A packaging box, for a golf ball, is formed by folding a packaging sheet comprising a decomposable laminate material consisting of a polylactic acid-containing polymer film and a sheet of paper laminated with the polylactic acid-containing polymer film. A portion corresponding to a window is cut out from the paper, and the window is covered with the polylactic acid-containing polymer film laminated on the paper. The window is formed straddlingly on two or three planes such that the polylactic acid-containing polymer film covering the window is bent perpendicularly at a boundary between the planes adjacent to each other. A raised portion is formed on the packaging sheet.

A vehicle door assembly comprises an inner panel integrally formed by upper and lower horizontal beams interconnected by front and rear upright beams, and an outer panel bonded to the inner panel. The frame portion comprises opposite front and rear U-shaped side frame members non-detachably attached to each other by upper and lower intermediate frame members so as to form a continuous perimeter. The side frame members are made of a first steel material and the intermediate frame members made of a second steel material, which is different from the first steel material. A method for manufacturing the inner panel comprises the steps: providing U-shaped sheets of the first steel material, providing top and bottom sheets of the second steel material, non-detachably connecting the U-shaped sheets to the top and bottom sheets so as to form a blank, and stamping the blank into the frame portion.

A foam material generator has a housing; transmission device on the housing; housing cavity within the housing; pressurizing stirring foaming wheel within the cavity; transmission device transmission shaft connected to the wheel; pressurizing stirrers on the wheel; pressurizing stirrer airflow-facing surface forms an inclined angle with a cross sectional surface in a wheel rotational axis direction; housing cavity inlet is on a cavity end, and a housing cavity outlet is on another end; encircling abrasive disc is on a cavity inner wall adjacent to the outlet; encircling abrasive disc inlet is at a encircling disc middle portion; vortex current abrasive foaming disc is on a wheel end adjacent to the encircling disc; vortex current abrasive foaming disc surface conforms to be in close proximity with an encircling disc surface; and vortex current abrasive foaming cavity is between the surfaces of the vortex current abrasive foam disc and encircling disc.

A high-strength, high-permeability steel sheet for picture tube band comprises, in mass percent, C: 0.003-0.010%, Si: 0.5-1.0%, Mn: 1.0-2.0%, P: 0.04-0.15%, S: not more than 0.02%, Al: not more than 0.030%, N: not more than 0.004% and the balance of Fe and unavoidable impurities, has a chemical composition satisfying C×Mn×P≧2.5×10−4, and has a ferrite crystal grain diameter of 10-100 μm and a yield stress of 300 N / mm2 or higher, and preferably has a specific permeability μ0.35 in a DC magnetic field of 0.35 Oe of 400 or higher. The steel sheet can be produced by regulating the hot-rolling coiling temperature to 600-700° C. and selecting an appropriate combination of the cold rolling reduction ratio and a final annealing temperature in the range of 750-900° C.

A first nitriding process step is performed in which a steel member is subjected to a nitriding process in a nitriding gas atmosphere having a nitriding potential with which a nitride compound layer having a γ′ phase or an ε phase is generated, and thereafter a second nitriding process step is performed in which the steel member is subjected to a nitriding process in a nitriding gas atmosphere having a nitriding potential lower than the nitriding potential in the first nitriding process step, to thereby precipitate the γ′ phase in the nitride compound layer. It is possible to generate the nitride compound layer having a desired phase mode uniformly all over a component to be treated and to manufacture a nitrided steel member high in pitting resistance and bending fatigue strength.

In a large-sized radiator core support manufactured by filling a mold cavity 2 with a resin material through injection, polypropylene (PP) containing carbon fiber in a range of 15 to 30 wt % is used as the resin material, and an average fiber length of the carbon fiber remaining after molding is set to 1.5 mm or more. Moreover, a spiral flow length L / D of the carbon fiber is set to 200 mm or more.
