Abstract: A program-controlled communication system is connected to a multiplicity of terminals (EG) which transfer stimuli to the communication system during connection signalling. The stimuli designate program modules (PM) which are allocated by a multitasking operating system (BS) with priority control to a system processor (SYPR) for processing. To avoid several high-priority stimuli output by a terminal (EG) unacceptably delaying the processing of the low-priority stimuli originating from other terminals (EG), a high-priority stimulus protection program module (AN) is provided which first registers incoming stimuli in stimulus stores (AZS) individually allocated to the terminals (EG). A low-priority arbitration program module (AR) in each case selects one of the stimulus stores (AZS) and, when finding a stimulus, initiates the processing of the program module (PM) designated by this stimulus. After the respective program module (PM) has been completely processed, the next stimulus store (AZS) is selected. <IMAGE>

Abstract: A holographic design is produced on a metallic article, made of gold or silver for example, by reproducing a micro-embossed image on the surface of this article directly by stamping at room temperature, this micro-embossing being such that it can be observed in white light in the form of a hologram. A stamping tool for implementing this method carries on the free stamping face a metallic film in the form of a negative of the desired holographic image, this metallic film being attached in such a way that it can be removed.

Abstract: Used in a Si single crystal pulling apparatus using the Czochralski method, to lower the concentration of oxygen in the Si single crystal without increasing the production cost and to make the concentration substantially even all over the Si single crystal. The crystal 36 is produced by disposing a straightening tube 40 concentrically with and above a quartz crucible 22, letting inert gas flow down through the tube, dipping a seed crystal in Si molten liquid 28 in the quartz crucible and then pulling the seed crystal up. The concentration of oxygen in the Si single crystal is adjusted by controlling the distance H between the surface of the Si molten liquid and the bottom end of the straightening tube in accordance with the pull-up length Y or the pull-up time from a certain growth point of the crystal.

Abstract: A communication method for a control device is described, consisting of a central unit (1) and a plurality of peripheral units (5) which are connected to one another and to the central unit via a data bus (3). Each peripheral unit is assigned an address which is stored in the peripheral unit. In order to activate a specific peripheral unit, the central unit transmits the address of the latter in the form of signal pulses to all the peripheral units, which compare the received addresses with the respective stored address. The peripheral unit which establishes correspondence between the received address and its stored address switches over to an activated state. To increase immunity to interference, it is provided that each peripheral unit, after its activation, sends a code signal which clearly identifies it back to the central unit. A particularly good access facility of the central unit to the peripheral units is produced through the use of a single, two-way data transmission line in that the central unit transmits its signals in the form of coded voltage pulses, while the peripheral units reply with coded current pulses. <IMAGE>

Abstract: A valve is in the form of a valve body (10) having a valve inlet (26), a valve outlet (28) and a valve seat (16) disposed between the inlet and the outlet. A valve closure member (12) is movable between a first, closed position in abutment with the valve seat (16) and a second, open position in which it is displaced from the valve seat (16). 
     A shaft (70) is pivotally mounted within the valve body (10) and one end is connected to an actuating handle (14), by means of which it is pivotable. An arm (54) is connected to the shaft (70) and to the valve closure member (12), whereby movement of the actuating handle (14) causes opening and closing of the valve. 
     The positioning of the pivoting portions of the valve and the spring within the valve body (i.e. in an aperture actually within the material forming the valve body) means that the only item other than the valve closure member in the path of material being discharged is the arm (54), and that when in the open position the valve closure member causes no constriction of the bore.

Abstract: L'invention concerne une feuille de couverture à transfert thermique comprenant une couche (2) de résine transparente et, si nécessaire, une couche (5) adhésive thermo-sensible, formées sur un film de base (1) entre lesquelles est interposée une couche de décollage (3), ainsi qu'un procédé de transfert thermique utilisant ladite feuille. La matière préférée pour la couche de résine transparente est une résine à durcissement par rayonnement ionisant, une résine modifiée par silicone et une résine contenant de la cire. Lorsque l'on pose ladite feuille sur la surface d'une image (7Y, 7M, 7C) et lorsqu'on la chauffe, la couche de résine transparente est transférée sur l'image afin de former une couche de protection de cette dernière, produisant ainsi un article sur lequel est formée une image, et lequel présente une durabilité, un effet brillant et un développement en couleur excellent, et ne s'enroule pas. Lorsque la majeure partie d'un agent de séparation est incorporée dans une couche de colorant à transfert thermique lors de la formation d'une image (7Y, 7M, 7C) par transfert par sublimation, il devient possible d'empêcher la couche de colorant de fusionner avec une couche de réception d'image, et d'améliorer l'adhérence de la couche de résine transparente sur la couche de réception d'image.

Abstract: Un amplificateur de détection (20) à une seule extrémité détecte si oui ou non une cellule de mémoire (24) se trouvant dans un réseau conduit du courant d'un conducteur (22) de ligne de bit auquel l'amplificateur de détection est connecté.

Le transistor d'égalisation (50) est sélectivement connecté entre le noeud (46) et la borne de sortie (56) lorsqu'il est conducteur, et établit au niveau du noeud une tension du point de polarisation de gain élevée entre les tensions supérieure et inférieure établies au niveau dudit noeud (46) par ledit premier étage.

Title: Dispositif d'alimentation pour convertisseurs, sans creation de distorsions dues aux harmoniques
Inventor: COURIER DE MERE HENRI EDOUARD
IPC: H02M1/42
Filed: 1990-07-19
Abstract: L'invention se rapporte à un dispositif économique servant à l'alimentation d'un convertisseur électronique à partir du secteur, sans que le courant prélevé sur le secteur soit affecté par une distorsion notable due aux harmoniques, quelle que soit la nature de la charge s'appliquant à la sortie du convertisseur. Un tel dispositif comprend un circuit tampon formé par au moins deux condensateurs (5a et 5b) chargés par le secteur, en série et déchargé chacun en parallèle à travers les bornes d'entrée (9a et 9b) du convertisseur (10). Dès que ce dernier se met à fonctionner, une fraction de l'énergie HF de sortie est rectifiée par le pont, qui ajoute son signal de sortie à celui délivré par le premier pont (3). Ainsi, la tension d'alimentation présente au niveau des bornes (9a et 9b) ne présente qu'un taux d'ondulation efficace réduit, tandis que le courant prélevé sur le secteur est essentiellement sinusoïdale en phase avec la tension, quelle que soit la nature de la charge s'appliquant à la sortie, résistive, inductive, capacitive ou non linéaire. Un tel dispositif peut s'appliquer à la plupart des convertisseurs électroniques utilisés comme ballasts, comme transformateurs, comme sources d'alimentation stabilisées, etc.

Abstract: This invention relates to a non-contact profile control apparatus which performs profile machining or digitizing on a work while profiling non-contactingly the shape of a model. The coordinates value of each apex of a very small square on the plane of a model (6) is obtained from the measured values at previous and current samplings from two non-contact range finders (5a, ab) and the direction of normal is obtained by use of the coordinates values of three predetermined apexes among them. Two rotary shafts (B1, C1) of a tracer head (4) are controlled in this direction. Accordingly, the measuring optical axes of the non-contact range finders are always kept perpendicular to the model plane and high precision range finding can be conducted.
