Abstract

The persistent current circuit includes four paths A, B, C and D. Each forms with each other path a closed superconductive loop so that the circuit includes six such loops. Persistent currents are established in these loops by energizing a control conductor connected between the terminals A and N.

Current Gain Storage

The persistent current circuit includes four paths A, B, C and D. Each forms with each other path a closed superconductive loop so that the circuit includes six such loops. Persistent currents are established in these loops by energizing a control conductor connected between the terminals A and N.

This control conductor includes a control section arranged adjacent each path. This is effective when the control conductor is energized to introduce resistance into the path and provide a flux linking the loops of which the path forms a part. With the coupling between the control sections and the paths A, B and C being the same, there is no net flux in the loops formed by paths A, B and C, themselves, when a signal is applied to the control conductor. There is a net flux, however, in the loops formed by each of these paths with path D. The signal applied to the control conductor is terminated in such a way that each of these paths becomes superconductive at a time when there is a net flux threading each of these loops of which path D forms a part. Thus, there is a persistent current produced in each of these three loops. The persistent current in path D, which forms a part of each loop, is equal to the sum of the current flowing in paths A, B and C. In this way, a larger persistent current is established in path D than would be the case if only one control conductor and control path were utilized. The output of the circuit is derived from the gate...
