Abstract: The invention provides a galvannealed steel sheet which has an oxide layer having 10 nm or larger thickness on the plateau of the coating layer flattened by temper rolling. With the use of the galvannealed steel sheet, no powdering occurs during press-forming, and stable and excellent sliding performance is attained. By selecting the area percentage of the plateau of the flattened coating layer to a range from 20 to 80%, making the coating layer single layer of &dgr;1 phase, and letting &zgr; phase exist in the &dgr;1 phase, further improved sliding performance and anti-powdering property are obtained.

Abstract: There are disclosed a silicate-containing sheet which comprises a silicate of one metal or at least two composite metals, which metal and metals are selected from the group consisting of the groups 4 to 13 series 4-metals of the periodic table, the groups 4 to 15 series 5-metals of the periodic table, and the lanthanoids series metals, and are preferably selected from the group consisting of Ti, Fe, Co, Ni, Cu, Zn, Ga, Zr, Ag, In, Sn, Sb and Ce; and further a label comprising the above silicate-containing sheet. The silicate-containing sheet mentioned above can afford a functional sheet which has catalytic actions such as ultraviolet rays-attenuating properties, antimicrobial properties and antifouling properties at a low manufacturing cost.

Abstract: A hot-dip galvanized steel sheet is produced by rough rolling a steel, finish rolling the rough rolled steel at a temperature of Ar3 point or more, coiling the finish rolled steel at a temperature of 700° C. or less, and hot-dip galvanizing the coiled steel at a pre-plating heating temperature of Ac1 to Ac3. A continuous hot-dip galvanizing operation is performed by soaking a pickled strip at a temperature of 750 to 850° C., cooling the soaked strip to a temperature range of 600° C. or less at a cooling rate of 1 to 50° C. per second, hot-dip galvanizing the cooled strip, and cooling the galvanized strip so that the residence time at 400 to 600° C. is within 200 seconds. The steel sheet has a structure consisting essentially of ferrite and martensite.

Abstract: An adhesive sheet for wafer setting, comprising a wafer setting part composed of an expansible film and an adhesive layer for wafer setting and a marginal part outside the wafer setting part,wherein the marginal part has an antiexpansibility greater than that of the wafer setting part. This enables secure expansion in a process for producing an electronic component.
