度差を維持するために、必然的に大形になる。The above prior art requires a dedicated refrigerator because it operates at liquid helium temperature. As shown in FIG. 2, a cryogenic container 31 for liquid helium is filled with liquid helium 33, a computer circuit 32 is crushed therein, and the heat generated by the circuit and the heat flowing in from the outside are removed. A refrigerator 34 is installed. Cryogenic container for liquid helium 3

導体計算機との入出力インターフェースの接続が困難に
なるという問題もある。Furthermore, with the current technology, the refrigerator is also large, measuring more than 3 m 2 . Since the continuous operation time of the refrigerator is limited and maintenance is difficult, there is a problem that continuous operation for a long period of time becomes difficult. Another problem is that the output voltage of the superconducting device at liquid helium temperature is as small as 2 to 3 mV, making it difficult to connect the input/output interface with a semiconductor computer at room temperature.
本発明の目的は、長時間連続動作が容易でしかも半導体
計算機との接続が容易な信号処理装置を実現することに
ある。An object of the present invention is to realize a signal processing device that can easily operate continuously for a long time and can be easily connected to a semiconductor computer.
上記目的は、高い臨界温度を持つ超電導体（高温超電導
体と略す）を用いた超電導デバイスによって計算機及び
信号処理装置を構成することにより達成される。The above object is achieved by configuring a computer and a signal processing device using a superconducting device using a superconductor having a high critical temperature (hereinafter referred to as a high-temperature superconductor).

間運転が容易にできる。When a Josephson junction is formed by a high-temperature superconductor,
Since the gap energy increases with the critical temperature (2Δ(0) = 3.52 kflTc), the output voltage increases (Vg > 50 mV when using a material with T = 140 at a liquid nitrogen temperature of 77), It is easy to connect to a normal semiconductor computer, and by combining it with a semiconductor element that is used after cooling, it is possible to increase the functionality or configure an input/output interface. In addition, regarding cooling, if the temperature is up to about 70, it is possible to operate continuously for a long time without maintenance with a n,tli refrigerator, and because liquid nitrogen, a by-product of liquid oxygen, can be used in large quantities and at low cost, it can be used for long periods of time. Easy to drive.

The displacer 23 only moves reciprocally within the refrigerator head 24, which is mechanically simple and allows long-term operation. A compressor 20 for supplying high-pressure gas to the refrigerator head 24 compresses gas by the rotational movement of a motor 21 and the reciprocating movement of pistons 22 in two opposing cylinders. The pistons 22 move in opposite directions to eliminate vibrations. With the compressor 20 whose piston 22 has a diameter of about 80 mm, a refrigerating capacity of several watts or less can be easily obtained. The heat conductive plate 25 is made of a good thermal conductor such as copper, and is combined with a heat pipe or the like if necessary.
