出力として得られる。(Function) Oxide superconductor is used near the critical magnetic field. Then, since the resistance change of the superconductor is very large in response to a small change in the magnetic field, by connecting a DC power supply in series with the superconductor, a small change in the input magnetic field can be obtained as a large current change output. It will be done.

となり、電流増幅効果が得られる。As in No. 1111, the input signal is transmitted to the oxide superconductor 1 as an external magnetic field via the input signal coil 2. The oxide superconductor 2 is connected in series with an output DC power source 3, and as the resistance of the superconductor changes greatly depending on the input signal, the current flowing therein also changes sharply. This becomes the output, and a current amplification effect can be obtained.
