  • Superconducting toggle flip-flop circuit and counter circuit
    Patent number: 5309038
    Abstract: A high-speed counter capable of counting the number of randomly incoming pulses is constructed by serially connecting a plurality of toggle flip-flop circuits, each of which is activated by input pulses and constructed from an rf-SQUID and the quantum flux parametron, whereby a high-speed computer or a high-speed measurement apparatus can be realised by the use of the high-speed counter.

  • Superconducting circuit
    Patent number: 4916335
    Abstract: There is provided a quantum flux parametron-type superconducting circuit in which a path with a Josephson device is connected in parallel with exciting inductors of the quantum flux parametron or inductors of exciting line magnetically coupled with the exciting inductors, thereby constructing a phase regulator.
