* C
* R
* C & R determine the length of the pulse.\nWhen the oscilator drops voltage across C\nthe resistor R is responsible to charge C.
* When the oscilator drops the voltage across C,\nthe capacitor drops the voltabe in the base of\ntransistor cutting it off. This raises the voltage\nin the collector of transistor charging capacitors\nconnected to it. After C charges enoughtly the\ntransistor enables again dropping the voltage on\nits collector, generating a negative voltage on\nthe other side of capacitors.
