  • Patent number: 5273828
    Abstract: In accordance with the present invention, there are provided coating liquids for forming conductive coatings, which comprise (i) a zirconium oxysalt, (ii) a conductive substance and, if necessary, (iii) at least one member selected from non-sedimentary silica dispersion and silicon alkoxide or its derivative. The coating liquids, when coated on substrates, form thereon transparent conductive coatings which are excellent in transparency, scratch resistance, permanence properties and adhesion to the substrates and, moreover, excellent in antistatic effect. In particular, when the coating liquids for forming conductive coatings mentioned above are coated by the spray method on appropriate substrates followed by drying and/or heating, there are obtained face-plates for display devices, which have excellent regular reflection reducing effect (non-glare) and antistatic effect.

  • Patent number: 5129131
    Abstract: In a method of and an apparatus for manufacturing a glass fiber mat, bundles of glass fibers shake down onto a conveyor unit arranged horizontally, to form a non-oriented fiber layer. The non-oriented fiber layer is dried by a drier. Bundles of uni-directional fibers are supplied onto the dried non-oriented fiber layer, by a bundle supply device, to laminate the uni-directional fiber layer onto the dried non-oriented fiber layer. At the laminating, the bundles of uni-directional fibers are guided in parallel relation to each other at regular intervals in a widthwise direction of the conveyor unit. The uni-directional and non-oriented fiber layers, which are laminated one upon the other, are supplied to a needler and are needled thereby, to form the glass fiber mat. The glass fiber mat is carried out by a delivery roller unit.
