Abstract: A WC-based cemented carbide contains, in terms of mass %, Co of 10% to 40%; and Cu of 5% to 15%, the balance consisting of at least one selected from the group consisting of Ti, Zr and Cr, and W, B, C and inevitable impurities. Thus, it is possible to provide a WC-based cemented carbide having a high abrasion resistance while adopting a configuration advantageous for a high thermal conductivity.

Abstract: Provided is a ring-rolled member manufacturing method enabling stabilization of the attitude of the ring material without generating a defect and the like in the resulting ring-rolled member even when the main roll of the ring-rolling device is provided with the flange portions positioned on upper and lower sides of the ring material. A ring-rolling device used in the ring-rolled member manufacturing method of the present invention is provided with a main roll 10 and a mandrel roll 20. An outer peripheral face of the main roll includes a recessed portion 12 to accommodate the ring material and an outer peripheral face of the mandrel roll 20, an upper flange portion 11 positioned on an upper side thereof, and a lower flange portion 13 positioned on a lower side thereof. An inner face of the recessed portion includes a rolling face 12S to be in contact with an outer peripheral face of the ring material, an upper face on the upper flange portion side, and a lower face 13S on the lower flange portion side, the lower face 13S having a slope in such a way that an opening of the recessed portion 12 is enlarged. The slope starts from within a range of a distance corresponding to a thickness of the ring-rolled member from a line of intersection between the lower face 13S and the rolling face 12S. An angle of the slope is greater than 0.3° and no greater than 9° with reference to the perpendicular plane.

Abstract: A multicore cable is provided with coaxial cables, each of which includes an inner conductor, an insulator covering around the inner conductor, and an outer conductor arranged around the insulator. The outer conductor is exposed, and the outer conductors of some of the coaxial cables are covered by grounding conductors that are to be electrically grounded. Each of the outer conductors of the coaxial cables is electrically grounded by contacting the grounding conductor or the outer conductor of another one of the coaxial cables.
