    摘要： In a constant current circuit, a constant current is caused to flow through a resistor, thereby causing a constant voltage to occur across the resistor. This constant voltage is then superimposed on an output signal of an operational amplifier that is to be fed back to the drain of a field effect transistor, thereby maintaining the same potential in an AC manner between the output terminal of the operational amplifier and the drain of the field effect transistor. In this way, the gate and drain of the field effect transistor is caused to exhibit the same potential in an AC manner, so that no current will occur through the stray capacitance between the gate and drain of the field effect transistor. As a result, similarly to a case of using a feedback capacitor, the input impedance of the field effect transistor can be raised.

    摘要： A magnetometer comprising a superconducting loop including a magnetic flux detecting coil and a SQUID (Superconducting QUantum Interference Device) connected to the superconducting loop via magnetic flux. A negative inductance generating device is provided having two terminals for generating a negative inductance defined by the value of the derivative of generalized magnetic flux between the two terminals with current flowing between the terminals (d.PHI./dI) being negative. The inductance of the superconducting loop is decreased by the negative inductance generating device and input signals intensified by the negative inductance generating device are detected by the SQUID. A plurality of the superconducting loops may be provided to construct a gradiometer and a variable negative inductance generating device is provided to the respective superconducting loop to equalize and intensify the sensitivities of the detection coils.

    摘要： A pair of superconducting electrodes are so formed as to interpose a smeiconductor therebetween, and a control electrode is formed on the seimiconductor through an insulator film so as to control the superconductive weak coupling state in the semiconductor between the superconducting electrodes. The distance between the superconducting electrodes is determined by the thickness of the superconductor interposed between the two electrodes, whereby the interelectrode distance is settled with a high precision to improve the uniformity of the device characteristic.And in an arrangement where two superconducting electrodes are formed on a semiconductor layer and the superconductive weak coupling state between such two electrodes is controlled by a third electrode, the gain is increadable by furnishing a varied impurity distribution in the semiconductor layer.

    摘要： A superconductive large-scale integrated circuit chip comprises a plurality of pads, a superconductive line which short-circuits respectively adjacent pairs of the pads, and an input buffer circuit. The input buffer circuit includes a Josephson junction which is either in a superconducting state or a finite voltage state in response to a magnetic field established by current that is supplied to the superconductive line by flowing in from one of the two pads and flowing out from the other pad. The input buffer circuit wave-shapes the externally supplied signal into an amplitude-controlled signal, and the latter signal is led by a superconductive line to a circuit within the chip which requires the signal. Even when the external signal current has become abnormally great due to noise, etc., any circuit situated halfway within the chip can be prevented from malfunctioning from the magnetic flux generated by the large current.
