Abstract:

A process for removing organic electroluminescent residues from a substrate is described herein. The process includes the steps of providing a process gas comprising a fluorine-containing gas, optionally an oxygen-containing gas, and optionally an additive gas; activating the process gas in a remote chamber using at least one energy source to provide reactive species; and contacting the surface of the substrate with the reactive species to volatilize and remove the organic electroluminescent residue from the surface.

International Classification:

B23P 1304

US Classification:

29557

Abstract:

An improved shielding assembly for a circuit board. This assembly is formed by providing a substantially flat piece of metal that will be used to form a shield assembly. A template is obtained indicating locations of folds and tabs. The folds are at locations that will enable the tabs to be located in the holes on the circuit board. The template is used to etch grooves and to etch tabs. This can be used to form a shielding assembly.

International Classification:

H04N 710

US Classification:

348 6

Abstract:

An apparatus and method is provided for modulating and transmitting full-motion, television-quality color video signals along with digital data signals over a pair of ordinary unshielded twisted pair telephone wires without interfering with normal telephone data on the wires. A transmission method is disclosed involving frequency modulation of a baseband video signal and subsequent filtering to suppress an upper sideband corresponding to a color component of the original video signal. The filtered signal is received from the telephone wires at a difference location, filtered, demodulated and provided to a display device. Full-duplex operation over the same pair of wires is possible, such that two video signals may be simultaneously transmitted, each signal having an approximate bandwidth of 6 MHZ and shifted to a desirable noninterfering frequency location within the approximately 20 MHZ of usable bandwidth on the telephone wires. No pre-emphasis or de-emphasis is required to achieve good quality video transmission. The system has many applications including video distribution, conferencing, and communications.

International Classification:

F17C 500

US Classification:

423210

Abstract:

A method for delivering a gas having a proton affinity of less than 866 kJ/mol is disclosed. A support including at least one polymer sufficiently acidic to protonate the gas is contacted with the gas to protonate the gas. The protonated gas condenses to form a solid salt which is sorbed by the support. The gas is dispensed by deprotonating the sorbed solid salt to regenerate said gas. The at least one polymer of the support has a first Hammett acidity value greater than a second Hammett acidity value of a conjugate acid of the gas. Also provided is an apparatus for performing the method. The invention is especially useful for storing, transporting and delivering hazardous gases, such as arsine and phosphine. The polymer can be polymeric sulfonic acids, polymeric perfluoroalkylsulfonic acids, fluorinated sulfonic acid polymers, cross-linked sulfonated polystyrene-divinylbenzene macroreticular copolymers, carboxylic acid polymers, halogenated carboxylic acid functionalized polymers and mixtures thereof.

International Classification:

H05K 900

US Classification:

361424

Abstract:

An improved shielding assembly for a circuit board. The assembly includes a multi-layer circuit board, each layer of which has ground planes around the perimeter thereof. An edge plating on the circuit board connects the ground planes to one another. A number of tab holes are also in the board, and the shielding assembly is formed as a conductive box which is connected to the tab holes. A shielded area is formed within the shielding assembly. The shielding assembly is preferably formed by etching fold locations and folding, and by etching tabs to be formed.

Abstract:

A shielded print head assembly has a plurality of pieces that are self-aligned with one another. A base forms a ground plane, and includes a registry structure thereon which is preferably a pin extending above a top surface thereof. A circuit board is aligned by connecting inner surfaces of the circuit board around the pin to precisely locate a connector of the circuit board. A print head is located adjacent to the circuit board such that its connector is exactly adjacent to connector of the circuit board. An innerface connector is then used to connect between the circuit board connector and the print head connector, the interface connector being completely shielded by a cover. The interface connector is also held in self-alignment by the registry structure. The interface connector also has a top surface defining an insulation area, coupled against the cover which forms a ground plane. In this way, a shielded and self-aligned multi-piece print head is formed.
