  • Patent number: 6964793
    Abstract: A high-throughput lithography process for creating high-resolution patterns in a polymerizable composition using carefully controlled electric field followed by curing of the polymerizable composition is described. The process involves the use of a template that includes the desired patterns. This template is brought into close proximity to the polymerizable composition on the substrate. An external electric file is applied to the template-substrate interface while maintaining a uniform, carefully controlled gap between the template and substrate. This causes the polymerizable composition to be attracted to the raised portions of the template. By appropriately choosing the various process parameters such as the viscosity of the polymerizable composition, the magnitude of the electric field, and the distance between the template and substrate, the resolution of the structures formed in the liquid may be controlled to conform to that of the template.

  • Patent number: 6777025
    Abstract: A method for tensioning unrolled donor substrate to facilitate transfer of organic material to form a layer on the unrolled donor substrate, comprising the steps of: delivering of a portion of the unrolled donor substrate from a roll to a frame disposed in an organic coating chamber, such frame defining an aperture; engaging the unrolled donor substrate and tensioning such material using a first clamp assembly associated with the frame; coating the tensioned donor substrate with an organic layer in the organic coating chamber; and cutting the unrolled tensioned portion of donor substrate into a sheet before or after it has been coated with organic material.

  • Publication number: 20040154494
    Abstract: Novel, rapidly drying, low volatile organic compound (VOC), minimal dot gain coatings, (including lithographic ink and varnish systems) are herein described. These systems dry sufficiently rapidly, that their usage eliminates ink drying speed as the rate limiting factor in most lithographic printing applications. In addition to providing enhanced drying rates as compared with their conventional counterparts, the rapid drying, low/no VOC lithographic coating systems of the instant invention can provide the user with significant improvement in dried film rub resistance.

  • Patent number: 6743463
    Abstract: A method for electrostatic spray-coating a medical device having a tubular wall, such as a stent, having an inner surface, an outer surface and openings therein. The tubular wall is grounded or electrically charged, and an electrically charged conductive core wire is located axially through the center of the stent. An electrical potential is applied to the conductive core wire to impart an electrical charge to the conductive core wire. The tubular wall is exposed to an electrically charged coating formulation, and the electrically charged coating formulation is deposited onto a portion of the tubular wall to form a coating. The electrical potentials of the conductive core wire and tubular wall can be repeatedly alternated.

  • Patent number: 6740152
    Abstract: There are provided a recording liquid that produces high-quality images having a very high image density and water resistance, and can be discharged continuously and stably; a method for manufacturing such a solution; and a method for recording images by the use of such a solution. The recording liquid for ink printers according to the present invention contains a pigment and at least two kinds of fine resin particles, wherein the dispersion polarity of the pigment is the same as the dispersion polarity of each of the two or more kinds of fine resin particles. The method for manufacturing a recording liquid for ink printers has the step of mixing an aqueous dispersion of a pigment, and an aqueous dispersion of the two or more kinds of fine resin particles each having a polarity the same as the polarity of the aqueous dispersion of the pigment.
