Abstract: In a state where a gas barrier sheet (10) having a gas barrier layer is held between a heat plate (12) and a pressing plate, the gas barrier sheet is disposed between two molds together with a sub tank (44) and a separator (46) constituting attachment parts, the molds are then closed and a resin is injection-molded forming a resin layer (36). A method for manufacturing a resin container by melt-adhering an intermediate molded product (38) and another intermediate molded product (38) constituting a pair therewith by heating with a heat plate (12) thereafter, and a resin container manufactured by this manufacturing method.

Abstract: In a magnetic core for a non-contact displacement sensor comprising a detecting coil, a coil receiving member and a terminal, the coil receiving member is comprised of a green compact made of insulated soft magnetic powder and an insulating layer covering the green compact, and an organic resin is filled in a closed space of the coil receiving member.

Abstract: 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.

Abstract: 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.
