  • Publication number: 20020048637
    Abstract: In a method for producing a magnetic recording medium, at least one magnetic layer is formed on a nonmagnetic support by coating. After all coating processes are completed, heat treatment is performed by heat-treating the support, which is undergone all the coating processes, at 95 to 140° C. for 1.0 to 10.0 seconds with continuously applying tension of from 1.0 to 4.0 kg/m to the support. Then, calendering process is performed at a temperature lower than the temperature of the heat treatment.

  • Patent number: 6329016
    Abstract: Lightweight, non-woven loop products for hook-and-loop fastening are disclosed, as are methods for making them and end products employing them. The products are non-woven webs of entangled fibers of substantial tenacity, the fibers forming both a sheet-form web body and hook-engageable, free-standing loops extending from the web body. The product is stretched and stabilized to produce spaced-apart loop clusters extending from a very thin web of taut fibers. In important cases a binder is added to stabilize the product in its stretched condition. An example of the loop product is produced by needle-punching a batt of staple fibers in multiple needle-punching operations, applying a foamed acrylic binder, and then stretching the needled batt and curing the binder with the batt stretched. Other forming techniques are disclosed and several novel articles and uses employing such loop products are described, such as for filters and fasteners.

  • Patent number: 6261634
    Abstract: When a thin film is formed on a flexible and filmy substrate by a vapor phase method, the substrate is prevented from warping to be caused by the internal stress remaining in the thin film. When the thin film is formed by the vapor phase method, the substrate is previously curved so that the stress acts in the direction canceling the internal stress remaining in the thin film to be formed prior to the filming. Accordingly, the stress of the curved substrate cancels out the stress remaining in the thin film formed on the substrate. The substrate having a thin film formed thereon is not warped, the stress in the interface between the thin film formed and the substrate is removed, and the thin film has no cracks to be caused by the stress.

  • Patent number: 6190476
    Abstract: Methods and apparatus are disclosed for producing gypsum board having at least one facing sheet, a core of cementitious material such as low density gypsum, and an intermediate layer of bond promoting material, such as higher density gypsum located therebetween. The apparatus includes a forming table having a transverse gap. The facing sheet travels along the forming table over the gap. A spreader roller has an outer surface extending partially into the gap to depress the facing sheet. The bond promoting material is deposited on the facing sheet upstream of the spreader roller and the spreader roller outer surface rotates in the same direction as the facing sheet to coat the facing sheet with the bond promoting material. The core layer material is deposited on the facing sheet downstream of the spreader roller on top of the bond promoting coating.

  • Patent number: 6159557
    Abstract: The process for producing pressure-sensitive adhesive tapes comprises the steps ofclamping a tube strip of a tube skin filled with a pressure-sensitive adhesive composition into an apparatus comprising a tubular appliance,passing the tube strip through the tubular appliance while opening the tube skin longitudinally to form a tape,separating the tape from the pressure-sensitive adhesive composition in such a way that some of the pressure-sensitive adhesive composition remains as a film on the tape,causing the separated pressure-sensitive adhesive composition to exit the apparatus by way of a discharge aperture, andwinding up the tape separated from the pressure-sensitive adhesive composition, with the pressure-sensitive adhesive film that has remained thereon, as a pressure-sensitive adhesive tape.

  • Patent number: 6096375
    Abstract: A reflective polarizer and a dichroic polarizer are combined to provide an improved optical polarizer. The dichroic and reflective polarizers are typically in close proximity to each other, and are preferably bonded together to eliminate the air gap between the polarizers. The combination of the two polarizers provides a high reflectivity of one polarization and high transmission for the perpendicular polarization from the reflective polarizer side of the combined polarizer, and high absorption and transmission for light of orthogonal polarization from the dichroic polarizer side. The combination also reduces iridescence as seen in transmission and when viewed in reflection from the dichroic polarizer side. The increased extinction ratio and low reflectivity of the optical polarizer allows use of a lower extinction ratio dichroic polarizer in applications requiring a given extinction ratio and high transmission.

  • Patent number: 6033723
    Abstract: Method and apparatus of coating a plurality of wet layers on an flexible elongated web, which is economical to build and easy to operate at high speeds, and an apparatus which can be used to manufacture multi-layer magnetic recording media of the highest quality. Such apparatus can employ a gravure coater while an extrusion die both smoothes the wet gravure layer to eliminate its pattern and simultaneously extrudes a second dispersion. That smoothing is provided by a face of the upstream lip, which face has a convex shape that allows the wet gravure layer to remain in contact with the upstream lip over a wrap angle .gamma. of at least two degrees, thus ensuring that the tensioned carrier web neither buckles in the cross-web direction nor experiences instabilities such as fluttering. The extruded layer is contacted by a smooth face of the downstream lip, and the coated carrier web exits the smooth face substantially tangentially at a sharp trailing corner.
