    摘要: The improved nickel-base heat-resistant alloy consists of 13.1-15.0% Cr (all percentages that follows are by weight), 8.5-10.5% Co, 1.0-3.5% Mo, 3.5-4.5% W, 3.0-5.5% Ta, 3.5-4.5% Al, 2.2-3.2% Ti, 0.06-0.12% C, 0.005-0.025% B, 0.010-0.05% Zr and 1-100 ppm of Mg and/or Ca, in the optional presence of 0-1.5% Hf and/or 0-0.5% of at least one element of Pt, Rh and Re, with the remainder being Ni and incidental impurities. The alloy has high strength and high resistance to oxidation and corrosion at elevated temperatures and, hence, is suitable for use as a constituent material for machine parts that are to be exposed to elevated temperatures.

    摘要: A combination of a plug assembly to be attached to a printed wiring board, and a receptacle assembly to be attached to a shelf back-board. The plug assembly comprises a set of plug contacts mounted to a plug housing. The receptacle assembly comprises a receptacle housing capable of mating engagement with the plug housing, and a set of resilient, bladelike receptacle contacts mounted to the receptacle housing. Each bladelike receptacle contact has two protuberances formed in longitudinally spaced positions thereon. Each receptacle contact is so made that only one of the two protuberances thereon is normally held against one associated plug contact upon interfitting engagement of the receptacle housing with the plug housing. At least selected one of the receptacle contacts butts on a projection on the receptacle housing and is thereby resiliently displaced in such a direction that the two protuberances on the displaced receptacle contact are both held against one associated plug contact. Thus, when the plug assembly is being inserted in the receptacle assembly, the plug contacts engage some of the receptacle contacts earlier than the others.
