摘要： The present invention aims at providing a sophisticated segregation reducing technique which a conventional technique cannot achieve by finding the relationship between the casting structure and the segregation of components at the time of solidification and the heat treatment conditions. That is, the present invention aims at providing material for shadow masks which exhibits excellent quality with respect to streaks. A material for a shadow mask of the present invention is formed of a casting slab for preparing the shadow mask which comprises an Ni—Fe alloy containing 30 to 45% of Ni. The casting slab has a cast structure comprising a columnar crystal and/or a chill crystal in an amount of 99% or more. In particular, it is preferred that the casting slab contains no equiaxed crystal. To this end, such casting slab is prepared by a continuous casting method in which casting operation is carried out with no electromagnetic stirring and with maintaining a melt temperature of the non-solidificated part in the slab at a temperature equal to or more than the liquidus thereof. Further, the resultant slab is subjected to a heat treatment at a temperature for a time such that the K value becomes 150 &mgr;m or more, to thereby diffuse the segregation of Ni.

摘要： A polarization-maintaining optical fiber which exhibits an excellent polarization-maintaining performance and significantly low splice loss when spliced with a polarization-maintaining optical fiber having a cladding 125 μm in diameter even if the polarization-maintaining optical fiber has a small-diameter cladding of about 80 μm. The polarization-maintaining optical fiber includes a core, a pair of stress-applying parts provided radially outwardly with respect to the core, and a cladding which surrounds the core and the stress-applying parts. With a diameter D of the stress-applying parts between 21 μm and 32 μm, a distance R between the stress-applying parts between 6 μm and 17 μm, and a relative refractive index difference Δ between 0.3% to 0.5%, a sufficiently large mode field diameter (MFD) is obtained; thus splice loss can be reduced.

摘要： An image processing apparatus and method which can be selectively used in a variable mode and a fixed mode. In the variable mode, the quantizing values and thresholds for converting high valued image gradation into low valued image gradation can be changed so as to vary the surface gray levels of a printable image at a fixed laser gradation value. In the fixed mode, constant thresholds and quantizing values are used. The use of selectable operation modes enables easy printing operation with increased quality. Also, constant quality of printable images despite environmental changes may be realized by sensing and comparing currently read reference data with initially stored reference data and subsequently correcting quantizing values and thresholds in accordance with the compared result.
