Title: Fabrication of semiconductor devices using phosphosilicate glasses
Inventor: FLEMING DEBRA A
IPC: H01L21/314
Filed: 1990-04-19
Granted: 1993-05-25
Abstract: Fabrication of Semiconductor Devices Using Phosphosilicate Glasses Abstract This invention is directed to a process of producing semiconductor i devices which involves deposition of protective glass layers by a particle beam technique from targets of phosphosilicate glass, as well as a process for production of such targets. The phosphosilicate glass containing 1-15 mole percent P2O5 is produced by a sol/gel technique which involves mixing of a fumed silica, with a surface area of 50-400 m2/g, preferably about 200 m2/g, with phosphoric acid andwater to form a sol with 20-55 wt. % silica, allowing it to gel, drying at ambient conditions, dehydrating at about 650°C in an atmosphere of an inert gas and chlorine and fluorine containing gases, heating up at a certain rate of from 100 to 180°C per hour to a peak sintering temperature below 1200°C and cooling so as to produce amorphous and transparent glass suitable for use as a target. The glass layers are highly advantageous as encapsulating layers, diffusion barrier layers, etc., especially for optical type and semiconductor devices. Production of the phosphosilicate glass by the sol/gel technique is highly advantageous over the conventional melting technique, being faster and much less expensive than the latter.

Title: Calibration cup for in vitro calibration of an oxygen saturation monitor and method of using same
Inventor: HIGGINS MICHAEL J
IPC: A61B5/00
Filed: 1990-05-11
Granted: 1996-09-10
Abstract: A calibration device is provided for in vitro calibration of a light guide.   The calibration device has a surface defining a cavity having an open end and a closed end opposite  the open end.  The opening is sized to receive the end portion of a light guide and a stop is provided near the closed end to prevent the light guide from contacting the inner surface of the closed end and to define an air gap between the end face of the light guide and the inner surface of the closed end.  The inner surface of the closed end  is  flat  and  perpendicular  to  the  longitudinal axis of the light guide.  The light guide directs light from the end face of the light guide across the gap and against the flat surface.   The  calibration  device  is  formed  of  a  suitable material,  such  as  polyethylene,  with  a  plurality  of  light scattering   particles  and  a  plurality  of  light  absorbing particles  having  neutral  density  filter  properties  uniformly distributed  therein.  Preferred  light absorbing particles that have the properties of a neutral density filter are carbon black.

Title: Support device for a picture tube component
Inventor: LEHNER HEINZ
IPC: H01J29/82
Filed: 1990-07-10
Granted: 2000-02-01
Abstract: A support device for a deflection unit (10) for a picture tube comprises pins (17) which in a longitudinal direction carry a thread (19) over part of their circumferences.      The pins run in guide bores, which are constructed so as to exhibit a recess of not less than the angular circumference of the thread. Each pin is at first so aligned in relation to the associated guide bore that the thread runs in the above-mentioned recess. In this position (after the deflection unit has been aligned), each pin is pushed until it contacts the tube cone (18.K). Then each pin is turned by 90°, thus ensuring that the above-mentioned thread cuts into the non-recessed wall of the guide bore. This ensures that each pin is fixed in position, and simultaneously, due to the lead of the thread, a tension is set between deflection unit and tube. The support device thus constructed has the advantage that the tension force between deflection unit and tube cone can be set precisely.      This avoids the optimum setting be lost due to different tension forces acting at the locations of the different support elements, as was the case when conventional support elements were used.

The harnesses are assembled in the second region by conveying the harnesses from one end of a conveyor to the other, by providing multiple work stations along the conveyor for manual work functions, by providing local supplies of wires at some work stations, by providing local supplies of connectors at some work stations, and by connecting some of the wires to some of the connectors at some of the work stations and integrating them into a wire harness. The local supplies of wires at some work stations axe provided by transporting the wires from the first region to the work stations. The conveyor is incremented periodically and the work functions at the various work stations are preselected to require substantially equal time to perform. The prepared wires for the harnesses are stored in channel trays and may be transported and supported on mobile carriages. The channel trays are U-shaped and may be oriented horizontally or vertically.

Abstract: An independently rotatably mounted container may be used, by agitating the contents thereof, in the performance of a multi-component reaction or assay, by selective rotation of said container in the presence of adjacently mounted component containers which are not rotated. Such a principle may be applied in suspending solid phases in, for example, automated immunoassay apparatus or in reconstituting freeze dried reagents.      Selective rotation has a number of advantages including gentleness to components and greater efficiency and reliability.

Title: Abrasion-resistant plates and method of fabricating same
Inventor: BRUNET PIERRE
IPC: D21B1/14
Filed: 1991-10-07
Granted: 1996-10-08
Abstract: The present invention relates to the manufacture of abrasion-proof plates. The abrasion-proof surface of the plate is composed of external face 5 of a layer of composite material based on spherical grains of melted tungsten carbide bonded in a soldering alloy. Grinding surface 5 has a smooth and even mould finish. The abrasion-proof layer contains a compact, regular and essentially uniform random distribution of tungsten carbide grains. Surface 5 is made by moulding: the tungsten carbide grains are inserted between the mould walls and core 2 of the part, and the soldering alloy is made to infiltrate between the powder grains, core 2 and the mould by increasing the temperature. The invention allows a significant increase in the abrasion resistance of grinding plates.

Granted: 2003-05-06
Abstract: For the low-temperature fractionation of air, espe-cially for the production of medium purity oxygen, the entire feed air (1) is compressed in a first compressor stage (2) and purified by adsorption (4). A first compo-nent stream (101) of the air is introduced into the high-pressure stage (7) of a two-stage rectifying column (6).      A second component stream is passed to the low-pressure stage (8), and 'this stream is separated, after adsorption (4), from the remaining feed air, heated against com-pressed feed air (3), and engine-expanded (13). The thus-produced work is utilized at least in part for the compression (2) of feed air.

Title: Device for conveying items of household linen
Inventor: JENSEN JORN MUNCH
IPC: D06F95/00
Filed: 1992-04-14
Granted: 2002-07-23
Abstract: The device for conveying items of household linen comprises two belt-shaped mechanisms, spaced apart from each other transversely to the conveying direction, each rotating along a guideway running essentially in the conveying direction. Attached to each of the belt-shaped mechanisms are holding elements. Items of household linen, which leave a first processing machine via an output conveyor, grasped by the holding elements, are conveyed by rotation of the belt-shaped mechanisms along a lifting segment to the point where they preferably hang freely and are easy to check. Satisfactory items of household linen run through a lowering segment, after the holding elements are turned back via a deflection roller, and are released to a further processing machine via an input conveyor. First, second and third control mechanisms provide for grasping and release of items of household linen. Thus items of household linen judged to be sub-standard can be removed from the processing line through activation of an ejection key which brings in the third control mechanisms via a control unit. With just one operator, items of household linen can be checked comfortably and practically without any fatigue.
