PURPOSE:To make it possible to extract outputs at nearly the same point in time, by detecting the across voltage of a capacitor by voltage detecting circuits in integral networks. CONSTITUTION:As the electric power source is put to work, the charge of capacitor 40 starts by constant currents 35 and 41 and when its value exceeds the sum of bias voltage E and VBE1 of the 1st transistor 25 of the 1st integral network 24, the 1st transistor 25 turns on and gets saturated. As a result, electric current flows through resistance R26 to develop an R-volt potential difference and the voltage across capacitor 40 reaches (R+VBE1+E) volt, so that the 2nd transistor 37 in the 2nd integral network 36 also turns on. Thus, the 1st in-use circuit 34 and 2nd in-use circuit 43 can be put into operation nearly at the same time. |
