Abstract: A method of manufacturing a semiconductor device is presented. The device has: a gate terminal formed from polysilicon and covered by an insulation layer; and a plug extending through an insulation layer to provide an electrical connection to the gate trench. A metal layer is deposited to cover at least a portion of the insulation layer. The metal layer is then etched to remove the metal layer from above the plug.

Abstract: A Trench gate MOS field-effect transistor having a narrow, lightly doped, region extending from a channel accommodating region (3) of same conductivity type immediately adjacent the trench sidewall. The narrow region may be self-aligned to the top of a lower polysilicon shield region in the trench or may extend the complete depth of the trench. The narrow region advantageously relaxes the manufacturing tolerances, which otherwise require close alignment of the upper polysilicon trench gate to the body-drain junction.

Abstract: A beverage vending machine installation comprising a cabinet and a trolley unit, the cabinet defining a void in which, in use, the trolley unit can be positioned. The cabinet has an opening and at least one door moveable between open and closed positions. A trolley unit comprises at least one beverage vending machine. The trolley unit is moveable relative to the cabinet between an installed position and an uninstalled position. In the installed position the trolley unit is positioned within the void of the cabinet such that at least one door may be closed to allow operation of the vending machine installation. In the uninstalled position, the trolley unit is removed from the cabinet after opening at least one door to allow access to the trolley unit.

Abstract: A gas turbine powerplant for a V/STOL aircraft in which a vectorable exhaust nozzle at a forward part (eg. nose) of the aircraft selectably receives a supply of cold fan air through a duct leading from the fan through a passageway (28) coaxial with the engine axis and located within the hub of the fan (12), with the aid of controllable flaps and diverters (26, 30).

Abstract: The present invention is directed toward a self-decontaminating surface coating, which when cured has a partially hydrophobic surface. The coating comprises a polymeric coating resin which, when cured, is hydrophilic. The coating also comprises a biocide, a germinating agent, and a hydrophobic micro/nano particulate material. The coating is suitable for application to ceramics, metals, and polymer substrates. Articles coated with the coating of the present invention are resistant to spores.

Abstract: An ion selective membrane is provided where the membrane has improved ionic conductivity and mobility at elevated temperatures. The ion selective membrane includes a metallofullerene, where the metallofullerene may be a trimetasphere. The metallofullerene is incorporated into membrane materials that can withstand elevated temperatures, where the metallofullerene improves ionic conductivity and mobility therein.

Abstract: A method for detecting damage to an article caused by exposure to pressure is provided. The article is covered by a pressure sensitive material comprising at least one dye and at least one activator. As the article is exposed to pressure, the pressure sensitive material undergoes a color change in response to exposure to a pressure wherein the article is damaged.

Abstract: Processes and systems are provided whereby continuous polymeric microspheres are made by nebulizing a solventless initiated monomeric liquid (that is a liquid solution comprising a monomer and a polymerization initiator for the monomer) to form an aerosol of polymerization-initiated monomeric liquid droplets within a gas-filled reaction zone. The nebulized droplets of the monomeric liquid are allowed to fall under gravitational force through the reaction zone and to polymerize therewithin. The thus polymerized particles may thereafter be collected and removed from the reaction zone for further processing and/or use as may be desired.

Abstract: A system for monitoring the environment of an animal is disclosed generally comprising a video acquisition device worn by the animal and a monitoring device with which a remotely located user can monitor the animal's environment. The video acquisition device includes a camera for acquiring video, a transmitter for wirelessly transmitting the video to the monitoring device, and a rotation device for stabilizing the viewpoint of the camera regardless of the position of the animal. In certain embodiments, the camera is connected to an animal collar via a mount that has a rotating portion such that the camera rotates. In some embodiments, the rotating portion has a counterweight affixed thereto such that the camera rotates when the angle of inclination of the camera changes.

Abstract: Synthetic textile articles (e.g., filaments, fibers, yarns. fabrics and the like) and processes of making the same are provided which include flame-retardant SAP particles. The SAP particles are most preferably hydrated with an aqueous flame-retardant solution. In this regard, the flame-retardant solution may consist essentially of water alone or a water solution containing one or more water soluble inorganic flame retardants. When SAP particles are hydrated with an aqueous inorganic flame retardant solution, the SAP particles may thereafter be dried to remove substantially the water component. In such a manner, the inorganic flame retardant will remain as a dried residue physically entrained within the SAP particles. As such, the SAP particles serve as a physical matrix in which the inorganic flame retardant is homogenously dispersed. The SAP particles may then be chemically or physically affixed to the textile article in an amount sufficient to render the article flame-retardant.

Abstract: Disclosed are oxygen-scavenging polymer compositions having high transparency and low haze comprising immiscible blends of at least one polyester comprising 2,2,4,4-tetramethyl-1,3-cyclobutanediol, a copolyamide or a transamidized, homogeneous blend of a least two polyamides, and a metal catalyst. The components of the immiscible blend which have refractive indices which differ by about 0.006 to about ?0.0006. The small difference in the refractive indices enable the incorporation of regrind into the polymer composition to produce transparent shaped articles. The blends of the present invention are useful in producing shaped articles such as, for example, sheeting, films, tubes, bottles, preforms and profiles. These articles may have one or more layers and can exhibit improved excellent barrier properties and good melt processability while retaining excellent mechanical properties.
