摘要： A method is provided for reducing skin-friction of a ship moving through bubbly flow fields generated in proximity of hull surfaces by jetting gas through a plurality of jet nozzles provided on hull surfaces of the ship. The gas flow rate is controlled so as to establish a peak void fraction in a turbulent boundary layer, by applying an observation that the location of a peak void fraction shifts away in a direction normal to the hull surface with increasing gas flow rate through the jet nozzles.

摘要： A flat blow molding machine adapted to extrude flat hollow parison from clearance between a flat core and a flat die surrounding the core, characterized in that both ends of the die are slidable in a width direction with respect to a center, the core is replaceable in accordance with expansion and contraction of the die in the width direction. According to this construction, it is possible to change the width of the flat hollow parison extruded from the clearance between the core and the die by sliding the both ends of the die in the width direction and replacing the core upon expansion and contraction of the core in the width direction. Further, if the flat core is constructed from a planar replaceable portion and curved (three dimensional) non-replaceable portions and only the planar replaceable portion is exchanged upon replacement, preparing a plurality of inexpensive-to-manufacture planar replaceable portions having different lengths is enough and the cost is reduced. Accordingly, the width of the hollow flat parison extruded from the clearance between the flat core and the flat die can be changed.

摘要： There are provided an even number of paired roll-shift type rolling mills 12a, 12b and a controller 16 for controlling the rolling mills 12a, 12b. Each of upper and lower work rolls 13 of each of the roll-shift type rolling mills has a predetermined crown curve and has a roll shifting mechanism 14 for axially shifting the upper and lower work rolls relative to each other. The controller 16 determines a shift amount of each rolling mill in order to obtain a predetermined cross section shape of a steel plate, shifts the work rolls of the rolling mill on the upstream side paired every rolling coil to thereby disperse wear on the roll surface, and moves the work rolls of the rolling mill on the downstream side of the pair in a predetermined direction by the same distance, thereby canceling the change in the cross section shape of the plate caused by the shifting operation for the wear dispersion.
