Abstract: A manufacturing method for a cup-shaped member including a corrugated portion includes a drawing step, a preliminary processing step, and a finishing step. In the preliminary processing step, at least preliminary large diameter portions in a preliminary corrugated portion are each formed to have a width larger than the size of each of the large diameter portions of the corrugated portion, thereby reducing an ironing resistance in the manufacturing of the cup-shaped member.

Abstract: It is an object of the present invention to provide a fuel oil composition for diesel engines showing good CFPP and lubricity, efficiently controlling PM emissions and containing sulfur at 0.05 wt. % or less. The present invention provides a fuel oil composition for diesel engines comprising a base stock which has normal paraffin compounds having a carbon number of 20 or more at 4.0 wt. % or less, specific carbon number distribution in the high-boiling normal paraffin compounds and polynuclear aromatic hydrocarbon compounds at 8.0 vol. % or less, contains sulfur at 0.05 wt. % or less, and is incorporated with 0.01 to 0.1 wt. % (as the active component) of an FI and 0.002 to 0.1 wt. % (as the active component) of a lubricity improver.

Abstract: A flooring material is composed by interpositioning at least one intermediate layer (2), in the form of a sheet that is weakly adhered to a sheet base material (1) to an extent that at least its upper surface can be easily peeled from said sheet base material (1), within said sheet base material corresponding to the bottoms of wiring grooves (6 and 7) formed in said sheet base material (1). A plurality of cuts are made along cut lines (4 and 5) of said flooring material at a depth that extends to the above-mentioned intermediate layer (2) at prescribed intervals. Wiring grooves (6 and 7) are formed by peeling off portions (1a and 1b) of the sheet base material (1) within said cut lines to enable wiring along said grooves (6 and 7).
