摘要： According to an aspect of the present invention, a method for laser soldering optical components is described. In that method, a first selected material is disposed on the components to facilitate the deposition of solder. Subsequently, solder is disposed on that material and the component is aligned. A laser beam is properly focused on the solder such that the solder melts and, when the laser beam is turned off, hardens, thereby fixing the component in the desired position.

摘要： A method for creating a protective layer over a surface of an object comprising aluminum and magnesium for use in a semiconductor processing system, which includes oxidizing the surface of the object using a plasma electrolytic oxidation process. The method also includes generating a halogen-comprising plasma by exciting a gas comprising a halogen. The method also includes exposing the oxidized surface to the halogen-comprising plasma or excited gas.

摘要： Disclosed are reinforced metal matrix composites and methods of shaping powder materials to form such composites. Articles of manufacture are formed in layers by a laser fabrication process. In the process, powder is melted and cooled to form successive layers of a discontinuously reinforced metal matrix. The matrix exhibits fine grain structure with enhanced properties over the unreinforced metal, including higher tensile modulus, higher strength, and greater hardness. In some preferred embodiments, an in-situ alloy powder, a powder metallurgy blend, or independently provided powders are reinforced with boron and/or carbon to form the composite.

摘要： An apparatus and methods for forming a toroidal plasma chamber includes metallic material, material forming process, heat treatment, anodization and a feature to form an ideal gas flow pattern in the plasma chamber. The gas passing through the plasma chamber that functions as a secondary wiring in a transformer will be dissociated when coupled with the current induced through a magnetic core by a primary wiring that is a semiconductor switching power source.
