Resistor coupled transistor logic circuitry

Claim 1

A CIRCUIT COMPRISING, IN COMBINATION; A SEMI-CONDUCTIVE DEVICE HAVING AT LEAST A CONTROL ELECTRODE, A COLLECTOR ELECTRODE AND AN EMITTER ELECTRODE; A PLURALITY OF FIRST IMPEDANCE ELEMENTS; A LIKE PLURALITY OF SECOND IMPEDANCE ELEMENTS; A THIRD IMPEDANCE ELEMENT; A LIKE PLURALITY OF INPUT TERMINALS EACH CONNECTED THROUGH A RESPECTIVE SECOND IMPEDANCE ELEMENT TO SAID CONTROL ELECTRODE; MEANS FOR PROVIDING A POWER SUPPLY OF PREDETERMINED POLARITY, CONNECTED THROUGH SAID THIRD IMPEDANCE ELEMENT TO SAID CONTROL ELECTRODE PROVIDING A CURRENT OF PREDETERMINED DIRECTION THERETHROUGH; MEANS FOR PROVIDING A POWER SUPPLY OF OPPOSITE POLARITY, CONNECTED THROUGH A RESPECTIVE FIRST IMPEDANCE TO A RESPECTIVE INPUT TERMINAL PROVIDING A CONTROL CURRENT OF OPPOSITE DIRECTION THROUGH SAID CONTROL ELECTRODE; SAID CONTROL CURRENT OF OPPOSITE DIRECTION BEING SUBSTANTIALLY DIVERTED FROM SAID CONTROL ELECTRODE IN RESPONSE TO AN INPUT SIGNAL TO SAID RESPECTIVE INPUT TERMINAL.
