する。Conventional mounting methods using superconducting phenomena include, for example, the ``IEEB spectrum'' technology.
[Problems to be Solved by the Invention] The above-mentioned conventional methods were usually used by being immersed in a container of liquid helium, etc., as shown in the figure shown in "Rum), May 1979 Issue, Page 27". In terms of technology, as shown in Figure 1, superconducting bag #1 is placed in a container 3 filled with a cryogen 2 such as liquid helium or sufficiently cooled helium gas, which makes it difficult to diagnose defective parts in, for example, a superconducting computer. Therefore, in the superconducting quantum interferometer, which is a highly sensitive magnetic flux meter, there were problems such as difficulty in bringing the magnetic flux sensing coil close enough to the target object〇 [Means to solve the problem] The above problem As shown in Fig. 2, a non-metallic superconducting material with a high critical temperature is used as the superconducting material, and a conductive material 1' placed outside a cryogen container is cooled by a heat sink 4 cooled by the cryogen. The solution is to employ Koki.

上記構造を実現で ′きる。In FIG. 2, since the heat sink 4 is cooled by the cryogen 2, the superconducting material 1' in close contact with the heat sink 4 is also cooled. With such a structure, it is difficult to cool the superconducting material below 10 degrees, which is the operating temperature of metallic superconducting materials, but some non-metallic superconducting materials have sufficiently high critical temperatures.
The above structure can be realized.
以下、実施例により本発明を説明する。 The present invention will be explained below with reference to Examples.

A superconducting material 5 mainly composed of CuO4 crystals is formed on the surface of a copper plate 6, a copper pipe 7 for flowing liquid nitrogen is welded to the back surface of the copper plate 6, and both sides are sandwiched between styrene heat insulating materials 8. By WRing liquid nitrogen into the pipe 7, the plate of this structure began to exhibit superconducting properties. In such a structure, the super conductive material 5 is not used as a refrigerant container, so it can be used as a wave reflecting plate, a structural material for a shield room, etc. This board was used to fabricate a shield room and a reflector for a parabolic antenna. Because the @ field is completely diamagnetic, it does not penetrate into the shield room, and the magnetic field inside the shield room is below the measurement limit.

By employing the structure of the present invention as described above, it is possible to realize a state conductive device which is difficult to realize when placed in a conventional cryogen container.

きた。The coil 9 is electrically connected to the Josephson junction element 10 placed in the cryogen container 3 and the external drive device 11,
A superconducting quantum interferometer was created. According to this embodiment, since the superconducting magnetic field detection coil 9 is installed outside the cryogen container 3, it is possible to bring the coil 9 close to the object to be measured, thereby improving measurement sensitivity and positional resolution. The Kosa was made.

It has advantages such as being able to improve the performance of superconducting quantum interferometers.

A superconducting plate made of Teflon (using Teflon) was formed into the shape of a bearing, and a shaft 12 made of a permanent magnet was fitted onto it. In such a structure, since the superconducting material 6 is placed outside the cryogen container, the shaft 12 can rotate without coming into contact with the cryogen, and due to the diamagnetic nature of the superconducting material, it can rotate smoothly without coming into contact with the cryogen. 0 to do
