Claim 1
Independent Claim
201 words
A FLIP-FLOP COMPRISNG A FIRST AMPLIFYING CIRCUIT MEMBER HAVING FIRST, SECOND AND THIRD, ELECTRODES AND OPERATIVE TO CONTROL CONDUCTION BETWEEN SAID FIRST AND SECOND ELECTRODES IN RESPONSE TO THE VOLTAGE BETWEEN SAID FIRST AND THIRD ELECTRODES, A SECOND AMPLIFYING CIRCUIT MEMBER HAVING FIRST, SECOND AND THIRD ELECTRODES AND OPERATIVE TO CONTOL THE CONDITION BETWEEN SAID FIRST AND SECOND ELECTRODES IN RESPONSE TO THE VOLTAGE BETWEEN SAID FIRST AND THIRD ELECTRODES, A SOURCE OF D.C. POWER ADAPTED TO SUPPLY A D.C. VOLTAGE BETWEEN FIRST AND SECOND OUTPUT TERMINALS, A FIRST RESISTANCE CONNECTED BETWEEN THE SECOND ELECTRODE OF SAID FIRST AMPLIFYING CIRCUIT MEMBER AND THE FIRST TERMINAL OF SAID SOURCE OF D.C. POWER, A SECOND RESISTANCE CONNECTED BETWEEN THE SECOND ELECTRODES OF SAID SECOND AMPLIFYING CIRCUIT MEMBER AND THE FIRST TERMINAL OF SAID SOURCE OF D.C. POWER, A TUNNEL DIODE CONNECTED BETWEEN THE FIRST ELECTRODE OF SAID FIRST AMPLIFYING CIRCUIT MEMBER AND THE SECOND TERMINAL OF SAID SOURCE OF D.C. POWER, ELECTRICALLY CONDUCTING MEANS CONNECTED BETWEEN THE FIRST TERMINAL OF SAID SECOND AMPLIFYING CIRCUIT MEMBER AND THE SECOND TERMINAL OF SAID SOURCE OF D.C. POWER, MEANS DRIVING THE THIRD TERMINAL OF SAID SECOND AMPLIFYING CIRCUIT MEMBER WITH THE VOLTAGE SWINGS AT THE SECOND
