IPC: B41J2/36
Filed: 1990-11-30
Abstract: The subject of the invention is a method of contrast control for a print medium produced by a thermal print head (1) of a printer of a data transmission system comprising a series of resistive elements arranged to be activated by the passage of a current provided by a card (3) linked to a source of power (4) and in order thus to heat. The activation times of the elements are adjusted at the start of printing for a print cycle of minimal duration. For longer cycles, the elements are reactivated (14) as soon as their temperature while falling reaches the initial temperature, by a series of holding microcycles with very short durations of activation. If the printer of a fax machine is concerned, to which the invention applies particularly well, contrast can thus be adjusted as a function of the nature of the quality of the thermosensitive paper and of the rendering which it is desired to obtain with respect to an original document. <IMAGE>

Abstract: The shaft (1) has, in the lateral proximal area, a cavity (15) delimited anteriorly and posteriorly by two wing-shaped tabs (14). In the cavity there is a spreading wedge (18), which is drawn into the cavity (15) in the direction of the shaft axis (6); the "drawing in" of the wedge (18) is effected by a tensioning rod (3), which in turn spreads open the jacket, subdivided by slots (2), of the distal circular cylinder. The spreading open of the tabs (14) produces, in the proximal area, a large surface of intimate contact between shaft (1) and bone, as a result of which, on the one hand, there is formation of stable bone tissue and, on the other hand, a "wide" distribution of the stresses as they pass further into the bone. <IMAGE>

Title: Ensemble d'actionnement combine des freins et des pignons
Inventor: COLLINS NICHOLAS JOHN
IPC: B62L3/02
Filed: 1990-02-12
Abstract: Un ensemble combiné monté sur le guidon d'une bicyclette comprend un levier (10) d'actionnement des pignons et un levier (12) d'actionnement des freins qui permettent de changer les vitesses et de passer sur un plus petit rapport en tirant le levier (10) de façon à l'éloigner du levier (12) et de passer sur un plus grand rapport en poussant le levier (10) de façon à le faire pénétrer dans l'arrière en forme de canal du levier (12). Lorsqu'on tire le levier (12) afin d'actionner les freins, le rapport n'est pas affecté. A cet effet, un mécanisme utilise l'axe (32) du levier d'actionnement des freins pour tourillonner un tambour d'enroulement (33) du câble d'actionnement des pignons, à dents (33C) commandées par le cliquet d'échappement (36). Le levier (10) d'actionnement des pignons pivote sur l'organe de support (31), qui lui pivote autour de 32. Lorsque l'on tire le levier (10) pour l'éloigner du levier (12), le levier (10) s'incline premièrement autour de l'axe de pivotement de son organe de support, puis une extrémité crénelée (27) du levier (10) vient en prise avec la périphérie (33A) du tambour;l'organe de support (31) et le levier (10) pivotent ensuite ensemble autour de l'axe (32), remontant le tambour d'une unité, manuellement équivalente à une dent. Lorsque l'on pousse le levier (10) pour le rapprocher du levier (12), il aboute sur 31d et incline le support (31) en sens inverse horaire, de sorte que la protubérance (34) libère le cliquet d'échappement (36) et permet au tambour denté (33) de tourner. Lorsque l'on tire le levier (12) vers l'intérieur, tout l'ensemble interne pivote autour de 32; le levier (10) reste toutefois dans une position inchangée par rapport aux dentelures (33A) du tambour et à l'aboutement (31D), de sorte qu'il ne se produit pas de changement de vitesse.

Abstract: Dans des installations comportant des places soumises au paiement d'une taxe, telles que des parkings à étages, le coefficient d'occupation instantané (N - n) est déterminé et la taxe (G) payée pour l'occupation des installations est automatiquement adaptée audit coefficient (N - n) et à la demande de la clientèle, selon une fonction (F) qui peut être introduite. Dans des installations de ce type, on cherche à obtenir, par le biais de l'adaptation automatique de la taxe, un coefficient prédéfini. On peut ainsi au moyen du coefficient instantané d'occupation ou de demande déterminé, faire varier dans le temps une fonction prédéfinie du coefficient d'occupation ou de demande, déterminée à partir de valeurs empiriques, en vue d'une gestion adaptée à un modèle.

Abstract: A control device suitable for the brake of a press for which high operation efficiency and precision in working are demanded, wherein displacements by a load of the stationary and movable tables are computed by only inputting bending work conditions including a target bending angle of a material plate to the device, an amount of adjustment in crowning is automatically computed from the above computation result, and further a position of the movable table after being displaced allowing for an amount of crowning adjustment is computed from the above two computation results. The material plate is bent with high precision of the basis of an adjustment amount of crowning and position of the displaced movable table thus obtained, whereby the plate is bent at the target angle without causing backward bending at the central portion.

Abstract: A piezoelectric actuator/sensor package and corresponding method for its fabrication, and a method of embedding a ceramic actuator/sensor in a laminated structural member, such as a graphite-epoxy laminate. A ceramic actuator/sensor, with lead wires first bonded to it, is encapsulated in a non-conductive fiber composite material, such as fiberglass cloth and epoxy, to form a package that is precured at a suitable temperature, typically room temperature. Encapsulation provides electrical insulation, good strain coupling, protection from mechanical damage, and reduction in thermal stresses, since the coefficient of thermal expansion of the encapsulating material is selected to be between those of the ceramic and the graphite-epoxy laminate. Graphite fibers may be added to the package to enhance voltage-strain performance. The package is embedded in the structural laminate and the composite structure is cured in a manner that minimizes thermally-induced stresses. Piezoelectric prestressing, during the embedment step, may be used to further reduce the effects of thermal stresses.
