摘要： A method for melting and/or refining metals and a cooling device for the graphite electrode used for the same are disclosed. Melting and/or refining of metal such as steel-making are performed in an electric arc furnace by energizing three graphite electrode sets each corresponding to each phase of a three-phase AC power source and consisting of a vertical succession of graphite electrodes as typically shown at 10 in FIGS. 2, 3 and 4, connected to one another via nipples.During the melting and/or refining of metal, a cooling liquid 11, substantially consisting of water for instance, is continuously blown against the outer periphery 10a of at least one of each set of graphite electrodes, specifically a graphite electrode 10 extending between an electrode holder and a furnace top cover. The liquid coolant 11 is jet not in the horizontal direction but in a downwardly or upwardly inclined direction at an angle of 10.degree. to 35.degree. C. with respect to the horizontal.

摘要： An electromagnetic wave absorber comprising a surface layer made of a composite of fibers having an electrical specific resistance of more than 10.sup.4 .OMEGA.cm and a resin, and a wave absorbing layer made of a composite containing silicon carbide fibers having an electrical specific resistance of from 10.sup.-2 to 10.sup.4 .OMEGA.cm. The composite used in the surface layer may be prepared, for example, by impregnating the resin in between the fibers after they have been treated to be a woven cloth, mat or felt or unidirectionally arranged fibers. If a wave absorbing layer is to be made of a composite containing the silicon carbide fibers and a resin, then the composite may be prepared in the same way as above.

摘要： This vane type compressor includes: a main body comprising a cylinder block formed with a bore and end members closing the ends of the bore; a rotor received within the main body in the bore so as to be rotatable about an axis extending in its longitudinal direction, its surface being formed with several slots extending in its longitudinal direction; and several vanes, each slidably fitted into one of the slots with its outer edge bearing against the inside surface of the bore in the main body. The material from which the vanes are formed is a composite material, comprising carbon and a metal including a substantial proportion of aluminum, and further including a substantial quantity of aluminum carbide, which holds the composite material together well and prevents the metal from coming away therefrom. This aluminum carbide may lie between the carbon and the reinforcing metal, and may be in a quantity of from about 1% to about 20%. The rotor may be made from cast iron, or from a material which has a similar coefficient of thermal expansion to the material for the vanes; this means that the vanes always fit well into the slots, no matter what may be the operating temperature of the compressor.
