摘要:
A supply source for delivery of a CO-containing dopant gas composition is provided. The composition includes a controlled amount of a diluent gas mixture such as xenon and hydrogen, which are each provided at controlled volumetric ratios to ensure optimal carbon ion implantation performance. The composition can be packaged as a dopant gas kit consisting of a CO-containing supply source and a diluent mixture supply source. Alternatively, the composition can be pre-mixed and introduced from a single source that can be actuated in response to a sub-atmospheric condition achieved along the discharge flow path to allow a controlled flow of the dopant mixture from the interior volume of the device into an ion source apparatus.

A container for transporting and storing hazardous materials such as Chlorine includes a cylindrical body having end caps. The end caps are welded to the body to form a pressure vessel. The end caps have a peripheral edge that is recessed with respect to the ends of the body to protect the weld against damage from impact. The configuration of the juxtaposed components forms a lap joint that can be affixed together by a fillet weld.
摘要:
A method of coating an interior of a gas storage container, where the method includes supplying a chemical vapor precursor to the storage container, and forming a metal coating on the interior surface of the container, where the coating is formed from the chemical vapor precursor. Also, a gas storage container that includes a gas storage vessel with an interior surface that has a liner formed on the interior surface of the storage vessel. The liner may include tungsten metal with a purity of about 99%, by weight, or more. Additionally, a system for making a metal lined gas storage container that may include a chemical vapor precursor generator, and a precursor injection assembly for transporting the precursor into a gas storage vessel. The system may also include an exhaust outlet for removing gaseous deposition products from the gas storage vessel.

The present invention provides a compressed gas cylinder that is capable of storing a compressed fluid at high pressures. The cylinder of the present invention includes a body terminating in an inwardly domed cap. The dome included in the cap of the compressed gas cylinder of the present invention is formed such that the material near the tip of the dome is relatively thinner than the material near the base of the dome. The tip of the dome, therefore, creates a pierce region in the cap that can be pierced through the application of a relatively low pressure.
摘要:
A liquefiable gas pressure cylinder (10) and method for making the same with the cylinder including a cylindrical shell (100) and heads (200) fusion welded at opposites ends of the shell. The side ends where the heads (200) are joined to the shell are crimped radially inward to each end to form chimes (150). The welds are 100 % radiographed and heat treated. The heads (150) are dished to have a domed center portion (210) which has a profile and thickness so that the domed center portions (210) will reverse before any other part of the cylinder is stressed beyond a yield limit for such part.
摘要:
A fluid storage and dispensing system (10) comprising a vessel (12) for holding a fluid (17) at a desired pressure. The vessel has a pressure regulator (26) set at a predetermined pressure. The regulator may be interiorly or exteriorly positioned, single-staged or multi-staged, and is associated with a port of the vessel. A dispensing assembly, e.g., including a flow control means such as a valve (20), is arranged in gas/vapor flow communication with the regulator (26), whereby the opening of the valve effects dispensing of gas/vapor from the vessel (12). The fluid in the vessel may be constituted by a liquid that is confined in the vessel at a pressure in excess of its liquefaction pressure at prevailing temperature conditions, e.g., ambient (room) temperature.
