サンプル・ホールド手法を応用した生糸繊度信号の波形整形

抄録

An equipment for waveform arrangement was devised to arrange the size signal waveform of raw silk during reeling by applying the sample and hold technique. Furthermore the fundamental characteristics of the equipment were researched, the following results were obtained.
The method of waveform arrangement is to integrate the applied analogue size signal for a set time and hold its value by means of integrator.
In the low frequency range, the frequency of the input has an effects on the output waveform of the proposed device and the waveform is characteristic. On the other hand, the frequency of size signal (80 to 95HZ) in the practical reeling speed range (180 to 210m/min) has no effect upon the output waveform of the device.
The device is a kind of low pass filter because it restrains the high frequency range.
It can be concluded that the optimum range of integration time (=hold time) is from 0.7 to 1.0 sec for practical size control.
