The steel contains C: not more than 0.008 wt %, Si: not more than 0.5 wt %, Mn: not more than 1.0 wt %, P: not more than 0.15 wt %, S: not more than 0.02 wt %, Al: 0.010 to 0.10 wt %, N: not more than 0.008 wt %, and at least one element selected from the group consisting of Ti and Nb which is contained in an amount satisfying the relationship of 1.2 (C/12+N/14).ltoreq.(Ti/48+Nb/93). In at least one pass, rolling is conducted within a temperatures range lower than the Ar3 transformation point but not lower than 500.degree. C., in such a manner that the roll radius R (mm) and the blank thickness t (mm) before rolling by rolls satisfy the relationships of R.ltoreq.200 and R.sup.2 .times..sqroot.t.ltoreq.100000, and the total rolling reduction at temperature lower than the Ar3 transformation point is not lower than 60%. The hot-rolled steel sheet possesses a high level of Lankford value, and is free from cold-working embrittlement. The method may include the step of obtaining, after the rolling, pickling, annealing and hot dip galvanizing under certain conditions, a surface-treated steel sheet having excellent deep-drawability.

摘要： An apparatus includes a first switch circuit in an active mode and a second switch circuit in a standby mode. The apparatus receives high-priority packets and low-priority packets. Each switch circuit stores the high-priority packets and the low-priority packets into first and second buffers, respectively. The each switch circuit performs packet-readout processing reading out a packet from the first and second buffers where the packet-readout processing is performed on the first buffer on a priority basis. The apparatus controls the first switch circuit so that a back-pressure time for the high-priority packets becomes longer with increasing amount of data transmitted by the high-priority packets, when a low-priority packet outputted from the first switch circuit is determined to be a packet that has been received at a first time that is later than a second time at which another low-priority packet outputted from the second switch circuit has been received.
