  • 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: 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: 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.
