1. logical device comprises:

  • One high Tc ceramic superconductor, when temperature remained essentially in its critical temperature, this superconductor demonstrated magnetoresistive characteristic,Supply unit, it applies the controlled constant electric current to superconductor,Conductor means, be placed in the superconduction tagma and and the superconductor electric insulation so that apply magnetic field to superconductor according to the electric current that flows through this conductor means;

    AndCheckout gear, detect in the conductor means one or more than one signal code to the influence of superconductor resistance, it is characterized in that,Said ceramic superconductor comprises an elongate thin film, it has crystal boundary at random, as the weak coupling ceramic material, on said elongate thin film ceramic material is deposited at the bottom of the electrically insulating substrate, through the electric current of ceramic superconductor, is that the weak threshold field that be no more than 10 Gausses under this ceramic superconductor from zero resistance state-transition be limited resistance states in the critical magnetic field than this ceramic superconductor by control flows suitably;

    Said conductor means comprises the film strip conductor that at least one forms on said substrate, and the length dimension that has at least a part of said strip conductor to be parallel to said superconductor is extended.
