摘要： This invention provides a superconducting tunnel junction element showing satisfactory Josephson effect. The element includes a Bi-based layered compound such as Bi.sub.2 Sr.sub.2 (Ca.sub.0.6 Y.sub.0.4)Cu.sub.2 O.sub.8, Bi.sub.2 Sr.sub.2 Cu.sub.2 O.sub.6 and Bi.sub.2 Sr.sub.2 CaCu.sub.2 O.sub.8 as the barrier layer between the superconducting oxide electrodes. The structural matching of the superconducting oxide with the Bi-based compound is supposed to be good. Some kinds of Cu-based superconducting oxides such as YSr.sub.2 Cu.sub.2.7 Re.sub.0.3 O.sub.7, Sr.sub.2 CaCu.sub.2 O.sub.6 and (La.sub.0.9 Sr.sub.0.1).sub.2 CuO.sub.4 are used for the electrodes to obtain a Josephson element which can work at a high temperature. When using the superconducting oxides including Ba such as YBa.sub.2 Cu.sub.3 O.sub.7 for the electrode, forming a thin film between the electrode and the barrier is better to prevent Ba from reacting with Bi in the barrier layer. The superconducting device comprising the element has various uses such as magnetic detecting use, communicating use and computing use.

摘要： An effective high frequency oscillator is made of a plurality of Josephson devices. A high frequency converter as a high frequency circuit is made of the high frequency oscillator, nonlinear superconductor devices, and transmission line. Josephson devices are connected in parallel to make a superconductor module. Then superconductive modules are connected in series for high frequency via a phase locking circuit such as a thin film type capacitor to make the high frequency oscillator. Consequently, the high frequency oscillator is used as a local oscillator for a frequency converter. The high frequency system comprises a high frequency package housing a high frequency circuit, a cooling unit including a low temperature stage in thermal contact with the high frequency package, and a shielding case for housing the high frequency circuit and the low temperature stage. The high frequency system of the present invention provides a small-sized and power-saving high frequency circuit having operational stability.

摘要： In a small transmission line type high-frequency circuit element that has small loss due to conductor resistance and has a high Q value, an error in the dimension of a pattern, etc. can be corrected to adjust element characteristics. An elliptical shape resonator (12) that is formed of an electric conductor is formed on a substrate (11a), while a pair of input-output terminals (13) are formed on a substrate (11b). Substrate (11a) on which resonator (12) is formed and substrate (11b) on which input-output terminal (13) is formed are located parallel to each other, with a surface on which resonator (12) is formed and a surface on which input-output terminal (13) is formed being opposed. Substrates (11a) and (11b) that are located parallel to each other are relatively moved by a mechanical mechanism that uses a screw and moves slightly. Also, substrate (11a) is rotated by the mechanical mechanism that uses a screw and moves slightly around the center axis of resonator (12) as a rotation axis (18).
