Patent EP-0472162-A1 (EP)
Inventor: SUGIYAMA YASUNARI
IPC: G11B5/33
Filed: 1991-08-20
Abstract: A magnetic head comprises a substrate (2), a soft magnetic thin film (1), whose magnetic permeability varies according to the intensity of an external magnetic field applied thereto, formed over the surface of the substrate, means (10a-10e) for supplying a high-frequency current to the soft magnetic thin film, and means (5) for applying a bias magnetic field to the soft magnetic thin film. The magnetic permeability of the soft magnetic thin film varies according to the variation of the intensity of the external magnetic field and hence the potential difference between the opposite ends of the soft magnetic thin film with respect to the direction of flow of the high-frequency current varies accordingly. The variation of the potential difference is detected (11) for magnetic signal reading. The soft magnetic thin film is formed of a material having a large magnetic permeability, such as amorphous CO₇₅Ta₁₁Zr₁₄.

Abstract: The process gases are passed into a steady-speed fluidised bed designed as an annular trough and fitted with cooling elements. Fluidising gas is passed into the fluidised bed through the inflow tray of the trough. The process gas is introduced through the central orifice of the fluidised bed. Cooled solid flows out of the fluidised bed over the inner rim of the trough into the process gas stream and is carried along by the latter into the dust chamber above the surface of the fluidised bed. The solid deposited in the dust chamber drops back into the annular fluidised bed, and the cooled gas containing the residual solid is passed into a gas cooler fitted with cooling surfaces. The gas emanating from the upper part of the gas cooler is passed into a dust precipitator, and the precipitated solid is recycled into the steady-speed fluidised bed.

Abstract: Un système d'aspiration des fumées présentes dans une zone de travail, par exemple à proximité d'un pistolet de soudage, comporte une gaine d'évacuation articulée (14) munie dans sa partie initiale d'une hotte d'aspiration de fumées (13). Un émetteur de signaux (6) est monté sur l'outil de travail (34), et trois détecteurs (38, 40, 42) sont montés sur la hotte (12), un à l'avant et les deux autres de part et d'autre de la hotte pour former un triangle. Un premier moteur (24) ouvre et ferme l'angle entre les parties avant et arrière de la gaine d'évacuation; un deuxième moteur (28) déplace la partie arrière de la gaine en arrière et en avant dans le même plan vertical que celui dans lequel se déplacent les parties avant et arrière de la gaine d'évacuation sous l'effet du premier moteur (24), et un troisième moteur (30) fait tourner l'ensemble tout entier en suivant un arc de cercle. Les détecteurs sont montés de manière à produire des signaux d'erreur de triangulation. De cette manière, le mouvement relatif de l'émetteur par rapport aux détecteurs, ainsi que la direction de ce mouvement, peuvent être déterminés. Des circuits de transformation de signaux produisent des signaux pour commander le mouvement nécessaire d'un moteur donné ou d'une combinaison de moteurs (24, 28, 30), dans la direction requise pour neutraliser les signaux d'erreur de triangulation. De cette façon, la hotte d'aspiration de fumées (12) est rapprochée de l'outil de travail (34).

Abstract: Un appareil d'essai à grande vitesse mémorise les données correspondant aux première et dernière adresses de chaque boucle d'essai dans une antémémoire à grande vitesse. Dans la majorité des adresses d'essai, des données sont transférées d'une mémoire à au moins deux registres de décalage et l'antémémoire n'est pas accessible. Les signaux de sortie des registres de décalage sont imbriqués dans un multiplexeur pour fournir deux bits de données d'essai pour chaque cycle d'horloge de l'appareil d'essai. Des circuits de commande décodent les bits associés à chaque adresse de données et commandent la présentation de données provenant de la mémoire et de l'antémémoire aux registres de décalage. L'utilisation de l'antémémoire permet d'obtenir une sortie continue de données d'essai du multiplexeur au cours des répétitions d'une boucle et lorsque de nouvelles boucles d'essai sont introduites, sans intervalles entre les données, que les données se terminent par une limite d'adresse au pas.

Title: Power line communication system.
Inventor: STEVENS CARLILE R
IPC: H04B3/54
Filed: 1991-09-27
Abstract: Data is transmitted on a power line (15) as a momentary interruption of the power at or near the zero crossing of the current. The interruption is preferably a small fraction of the period of the frequency of the power line. The data is transmitted only to those devices in series circuit with the transmitter. The transmitter (13) combines 60 Hz and 120 Hz clock signals with data from a shift register to interrupt current in a predetermined pattern, in which an interruption of both the positive going and negative going zero crossings define a logic "1" and the absence of interruptions is a logic "0". A data prefix identifies succeeding bits as data. The receiver (17) produces a pulse width modulated signal in response to the data.

Abstract: Une cible (40), dont l'épaisseur varie radialement en fonction de la quantité de matière devant être pulvérisée, est supportée dans un logement (42) dans la chambre (10) d'un appareil de revêtement par pulvérisation. Une boucle fermée constituée d'une bande (80) formant un aimant permanent ou un électro-aimant, de préférence un aimant permanent flexible, est fixée à un porte-aimant (55) qui tourne derière le logement de la cible autour de l'axe central de la cible. Des parties de l'aimant se trouvent près du bord de la cible et des parties sont près du centre de la cible, mais non sur le centre de la cible. Un pôle de l'aimant fait face au bord de la cible et l'autre pôle fait face à l'axe central de sorte que le champ magnétique de l'aimant enferme le bord de la cible dans un tunnel magnétique qui piège un plasma sur la cible. Des aimants localisés (90, 91, 92) traversant le centre à partir de la bande, supportent le plasma à proximité du centre pour créer une pulvérisation au centre de la cible. D'autres aimants localisés (95, 96, 97, 98) contigus à la bande aident à affiner le champ magnétique de façon à créer la répartition voulue de la pulvérisation. Dans un espace hermétique (44) situé derrière le logement de la cible et en contact thermique avec ce logement, se trouve le support duquel dépassent les aimants pour faciliter le flux de liquide traversant la surface arrière du logement de la cible pour refroidir celle-ci pendant que ledit support tourne.

Filed: 1992-05-13
Abstract: The application relates to a method and an arrangement for detecting and identifying impurities on water surfaces by determining the transmission properties of a water surface and of the gas phase due to water vapour above the water surface. The object of the invention is therefore to provide a method and an arrangement which enable continuous monitoring of a water surface. It is intended to avoid triggering a false alarm by identifying the interference. This object is achieved by measuring the transmission properties of the water surface by means of the decrease in the light intensity of a light beam repeatedly reflected between two mirrors and incident at an angle to the water surface and simultaneously determining the transmission property of the gas phase situated above the water surface and composed mainly of water vapour by means of the change in the intensity of a light beam travelling parallel to the water surface. <IMAGE>

Abstract: Such methods and arrangements are used in video surveillance systems which monitor a certain area for changes. It is the object of the invention to specify a video control system providing reliable suppression of false alarms and, at the same time, reliable detection of alarm-relevant changes. This is achieved by the fact that in a currently recorded video image which is divided into a multiplicity of fields and in which a brightness value is integrally determined for each field, the quotient of this brightness value and the brightness value of the corresponding field from a preceding image is formed. When an alarm-relevant change is not present, the quotient is approximately equal in all fields whilst the quotient deviates from the other ones in the case of alarm-relevant changes in the relevant fields. <IMAGE>

Filed: 1992-11-28
Abstract: The invention relates to a method for the trimming of, in particular, hot-rolled metal strips (1) by means of a trimming shear (2). At a predetermined distance ahead of the trimming shear, irregularities in both strip-edge regions are continuously detected. These parameters are used to calculate the width of the edge strip remaining at both edges of the strip and its respective position in relation to the width of the finished strip. In addition, the distance travelled or to be travelled from the detected irregularities to the trimming shear (2) is determined. If the width of the edge strip falls below a minimum value, the cutting heads (3) of the trimming shear (2) are moved by real-time control or regulation at a speed of travel matched to the speed of the strip, to a cutting width which prevents the running out of one or both edge strips. As a result, malfunctions are largely avoided. <IMAGE>
