摘要:
A process for producing a strip removes photoresist and extraneous deposits of polymer residue on the top surface and sidewalls of a post-metal etch wafer. The photoresist and residue are processed simultaneously by a chemical mechanism comprising reactive species derived from a microwave-excited fluorine-containing downstream gas, and a physical mechanism comprising ion bombardment that results from a radio frequency excited plasma and accompanying wafer self bias. A vacuum pump draws stripped photoresist and residues from the surface of the wafer and exhausts them from the chamber.

A conditioning shampoo containing an anionic cleansing surfactant, in an amount of about 5% to about 65% by weight, preferably about 5% to about 25% by weight, e.g., an ethoxylated (C.sub.12 -C.sub.22) alkyl sulfate and/or a long chain (C.sub.12 -C.sub.22) alkyl sulfonate, and a graft copolymer of a polyethylenimine and a silicone polymer in an amount of about 0.1% to about 20% by weight, preferably about 0.1% to about 10% by weight, is disclosed. The composition provides excellent foaming, conditioning, and phase stability.

An improved low-volume gas distribution assembly for a chemical downstream etch tool includes a focusing collar positioned within a process chamber and having a depending shroud in close proximity to a wafer chuck. An apertured gas delivery conduit rests on channels formed in slanted sides of a central tube of the focusing collar. The apertures in the gas delivery conduit are patterned and dimensioned to provide substantially uniform distribution of a process gas over the upper surface of the workpiece. The central tube is sealed with a cover plate and the process chamber is covered with a chamber lid.

Sliding joint system in a railway track allowing a great longitudinal excursion--particularly for suspension bridges--comprising, for each rail of the track, a first fixed rail (1) having an end tapered on the outwardly facing sides of the track, and a second rail (2) positioned next to the tapered surface of the first rail (1) and sliding along the same, while continuously extending beyond the tapered surface in an oblique direction, outwardly of the track, at an acute angle. The base flange of the second rail (2) is preferably of reduced width, equal to that of its head, so as to be more flexible. The deviation and sliding of the second rail (2) in respect of the first rail (1) are ensured by guides comprising: a first set of three guide rollers (3, 4, 5) meant to align the second rail (2) parallel to the main longitudinal axis of the track; a plurality of secondary rollers (6) with fixed vertical axes, positioned so as to face the tapered surface of the first rail (1); and pairs of coupled guide rollers (7), positioned at regular intervals along a first guide channel (8) of the second rail (2). The second rail (2) thus bends into and out of alignment with the first rail (1), upon thermal extension or contraction of the bridge, thereby to accommodate great variations in the length of the bridge whilst maintaining continuous tracks.
摘要:
A conditioning shampoo containing an anionic cleansing surfactant, in an amount of about 5% to about 65% by weight, preferably about 5% to about 25% by weight, e.g., (C.sub.12 -C.sub.22) alkyl sulfate, and/or a long chain (C.sub.12 -C.sub.22) partially or fully ethoxylated alkyl sulfate, and/or a long chain (C.sub.12 -C.sub.22) alkyl sulfonate, and a combination of cationic polymers comprising (1) a cationic (protonated) polyethyleneimine in an amount of about 0.1% to about 4% by weight, preferably about 0.1% to about 1% by weight, and (2) a cationic oil-soluble, water-dispersible, cross-linked quaternary acrylate/acrylamide copolymer (Polyquaternium 32), in an amount of about 0.1% to about 20% by weight of the composition, provides excellent foaming, conditioning and stability, without settling of water-insoluble materials due to anionic-cationic complexing. The composition preferably also includes one or more silicone conditioning agents, and has extended product stability, excellent overall conditioning to human hair, particularly superior wet and dry combing properties, and unexpectedly maintains very high levels of foam.

摘要:
An end-of-branch (EOB) module system for an audio signal distribution system having a wired trunk and a plurality of wired branches extending communicatively from such trunk, the EOB module system including: a plurality of EOB modules including one EOB module electronically coupled at each distal end of each branch and trunk of the audio signal distribution system, where each EOB module of the plurality of EOB modules has a unique address together forming a plurality of unique addresses; a test system able to send a test carrier signal encoded with any one unique address of the plurality of unique addresses at a time onto the trunk; and a switch within each EOB module, responsive to its unique address to place an end-of-line (EOL) load on its respective branch or trunk, and where power for operation of each EOB module is provided by rectification of the test signal.
摘要:
Targeted content associated with user information stored in a database within a network in communication with a user device is received along with program content. A determination by a scanning process is made at what position or at what time in the program content to include the targeted content. The program content and the targeted content are rendered, with the targeted content included at the determined position or time in the program content, for presentation to at least one user. This rendering may occur within a network or within a user device.
摘要:
Targeted content is delivered to and received by at least one user device based on user information stored locally at the user device. Program content and targeted content are received. The targeted content received is associated with user information stored locally on the user device, while the program content is broadcast to multiple users. A determination by a scanning process is made at what position or at what time in the program content to include the targeted content. The program content and the targeted content are rendered, with the targeted content included at the determined position or time in the program content, for presentation to the user.
摘要:
An apparatus and method providing a refrigeration servicing system that comprises a clean refrigerant source, a recovery circuit and a flushing circuit. The recovery circuit can be configured to recover refrigerant from a cooling system. After recovery cycle is completed, the flushing circuit that is coupled to the recovery circuit can flush clean refrigerant through the recovery circuit. A housing can be provided and configured to house the refrigerant source, the recovery circuit and the flushing circuit.
