Abstract

871,059. Circuits of superconductive elements. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 11, 1958 [July 11, 1957], No. 22325/58. Class 40 (9). [Also in Group XXXVI] The cryotron flip-flop of Fig. 8 is constructed from a cryotron stock material which comprises two lengths of a wire having alternate sections of materials which are superconducting at the same temperature in the absence of a magnetic field but require different values of magnetic field to render them resistive. The two lengths of wire being intertwined so that each section of each wire requiring a high magnetic field to render it resistive is coiled, to form a control coil, round the section of the other wire which requires the lower magnetic field to render it resistive. The control section when energized produces sufficient magnetic field in the gate section around which it is coiled, to render that section resistive, without becoming resistive itself. Existing connections in the stock material 46, 48, 50, 54 and 56, shown dotted, are broken, the two conductors being welded together at 7<SP>1</SP>. The extra connection between the gate conductor of K3<SP>1</SP> and the gate conductor of K2<SP>1</SP> is made at 52 and that between the control conductors of K5<SP>1</SP> and K6<SP>1</SP> made at 24. K3<SP>1</SP> and K4<SP>1</SP> form input gates, a pulse on K3<SP>1</SP>, for example, switching conduction through K1<SP>1</SP>g, K2<SP>1</SP>C, K4<SP>1</SP>g, K6<SP>1</SP>C and a pulse applied to K4<SP>1</SP>C switching conduction through K1<SP>1</SP>C, K2<SP>1</SP>g, K3<SP>1</SP>g and K5<SP>1</SP>C. The position of the trigger at any time being indicated by the state of K5<SP>1</SP>g and K6<SP>1</SP>g the output gates.
