Abstract:
A beam coupler assembly for a fiber laser is disclosed. The assembly includes a housing having a sidewall with an interior surface, an exterior surface, a first end and a second end. A first seal extending from the interior surface of the tubular housing and dividing the housing into a first section and a second section is also provided. The first section and second section are environmentally isolated from one another. However, the first seal is substantially optically neutral. An input collimator unit received within the first end of the sidewall of the housing and into the first section and is releasably coupled thereto. An output collimator unit received within the second end of the sidewall of the housing and into the second section and is also releasably coupled thereto.
Abstract:
An assembly for distributing laser energy is provided that is formed using a compact rigid housing with a sealed beam path contained therein. The assembly employs a monolithic housing with modular collimator and mirror switching components installed therein to reduce its size while maintaining a sealed beam path thereby reducing the possibility of contamination of the beam path. Other than the optics and mirror, there are no elements of the distribution device contained within the beam path. In one embodiment, the assembly distributes incoming energy from a single source to one or more outputs. In another embodiment, the assembly operates as a beam combiner to direct energy from one or more sources to a single output.
Abstract:
An epoxy-free collimator assembly is configured with a ferrule and a lens operative to move within an outer case to a desired position therebetween. The collimator assembly further has an aligning component made from soft, malleable material which is capable of filling out the radial space between the ferrule and case so as to spatially fix the aligned fiber held in the ferrule and lens in the desirable position.
Abstract:
A box culvert and gasket assembly is provided that enables fluid-tight bell-and spigot joints to be formed between abutting ends of box culverts. The joints according to the assembly of the present invention can remain fluid-tight up to at least 13 psi of water pressure. The gasket is preferably a one-piece, endless rubber gasket that is applied over the end of a spigot that is rectangular in end elevation. The corners of the rectangular spigot are rounded to enable the gasket to extend continuously over the corner without the need for 45° cuts and splices. Preferably, the gasket is made from a single elongate gasket piece that is cut to size and that has ends that are bonded together via a butt vulcanization technique. A storm drain and sewer assembly and a method of forming a fluid-tight bell-and spigot joint are also provided.
Abstract:
A processing system for processing a substrate with a plasma comprises a processing chamber configured for containing a plasma and a substrate support. Electrodes are coupled to the substrate support and an RF power source is coupled to each of the electrodes for biasing the electrodes to create a DC bias on a substrate positioned on the supporting surface. Multiple voltage measurement circuits are electrically coupled to the RF power source and the electrodes to measure voltages at multiple points. A precursor determines the DC bias levels of the electrodes based on the multiple measurement points.
Abstract:
A processing system for processing a substrate comprises a process chamber having a top, a bottom, and a sidewall for defining a process space therein. The process chamber has an opening in the sidewall thereof for providing access to the process space. A plasma-generating assembly is coupled with the process chamber for creating a plasma within the process space. A substrate support assembly is configured for coupling with the process chamber to support a substrate within the process space. The substrate support assembly extends into the process space through the sidewall opening in the process chamber and seals the sidewall opening to generally isolate the process space from atmosphere.

Electrodes are coupled to the substrate support and an RF power source is coupled to each of the electrodes for biasing the electrodes to create a DC bias on a substrate positioned on the supporting surface. A first comparator having first and second inputs is electrically coupled to one of the electrodes with an isolating device being coupled between the first and second inputs to isolate the first input from the bias on the one electrode. The comparator has an output reflective of a voltage difference between the first and second inputs. A second comparator has a first input coupled to the first electrode and a second input coupled to the second electrode, and has an output reflective of a voltage difference between the first and second inputs resulting from the bias difference between the first and second electrodes.
Abstract:
Prefabricated concrete pipe encasements are disclosed for stabilizing underground conduit systems from movement caused by flotation, back filling or settling. In one embodiment, a sewer chimney includes a plastic riser connected between a tee-fitting in a sewer main and a cap block at a branch service line. At least one pipe encasement and a prefabricated concrete base encircles the riser for maintaining alignment with the tee-fitting. In other embodiments the pipe encasement encircles a generally horizontal pipe line.
