Abstract: An austenitic stainless steel flux cored wire may provide a welded metal having excellent cryogenic temperature toughness; a welded metal from the wire may have excellent cryogenic temperature toughness; and a welding method may involve such wire(s). An austenitic stainless steel flux cored wire in which a flux is filled in a steel-made shell. The flux cored wire may contain Si, Mn, Ni, Cr, C, P, and N in amounts each falling within a specified range relative to the entire mass of the wire, with the remainder made up by Fe and unavoidable impurities, and X1 is 17.5 to 22.0 inclusive, as calculated by formula (1): X1=[Ni]W+0.5×[Cr]W+1.6×[Mn]W+0.5×[Si]W+15×[C]W??(1), wherein, in formula (1), [Ni]W, [Cr]W, [Mn]W, [Si]W and [C]W represent the contents (% by mass) of Ni, Cr, Mn, Si, and C, relative to the entire mass of the wire.

Abstract: A video signal processor comprises a video signal receiving circuit for receiving a video signal from outside, and a sub-image signal generating circuit for generating an on-screen image signal corresponding to a fixed-pixel on-screen image to be displayed overlapping a video image. The video signal processor further comprises an interface circuit for converting the video signal received by the video signal receiving circuit into a fixed-pixel video signal, and synthesizing the converted video signal with the on-screen image signal generated by the sub-image signal generating circuit. The sub-image signal generating circuit generates the on-screen image signal to adjust the number of pixels included in the vertical direction in accordance with the generation scheme of the video signal.

Abstract: A reference signal having either twice or four times the frequency of a color burst signal (2fsc or 4fsc) is divided into a plurality of divided signals, each having the same frequency as that of the color burst signal, or an fsc frequency. In addition, a reference signal is delayed by a predetermined amount to thereby generate a delay signal. One of the divided signals is output in synchronism with this delay signal as a first divided signal having a predetermined delay. When this first divided signal is used as a color burst signal, the remaining divided signals resultantly all have phases shifted by a predetermined amount with respect to the color burst signal. With this arrangement, some of the divided signals can be used intact as a color signal, while the others may also be used after being delayed by a predetermined amount.

Abstract: A method for starting continuous slab casting capable of facilitating withdrawal of a dummy bar to start smooth continuous slab casting is provided at the start of casting of continuous slab casting, where lateral side plates 2 of the mold 10 are pinched by longitudinal side plates 1 of the mold and are adjustable in the slab width direction; where a dummy bar 4 is set at a desired level at the center in a width-variable, continuous casting mold; and clearances each between lateral side plates 2 and the dummy bar 4 are adjusted to 1-3 mm, while maintaining the lateral side plates 2 vertically, then sealing materials 5 are filled into the clearances; then molten steel is poured into the mold; and then the top ends of the lateral side plates 2 are made more apart outwardly, thereby giving a downwardly tapered profile to the lateral side plates 2, when no more poured molten steel is passed into the clearance between the formed solidified shell 6a and the plates 1 and 2, while withdrawing the dummy bar 4 downward
