Pulse shaping circuit

Claim 1

A PULSE SHAPING CIRCUIT COMPRISING FIRST AND SECOND TRANSISTORS EACH HAVING BASE, COLLECTOR, AND EMITTER ELECTRODES, PULSE GENERATING MEANS CONNECTED TO THE BASE ELECTRODE OF SAID FIRST TRANSISTOR TO RENDER SAID FIRST TRANSISTOR CONDUCTIVE AT PREDETERMINED INTERVALS, CIRCUIT MEANS CONNECTING THE BASE AND EMITTER ELECTRODES OF SAID SECOND TRANSISTOR TO PROVIDE A CURRENT SUFFICIENT TO SATURATE THE BASE-EMITTER JUNCTION OF SAID SECOND TRANSISTOR, AND MEANS SERIALLY CONNECTING THE EMITTER-COLLECTOR PATHS OF SAID FIRST AND SECOND TRANSISTORS BETWEEN A SOURCE OF POTENTIAL AND A PULSE STIMULATED UTILIZATION CIRCUIT SO THAT A PULSE APPLIED TO THE BASE ELECTRODE OF SAID FIRST TRANSISTOR CAUSES A CURRENT TO FLOW IN THE EMITTER-COLLECTOR PATH OF SAID FIRST TRANSISTOR IN THE FORWARD CONDUCTIVITY DIRECTION, AND IN THE EMITTERCOLLECTOR PATH OF SAID SECOND TRANSISTOR IN THE INVERSE CONDUCTIVITY DIRECTION, UNTIL SAID SECOND TRANSISTOR IS DRIVEN FROM A SATURATED CONDITION INTO CUT-OFF AND THE INVERSE CURRENT FLOW IS TERMINATED, WHEREBY A NARROW WIDTH PULSE IS TRANSMITTED TO SAID PULSE STIMULATED UTILIZATION CIRCUIT.
