Tunnel diode nor logic circuit

Claim 1

IN COMBINATION, A TUNNEL DIODE HAVING TWO STABLE OPERATING STATES, SAID TUNNEL DIODE EXHIBITING DIFFERENT POTENTIAL DROPS THEREACROSS IN EACH OF SAID STABLE STATES, SAID TUNNEL DIODE HAVING AN ANODE AND A CATHODE, INPUT MEANS COMPRISING A PLURALITY OF DIODES CONNECTED TOGETHER TO FORM A LOGIC NETWORK FOR PROVIDING INPUT SIGNALS HAVING DIFFERNT LEVELS, A FIRST BACKWARD DIODE CONNECTED BETWEEN SAID INPUT MEANS AND THE CATHODE OF SAID TUNNEL DIODE, A CURRENT SINK CONNECTED TO SAID INPUT MEANS AND SAID FIRST BACKWARD DIODE, SAID FIRST BACKWARD DIODE SO POLED THAT CONVENTIONAL CURRENT MAY FLOW THERETHROUGH FROM SAID TUNNEL DIODE TO SAID CURRENT SINK, A SOURCE OF PERIODIC PULSES CONNECTED TO SAID INPUT MEANS, SAID CURRENT SINK AND SAID FIRST BACKWARD DIODE, SAID SOURCE PROVIDING CURRENT TO SAID CURRENT SINK TO REVERSE BIAS SAID FIRST BACKWARD DIODE EXCEPT DURING THE APPLICATION OF SAID PERIODIC PULSES, SAID INPUT MEANS PROVIDING CURRENT TO SAID CURRENT SINK TO REVERSE BIAS SAID FIRT BACKWARD DIODE WHEN ONE INPUT SIGNAL LEVEL IS APPLIED, BIAS MEANS CONNECTED TO SAID TUNNEL DIODE FOR BIASING SAID TUNNEL DIODE TO ONE OF SAID STABLE STATES, A CURRENT SOURCE, A SECOND BACKWARD DIODE CONNECTED BETWEEN SAID CURRENT SOURCE AND SAID ANODE OF SAID TUNNEL DIODE, SAID CURRENT SOURCE PROVIDING CURRENT FLOW THROUGH SAID TUNNEL DIODE TO SAID CURRENT SINK ONLY WHEN SAID FIRST BACKWARD DIODE IS FORWARD BIASED SUCH THAT SAID TUNNEL DIODE SWITCHES FROM SAID ONE STABLE STATE TO THE OTHER STABLE STATE, A POTENTIAL SOURCE, A THIRD BACKWARD DIODE CONNECTED BETWEEN SAID POTENTIAL SOURCE AND SAID CATHODE OF SAID TUNNEL DIODE, OUTPUT MEANS CONNECTED TO SAID ANODE OF SAID TUNNEL DIODE FOR PROVIDING DIFFERENT OUTPUT SIGNALS IN ACCORDANCE WITH DIFFERENT STABLE STATES OF SAID TUNNEL DIODE, SAID POTENTIAL SOURCE AND SAID THIRD BACKWARD DIODE PROVIDING A CLAMPING NETWORK SUCH THAT SAID OUTPUT MEANS PROVIDES ACCURATE OUTPUT SIGNALS, AND RESET MEANS CONNECTED TO SAID TUNNEL DIODE FOR SWITCHING SAID TUNNEL DIODE FROM SAID OTHER STABLE STATE TO SAID ONE STABLE STATE.
