Abstract: A method of manufacturing a pulp molding die, by providing a superplastic material plate having a plurality of preformed through-holes, closing the plurality of preformed through-holes, heating the superplastic material plate under a pressurized atmosphere, forming the plate into a desired shape, and uncovering the plurality of preformed through-holes of the plate, thereby forming the pulp molding die.

Abstract: An electromagnetic cooking container includes a non-magnetic titanium alloy plate having a specific resistivity not less than 80.times.10.sup.-6 .OMEGA..multidot.cm and not more than 200.times.10.sup.-6 .OMEGA..multidot.cm. The titanium alloy plate includes a titanium alloy layer, a plurality of laminated titanium alloy layers, or a plurality of kinds of titanium alloy layers. The titanium alloy plate is formed into the desired shape by a superplastic blow forming method in which the titanium alloy plate is forced on a surface of a mold or die by a gas pressure at a forming temperature not less than 500.degree. C. The container may further include a titanium oxide film formed on an inner cooking surface of the formed titanium alloy plate. Heat generation by electromagnetic induction is enabled and there are no problems of deformation, rust, or weight addition.

Abstract: This invention relates to a direct production process of a length of continuous thin two-phase stainless steel strip having excellent superplasticity and surface properties by casting molten two-phase stainless steel directly on either a single roller or a pair of rollers, so that the molten metal is quenched, and a small amount of austenite appears in ferrite matrix.
