Abstract: A forming method wherein a billet (31, 66, 77, 87, 107, 128, 136, 144, 153, 77B, 77C) comprising a metal-based composite material (27) prepared by mixing an aluminum alloy (22) and a ceramic (15) is subjected to pressure forming to manufacture a formed article, which comprises carrying out the pressure forming by the use of different compression ratios for different portions of the formed article, wherein a compression ratio means the ratio of the height of a billet before the pressure forming to height of the billet after the pressure forming. The above forming method allows the manufacture of a formed article having different volume contents 8Vf) of the ceramic for different portions thereof.

Abstract: The present invention provides elastic polyurethane yarns which possess excellent elongation, recoverability, heat resistance and chemical resistance, as well as a method of manufacturing the same. The elastic polyurethane yarns comprise a polyurethane being composed mainly of a polymeric diol and a diisocyanate, and contains through incorporation a compound having within the molecule a phosphorus-nitrogen interatomic bond(s). The process can produce the elastic polyurethane yarns by adding to a solution of the polyurethane a compound having within the molecule a phosphorus-nitrogen interatomic bond(s), followed by spinning.

Abstract: A brake drum has its strength elevated in its disk portion. The brake drum is formed from a composition having ceramics dispersed in a matrix. The disk portion has a high ceramic content and thereby a high strength. Its cylindrical portion has a ceramic content decreasing gradually from the outer edge of the disk portion.

Abstract: A brake drum has its strength elevated in its disk portion. The brake drum is formed from a composition having ceramics dispersed in a matrix. The disk portion has a high ceramic content and thereby a high strength. The brake drum has a disk portion and a cylindrical portion. The disk portion has a first ceramic content by volume and the cylindrical portion has a second ceramic content by volume that is less than the first ceramic content by volume as a result of the application of a higher compression ratio to the disk portion.

Abstract: An apparatus for supplying molten steel and a continuous casting method therewith are described. The apparatus is equipped with a tundish 1 having an upper nozzle 2 at the bottom, a flow control mechanism 3 disposed below the upper nozzle 2, an immersion nozzle 4 formed by a refractory material having a good electrical conductivity, one electrode 5 disposed in the inner space of the tundish 1, the other electrode 6 disposed in the immersion nozzle 4, and a power supply 7 connected to the electrodes 5 and 6. In the method, the molten steel is supplied into a mold in the state of supplying an electric current between the inner surface of the immersion nozzle 4 and the molten steel 8 passing through the inside thereof by utilizing the apparatus for supplying molten steel. The deposition of the Al oxide or the like in the molten steel onto the inner surface of the immersion nozzle and others can be prevented, and thereby the generation of the surface defects in the products can also be prevented.

Abstract: An image forming apparatus includes an original read-out station which is provided on an image forming apparatus body and on which an original is placed and read out in a predetermined read-out position, a digitizer for designating an area of the original, and an automatic document feeder for feeding an original to the read-out position. The automatic document feeder and the digitizer are mounted on the image forming apparatus body for rotation about respective axes between their respective operative positions where they are opposed to the original read-out station and their respective retracted positions where they are away from the original read-out station to open the original read-out station.

Abstract: Steel is continuously cast in a mold at a casting speed of 2.5 to 10 m/min while the mold is oscillated so as to satisfy the relationship 450≦(S×f/Vc)≦1000, wherein S is the stroke of mold oscillation in mm, f is the frequency of mold oscillation in cycles per minute, and Vc is the casting speed in m/min.

Abstract: An abrasive sheet for fine texture processing has threads planted uniformly on a surface of a flexible base sheet and abrasive particles are attached by a binder to each of these threads uniformly over a specified distance from the tip such that the threads remain free to move independently without getting stuck to each other. Such an abrasive sheet can be manufactured by gravure processing with the separation between a gravure roller and a back roller adjusted according to the distance over which a coating material including the abrasive particles can be applied to the threads.
