  • Patent number: 7297219
    Abstract: A method for manufacturing a drum assembly for an internal drum-type imaging apparatus, and a drum assembly produced using the method. The drum assembly defines an imaging surface which is at least semi-cylindrical. A drum skin defines an imaging surface, and is releasably wrapped around a cylindrical mandrel, which has an axis. The mandrel and wrapped drum skin have a first radius. A drum includes more than one drum portion, and is attached to the drum skin over an at least semi-cylindrical interface. The drum has a radius slightly greater than the first radius, and the drum and attached drum skin cooperate to define a vacuum chamber. A fluid bearing is generated between the drum skin and the mandrel, preferably by pressurizing the vacuum chamber, in order to separate the drum skin from the mandrel. The drum and attached drum skin are then moved relative to the mandrel and in a direction parallel to the axis to remove the drum assembly from the mandrel.

  • Patent number: 7247356
    Abstract: A privacy screen for a display (e.g., a LCD) includes having a polarizing film and a birefringent film is described. The privacy screen transmits substantial amounts of light emanating from the display in an orthogonal (or near-orthogonal) direction while not transmitting substantial amounts of horizontal, non-orthogonal light emanating from the display. In this manner, a privacy effect results in that the display is viewable by someone only when that someone is essentially directly in front of the display.

  • Patent number: 7175893
    Abstract: A corrosion protection covering method for spliced regions of reinforcing steel is disclosed. The covering may include an outer, heat shrinkable layer and a flowable inner layer.

  • Patent number: 7169250
    Abstract: Nanofibrous articles can be manufactured by a process that includes preparation of a surface of a substrate to provide an adhesion mechanism for securing the nanofibers to the surface. The nanofibers can be dispersed in an area near the substrate for the purpose of being adhered to the surface. If an ordered arrangement of nanofibers is required, an electric field can be provided in the area where the nanofibers are dispersed to selectively control an ordering of the nanofibers as they are adhered to the surface by the adhesion mechanism.

  • Patent number: 7166365
    Abstract: An exterior finishing system including a bond-compatible composite membrane having a first self-adhesive material layer and a second rough fabric layer, and its use as an intermediate layer between a building structure substrate and exterior finishing materials is provided. Unlike conventional composite membranes, the bond-compatible composite membrane has a rough surface that allows bonding materials to adhere to it. Therefore, mechanical devices are not needed to attach the exterior finishing materials to the building structure.

  • Patent number: 7160601
    Abstract: A door jamb assembly for an entryway has a wooden jamb plate to which an extruded plastic brick mold and stop member is attached. The brick mold and stop member forms the raised stop of the jamb assembly also may form the brick mold thereof. The extruded plastic brick mold and stop member has a core made of economical cellular PVC plastic at least partially encased in a stabilizing layer of a plastic material, such as SAN, having a heat distortion temperature greater than that of the PVC plastic of the core. The stabilizing layer holds the core material in place and restrains it against distortion and shrinkage due to extreme temperatures, such as those found between a storm door and a door exposed to direct sunlight.

  • Patent number: 7150912
    Abstract: An inter-labium product capable of disintegration in water, fitted to the inter-labium part; and a surface-side sheet for inter-labium product that simultaneously realizes comfortability at wearing of the inter-labium product and capability of water disintegration such that the inter-labium product is disintegrated when thrown in flush water of water closet after use. The surface-side sheet for use in an inter-labium product fitted to the inter-labium part is comprised of hydrophilic fibers composed of single fibers and fibril fibers having fuzzes branched from the surface thereof, wherein at least some of the branched fuzzes link the single fibers and the fibril fibers to each other. Thus, not only can the wet tensile strength be increased but also inter-fibrous bonds are slowly decomposed in the presence of a large amount of water to thereby enable disposal of the inter-labium product in a flush toilet.

    Abstract: A preform for a fiber-reinforced composite material including a bent portion along a curved line for bending, a flange portion corresponding to an outer circumferential portion, and a semi-cylindrical portion formed by bending an inner circumferential portion along the curved line for bending located in a flat plane or a curved plane region. The preform is formed from a precursor having a predetermined extension. The outer circumferential portion corresponds to a first region where a first plurality of reinforced fibers is partially disposed in parallel along the curved line for bending. The inner circumferential portion corresponds to a second region constituted solely of a second plurality of reinforced fibers disposed throughout the entire area, so as to intersect the first plurality of reinforced fibers at a predetermined angle in the first region.

  • Patent number: 7135226
    Abstract: A manufacturing method for a composite fabric material is disclosed, which includes: holding a bundle of fibers under tension, the fiber being continuous filaments of carbon fibers, aramid fibers, or glass fibers, etc.; placing a layer of a matrix material over and under the fiber bundle, the matrix material being a thermoplastic adhesive material such as polyamide resins, thermoplastic polyurethane, or polyester, etc.; heating the matrix material to melt it and applying a pressure on the layers while the fiber bundle is under tension; and cooling the layers, whereby the fibers are locked in place by the adhesive. Composite material layers produced by the above steps may be laminated and further processed or formed as desired. The composite fabric materials manufactured by this method have superior tensile properties, compression properties, impact properties, and impact dispersion and propagation properties compared to composite fabric materials made with conventional methods.

  • Patent number: 7081294
    Abstract: A ceramic composite is able to whithstand temperatures in excess of 2200 F on a repeated basis without cracking due to thermal shock. The composite has a web of reinforcement fibers; and a matrix that substantially the web after the firing step. The matrix is formed around the web by impregnating the web with a sol containing alumina and, in some cases, rare earth oxides, and firing the composite after the impregnation. The web may be a three-dimensional orthogonal weave of the reinforcement fibers, where the fibers are a transitional phase alumina. The composite is essentially free of Group I and Group II metals and transition metal oxides. The composite may be used as a refractory brick or lining and may also be used as an insulatingmaterial due to its chemically non-reactive nature.
