Filed: 1982-07-14
Abstract: PURPOSE:To provide a low friction type sintered alloy which is reinforced with the short metallic fibers suitable as a brake for vehicles by constituting said alloy of a sintered alloy consisting essentially of the metallic powder replaced partly or fully with the short metallic fibers. CONSTITUTION:In the case of using copper for the metal of the above-described metallic powder and short metallic fibers, short Cu fibers of, for example, 1-3mm. length for a part of, for example, CU powder, as well as Cu3P, a lubricant and a grinding material are added and mixed respectively at prescribed ratios to and with said Cu powder. The mixed powder is molded, for example, at 3 tons/cm<2> molding pressure, and the molding is sintered at 780 deg.C sintering temp., whereby the intended low friction type sintering alloy is manufactured. The sintered alloy has extremely low bulk hardness; therefore, when said alloy is used as a friction material, the content condition of the mating material is good and the thermal influence which is usually observed is too small to be observable with the eye. Since the alloy is melted and sintered in the state of reinforcing the same with the metallic fibers, the amt. of the lubricant, etc. to be filled is decreased and as a result, the sintered alloy having a low coefft. of friction, high hardness and high strength is provided.

Title: Post-heat treatment of weld heat-affected zone of seam welded steel pipe
Inventor: OHAMA HIROHISA
IPC: C21D9/08
Filed: 1985-06-07
Abstract: PURPOSE:To efficiently lower the hardness of weld heat-affected zones in a short time without necessitating a long annealing zone and without decreasing the pipe producing velocity by temporarily cooling the welded part to a specified temp. before the pipe is reheated and then tempering the pipe. CONSTITUTION:When a seam welded steel pipe is produced by low-frequency or high-frequency welding, the seam welded part heated by welding is temporarily quenched to a temp. >=50 deg.C lower than the Ms point of the pipe material. The cooling is carried out so that >=20% austenitic structure is not left and a martensite structure is formed. The pipe is then heated from 500 deg.C to (Ac1+50 deg.C) and then cooled. The martensite formed by quenching is tempered and the part affected by the welding heat is softened. A seam welded steel pipe produced by this method can be drastically bent and is provided with excellent quality characteristics.

Filed: 1991-04-26
Abstract: PURPOSE:To obtain high luminous intensity without raising driving voltage and shortening the life of electroluminescence element itself in a driving method of the electroluminescence element to control a time shared scanning period in a luminance state or non-luminance state. CONSTITUTION:An AC voltage is supplied in a high frequency at the beginning of a driving period set within a scanning period so as to bring an electroluminescence element early in a luminance state with high luminance.
