摘要： A method of producing a hot-dip galvannealed steel sheet from a very-low-carbon cold-rolled steel sheet containing not less than 0.01 wt % but not more than 0.1 wt % of Ti, by subjecting the cold rolled steel sheet to a process conducted in a continuous hot-dip galvanizing system including a heat treatment, hot-dip galvanizing and a subsequent galvannealing. The method is characterized by the steps of: subjecting the cold-rolled steel sheet to a degreasing and an acid cleaning; subjecting the degreased and acid-cleaned steel sheet to a heat treatment conducted in a reducing gas atmosphere; and cooling the heat-treated steel sheet at a temperature not lower than 380.degree. C. but not higher than the hot-dip galvanizing bath temperature, before the steel sheet is subjected to the hot-dip galvanizing. The very-low-carbon cold- rolled steel sheet contains, besides not less than 0.01 wt % but not more than 0.1 wt % of Ti, not more than 0.005 wt % of C, not less than 0.01 wt % but not more than 0.1 wt % of Al, not less than 0.01 wt % but not more than 0.1 wt % of Ti, and the balance substantially incidental inclusions and Fe.

摘要： A hot rolled steel sheet having a specific composition and having a specific small grain size of ferrite constituting the steel sheet has high resistances against secondary-work embrittlement and brazing embrittlement and is adapted for ultra-deep drawing. The specific small grain size of the ferrite can be obtained by limiting the hot rolling condition of a slab having the specific composition.

摘要： A fuel feed apparatus feeds fuel in a fuel tank to the outside of the fuel tank. The fuel feed apparatus includes a flange that covers an accommodation hole of the fuel tank, a fuel pump that pumps fuel, and a sub-tank accommodating the fuel pump. The sub-tank is capable of reciprocating relative to the flange in the axial direction of struts, which support the flange. The struts are positioned circumferentially outwardly to the sub-tank. The sub-tank has a lid 70. Holding portions are provided on the lid to axially movably hold the struts. Thus, an assembling work of the fuel feed apparatus can be eased without damaging internal components, when the struts are assembled.

摘要： A continuous dip-plating apparatus for a steel strip has a pot containing a metal melt which forms a plating bath, a device for causing the steel strip to run through the plating bath such that the steel strip makes a turn around a sink roll in the plating bath so as to be pulled upwardly above the surface of the plating bath, and a wiping device disposed above the pot and adapted for adjusting the amount of deposition of the metal melt to the steel strip. The apparatus further has a pair of flow regulating plates for suppressing deposition of dross to the steel strip. The flow regulating plates are arranged in parallel with and in the vicinity of the portion of the steel strip running upwardly through the plating bath with the upper ends of the flow regulating plates being disposed substantially at the same level as the plating bath. Preferably, the height of the portion of each flow regulating plate below the level of the surface of the plating bath is not smaller than 50 mm, while the distance between each flow regulating plate and the steel strip is preferably not greater than 80 mm. It is also preferred that the upper end of each flow regulating plate is positioned between a level which is 10 mm below the surface of the plating bath and a level which is 50 mm above the surface of the plating bath.
