  • Patent number: 8617667
    Abstract: Methods of leveling ink on substrates and apparatuses useful in printing are provided. An exemplary embodiment of the methods includes irradiating ink disposed on a surface of a porous substrate with radiation emitted by at least one radiant energy source. The radiation heats the ink to at least a viscosity threshold temperature of the ink to allow the ink to flow laterally on the surface to produce leveling of the ink. The ink is heated sufficiently rapidly that heat transfer from the ink to the substrate is sufficiently small during the leveling that ink at the substrate interface is cooled to a temperature below the viscosity threshold temperature thereby preventing any significant ink permeation into the substrate.

    Abstract: A method for manufacturing a magnetic recording medium of the present invention includes a magnetic layer forming step in which a drying process is performed. The drying process includes: a pre-heating stage in which a magnetic coating film is heated until the surface temperature of the magnetic coating film stops rising and reaches a substantially constant temperature; a constant rate drying stage that is performed after the pre-heating stage in which the surface temperature of the magnetic coating film is held substantially constant; and a falling rate drying stage that is performed after the constant rate drying stage in which the surface temperature of the magnetic coating film is increased to be higher than the surface temperature during the constant rate drying stage to harden the magnetic coating film. The constant rate drying period in which the constant rate drying stage is performed is 0.2 seconds or more.

  • Patent number: 8586131
    Abstract: The present invention generally relates to liquid films containing nanostructured materials, and, optionally, the use of this arrangement to organize nanostructures and to transfer the nanostructures to a surface. Liquid films containing nanostructures, such as nanoscale wires, can be formed in a gas such as air. By choosing an appropriate liquid, a liquid film can be expanded, for example to form a “bubble” having a diameter of at least about 5 cm or 10 cm. The size of the bubble can be controlled, in some cases, by controlling the viscosity of the liquid film. In some embodiments, the viscosity can be controlled to be between about 15 Pa s and about 25 Pa s, or controlled using a mixture of an aqueous liquid and an epoxy. In some cases, the film of liquid may be contacted with a surface, which can be used to transfer at least some of the nanostructures to the surface. In some cases, the nanostructures may be transferred as an orderly or aligned array.

  • Patent number: 8586126
    Abstract: Imprint lithography may comprise generating a fluid map, generating a fluid drop pattern, and applying a fluid to a substrate according to the fluid drop pattern. The fluid drop pattern may be generated using a stochastic process such as a Monte Carlo or structured experiment over the expected range of process variability for drop locations and drop volumes. Thus, variability in drop placement, volume, or both may be compensated for, resulting in surface features being substantially filled with the fluid during imprint.

  • Patent number: 8580344
    Abstract: This disclosure provides methods, devices and systems for using a stamp to enhance selectivity between surface layers of a substrate, and to facilitate functionalizing selected layers. An array of flat stamps may be used to concurrently stamp multiple regions of a substrate to transfer one or more substances to the topmost layer or layers of the substrate. If desired, the affected regions of the substrate may be isolated from each other through the use of a reactor plate that, when clamped to the substrate's surface, forms reaction wells in the area of stamping. The stamp area can, if desired, be configured for stamping the substrate after the reactor plate has been fitted, with the individual stamps sized and arranged in a manner that permits stamping within each reaction well.

  • Patent number: 8568822
    Abstract: An apparatus and method for incorporating discrete passive components into an integrated circuit package. A metal layer is formed over a surface of a substrate. A layer of photosensitive material is then formed over the metal layer. Using standard photolithographic processing, a pattern is formed with the photosensitive material to expose at least one region of the metal layer. The remaining photosensitive material protects the underlying metal during metal etching. The substrate is then subjected to a metal etching process to remove the metal that is not protected by the photosensitive material. The remaining photosensitive material is then removed from each remaining area of the metal layer. The discrete passive components can then be attached to the formed metal lands.
