Transistor switching circuit

Claim 1

A MONOSTABLE MULTIVIBRATOR HAVING A STABLE AND A QUASI-STABLE STATE COMPRISING FIRST AND SECOND TRANSISTORS EACH HAVING AT LEAST AN EMITTER, A BASE AND A COLLECTOR, MEANS FOR NORMALLY MAINTAINING CONDUCTIVE SAID FIRST TRANSISTOR AND FOR NORMALLY MAINTAINING NON-CONDUCTIVE SAID SECOND TRANSISTOR TO PROVIDE SAID STABLE STATE FOR SAID MULTIVIBRATOR, IMPEDANCE MEANS CROSS-CONNECTING SAID COLLECTOR OF SAID SECOND TRANSISTOR AND SAID BASE OF SAID FIRST TRANSISTOR, MEANS INCLUDING A COUPLING CAPACITOR IN SERIES-CIRCUIT RELATION WITH A DIODE CROSS-CONNECTING SAID COLLECTOR OF SAID FIRST TRANSISTOR AND SAID BASE OF SAID SECOND TRANSISTOR, MEANS FOR RENDERING CONDUCTIVE SAID SECOND TRANSISTOR AND FOR RENDERING NON-CONDUCTIVE SAID FIRST TRANSISTOR AND SAID DIODE TO PROVIDE SAID QUASI-STABLE STATE FOR SAID MULTIVIBRATOR, RESISTOR HAVING ONE END THEREOF CONNECTED TO THE COMMON CONNECTION OF SAID CAPACITOR AND SAID DIODE, CHARGING MEANS INCLUDING A SOURCE OF SUPPLY HAVING A CONNECTION TO THE OTHER END OF SAID RESISTOR FOR PRODUCING A CHARGING CURRENT FOR FLOW THROUGH SAID CAPACITOR WHEN SAID DIODE IS RENDERED NONCONDUCTIVE, SAID CHARGING CURRENT WHEN ABOVE A PREDETERMINED VALUE MAINTAINING SAID SECOND TRANSISTOR CONDUCTIVE, SAID CHARGING CURRENT DECREASING IN VALUE AS SAID CAPACITOR ACCUMULATES A CHARGE, SAID DIODE BEING RENDERED CONDUCTIVE UPON ACQUIREMENT OF A PREDETERMINED CHARGE BY SAID COUPLING CAPACITOR, MEANS FOR RAPIDLY DIMINISHING TO ZERO AS A LIMIT SAID CHARGING CURRENT WHEN SAID DIODE IS RENDERED CONDUCTIVE, SAID SECOND TRANSISTOR BEING RENDERED NON-CONDUCTIVE WHEN SAID CHARGING CURRENT HAS DECREASED BELOW SAID PREDETERMINED VALUE, MEANS FOR RENDERING CONDUCTIVE SAID FIRST TRANSISTOR WHEN SAID SECOND TRANSISTOR IS RENDERED NON-CONDUCTIVE TO RETURN SAID MULTIVIBRATOR TO ITS STABLE STATE, AND MEANS INCLUDING AN ADDITIONAL DIODE CONNECTED BETWEEN SAID BASE OF SAID SECOND TRANSISTOR AND SAID EMITTER OF SAID FIRST TRANSISTOR, WHEREBY A DISCHARGE PATH IS PROVIDED FOR SAID CAPACITOR WHICH INCLUDES SAID FIRST TRANSISTOR IN ITS CONDUCTIVE STATE AND SAID ADDITIONAL DIODE IN ITS CONDUCTIVE STATE WHICH PATH IS OF LOW IMPEDANCE COMPARED WITH THE IMPEDANCE OF SAID CHARGING MEANS AND SAID RESISTOR.
