In a state where a gas barrier sheet ( ) having a gas barrier layer is held between a heat plate ( ) and a pressing plate, the gas barrier sheet is disposed between two molds together with a sub tank ( ) and a separator ( ) constituting attachment parts, the molds are then closed and a resin is injection-molded forming a resin layer ( ). A method for manufacturing a resin container by melt-adhering an intermediate molded product ( ) and another intermediate molded product ( ) constituting a pair therewith by heating with a heat plate ( ) thereafter, and a resin container manufactured by this manufacturing method.

Manufacturing method for a resin container

Wear-resisting iron base sintered alloy obtained by sintering a metal powder composed of, by weight, 15-25% chromium, 0-3% molybdenum, 1-5% copper, 0.3-0.8% phosphorus and 2.0-4.0% carbon, with the balance iron and less than 2% impurities, to a density of more than 7.3 g/cm.sup.3.

Wear-resisting sintered alloy

An upset-forged poppet valve wherein at least the head portion and a part of the neck is made of a high temperature super alloy while the remaining portion is made of a conventional valve steel, said two materials being connected by friction welding before said valve is forged. The method comprises two steps of first friction-welding two rods of said two materials and then forming the connected single rod into the poppet valve by upset-forging.
