  • Patent number: 7078070
    Abstract: A method for fabricating an organic light emitting diode. The method forms an anode, an organic emitting layer and a cathode sequentially on a substrate. When the interface between the anode and the organic emitting layer is forming, the depositional rate of the anode on the substrate is decreasing and the deposition rate of the organic emitting layer on the substrate is increasing. When the interface between the organic emitting layer and the cathode is forming, the deposition rate of the organic emitting layer on the substrate is decreasing, and the deposition rate of the cathode on the substrate is increasing. This method can form a hazy heterojunction between the anode, the organic emitting layer and the cathode, thus forming an organic light emitting diode with a hazy heterojunction.

  • Patent number: 6960373
    Abstract: A solder jet apparatus is disclosed. The solder jet apparatus is a continuous mode solder jet that includes a blanking system and raster scan system. The use of the raster scan and blanking systems allows for a continuous stream of solder to be placed anywhere on the surface in any desired X-Y plane. This allows for greater accuracy as well as greater product throughput. Additionally, with the raster scan system, repairs to existing soldered surfaces can be quickly and easily performed using a map of the defects for directing the solder to the defects.

  • Patent number: 6936311
    Abstract: A method for creating a microarray of biomaterial uses a source of laser energy, a receiving substrate, and a target substrate. The target substrate comprises a laser-transparent support having a laser-facing surface and a support surface. The target substrate also comprises a composite material having a back surface in contact with the support surface and a front surface. The composite material comprises a mixture of the biomaterial to be deposited and a matrix material. The matrix material is a material that has the property that, when it is exposed to laser energy, it desorbs from the laser-transparent support. The source of laser energy is positioned in relation to the target substrate so that laser energy is directed through the laser-facing surface of the target substrate and through the laser-transparent support to strike the composite material at a defined target location. The receiving substrate is positioned in a spaced relation to the target substrate.

  • Patent number: 6933013
    Abstract: In order to allow application of any coating under a vacuum over a volatile gelatinous layer, such as polymer dispersed liquid crystal (PDLC) on an optical glass substrate with a transparent electrode, such as indium tin oxide (ITO) on its surface, a layer of an intermediate stress absorbing polymeric material is first applied to cover the volatile gelatinous layer to prevent evaporation and escape of volatiles, thereafter the coating is applied under a very high vacuum using for example a technique called Physical Vapor Deposition (PVD) or sputtering.

  • Patent number: 6905728
    Abstract: A new method for repairing turbine engine components is provided. The method utilizes a cold gas-dynamic spray technique to repair degradation on turbine blades, vanes and other components. In the cold gas-dynamic spray process particles at a temperature below their fusing temperature are accelerated and directed to a target surface on the turbine blade. When the particles strike the target surface, the kinetic energy of the particles is converted into plastic deformation of the particle, causing the particle to form a strong bond with the target surface. Post-spray processing is then performed to consolidate and homogenize the applied materials and restore integrity to the material properties in the repaired turbine component. Thus, the cold gas-dynamic spray process and post-spray processing can be employed to effectively repair degraded areas on gas turbine components.

  • Patent number: 6890588
    Abstract: A rotatable vacuum chamber receives an optical connector having an output face on which an optical gel is applied substantially without entrapped air. Opposite the output face is placed a gel dispenser with its opened nozzle pointing towards the output face. Uncured gel components contained in the dispenser are outgased prior to application of the gel on the output face while a vacuum is maintained in the chamber. Outgasing takes place at a first chamber orientation with the nozzle pointing upwards through which the outgasing air ventilates. The gel is applied at a second chamber orientation where the output face is horizontal and upwards pointing. Immediately following the gel application, the vacuum is unmade to prevent cooking of the mixed and uncured gel. A glass plate is then pressed against the applied fluid gel.

  • Patent number: 6881434
    Abstract: A process for improving the knot tensile strength of a braided suture while maintaining its first throw holding characteristics includes the steps of applying a biocompatible co-polymer to the braided suture and then heating the suture to a temperature above the flow point of the co-polymer. An outer coat is applied to the suture after the heating step. The suture may be scoured with a solvent before the co-polymer is applied or the co-polymer may be applied simultaneously with the scouring step. The co-polymer preferably comprises one or more lactones, more preferably, ?-caprolactone and glycolide. This process may be used with bioabsorbable sutures, such as those comprising filaments made of polyglycolide and polylactide.

  • Patent number: 6881440
    Abstract: The present invention relates to an improved protective composition and method. The preferred protective composition uses near equal amounts by weight or volume of a pre-polymer and curative; however up to three to one amounts of pre-polymer to curative are consistent with the composition and method of the invention. The mixture is applied by a portable spray apparatus using a mixing spray nozzle. For temporary protective coatings using the present invention a releasing agent is applied to the surface to be sealed. The present invention is ideally suited to protect bath tubs, whirlpools, shower stalls, shower pans, tile, marble, glass, metal, hardwoods, other smooth, non-porous surfaces, and the like. The resulting protective coat from the present invention is impenetrable to ladders, boots, sheet rock, mud, paint, dirt, metal pieces, rocks, gravel, sand, grime which might accompany work on or around the protected surface.

  • Patent number: 6881451
    Abstract: A process for producing a wear-resistant cylinder bearing surface includes rotating a laser about its longitudinal axis and simultaneously advancing the laser in a direction of the longitudinal axis which is coaxial with a cylinder of a crankcase. A powdery material is fed through the laser and a jet of the powdery material is directed toward the cylinder bearing surface. A laser beam is deflected to an impact region where the jet of the powdery material impinges on the cylinder bearing surface. The jet of the powdery material passes through the laser beam. The laser beam at least partially melts the impact region before the powdery material impinges on the impact region. A device for producing wear-resistant surfaces is also provided.

  • Patent number: 6878408
    Abstract: A sufficient number of pick-and-place devices (e.g., rolls) whose periods of contact with a substrate are equal or substantially equal to one another are used to form continuous void-free uniform coatings despite the occurrence of unintended or intended coating caliper surges, depressions or voids. The wetted surfaces of the devices contact and re-contact the coating at positions on the substrate that are different from one another. Extremely uniform and extremely thin coatings can be obtained at very high rates of speed. The pick-and-place devices also facilitate drying and reduce the sensitivity of drying ovens to coating caliper surges. Equipment containing the pick-and-place devices is simple to construct, set up and operate, and can easily be adjusted to alter coating thickness and compensate for coating caliper variations.
