gate or the like whose opening and closing are controlled by the output of the time displaying shift register or the like of a time data making part and is then radiated from the speaker 4 of the master watch. It is then well received without the effect of noise, etc. in a speaker 5 of narrow band frequency characteristics. Hence, the watch part 8 of the sub-watch is controlled via time correcting part 7 according to the receiving signal of the speaker 5. COPYRIGHT: (C)1979,JPO&Japio
