Patent EP-0349587-A1 (EP)
Inventor: STRATTON KENNETH L
IPC: G01S15/52
Filed: 1988-02-18
Abstract: Un système de référence de vitesse (10) utilise un décalage Doppler entre l'énergie d'onde transmise et l'énergie d'onde reçue pour déterminer la vitesse relative entre le système (10) et une surface (14) ou un élément. D'autres systèmes utilisant des décalages Doppler pour détecter la vitesse pâtissent d'une faible précision de mesure. La diaphonie entre des canaux des systèmes ayant des émetteurs et des récepteurs multiples produit des erreurs de mesure. De plus, un mouvement errant génère des erreurs de mesure étant donné que les capteurs ne peuvent différencier ce mouvement errant d'une vitesse en avant. Deux unités de détection (16, 16') dirigées l'une vers l'autre, et de préférence vers le même endroit sur la surface (14) éliminent effectivement le mouvement aléatoire du véhicule. En outre, des fréquences différentes de transmission provenant des deux unités de détection (16 16') réduisent la diaphonie entre les deux canaux. Les applications à des véhicules nécessitent un système pouvant réduire au minimum le mouvement errant et le bruit environnant.

Title: DISPOSITIFS A L'ARSENIURE DE GALLIUM (GaAs) AMELIORE A IMPLANTATION IONIQUE

IPC: H01L21/265
Filed: 1988-06-27
Abstract: Cette invention concerne un moyen permettant d'améliorer l'uniformité de la tension de seuil de MESFETs à l'arsémiure de gallium implantés ioniquement, par la co-implantation de deux espèces dopantes contrairement à la normale où l'on utilise qu'une seule espèce de dopant. On choisit les deux espèces de dopants de manière que les effets de l'activation des changements stoïchiométriques dans le substrat se produisent dans des sens opposés, ce qui réduit ou élimine ainsi les effets stoïchiométriques sur l'activation totale (et ainsi sur la tension de seuil des dispositifs).

Abstract: A corner guide comprises a pair of hinged panels (1,2) with an embedded duct (6) through which an optical fibre (7) 
can be threaded. The corner guide, for guiding an optical fibre (7) or the like around a corner (9) whose radius of curvature 
is less than a permissible minimum radius of curvature Rp for the fibre (7), guides the fibers (7) by means of the duct (6) 
along a path which extends into three dimensions. At the corner at the hinge between the panels (1,2), the duct (6) passes 
through an "x-y" plane containing the corner at an angle for instance of 70°. This enables an arrangement wherein the pro­
jection of the duct (6) onto the "x-y" plane includes a bend whose radius of curvature is less than Rp although the path it­
self does not include such a bend. The invention finds particular application in optical fibre installations in homes or of­
fices, wherever a fibre has to turn a corner, for instance at the corner of a room. Alternatively it finds application in 
equipment served by optical fibers which include for instance a hinged panel to which the fibers must extend.

Abstract: In the method and device for mixing and painting multiple-component plastic materials, in particular polyurethane, the individual basic colour pigments determining the shade are fed to the mixing chamber 2 separately, i.e. via separate paint lines 12 to 16, the amounts of the basic colour pigments being selected in such a way that the desired tone is produced. The formulation (mixing ratio) is thus fixed in advance and can be easily changed. The mixing of the basic colour pigments to give the desired shade does not take place until in the mixing chamber, so that the desired shade can be changed easily and quickly and without difficulties, in particular without cleaning problems.

Abstract: A grain chill roller (10) is manufactured by electroplating a layer of copper onto the surface of the roller. The layer of copper is then abrasively blasted with glass beads to produce surface features of a substantially uniform depth, and then the surface is abrasively blasted with small particles of silicon dioxide to modify the pattern of features formed by the previous blasting operation. The resulting surface is electroplated with a layer of bright nickel to level the down pattern of the surface without eliminating the down pattern. The roller is used in the manufacture of resin coated photographic paper, for example.

Abstract: Two pressure control valves have most components in common. One valve is a direct-acting sequence valve (10) and the other a vented counterbalance valve (7) with pilot assist (76). Both valves have a set opening pressure which is insensitive to secondary port pressure (14). Both valves may provide free reverse flow. The valves include a spring force reduction chamber (48) which receives hydraulic fluid at primary port pressure. Part of the opening force exerted at the primary port (12) is offset by pressure in the spring force reduction chamber (48) so that a spring (22) having a smaller spring constant may be used to resist opening force. This offsetting force may be readily modified by changing the diameter of the piston shaft (52) of the valve.

Abstract: Un système de composition linéaire d'images corrige la luminance et/ou la couleur non uniformes d'un fond coloré sans des inconvénients tels qu'un éclaircissement ou un obscurcissement des bords, des pertes de détails au niveau des bords et d'autres anomalies. Un signal de commande directement proportionnel à la luminance du fond coloré commande le niveau du décor de fond (18). Si le signal de commande n'est pas corrigé, le décor de fond contiendra toutes les variations de luminosité et de couleur du fond coloré. On développe des facteurs de correction en comparant (43, 43', 43'') les signaux vidéo RVB obtenus à partir du fond, avant la mise en place du sujet, avec les valeurs idéales RVB (47, 47', 47'') qui auraient été obtenues avec un fond parfait. Ces facteurs de correction permettent de corriger les signaux vidéo RVB lorsqu'on effectue la prise de vue après avoir mis le sujet en place. Le signal de commande, qui est nul dans la zone du sujet, peut être utilisé pour inhiber (56, 56', 56'') des corrections dans la zone du sujet.

IPC: G01R27/26

Abstract: The invention relates to a material humidity measuring device which operates in accordance with the dielectric measuring method. Due to the variation of the material humidity, the dielectric constant changes and thus the capacitance of the medium in which a measuring line is immersed or to which the latter is applied. Once the geometric data of the arrangement have become constant, there is a relation between the measuring transit time of the echo following an input signal and the material humidity to be determined, which relation is used for measuring purposes (echo method). In the device according to the invention, pulse-shaped exciting input signals at the measuring line are used which can be much longer than the transit time of the echo. At the input of the measuring line, excitation and echo become superimposed to form an overall voltage variation from which the arrival of the echo is recognised by threshold decision and after that the transit time of the echo is determined. The device according to the invention therefore manages with simple electronic and mechanical elements with wide tolerance, whilst retaining a high accuracy. <IMAGE>
