摘要:
Chrome-coated stainless steel is provided that has better adhesion, even when it is being shaped, than conventional wet-type plating, and better atmospheric corrosion resistance than bare stainless steel. In addition, the chrome-coated stainless steel, provided by means of physical vapor deposition, also possesses the same color tone and luster as chromium, and thus has superior decorative compatibility with existing wet-type chrome plated parts.
摘要:
A metal plate is given an excellent decorative color by a multi-ceramic coating of a colored ceramic layer formed over the metal plate, the colored ceramic layer being made of at least one selected from the group consisting of nitrides and carbides of titanium, zirconium, hafnium, chromiun, niobium and aluminum and having a thickness of 0.1 .mu.m to 1 .mu.m ; and a transparent ceramic layer formed over the colored ceramic layer, the transparent ceramic layer being made of at least one of the group consisting of silicon oxide, silicon nitride and aluminum oxide and having a thickness of 0.1 .mu.m to 5 .mu.m. The depositions of the colored and transparent ceramic layers are effected by a dry process, and the order of deposition of the colored and transparent ceramic layers can be reversed.

The present invention provides a stainless steel most suitable as a metal base material for the weight sensor substrate of an automobile airbag, a method for producing said stainless steel and said weight sensor; and the stainless steel sheet comprises a high aluminiferous ferritic stainless steel containing Al of 2.5 to 8 mass % and comprising, in mass, C: 0.025% or less, N: 0.025% or less, the sum of C and N being 0.030% or less, and Nb: 0.05 to 0.5%, with the balance consisting of Fe and unavoidable impurities. Further, said stainless steel sheet may further contain, in mass, one or more of V: 0.05 to 0.4%, Ti: 0.02 to 0.2%, and Zr: 0.02 to 0.2%. The present invention makes it possible to control the difference in the average linear expansion coefficient between said stainless steel sheet and crystallized glass for a weight sensor to less than 10% in the temperature range from 20° C. to 900° C. and thus to improve the adhesiveness of said stainless steel sheet with said crystallized glass.

摘要:
A method of and an apparatus for simultaneously sizing a large number of long fiber yarns, in which number of warper's beams having a sufficient number of warps for weaving of cloth is divided into 2 or 3 sets of beams according to the total number of warps and the yarn diameter so that yarns in each divided set are placed in the width equal to that of said weaver's beam having a yarn pitch of over 3 times that of the yarn diameter, each warp sheet from divided warper's beams is sized and dried passing over one of the sizing and drying paths having a same distance of 2 or 3 systems placed in vertical levels under a same amount of draft, and then each yarn which is sized and dried in each system is wound onto a weaver's beam over a path of the same distance with a same amount of draft.
