Abstract: A method of controlling the effective impedance of a low-impedance high-temperature superconducting cable (“HTS cable”). Passive or active control circuitry is used to create a current in the shielding conductor of the HTS cable which opposes the current in the primary conductor. In the case of a three-phase conductor, magnetic cross-coupling between the phases is exploited. The magnitude of the magnetic field is used to alter the HTS cable's effective impedance. The result is the creation of a controlled and substantially-higher effective impedance for the HTS cable. The creation of the higher impedance allows the HTS cable to be connected in parallel with conventional lines while regulating the amount of current flowing through the HTS cable.

Abstract: Disclosed is a method of molding a resin coated bearing. When a molten resin is injected toward a substantially central portion of a disk space of forming dies from a sprue formed on an upper die, the molten resin is filled into a cavity through a film gate after the molten resin is led to the disk space from a pin gate, so that any weld is absent on a resin member, which covers an outer race, thus enabling uniformizing a coating member in resin strength and suppressing generation of crack on the coating member even at the time of high loading.
