Abstract: PROCESS FOR PRODUCING DEVICES CONTAINING           SILICON NITRIDE FILMS            Abstract Silicon nitride regions suitable for applications such as capping layers in integrated circuit fabrication are produced by an advantageous plasma deposition process. This process utilizes a combination of gases, including a silicon-containing gas, a nitrogen-containing gas, a fluorine-containing gas, and a hydrogen-containing gas. Silicon nitride having a low density of defect states and thus having excellent dielectric properties is produced.

IPC: F17C7/02
Filed: 1988-07-05
Granted: 1991-07-23
Abstract: Abstract of the Disclosure An apparatus and method for withdrawing cryogenic liquid from a vessel is disclosed.  The apparatus includes a tube for withdrawing the cryogenic liquid from the vessel,  a heating coil for gasifying the liquid that is withdrawn, and a heat exchanger,  consisting of an inner and outer tube, that is connected to the heating coil and immersed in the cryogenic Liquid.   In operation, cryogenic liquid is withdrawn through the withdrawal tube and passed through the heating coil, where it is vaporized.  The vapor that is produced  passes  through  the  outer  tube  of  the  heat exchanger, giving up heat to the cryogenic liquid in the vessel to thereby gasify a portion of it, to maintain head pressure within the vessel.  The vapor then passes through the  inner  tube  of  the  heat  exchanger,  and  exits  the apparatus.

Abstract: SOFTWARE MANAGEMENT STRUCTURE           Abstract of the Disclosure A software management structure is disclosed. A software application package is made up of several linked replaceable units (RU). Each RU is service-able without adversely effecting the other RUs.  The RUs are linked together in a hierarchical fashion in a series of levels.  In the preferred embodiment, five levels are used:  Application Group level (AG), Loadable Code Group level (LCG), Primary Functional Group level (PFG), Secondary Functional Group level (SFG), and Operational Code Group level (OCG).  The AG level defines a group of computer programs combined to perform a high level application tailor fit to meet the needs of the user.  The ECG level defines individual programs each created to perform a general task.  The PFG level refines the common programs defined in the LCG level to a more specific set of primary functions.  The SFG level refines the primary functions defined in the PFG level to an even more specialized set of secondary functions tailored closely to fit a specific user's needs. The OCG level contains the operational code needed to run the specialized user application package defined by the preceding four levels.     Each RU, regardless of level, contains self-identifying and maintenance information, and can also contain a list of hardware and software dependencies unique to that RU.  The self identifying, maintenance and dependency information contained in the RUs is also known as vital product data, or VPD.

Abstract: A self-diagnostic method for an on-board CTIS (10) for sensing system faults and/or vehicle conditions requiring system shut down.  There is conducted a variety of self diagnostic tests such as reading the pressure transducer when the main conduit is vented to atmosphere to determine if the transducer is generating impossible output signals, sensing initial tire pressure for a reading so low as to indicate a faulty pressure transducer or a catastrophic failure in the tires, seals and/or conduits, sensing failure of the wet tank switch to close under conditions sufficient to recharge the wet tank which indicates a compressor, tank or switch failure and/or sensing a trend of decreasing tire pressure during an inflation operation which indicates that leakage rates exceed inflation rates.  Upon detection of such a system fault or vehicle condition, the CTIS controller, preferably microprocessor based, will signal the vehicle operator of the condition and shutdown (i.e. close wheel end valves and discontinue all further pressure sensing/adjusting operation) the CTIS system.  Preferably, the vehicle operator will not be allowed to override the shutdown of the CTIS system.

Abstract: A method and apparatus are described, for extruding a thermosplastic protective jacket onto a steel pipe. The pipe is first coated with a layer of epoxy which is partly cured, and then is conveyed through a cross-head extruder where a layer of copolymer or other suitable adhesive is applied. The outermost thermoplastic jacket may be coextruded with the adhesive layer or laid down onto the pipe as it passes through a second cross-head extruder. Radial pressure is applied to a band of surface about the jacketed pipe which has been cooled to a stage such that the outer surface of the thermoplastic is hardened while the inner portion thereof remains above the softening temperature, thereby achieving good adhesion of the jacket to the pipe, without dislocating or blemishing the thermoplastic protective jacket.

Date Apr. 30, 1981.A method for producing decorative glass objects in which the decoration is created by blisters formed by air bubbles within solid glass and/or by a pattern on the outer surface of the glass. When producing glass objects provided with air bubbles by means of known methods the bubbles remain on the surface of the objects which then easily break. In addition, the bubbles are formed at random, which may make them appear as dim impurities. When, in accordance with the invention, molten glass is poured from above in the shape of a band into a hot mould, the molten glass is spread into the mould in layers between which microscopic air bubbles remain. As the glass surface cools, the air enclosed within the bubbles expands in the molten glass which, while cooling, leaves the bubbles as clear pearls inside the glass. As the molten glass is spread in layers towards the wall of the mould, a pattern is formed as the glass surface cools.
