  • Patent number: 7289687
    Abstract: 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 ?m in diameter even if the polarization-maintaining optical fiber has a small-diameter cladding of about 80 ?m. 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 ?m and 32 ?m, a distance R between the stress-applying parts between 6 ?m and 17 ?m, and a relative refractive index difference ? between 0.3% to 0.5%, a sufficiently large mode field diameter (MFD) is obtained; thus splice loss can be reduced.

  • Patent number: 6632298
    Abstract: 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.
