Abstract:
In order to obtain a cold rolled steel sheet having excellent press formability, a cold rolled steel sheet has, on a surface thereof, an organic-inorganic composite film containing: an organic resin; and a crystalline layered material. The organic-inorganic composite film has an average film thickness of 0.10 to 2.0 μm and contains 0.5 part or more by weight of the crystalline layered material as a solid with respect to 100 parts by weight of a solid of the organic resin. The crystalline layered material preferably is, for example, a layered double hydroxide represented by [M2+1-xM3+x(OH)2] [An−]x/n.zH2O, where: M2+ is one or more of Mg2+, Ca2+, Fe2+, Ni2+, and Zn2+; M3+ is one or more of Al3+, Fe3+, and Cr3+; and An− is one or more of OH−, CO32 , Cl−, and (SO4) 2−.
Abstract:
A copy and paste operation allows selection from a copy source display area to be copied from a display screen of a display unit and pasted to a paste destination display area without losing the original appearance and style. A processing unit determines from data generated on the style of a copy source and data on the paste destination style, whether the paste destination style would change the copy source style. If it is determined that the paste destination style would change the copy source style, the copy source style is processed into the paste destination style in order to make the paste destination style consistent with the copy source style. The paste destination display area then displays the copy source display area pasted therein with the copy source style.

Abstract:
In order to manufacture a chromate-coated lead-containing galvanized steel sheet having beautiful spangles and excellent anti-black patina and anti-white rust properties without relying upon any flushing treatment with Ni, etc., a lead-containing galvanized steel sheet obtained by plating in a galvanizing bath containing appropriate amounts of Pb and Al, and having beautiful spangles is coated with a chromate coating solution containing trivalent and hexavalent chromium ions in a molar ratio of 1/9 to 1/1, and nitrate ions in a molar ratio of 0.1 to 1.6 to the total of the chromium ions, preferably after treatment with an aqueous alkali solution having a pH of 9 or above, and washing with water, and the sheet is dried at an appropriate sheet temperature without being washed with water, whereby a chromate film having a coating weight of 5 to 50 mg/m2 is formed thereon. The lead and aluminum with which the galvanized surface is enriched are, as a result, removed effectively, thereby enabling excellent anti-black patina and anti-white rust properties to be obtained.
