Alternately, the hot-dip Al- plated steel sheet may have a chromate coating in an amount of 5 to 100 mg/m2 on the surface, and it may also have a resin coating on the top surface. As a result, the  Al-plated steel sheet is excellent in elongation after Al plating. The Al-plated steel sheet is, therefore, significantly excellent in corrosion resistance subsequent to forming in the internal environment of fuel tanks compared with conventional steel sheets. Accordingly, the  Al-plated steel sheet also having excellent air-tightness after welding is most appropriate as a material for fuel tanks of automobiles.

Abstract: A digital broadcast receiver is provided which can reliably perform a seek operation for an ensemble. Upon a seek instruction, a system controller 38A makes a front end 2 sequentially tune in frequencies of a plurality of ensembles. When a NULL symbol is detected at some reception frequency, a frequency error detector 33A decodes carrier-components of PRS and judges whether a maximum correlation value of a correlation function calculated between the decoded carrier-components and a predetermined reference code is equal to or higher than a predetermined value. If the maximum correlation value is equal to or higher than the predetermined value, the seek operation is terminated. And frequency error data calculated by the frequency error detector 33A is output to an integrator 34.
