  • Patent number: 6340404
    Abstract: A antiglare layer 12 having a fine uneven surface is formed directly or through other layer(s) on a transparent substrate film 11, and a layer 13 having a low refractive index, which is lower than the refractive index of the antiglare layer 12, is formed thereon. The refractive index of the antiglare layer 12 is higher than the refractive index of a layer in contact with said antiglare layer 12 on its surface remote from the layer 13 having a low refractive index. An SiOx film may be used as the layer 13 having a low refractive index. The SiOx film per se has excellent gas barrier property and antifouling property as an optical functional membrane and is an optical functional material characterized by having excellent moistureproofness, scratch resistance, adhesion to a substrate, transparency, low refractive index, dye deterioration preventive property, and other properties.

  • Patent number: 5655237
    Abstract: In feather comforters and other comforters (primarily coverlet comforters) having a heat insulating material filled therein, to provide an air controlled comforter which makes it possible to obtain good sleep under comfortable sleeping conditions in terms of both temperature and humidity with the aid of warm or cool air, and which will not be moisturized itself so as to be free from the need of drying it each time after use. In a comforter in which a front cloth (1) and a rear cloth (2) is joined together at their peripheral edges to form a shape of bag, where a heat insulating material such as feather, wool, and cotton is filled in the bag, an air-permeable cloth (3) is joined with the rear cloth to define an air passage (4) ranging from hem to center part of the comforter. The air passage (4) is opened at the hem of the comforter, where an air opening (7) is provided for feeding warm or cool air.

  • Patent number: 5528781
    Abstract: In a cubic-quilt type feather quilt in which a plurality of compartments are defined by partitioning the interior of the quilt with partition cloths and feathers are filled inside, there is provided a feather quilt which functions to cover up the body, eliminating the possibility that outside air may flow in the bed due to clearances on the body side or when peripheral portions of the quilt are turned up, and thus which offers a comfortable sleep. Among the partition cloths to define the interior of the quilt, which are arranged in the central part of the quilt except at least its peripheral portions, the lateral partition cloths (3) are so formed that both right and left side portions are curved downward and the central part is floated up. Thus, the feather quilt is formed into such a dome shape that the quilt wholly covers up the body during sleep.
