  • Publication number: 20080213469
    Abstract: A method and apparatus for high density nanostructures is provided. The method and apparatus include Nano-compact optical disks, such as nano-compact disks (Nano-CDS). In one embodiment a 400 Gbit/in2 topographical bit density nano-CD with nearly three orders of magnitude higher than commercial CDS has been fabricated using nanoimprint lithography. The reading and wearing of such Nano-CDS have been studied using scanning proximal probe methods. Using a tapping mode, a Nano-CD was read 1000 times without any detectable degradation of the disk or the silicon probe tip. In accelerated wear tests with a contact mode, the damage threshold was found to be 19/N. This indicates that in a tapping mode, both the Nano-CD and silicon probe tip should have a lifetime that is at least four orders of magnitude longer than that at the damage threshold.

  • Patent number: 7402265
    Abstract: Techniques for generating a stable, force-resisting positive or negative representation of a shape. A state-changeable mixture includes uniform, generally ordered, closely-spaced solid bodies and a liquid carrier medium, with the liquid filling any voids or interstices between the bodies and excluding air or gas bubbles from the mixture. Within the mixture, the solid bodies can be caused to transition from a near-liquid or fluent condition of mobility to a stable, force-resisting condition. To create mobility, a small excess quantity or transition liquid is introduced to create a fluent condition by providing a slight clearance between the bodies which permits the gently-forced introduction of at least two simultaneous slip planes between ordered bulk masses of the bodies at any point in the mixture. Transition to the stable condition is caused by extraction of the transition liquid, removing the clearance between bodies and causing them to make stable, consolidated contact.

  • Patent number: 7220376
    Abstract: A negative impression of an anatomical portion of a person is captured by forcing the anatomical portion into impression foam to collapse the impression foam into the negative impression. The impression foam has a crush characteristic of approximately constant resistance force over a relatively wide predetermined range of collapse distances. The negative impression is obtained by collapsing the impression foam within the range of constant-force collapse distances, thereby creating the negative impression under conditions which reflect an equally-loaded anatomical portion. A cushion support contour created from the equally-loaded negative impression is beneficial in more appropriately supporting the anatomical portion. The present invention is particularly useful in fabricating wheelchair seat cushions.

  • Patent number: 6878323
    Abstract: A stay-in-place method of manufacturing a composite form that is used to provide a strong and durable concrete structure. The form includes a composite shell having an inner wall surface defining an enclosure into which concrete may be poured and allowed to harden. The composite shell may be made of one or several layers of fabric having a resin matrix impregnated therein. The concrete hardens to form a concrete core within the enclosure and a liner is affixed to the inner wall surface of the composite shell to protect the composite shell from alkalinity in the concrete core. The liner includes at least one sheet of a water-impermeable material to protect the concrete core from water and other corrosive elements. The fabric layers are selected such that the fibers elongate as the concrete is poured into the enclosure due to a weight of the concrete and partially shrink back to compensate for shrinkage of the concrete as the concrete dries to form the concrete core.

  • Patent number: 6818139
    Abstract: In a method for forming a micro-pattern on a substrate (200), polymer material having a solvent is coated on the substrate, thereby forming a polymer film on the substrate. Then, a mold (204) having a predetermined shape is compressed into the polymer film (202) on the substrate by employing a predetermined compression technique to entail a plastic deformation of the polymer film, thereby patterning the polymer film. This compression procedure is performed at a room temperature, e.g., of about 10 to about 30° C. In the present invention, before the mold (204) is pressed into the polymer film (202), a free volume in the polymer film is previously increased so that a pressure applied on the polymer material needed to plastically deform the polymer film is reduced. Thereafter, etching is performed on the substrate through the use of the patterned polymer film as an etching mask, thereby forming a micro-pattern on the substrate.

  • Publication number: 20040222554
    Abstract: A mold for relatively uniform heating and molding of a work material to form a workpiece using a microwave oven, includes upper and lower mold members and a sidewall mold member. The mold members are formed from materials selected to have an approximately equal effective thermosensitivity. The effective thermosensitivity of work material is its dissipation factor divided by the product of its dielectric constant, density and specific heat. The effective thermosensitivity of the material of mold layer of each mold member is its dissipation factor divided by the product of its dielectric constant, density, and specific heat and multiplied by the fraction of the mass of its mold layer divided by the total mass of this mold member. A metal sleeve is formed on an inner surface of the sidewall mold member with microwave absorbing material formed on the outside thereof and inner surfaces of the end mold members may also be coated with metal or other highly thermally conductive and wear resistant material.

  • Publication number: 20040201131
    Abstract: A method and system are shown for protecting the threaded ends of tubular goods such as oil field tubulars from physical damage and corrosion due to environmental factors. A thread protector is formed of a polymeric body having cylindrical wall portions which engage the threaded ends of the tubular goods. Instead of relying upon a separate thread compound or corrosion inhibitor applied to the exposed threads, the polymeric body has incorporated therein a corrosion inhibiting compound, which is integrally molded within the polymeric body as a part of the manufacturing process used to mold the polymeric body. The method also allows used end caps to be recycled into the corrosion resistant end caps of the invention.

  • Patent number: 6800234
    Abstract: This disclosure relates to a method for making a polymeric article mold, a method for making a polymeric article with that mold, and improved surface topography features for a polymeric article. A prototype article is formed and then coated with a thin conductive layer. The coated prototype article is then electroformed until nickel plated to a sufficient depth to define a nickel plating tool. After the prototype article has been removed from the mold face of the nickel tool, the tool can be used as a mold for forming finished polymeric articles which replicate the original prototype article. The use of fine topography features such as a dense upstanding stem array on the surface of the prototype article facilitates accurate and complete electroforming by increased surface area presentation. The disclosure also presents improvements to microreplicated surface structures such as stem arrays.

  • Patent number: 6780352
    Abstract: Techniques for generating a stable, force-resisting positive or negative representation of a shape. A state-changeable mixture includes uniform, generally ordered, closely-spaced solid bodies and a liquid carrier medium of relatively similar density, with the liquid medium filling any voids or interstices between the bodies and excluding air or gas bubbles from the mixture. Within the mixture, the solid bodies can be caused to transition from a near-liquid or fluent condition of mobility to a stable, force-resisting condition through introduction and then extraction of a slight excess quantity of the carrier medium. To create mobility, this excess quantity or transition liquid is introduced to create a fluent condition by providing a slight clearance between the bodies which permits the gently-forced introduction of at least two simultaneous slip planes between ordered bulk masses of the bodies at any point in the mixture.
