Fabrication of low defectivity electrochromic devices
ActiveUS20100243427A1High level of defectivityVacuum evaporation coatingSputtering coatingArchitectural glassGas phase
Prior electrochromic devices frequently suffer from high levels of defectivity. The defects may be manifest as pin holes or spots where the electrochromic transition is impaired. This is unacceptable for many applications such as electrochromic architectural glass. Improved electrochromic devices with low defectivity can be fabricated by depositing certain layered components of the electrochromic device in a single integrated deposition system. While these layers are being deposited and / or treated on a substrate, for example a glass window, the substrate never leaves a controlled ambient environment, for example a low pressure controlled atmosphere having very low levels of particles. These layers may be deposited using physical vapor deposition.

ActiveUS20100245973A1Improve equipment reliabilityImprove performanceVacuum evaporation coatingSputtering coatingElectricityLithium
Prior electrochromic devices frequently suffer from poor reliability and poor performance. Some of the difficulties result from inappropriate design and construction of the devices. In order to improve device reliability two layers of an electrochromic device, the counter electrode layer and the electrochromic layer, can each be fabricated to include defined amounts of lithium. Further, the electrochromic device may be subjected to a multistep thermochemical conditioning operation to improve performance. Additionally, careful choice of the materials and morphology of some components of the electrochromic device provides improvements in performance and reliability. In some devices, all layers of the device are entirely solid and inorganic.

Large gas turbine blades made from separate cast segments of superalloys are disclosed. The turbine blade is designed such that bond lines between adjacent segments are placed in low stress regions of the blade. The cast superalloy segments of the blades are aligned and fitted together with specified tolerances.

Method of making a product with improved material properties by moderate heat-treatment of a metal incorporating a dilute additive
InactiveUS6150186AStable mechanical propertiesImprove conductivitySemiconductor/solid-state device testing/measurementFinal product manufactureUltimate tensile strengthMechanical property
Deposition of metal in a preferred shape, including coatings on parts, or stand-alone materials, and subsequent heat treatment to provide improved mechanical properties. In particular, the method gives products with relatively high yield strength. The products often have relatively high elastic modulus, and are thermally stable, maintaining the high yield strength at temperatures considerably above 25 DEG C. This technique involves depositing a material in the presence of a selected additive, and then subjecting the deposited material to a moderate heat treatment. This moderate heat treatment differs from other commonly employed "stress relief" heat treatments in using lower temperatures and / or shorter times, preferably just enough to reorganize the material to the new, desired form. Coating a shape and heat treating provides a shaped deposit with improved material properties. Coating a shape with a portion connected to a base and a portion detached therefrom can provide a resilient, conductive contact useful for electronic applications.
