Patent EP-0782226-A1 (EP)
Inventor: DAUTREMONT-SMITH WILLIAM
IPC: H01S5/12
Filed: 1996-12-05
Abstract: Embodiments of the invention include a distributed feedback (DFB) laser is made with a spatially graded optical coupling (κ) between its diffraction grating and its active layer by means of selective area epitaxial growth of the epitaxial layer from which the grating is formed. More specifically, the epitaxial layer is formed on a major surface of a semiconductor substrate on which a mask, such as a silicon dioxide mask, has been formed. The mask has a pair of segments spaced apart by a fixed distance, the segments having spatially variable widths. Advantageously the epitaxial layer has a refractive index that is different from that of the substrate at the operating wavelength of the laser. The epitaxial layer is then etched into stripes. In this way the heights of the resulting grating stripes will be spatially variable, and so will the coupling κ between the grating and the active layer. In this way, the properties of the optical output of the laser can be adjusted. Advantageously also, the spacer layer and the substrate have the same refractive indices at the operating wavelength of the laser, whereby accurate control over the depth of the etching is not required.

Abstract: Accidental penetration of the underside of a nuclear reactor pressure vessel during core meltdown is detected and monitored by measuring the temp. at a plurality of points (14) within an area (8) of the floor of the concrete containment well which lies vertically below the lower end dome of the vessel. An assembly for so measuring the temps. comprises an array of optical fibres (10), whose free end portions span area (8) and are provided with spaced Bragg gratings (14) designed to reflect different characteristic wavelengths from the wide wavelength band of light directed along the fibres. These characteristic wavelengths vary with the temps. of the corresponding gratings, so that analysing the various wavelengths reflected back along the different fibres produces a temp. map of area (8).

IPC: H01S5/026
Filed: 1996-09-05
Abstract: The separation of the electrodes (17, 18, 19) is obtained by reactive ion beam etching and chemical attack and deep etching produces a separation resistance of 2 kiloohm. Protons are introduced in the sides of the strip forming the active region (13, 14) and the absorbent region to reduce the current loss and the stray capacitance. Semi-insulating InP layers may be located either side of the strip. The absorbent region (16) comprises multiple quantum wells. It is controlled by an inverted voltage (-V) which almost instantaneously modifies the rate of absorption and the laser is polarised in such a way that there is a laser effect when the voltage is zero. Selective epitaxy on the surface is used to manufacture the absorption region.

Title: Hand-held applicator with force limiting clutch
Inventor: RODRIGUEZ ALEX JR
IPC: B05C17/01
Filed: 1996-01-11
Abstract: An applicator (10, 10a) has a ratchet mechanism for dispensing material from a single or multiple barrel container (58). The ratchet mechanism includes a clutch (28, 34) that substantially prevents movement of a plunger (18, 18a) of the applicator (10, 10a) whenever a resistance to plunger movement is greater than a certain value. As a consequence, bursting of the container (58), or damage to components of the applicator (10, 10a), is substantially avoided.

Abstract: Procédé servant à optimiser l'efficacité de l'énergie d'un système utilisé dans le bâtiment, tel qu'un système d'éclairage, et comprenant une pluralité de dispositifs consommant de l'énergie, tels que des sources de lumière. Ce procédé consiste à définir un ensemble de paramètres pour le système de bâtiment et à utiliser, de façon spécifique, une technique de programmation linéaire, en prenant en considération l'ensemble de paramètres, afin de produire des données de sortie d'attribution d'énergie satisfaisant une contrainte de consommation de totalité d'énergie, à savoir que la totalité de l'énergie attribuée au système de bâtiment ne dépasse pas un niveau cible de consommation d'énergie et représentant une attribution optimale d'énergie à chacun desdits dispositifs consommant de l'énergie. De manière générale, le problème d'optimisation d'énergie est traduit en problème de programmation linéaire au moyen de la formulation d'un ensemble de contraintes d'attribution d'énergie au système, de la conversion desdites contraintes en un ensemble d'équations de contrainte et en une fonction de coût, de la conversion de ces équations de contrainte en un ensemble d'équations linéaires simultanées et de la résolution de l'ensemble d'équations linéaires simultanées, de manière à minimiser la fonction de coût, afin de produire les données de sortie d'attribution d'énergie, ce qui se présentera, de préférence, sous la forme d'un niveau maximum de brillance pour chaque source de lumière. Ces étapes sont, de préférence, mises en application dans un logiciel informatique, de préférence, chargé dans un contrôleur central programmable d'un système intelligent de commande d'éclairage ou d'un système de bâtiment réagissant aux données de sortie d'attribution d'énergie, afin de régler automatiquement le niveau de consommation d'énergie de chacun des dispositifs consommant de l'énergie. L'énergie disponible restante après avoir répondu aux niveaux minima de besoin d'énergie pour chaque local, est, de préférence, attribuée au moins partiellement sur la base du niveau désigné de priorité pour chaque local et/ou de l'efficacité énergétique des dispositifs consommant de l'énergie.

Abstract: The miniature racing course solves the problem of automatic devices for racing games, primarily in public places and against advance payment. The racing course (1) is equipped with at least one, two, three or more racing lanes (4) for model cars (6) which are operated by remote controls (10) and with optical measuring instruments (7) at the start and at the finish and with at least one parking box (3) for parking model cars (6). The racing course (1) can have one or more side lanes (2), with one, two, three or more side tracks (5). However, it can also be constructed without the side lane, on which the construction of the parking box (3) depends. If the side lane (2) does exist, the parking box (3) is placed directly on it and if the side lane does not exist, the parking box (3) is constructed above and below the racing course (1). In this case the racing course is separated in this place so that the legs of the dropping parts (1') are connected with the track section (13) linked to the bottom of the supporting safety bottom (12). The miniature racing course is activated by means of an automatic activating device (8) against advance payment. The intermediate results, the number of circles covered and the time spent as well as the final results with the appropriate order of competitors are visible on an information board (9).
