Coupling transistor logic and other circuits

Claim 1

IN A TRANSISTOR CIRCUIT HAVING AT LEAST ONE INPUT TRANSISTOR AND AT LEAST ONE OUTPUT TRANSISTOR, EACH OF SAID TRANSISTORS HAVING A BASE ELECTRODE, AN EMITTER ELECTRODE AND A COLLECTOR ELECTRODE, SAID CIRCUIT INCLUDING A COUPLING TRANSISTOR HAVING A BASE ELECTRODE, AN EMITTER ELECTRODE AND A COLLECTOR ELECTRODE, EACH OF SAID TRANSISTORS BEING OF THE SAME TYPE, SAID BASE ELECTRODE OF SAID COUPLING TRANSISTOR BEING COUPLED TO A SOURCE OF CURRENT, ONE OF SAID ELECTRODES OTHER THAN THE NASE ELECTRODE OF SAID COUPLING TRANSISTOR BEING COUPLED TO O NE OF SAID ELECTRODES OTHER THAN THE BASE ELECTRODE OF SAID INPUT TRANSISTOR AND THE OTHER OF SAID EMITTER AND COLLECTOR ELECTRODES OF SAID COUPLING TRANSISTOR BEING COUPLED TO THE BASE ELECTRODE OF SAID OUTPUT TRANSISTOR, THE BASE ELECTRODE AND THE OTHER ELECTRODES OF SAID INPUT TRANSISTOR ADAPTED TO BE CONNECTED TO AN INPUT CIRCUIT, AND THE EMITTER AND COLLECTOR ELECTRODES OF SAID OUTPUT TRANSISTOR ADAPTED TO BE CONNECTED TO AN OUTPUT CIRCUIT.
