Document Type and Number:
Japanese Patent JP2856463
Kind Code:
B2
Abstract:
PURPOSE:To release the magnetic trap in any superconducting circuit by a method wherein multiple resistor units are contained in a resistor circuit while exceeding two each of the resistor units are extended in a juxtaposed state to be connected to a power supply so that the sum of current running to the juxtaposed resistor units may be brought to nothing. CONSTITUTION:Multiple resistor units 22a, 22b are contained in a resistor circuit 20. The resistor units are arranged so that exceeding two each of the units may be extended in a juxtaposed state. Although these resistor units are heated by connecting to a power supply to feed current, the sum of current running to the juxtaposed resistor units is brought to nothing. For example, the resistor units 22a, 22b are extended in the juxtaposed state; one end is connected to a power supply 24a while the other end is connected to a superconductor wire to make a closed circuit; on the other hand, current is supplied from one end of the resistor 22b and led out of one end of the resistor 22a. That is, I21+I22=0. Furthermore, the resistors 22c, 22d...22i are extended in the juxtaposed state to be connected to another power supply 24b for supplying currents I11, I12...I19 to be specified I11+I12...I19=0.
