時間が遅れてしまう等の欠点があつた。 Conventionally, in order to operate clocks and timers accurately, the frequency of commercial AC power is directly counted using a ring counter, etc. In clocks, it is displayed digitally, and in timers, a switch is activated after a certain period of time. A method is being used to do so. This method naturally causes a large time error in areas where the AC power frequency is 50Hz and 60Hz, so it is necessary to make two types of products for 50Hz and 60Hz, and to differentiate by region. I have to sell it, and I'm mistaken.
If you use a 50Hz clock or timer with a 60Hz power supply, time will advance 6/5 times as fast, and if you use a 60Hz clock or timer with a 50Hz power supply, time will slow down to 5/6 the speed. There were some drawbacks, such as:

出来る。 Therefore, the object of the present invention is to provide a clock pulse generator that can be used for both 50Hz and 60Hz, which can generate pulses at a constant frequency using a simple circuit even when using a 50Hz or 60Hz AC power source. The invention will be explained below with reference to the drawings. In FIGS. 1 and 2, 1 is a DC power supply, and a series circuit of a resistor 2 and a capacitor 3, and a series circuit of a resistor 4 and a resistor 5 are connected to both ends of the DC power supply. Then, connect the connection point of resistor 2 and capacitor 3 to PUT
Connect the anode of PUT6, connect the gate of PUT6 to the connection point of resistor 4 and resistor 5, and
The cathode of 6 is connected to the negative line of DC power supply 1 through resistor 7, and a basic CR oscillation circuit is configured by PUT 6, which connects capacitor 3, resistors 2, 4,
It oscillates at a constant period determined by 5. On the other hand 8
is a 50Hz or 60Hz commercial AC power supply, one end of the AC power supply 8 is connected to the negative line of the DC power supply 1, and from the other end, the resistor 9, the anode of the Zener diode 10, the cathode of the Zener diode 10, and the negative line of the DC power supply 1 are connected. They are connected in series in the order of the negative line, and a capacitor 11 is connected to a connection point between the resistor 9 and the anode of the Zener diode 10 and a connection point between the resistor 4 and the resistor 5. Therefore, the AC power supply 8 is connected to both ends of the Zener diode 10.
In the case of 50Hz, the waveform 12 shown by the solid line appears as a trapezoidal wave, and in the case of 60Hz, the waveform 12' shown by the dotted line appears as a trapezoidal wave, and the pulse differentiated by the action of the capacitor 11 is multiplied by the gate DC voltage of PUT6. , 50Hz has a waveform of 13 shown by a solid line, and 60Hz has a waveform of 13' shown by a dotted line, which becomes the gate reference voltage of PUT6. Among the pulses included in the gate reference voltage of PUT6, the negative direction pulses have an interval of 5 pulses of 0.1 seconds at 50 Hz, and an interval of 6 pulses of 0.1 second at 60 Hz.
Here, the waveform shown in 14 shows the sawtooth voltage that repeatedly rises and rapidly drops over time.
6 anodes. In such a way that this sawtooth voltage 14 crosses the negative direction pulse at the 5th cycle interval included in the waveform 13 in the case of 50Hz.
By selecting resistor 2, capacitor 3, resistor 4, and resistor 5, it is possible to obtain pulses that appear at 0.1 second intervals at both ends of resistor 7 as shown by waveform 15. When AC power supply 8 is switched to 60Hz in this state, waveform 1
3', a negative direction negative pulse every 6th cycle interval,
It crosses waveform 14, which is also 0.1, and pulses with the same period can be obtained even at 50Hz and 60Hz.

したが、抵抗２，４，５及びコンデンサ３を適当
な値を選択する事により、0.1秒の整数倍周期の
パルス発生が可能である。実験結果によると、
0.6秒程度までなら非常に安定した動作を得る事
が出来た。 The above description has been about pulse generation with a period of 0.1 seconds, but by selecting appropriate values for the resistors 2, 4, and 5 and the capacitor 3, it is possible to generate pulses with a period that is an integral multiple of 0.1 seconds. According to the experimental results,
We were able to obtain very stable operation up to about 0.6 seconds.
