Filed: 1992-06-03
Abstract: PURPOSE: To make possible hyperfine patterning in the degree of 0.1 μm by providing a pattern mask while using a semispherical particle layer or using a layer filling the valley section of semispherical particle layer. CONSTITUTION: A semispherical particle layer 3 is formed on any arbitrary layer 2 to be etched on a semiconductor wafer 1. Afterwards, the surface of semispherical particle layer 3 forming a mountain and a valley is coated with the arbitrary layer 2 and another arbitrary layer 4 having an etching selection ratio higher than that of semispherical particle layer for prescribed thickness, and this is etched back so as to expose only the top section of semispherical particle layer 3. Next, with the arbitrary layer 4 remaining at the valley section of semispherical particle layer 3 as the mask, the exposed mountain section of semispherical particle layer 3 is etched and the layer 2 is partially exposed so that the mask pattern can be formed.  When this is etched back, the arbitrary layer 2 performing top hyperfine patterning in the degree of 0.1 μm limited as the valley section of semispherical particle layer 3 can be provided.

Title: Alminum alloy sheet for can excellent in ironing property
Inventor: KANBAYASHI MIKI
IPC: B21D22/28
Filed: 1987-07-03
Abstract: PURPOSE:To improve the ironing property of an Al alloy sheet by providing a recessed and/or projecting part in the specified dimensional diameter, depth and height and at mean center intervals on the sheet surface and forming a fine recess on the whole surface further, if necessary. CONSTITUTION:The recessed and/or projecting part in 1-500mu diameter, 0.1-200mu depth or height and 3-2000mu mean center interval is formed on the plate surface. A fine recess is formed on the whole plate surface further, if necessary. In this case, the formation of the recessed or projecting part is executed by the rolling roll arranging a fine recess periodically on the surface by a laser beam. The ironing of the sheet is thus improved due to the part becoming of the recess acting as a lubrication oil pool. The lubrication effect is further improved as the lubrication oil is filtrated into the fine recess on the whole surface and consequently the ironing property of the Al alloy sheet is improved.

IPC: B21B23/00
Filed: 1987-07-06
Abstract: PURPOSE:To prevent faulty biting and to obtain a seamless steel pipe excellent in quality, by rolling the end part of the pipe in tapered shape so that the thickness of the end part becomes thinner toward the pipe end, in the rolling stage by a piercing mill or elongator of Mannessmann type. CONSTITUTION:As to the blank pipe whose end part is rolled in the tapered shape, in case of subjecting to elongation rolling successively, a reduction ratio of a sectional area of the pipe end is smaller than that of the central part of the pipe. Therefore, when the pipe end part is elongation rolled in tapered shape, the rolling load is managed with small load, so wears of tools are reduced and flows of the pipe is not generated. Further, the faulty biting and failing to roll caused by deteriorating the shape of flange parts are not taken place. Furthermore, at the time of rolling of the pipe end part in the tapered shape by the piercing mill or the elongator of Mannessmann type, with respect to the elongation rolling, as the material temp. is high and the rolling speed is slow, the control of the rolling to make the pipe end in the tapered shape is facilitated, the faulty biting and the faulty shape of the pipe end part are not generated.
