摘要： A high-sensitive magnetometer has two SQUIDs each comprising a superconducting loop with one or more Josephson junctions and also has a coil comprising a continuous loop for providing magnetic flux of input signals to each of the SQUIDs in opposite directions. The magnetic flux of the input signals is detected by sums of output voltages of the SQUIDs. Magnetic flux noises equally applied on the two SQUID are cancelled by the continuous loop and at addition of the output voltages of the SQUIDs, thus large output signals can be obtained because sums of the two SQUID output signals are obtained.

摘要： A sampling type measuring device wherein an analog signal is measured by sampling the analog signal, converting each value obtained by sampling into digital form, and then processing the digital values. Exponential averaging calculation is performed directly on the digital values. Thus, no provision or time is needed to regulate the sampling period, thereby shortening the time required to perform measurement.

摘要： A superconducting logic circuit is configured by using two kinds of input-output type quantum flux parametrons (QFP), that is, a periodically excited input-output type QFP and an arbitrarily excited input-output type QFP. The periodically excited QFP is excited by periodically varying exciting magnetic flux to amplify a binary magnetic flux. The arbitrarily excited QFP is excited by magnetic flux output signals of upstream QFPs.

摘要： A fluxoid type superconducting logic element essentially comprises a single main superconductor loop and a switching element connected across the main superconductor loop. When the switching element is open, a permanent current flows in the main superconductor loop of the logic element at a cryogenic temperature, thereby sustaining a half-odd integer multiple of magnetic flux unit in each half of said main loop. When a small amount of input magnetic flux is applied to one half of the main loop and the switch is closed, the distribution of the magnetic flux varies according to the quantum theory to allow an integer multiple of magnetic flux to occupy each separated domain of the main loop. These two different magnetic flux distributions can be used to represent a binary state.

摘要： A magnetic field measurement system including a pick-up coil is not moved but fixed. Strips of superconducting material are arranged in a plane with narrow slits between the strips. The strips are moved very near the pick-up coil along the plane. From output variations of a SQUID magnetometer during the movement, a magnitude of a static field perpendicular to the plane of the strips is obtained.

摘要： A head with a pick-up coil is attached to a supporter so that the head is freely movable along the direction perpendicular to the surface of a superconductor. Fluid spouted from the spout hole of the head maintains the height (gap space) of the head from the surface. The head is firmly fixed to the supporter in the direction along the surface. Since the relative position of the head in the direction along the surface of the superconductor is changable by drive means for moving the superconductor or the head, the distribution of the magnetic flux which is trapped in the superconductor is measured by scanning the surface of the superconductor with pick-up coil.
