Abstract: An oxygen-absorbing compound has oxygen-absorbing properties and generates less odor. An oxygen-absorbing adhesive composition and a coating agent composition are produced using the oxygen-absorbing compound. The adhesive composition is used for forming an adhesive layer in a laminate for a packaging material, generates less odor, absorbs oxygen in a packaging bag or a packaging container to prevent the deterioration of a content in the packaging bag or the packaging container, and has an excellent balance among adhesion strength, the amount of generated odor and oxygen adsorption properties. The coating agent composition forms a coating layer for the surface of the laminate for a packaging material, generates less odor, and absorbs oxygen penetrating through the laminate or oxygen in a packaging bag or container. The oxygen-absorbing compound has one or two or more unsaturated five-membered rings that have a carbon-carbon double bond.

Abstract: A cavity is formed between stationary and movable mold members, and a runner is connected to a gate to the mold cavity to supply a molten resin material thereto. The stationary and movable mold members have bodies of an aluminum alloy of high heat conductivity and light weight. Iron base plating is applied at least to transfer wall surfaces of the cavity, leaving and exposing other wall surfaces in a non-plated state.

Abstract: For partially plating work surfaces, a tubular shield member is set around a work which is connected to a cathode, in face to face and in predetermined small gap relation with a non-plating surface or surfaces of a work. In a plating bath, an anode is located on the outer side of the shield member to cover the non-plating surface from the anode. Upon conducting current between the anode and cathode, a metallic coating is deposited specifically and selectively on a work surface or surfaces which are not covered by the shield member.

Abstract: The resistance welding method of different kinds of materials is the method for welding an iron material and an aluminum alloy material, and comprises the steps of: performing in advance a coating treatment at least to a portion of the aluminum alloy material, where resistance welding is performed, with any of iron and iron-base alloy and forming a surface layer; and performing resistance welding of the iron material and the aluminum alloy material through the surface layer, and the resistance welding may be any of spot welding and projection welding.

Abstract: A method for making an aluminium material which is electroplated on its aluminum or aluminium alloy base with iron or an iron alloy containing 2-20 weight % of chromium, and which can be utilized as a new structural or functional material in various industrial fields. The material is characterized in having an inter-diffusion layer produced between the base and the plating and/or having such fine cracks produced in the plating which can reserve well machine oil, work well for painting it, and be impregnated with a resin for improving its wear resistance and so on.
