  • Patent number: 5571594
    Abstract: In order to properly hold a number of miniaturized electronic component chips so that processing such as formation of external electrodes can be efficiently performed, a holder having an adhesive face to be stuck to first end surfaces of a number of electronic component chips for holding the electronic component chips is employed. The number of electronic component chips being held by the holder are dipped in electrode paste, so that external electrodes are formed on second end surfaces thereof. Then, an adhesive face of another holder having stronger adhesion than the adhesive face of the first holder is stuck to the electronic component chips, whereby the number of electronic component chips are simultaneously transferred to this holder. The first end surfaces are then also dipped in electrode paste to form external electrodes thereon.

  • Patent number: 5571596
    Abstract: An advanced, lightweight composite roofing shingle specifically designed to prevent hail damage and high wind uplift. The inventive laminate includes a conventional random fiberglass mat (20) used for shingle stability, sandwiched by an upper ply of Kevlar fabric (28) selected for high impact resistance, and a bottom ply of E-glass fabric (24) or similar type oriented for exceptional bending resistance. The fibrous materials are saturated or coated, and bonded with a suitable matrix such as roofing asphalt. Design flexibility, inherent in the novel roofing shingle concept, allows the material properties to be optimized for cost and performance based on weather requirements in various geographical regions of the country.

  • Patent number: 5436057
    Abstract: This invention relates to the discovery that the perceived softness of embossed tissue can be increased greatly while avoiding prior art nesting problems if a particular pattern is embossed into the tissue. This pattern combines relatively shallow stitchlike debossments with deeper more sharply defined signature debossments. The stitchlike debossments are rounded and arranged in wavy flowing intersecting lines. The signature debossments are arranged in regions framed by the intersecting wavy flowing lines.

  • Patent number: 5387456
    Abstract: There is provided a method for producing extruded, optical-quality, transparent panel units having integral flange members for joining to adjacent, similar panel units. The method includes the steps of extruding a substantially flat strip of suitable plastic material, calendering the extruded strip by pulling it in the still hot, pliable state through a calender, at least the central portion of the strip being smoothened to an optical-quality transparency and the marginal portions of the strip being provided with at least one sawtooth-like, continuous projection on at least one face of the marginal portions, controllably heating the strip at a limited zone on the one face to render the zone pliable, using bending rolls to bend the marginal portions at substantially a right angle, so as to turn them into flange members, the inside corners formed by the bending rolls between the central portion and the marginal portions being rounded, and finally, cutting the flanged panels to required length.

  • Patent number: 5366785
    Abstract: Disclosed is a cellulosic fibrous structure, particularly a consumer product such as toilet tissue, facial tissue or a paper towel. In a first embodiment, extending outwardly from each face of the cellulosic fibrous structure is a plurality of protuberances. The protuberances extend bilaterally outwardly from the plane of the cellulosic fibrous structure in both directions. The bilaterally extending protuberances increase the caliper and texture of the consumer product embodied in the cellulosic fibrous structure. In a second embodiment, the protuberances extend outwardly, and are induced by fluid embossing, rather than mechanical embossing. Also disclosed is a fluid embossing process for making such cellulosic fibrous structures.

  • Patent number: 5338595
    Abstract: Retroreflective appliques comprising a monolayer of retroreflective elements partially embedded in and protruding from the front surface of a binder layer and an optional layer of adhesive on the rear surface of the binder layer, wherein the binder layer, the adhesive layer, or both contain a metal-azo dye to camouflage the color of any exposed portions of said binder layer. Appliques comprising micropheres with aluminum reflectors as retroreflective elements and a black metal-azo dye in the binder layer will exhibit a pleasing silver appearance even after portions of the binder layer have been visibly exposed due to degradation of the aluminum reflectors, typically as a result of subjecting the applique to harsh laundering conditions.
