Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
143 words
ELECTRONIC SWITCHING CIRCUIT, COMPRISING CURRENT SUPPLY MEANS, A LOAD CONNECTED TO SAID SUPPLY MEANS, GALVANOMAGNETIC MEMBER MEANS AND TUNNEL DIODE MEANS CONNECTED WITH EACH OTHER AND WITH SAD LOAD FOR JOINTLY SWITCHING THE CURRENT PASSING FROM SAID SUPPLY MEANS THROUGH SAID LOAD SAID MEMBER MEANS HAVING CONTROLLABLE MAGNETIC FIELD MEANS FOR CONTROLLING THE SWITCHING OPERATION BY GALVANOMAGNETIC VARIATION OF SAID MEMBER MEANS, SAID TUNNEL DIODE MEANS HAVING A CURRENT-VOLTAGE CHARACTERISTIC WITH A NEGATIVE RANGE BETWEEN A CURRENT MAXIMUM AT RELATIVELY LOW VOLTAGE AND A CURRENT MINIMUM AT HIGHER VOLTAGE, SAID NEGATIVE RANGE BEING MATCHED TO THE RANGE OF SAID GALVANOMAGNETIC VARIATION SO AS TO BE LOCATED WITHIN THE RANGE OF DIODE-CURRENT CHANGE DUE TO SAID VARIATION, WHEREBY SAID VARIATION CAUSES THE LOAD VOLTAGE TO SWITCH BETWEEN TWO LIMIT VALUES CORRESPONDING TO RESPECTIVE POINTS NEAR SAID MAXIMUM AND MINIMUM RESPECTIVELY OF SAID TUNNEL-DIODE CHARACTERISTIC.
