Patent EP-0273927-A1 (EP)
Inventor: GARLICK GEORGE F J
IPC: B23K26/02

Abstract: Appareil pour protéger les éléments fragiles des systèmes de détection optique contre les effets nocifs de radiation laser puissante non souhaitée. Une pellicule réfléchissante à couche mince (14) est placée dans la trajectoire lumineuse d'un télescope de détection. La lumière incidente (10) est focalisée par une combinaison d'éléments optiques (12) sur la surface réfléchissante (28) du limiteur de puissance laser à pellicule (14). La lumière réfléchie (10) est ensuite transmise par d'autres éléments optiques (16) pour faire une image sur un réseau de détecteur (18). Au cas où un signal dont la force ne peut être acceptée par le détecteur entre dans l'orifice de détection avec la lumière incidente (10), l'énergie focalisée à la surface de la pellicule (28) fera disparaître la pellicule optique et métallique, brûlera la pellicule en laissant un trou, et la lumière de haute intensité (11) sera déviée du réseau détecteur et sera absorbée par la décharge du faisceau (20). Un compteur de puissance agencé dans la décharge du faisceau indique le moment quand le laser ne présente plus de danger et donne l'ordre aux mécanismes de giration (15a et 15b) de tourner le réflecteur à pellicule vers une nouvelle position à laquelle le détecteur peut reprendre son fonctionnement normal. La pellicule réfléchissante de la protection contre les dangers dus au laser est munie d'une pellicule support de carbone située en aval du revêtement réfléchissant. Ce revêtement possède une capacité d'absorption de lumière laser uniforme et à large bande et peut protéger un détecteur contre un ordre varié de dangers potentiels. Le système de protection des détecteurs décrit par l'invention offre un temps de réponse extrêmement court, une protection à large bande, ainsi qu'une marge de sécurité sans égale.

Abstract: Bei einem Verfahren zur Endpunkt-Kontrolle von durch im Plasma aktivierte Ionen, Radikale und/oder neutrale Teilchen bewirkten Ätzprozessen (sogenanntes Trockenätzen) an elektrisch isolierenden Schichten wird der Endpunkt des Materialabtrages mit Hilfe eines auf dem beweglichen Substrathalter (7, 17) im Rezipienten (22) befindlichen Referenzsubstrates von definierter Probengeometrie durch Messung des elektrischen Widerstandes dadurch bestimmt, daß der Spannungsabfall UM1 eines in bekannten Zeitabständen in die unter der abzutragenden Schicht liegende elektrisch leitende Schicht eingeprägten bekannten konstanten Stromes IM1 gemessen wird und die Messung solange fortgesetzt wird, bis der durch das Plasma in die leitende Schicht zusätzlich injizierte Strom Iinj den Spannungsabfall verändert. Die Meßdaten werden berührungsfrei durch elektromagnetische Strahlung im Pulscode-Modulationsverfahren übertragen, wobei ein telemetrisches Meßsystem (18) verwendet wird, welches als unabhängige Einheit an den beweglichen Substrathalter (7, 17) montiert ist. Auf diese Weise kann eine lokale Endpunktkontrolle im Plasma durchgeführt werden und gegebenenfalls der Ätzprozeß über die Ätzrate mit Hilfe eines Prozeßrechners (30) gesteuert werden. Durch die direkt an der abzutragenden Schicht (1, 11) durchgeführten Messungen entfallen die bis jetzt am Plasma vorgenommenen, schwierig durchzuführenden Untersuchungen. Das Verfahren wird verwendet bei der Herstellung von Strukturen von dielektrischen Schichten im subµm-Bereich.

Abstract: A vehicular headlight, in particular an automobile head­light, including a reflector (1) having a reflecting surface, is capable of illuminating a flat target surface to be illuminated with a desired light distribution by optimal utilization of the light source of the headlight. Therefore the optically effective surface of the headlight is characterized by point asymmetry in substantially all planes cutting said reflecting surface. This can be realized by using a method for producing said optical surface comprising the steps of: 
    mathematically representing said surface by creating a spline from bivariate tensor product of polynomials; deriving mathematical data in computer input format from said mathemati­cal representation; and inputting said data to a computer for controlling an apparatus by which the mathematical representa­tion of said optical surface is reproduced in physical form. 
     Such splines, in turn, are represented and subsequently altered, preferably either by the so-called Bezier method or by the so-called Basis-spline method.

Abstract: A phoneme estimator (12) in a speech-recognition system (10) includes trigger circuitry (18, 22) for identifying the segments of speech that should be analyzed for phoneme content. Speech-element processors (24, 26, and 28) calculate the likelihoods that currently received speech contains individual phonemes, but they operate only when the trigger circuitry identifies such segments. The computation-intensive processing for determining phoneme likelihoods is thus performed on only a small subset of the received speech segments. The accuracy of the speech-­element processors (24, 26, and 28) is enhanced because these processors operate by recognition of patterns not only in elements of the data-reduced representations of the received speech but also in higher-ordered products of those elements; that is, these circuits employ non-linear modeling for phoneme identification.

Abstract: An insulated-gate, field-effect transistor and a double-sided, junction-gate field-effect transistor are connected in series on the same chip to form a high-voltage MOS transistor. An extended drain region is formed on top of a substrate of opposite conductivity-type material. A top layer of material having a conductivity-type opposite that of the extended drain and similar to that of the substrate is provided by ion-implantation through the same mask window as the extended drain region. This top layer covers only an intermediate portion of the extended drain which has ends contacting a silicon dioxide layer thereabove. The top layer is either connected to the substrate or left floating. Current flow through the extended drain region can be controlled by the substrate and the top layer, which act as gates providing field-effects for pinching off the extended drain region therebetween. A complementary pair of such high-voltage MOS transistors having opposite conductivity-type are provided on the same chip.

Abstract: A linear unit which consists of a basic body (10) which is used for guidance and has running rails (11) on which a carriage (12) can be moved between two end stops by means of a toothed belt (26) fastened to the underside with its two ends. The toothed belt is run over the drive pinion driven by a motor and over a return pinion (18). To tension the toothed belt (26), one pinion, preferably the return pinion (18), is constructed so as to be displaceable with its spindle (25). The toothed belt can be tensioned by tightening tensioning elements (22, 24) which act on the pinion. Here, a device (15) is provided for limiting the tensioning distance in order to set a defined tension of the toothed belt (26). This results in a particularly high positional accuracy of the carriage (12), and the service life of the toothed belt is improved at the same time. <IMAGE>

Abstract: A method for preparing an active metallocene-­alumoxane catalyst  in situ  during polymerization. A metallocene-alyminum alkyl catalyst complex is activated during olefin polymerization by feeding wet monomer to a reaction vessel. Water entrained in the monomer at 100-10,000 ppm reacts with the aluminum alkyl in the catalyst complex to form an alumoxane, activating the resulting metallocene-alumoxane catalyst complex and initiating polymerization of the olefin monomer. The method is applied to batch and continuous olefin polymerization in gas or solution phase. The catalyst complex may be homogeneous or supported.

Abstract: In NMR pulse experiments transverse magnetization is ex­cited by irradiating the nuclear spin system with a two pulse sequence of a first RF chirp pulse and a second RF chirp pulse, generated after a defocusing time interval τ . The pulse duration of the second chirp pulse is half the duration of the first pulse, and the amplitude of the second chirp pulse is approximately three times the ampli­tude of the first chirp pulse. The first pulse being a 90°-pulse, the second pulse being a 180°-pulse, a refocu­sing of the magnetization vectors occurs at a time τ′ = τ + τ 180°  after elapse of the second chirp pulse, and acquisition of the resulting echo signal is started at peak of the echo.
