摘要:
A method and apparatus for depositing a material layer to treat and condition a substrate, such as a fuel cell part, is described. The method includes depositing a hydrophilic material layer on a portion of the surface of the substrate in a process chamber from a mixture of precursors of the hydrophilic material layer. In addition, the method includes reducing a fluid contact angle of the substrate surface. The hydrophilic material layer comprises a wet etch rate of less than about 0.03 Å/min in the presence of about 10 ppm of hydrofluoric acid in water. The material layer can be used to condition various parts of a fuel cell useful in applications to generate electricity.

In certain embodiments, an apparatus for providing a fixed impedance transformation network for driving a plasma chamber includes a pre-match network adapted to couple between an Active RF match network and a plasma chamber load associated with the plasma chamber. The pre-match network includes (1) a first capacitive element; (2) an inductive element connected in parallel with the first capacitive element to form a parallel circuit that presents a stepped-up impedance to an output of the Active RF match network such that a voltage required to drive the plasma chamber load is reduced; and (3) a second capacitive element coupled to the parallel circuit and adapted to couple to the plasma chamber load. The second capacitive element reduces or cancels at least in part a reactance corresponding to an inductance associated with the plasma chamber load. Numerous other aspects are provided.

An apparatus and method for shaping profiles of a large-area PECVD electrode is provided. A plasma-enhanced CVD chamber for processing a large-area substrate is first provided. The chamber includes a lower electrode that supports a large area substrate. The lower electrode is shaped to selectively conform the supported substrate in a selected orientation under operating conditions. The orientation may be either planar or nonplanar. The substrate complies with the shape of the electrode so the substrate is substantially parallel to an upper electrode in the chamber, and/or to a gas diffusion plate in the chamber. The lower electrode comprises a substrate support fabricated from a material of insufficient strength to support itself at operating temperatures and pressure in the chamber. The shape of the substrate support is adjusted by modifying the dimensions and/or planarity of a supporting base structure, and/or by appropriately varying the thickness of the substrate support.
摘要:
A method and apparatus for sealing a puncture or incision formed percutaneously in tissue separating two internal portions of the body of a living being with an anchor, a sealing plug and a filament connecting the anchor and sealing plug. The method and apparatus provide for automatic tamping and/or cinching of the sealing plug when the apparatus is withdrawn from the puncture site. The automatic tamping and/or cinching is facilitated by transducing a motive force generated by the withdrawal of the apparatus into a tamping and/or cinching force.
摘要:
A support ring is intended for mounting on a wheel rim inside a tire, in order to support the tire in the event of a loss of inflation pressure. The support ring has a base intended to fit around the wheel rim, a cap, and an annular body joining the base and the cap together. Within the base of the ring, to control the expansion characteristics of the support ring, is a metal support. The metal support has a mesh configuration.
摘要:
Human chemokine polypeptides and DNA (RNA) encoding such chemokine polypeptides and a procedure for producing such polypeptides by recombinant techniques is disclosed. Also disclosed are methods for utilizing such chemokine polypeptides for the treatment of leukemia, tumors, chronic infections, autoimmune disease, fibrotic disorders, wound healing and psoriasis. Antagonists against such chemokine polypeptides and their use as a therapeutic to treat rheumatoid arthritis, autoimmune and chronic inflammatory and infective diseases, allergic reactions, prostaglandin-independent fever and bone marrow failure are also disclosed.
摘要:
Generally, a method and apparatus for retaining polishing material is provided. In one embodiment, the apparatus includes a platen having a top surface, a plurality of channels and one or more vacuum ports. The top surface is adapted to support the polishing material. The plurality of channels are formed in a polishing area of the top surface. The vacuum ports are disposed in the platen and at least one port is in communication with at least one of the channels. Upon application of a vacuum to the ports, the channels remove fluids under the polishing material while securing the polishing material to the top surface.
摘要:
A method for reducing emissions of a kiln including a feed end, the method includes operating the kiln and spraying a slurry inside the kiln at least five feet from the feed end. Additionally, the kiln includes a substantially tubular body including a bore therethrough. The body has a clinker end, a heat portion, and a feed portion. The kiln further includes a plurality of chains mounted within the bore at the feed portion, a heat source in flow communication with the heat portion, and a spray nozzle mounted in the feed portion away from the feed end.
