Abstract: 920,008. Superconductor circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 24, 1959 [Dec. 24, 1958], No. 43831/59. Class 40 (9). Two superconductive gate conductors 24, 26 are connected in parallel to a source 20 of constant current i2 and are self-biased by control coils 25, 27 connected in series with the conductors. The current i2 normally divides equally between the two branches as an increase in the current in one branch tends to drive the corresponding gate conductor more resistive. A signal current i1 in control coils 30, 31 aids the bias from coil 25 and opposes the bias from coil 27 to unbalance the circuit. There is a substantially linear relation between the signal current and the current in each branch. Two or more amplifiers may be connected in cascade. Specification 862,178 is referred to.
