Patent EP-0374232-A1 (EP)
Inventor: COCKRUM CHARLES A
IPC: H01L31/0216
Filed: 1989-03-13
Abstract: Un réseau de photodiodes est constitué d'un matériau du groupe II-VI, tel que HgCdTe, que l'on traite pour former une pluralité de jonctions de diodes. Ce réseau est fabriqué par un procédé consistant tout d'abord à réaliser une base absorbant le rayonnement (12), constituée d'un matériau du type p, à savoir Hg(1-x)CdxTe). Chacune des photodiodes est fabriquée par dépôt sur le substrat d'une couche (18) de matière de passivation à largeur de bande interdite plus grande, par dépôt d'une couche de photomasque (26) sur la couche de passivation et par élimination sélective de ladite couche de passivation à travers des ouvertures pratiquées à l'intérieur de la couche de photomasque. Un procédé d'élimination de cette couche de passivation (18) est le broyage ionique qui convertit également le matériau de substrat de type p sous-jacent en matériau de type n. La détérioration du réseau cristallin provoquée par le broyage ionique s'étend latéralement vers l'extérieur de sorte que la région de type n (14), et la jonction de diode p-n (16) qui lui est adjointe, sont disposées au-dessous de la couche de passivation (18). Dans une variante, le matériau de substrat est converti en un type opposé de conductivité par dépôt d'une couche de matériau source suivi d'un processus de diffusion.

Abstract: A method for purifying hydrofluoric acid, comprising the steps of filtering the hydrofluoric acid to remove particulates, passing the filtered acid through a cation exchange material and an anion exchange material to remove ions therefrom, at least periodically automatically monitoring the acid that has passed through at least a predetermined portion of the cation exchange material for a predetermined level of cationic impurity representative of actual or impending ionic breakthrough in the cation exchange material, at least periodically automatically monitoring the acid that has passed through at least a predetermined portion of the anion exchange material for a predetermined level of anionic impurity representative of ionic breakthrough in the anion exchange material, automatically interrupting flow of acid through the anionic or cationic exchange material at or prior to the time the breakthrough in such material occurs, while the flow is interrupted, regenerating the anionic or cationic exchange material, resuming the flow after the exchange material is regenerated, passing the acid from the cationic and anionic exchange materials through an ultrafilter and into a storage container, and monitoring the level of particulate impurities in acid that has passed through the anion and cation exchange materials and automatically passing the acid in the storage container through a filter when the level of particulates exceeds a predetermined level, until the particulates are below the predetermined level. Also disclosed is an apparatus for performing the foregoing process.

Abstract: In a burner (1) for stoichiometric combustion of liquid or gaseous fuels, which consists of an atomising nozzle (12), an air supply pipe (13) surrounding this, and a combustion chamber (20) which is formed by a burner pipe (11) and is provided with a screen (21) or with a baffle plate, there are made in the burner pipe (11) in the region facing the screen (21) a number of recesses (31) extending in the longitudinal direction of the burner pipe (11), through which waste gas (R) can flow into the combustion chamber (20) from the boiler space (2). There can moreover be provided in the front region of the burner pipe (11) a circumferential constriction (41). By means of this design, an optimum gasification and exceptionally good combustion of the air/fuel mixture is made possible with low operating noise, in particular even in the start phase, so that the content of nitrogen oxides in the waste gases can be reduced to a considerable extent during the entire duration of operation of the burner (1). <IMAGE>

Abstract: Internal combustion engine exhaust emission control system wherein an air pump (20) delivers air to the exhaust system (18), comprising an air flow control check valve (22), which is disposed between an air pump (20) and the exhaust system (18). The valving mechanism (34) is operated by a fluid actuator (40), comprising a vacuum chamber (50) connected to the engine intake system (14). A control mechanism (66) senses the pressure differential across valve seat (36) of valving mechanism (34) by means of two taps (68,70), one (68) of which is disposed between the air pump (20) and valving mechanism (34) and the other (70) of which is disposed between the valving mechanism (34) and the exhaust system (18). The pressure differential acts on a movable wall (78) to displace a valve (92), which opens a passageway (94) to bleed vacuum from the chamber (50) in order to close the valving mechanism (34) when exhaust back pressure is indicative of damaging backflow to the air pump (20).

Abstract: A brewing apparatus makes coffee by a drip method within a microwave oven. The brewing apparatus (10) includes a reservoir (14) for retaining a quantity of water for heating. The reservoir is positioned on and supported by a carafe (16). The carafe receives a quantity of brewed coffee therein. A basket (30) is positioned between the reservoir and the carafe for retaining coffee grounds. A U-shaped water transfer tube (40) is positioned within the reservoir having an inlet (48) adjacent to the bottom of the reservoir and an outlet (54) positioned externally of the reservoir. The application of microwave energy heats the water within the reservoir, initiating a pumping system that transfers the water from the reservoir (14) through the transfer tube (40). The water exhausted from the transfer tube is directed onto the coffee grounds within the basket (30). The brewed coffee, created by the contact between the heated water and the coffee grounds, passes from the basket into the carafe (16).

Abstract: The structure and organisation of a magnetic disk drive optimises the volumetric storage density within a device form factor by maximising the number of disks. The spindle and dual rotary actuators are supported at each end by a pair of support plates 22, 23 that are separated and supported by not only the spindle and actuator shafts, but also the voice coil motor core pieces and tie bars 52 which carry shock mounts. The head disk assembly 70 is shock mounted in the lower part 73 of a two part enclosure 72, 73 wherein the enclosure parts are aligned and separated by elastomer guides 77, 78 and the separation covered by a compliant tape 89 to complete the enclosure. Both actuators use a common servo surface while one actuator carries upwardly facing transducers and the other downwardly facing transducers so that each arm extending between disks 16 mounts only a single suspension-transducer assembly, thereby reducing the interdisk spacing. The enclosure occupies the entire vertical height of the form factor and the head-disk assembly occupies the full available height of the enclosure interior to accommodate as many disks as possible. Electrical components are excluded from the axial sides of the stack of disks.

Abstract: A computer system especially for solution of real time inference problems is disclosed. The system includes a systolic cellular processor which provides predictable and responsive real time operation and fine grain programmability. The system comprises a plurality of separate processor cells each having its own local memory, the cells running simultaneously and operative to execute their respective program instructions. A global memory is coupled via a global bus to the processor cells and provides data to the cells and stores data from the cells. The bus provides effectively simultaneous access of all cells to the global memory. A further feature of the system is a novel parallel programming language using English syntax and which provides synchronous and predictable binding of code to each cell. A graphic work station is provided as a user interface to provide visual access to each cell or to cell groups for ease of control. The system can also function to emulate large scale integrated circuit processors by reason of the fine grain programmed operation of the system.
