    摘要: A magnetic shield which comprises: a plurality of metallic cylinders connected to each other in the axial direction thereof, each of the plurality of cylinders having at one end thereof an engaging section for receiving an end of an adjacent metallic cylinder to be connected thereto; and a film of a composite oxide superconducting material containing a Cu.sub.x O.sub.y -radical, formed on the entire inner surface of each of the plurality of cylinders, including the inner surface of the engaging section thereof. The above-mentioned magnetic shield can easily be scaled up and has a high magnetic shielding effect.

    摘要: An electric resistance seam welding method for a hard-to-weld steel sheet is disclosed which prevents the occurrence of flashes. The steel sheet has metal harder than tin and an intermetallic compound as coating layers, the sheet thickness of the steel sheet is 0.5 mm or less and portions of the sheet are overlapped for welding with an overlapping width in a range from 2.0 times to 2.3 times the sheet thickness.
