Abstract: According to a process for hot-dip galvanization of the present invention, a steel sheet is treated by the oxidization/reduction method for better quality of galvanization and then hot-dip galvanized. An annealing line of equipment for hot-dip galvanization is composed of a non-oxidizing zone, an oxidizing zone, and a reducing zone, in his order. A steel sheet containing elements liable to oxidize more easily than iron is oxidized by blowing flames onto it in the oxidizing zone according to the oxidization/reduction method. Further, the steel sheet is reduced and annealed in the reducing zone.

Abstract: The present invention relates to a photocatalytic material having a visible light activity which includes a tungsten-doped titanium oxide or a tungsten/gallium-codoped titanium oxide, and a divalent copper salt and/or a trivalent iron salt supported on a surface of the doped or codoped titanium oxide, and a process for producing the photocatalytic material.

Abstract: This invention provides a photocatalyst material, which can be produced at low cost without using platinum, particularly a visible light response-type photocatalyst material, a material having a photocatalyst mechanism not possessed by the conventional photocatalyst material, a process for producing the material, and a method for decomposing a contaminant using the material. The photocatalyst material comprises a) an oxide of a first metal and b) an aqua complex salt of a second metal. In this case, for the oxide of a first metal, the redox potential of a conduction band lower end in the oxide is on a rather negative side than 0.2 V (a value as measured at pH=0, vs. reference electrode potential). For the aqua complex salt of a second metal, the redox potential of a second metal ion in the aqua complex salt is on a rather negative side than 3.0 V (a value as measured at pH=0, vs. reference electrode potential).

Abstract: Disclosed is a high-strength hot dip galvannealed steel sheet having high powdering resistance produced by employing such a constitution that a Fe—Zn alloy plated layer is provided on at least one side of a basis steel sheet and a region in which Al (atomic %)/Zn (atomic %)?0.10 is present in a thickness of 300 ? or more from the surface of the plated layer along the depth direction of the plated layer. Also disclosed is a hot dip galvannealed steel sheet whose formability is greatly improved by optionally specifying chemical composition and structure of the basis steel sheet.

Abstract: A divalent copper salt and/or trivalent iron salt is supported on a surface of a metal ion-doped titanium oxide obtained by doping titanium oxide with metal ions to give a metal ion-doped titanium oxide with a valence band potential of 3 V or more (vs. SHE, pH=0) and a bandgap of 3 V or less between the valence band and an energy level of electrons excited from the valence band (including conduction band minimum potential and isolated potential). The metal ion-doped titanium oxide can be made to exhibit strong oxidative decomposition activity when irradiated with visible light based on the fact the divalent copper salt or trivalent iron salt functions as a catalyst for multi-electron reduction of oxygen.

A desired member is bonded to the panel through the inserts and the face plates which are bonded together. The inserts are disposed in selected honeycomb cells of the honeycomb core when the honeycomb core is assembled with the face plates, or the inserts are inserted into the selected honeycomb cells which are open to the opening or a preliminary hole formed before the opening is cut. Alternatively, the inserts are positioned relative to the face plates before the honeycomb core members are disposed relative to the inserts. The honeycomb panel may be produced by various methods disclosed.

Abstract: A plate fin heat exchanger adapted to applications using superhigh-pressure fluids was fabricated by brazing, the heat exchanger using as fin stock an alloy consisting essentially of 0.3 to 1.0 wt. % Si, 0.05 to 0.25 wt. % Cu, 0.6 to 1.5 wt. % Mn and 0.45 to 0.9 wt. % Mg, the balance being aluminum and impurities, wherein said impurities contain up to 0.8 wt. % Fe.At least one component selected from the group consisting of 0.05 to 0.25 wt. % Cr, 0.01 to 0.25 wt. % Ti, 0.03 to 0.25 wt. % Zr and 0.01 to 0.25 wt. % V may be added to the above fin alloy stock.By using the above plate fin, excessive silicon diffusion from a brazing alloy into the fin, which may cause reduction of width of the brazed joint, is suppressed, and as a result, lowering of the bonding strength of the brazed joint is eliminated.
