  • Patent number: 6259490
    Abstract: The present invention provides a liquid crystal display device having a position detecting function with a high sensitivity and a high resolution. The position detecting function comprises a position detecting electrically conductive film on a polarizer or a color filter glass substrate of the liquid crystal display device. The present invention also can suppress the undesired generation of an air gap between the polarizer and color filter glass substrate by using a polarizer that is smaller in size relative to the position detecting electrically conductive film.

  • Patent number: 6004661
    Abstract: An amorphous magnetic material possesses a composition essentially expressed by (Fe.sub.1-a-b N.sub.a M.sub.b).sub.100-x-y Si.sub.x B.sub.y (M denotes at least one kind of element selected from Mn, Cr, Co, Nb, V, Mo, Ta, W and Zr, 0.395.ltoreq.a.ltoreq.0.7, 0.ltoreq.b.ltoreq.0.21, 1-a-b<a, 6.ltoreq.x.ltoreq.18 at %, 10.ltoreq.y.ltoreq.18 at %, respectively). An amorphous magnetic material which has such a Ni rich Fe-Ni base possesses a Curie temperature T.sub.c of 473 to 573K, the maximum magnetic flux density B.sub.m of 0.5 to 0.9T. A ratio of residual magnetic flux density B.sub.r and the maximum magnetic flux density B.sub.m can be controlled according to a required characteristics, and, in the case of being used in a saturable core, is set at 0.60 or more. With an amorphous magnetic material of an inexpensive Fe-Ni base, magnetic characteristics applicable in a high frequency region, thermal stability, surface smoothness can be realized.

  • Patent number: 5298924
    Abstract: A multiple printing apparatus is capable of performing multiple printing, e.g. multi-stage printing, multi-color printing at extremely high speed by one sequence of feed in one direction. The multiple printing apparatus comprises a plurality of printing heads arranged in series along a direction of motion a printing object in relative movement between said printing heads and said printing object, and control means for selectively controlling each of the printing heads between operative position and inoperative position independently of the other printing heads.
