Abstract: Un composant de commutation se présente sous la forme d'un circuit intégré. Le composant de commutation possède plusieurs ports d'entrée et de sortie de données avec des ports d'entrée et de sortie d'horloge, un régénérateur d'horloge et une bascule électronique pour chaque port de sortie de données, une matrice de commutation pour coupler chaque port d'entrée de données et son port associé d'entrée d'horloge à tout port de sortie de données et son port associé de sortie d'horloge. Le régénérateur d'horloge obtient le signal d'horloge sortant du noyau de commutation et régénère la forme d'onde du signal d'horloge. La bascule provoque la synchronisation des données sortant du noyau de commutation du composant de commutation avec le signal d'horloge régénéré associé selon le signal d'horloge régénéré. Une pluralité de composants de commutation identiques peuvent être agencés dans un agencement Clos replié ayant plusieurs étages pour obtenir un réseau de commutation d'une taille quelconque désirée. L'utilisation de multiples étages est possible car les moyens de régénération d'horloge associs à chaque port empêchent la dispersion du signal et le biaisement. En faisant passer et en commutant des signaux d'horloge en même temps que les données, la matrice de commutation peut manipuler simultanément des lignes ayant des vitesses différentes, à condition qu'une ligne de vitesse donnée entrant dans le réseau de commutation soit connectée à une autre ligne de même vitesse sortant du réseau de commutation.

IPC: A61C3/02
Filed: 1989-11-16
Abstract: The present invention provides a dental tool which operates as a reamer, while reducing the danger of removing excessive tooth material when boring out the tooth canal. The dental tool includes a first holder end portion designed to be receiveable in a dental tool holder, such that the dental tool holder can rotate the dental tool; a second reaming end portion having a polygonal cross-section and cutting edges tapering longitudinally endwardly to a minimum effective cutting diameter plane, or a point, from a plane of maximum effective cutting diameter, and optimally also having reverse cutting surfaces tapering longitudinally in the opposite direction to an inner plane of reduced effective cutting diameter; and a shank portion extending between the two end portions. The plurality of reamer cutting edges extend axially, and are designed for reaming out a bore into a tooth canal of a patient upon rotation of the tool. The shank portion has an effective cross-section diameter along its length which is smaller than the diameter at the plane of maximum effective cutting diameter or at the plane of reduced effective cutting diameter of the reaming end portion. Most preferably, the shank tapers inwardly towards the first holder end portion, such that the plane of smallest diameter of the shank is located adjacent the first holder end portion.

Abstract: A method of assembling a transformer core in which a lamination of rectangular plates formed of a magnetic material is inserted in the spaces in primary and secondary transformer coils, and in which the opposite ends of the lamination are brought into abutment each other to form the lamination into an annular shape. The lamination of the magnetic material plates is bent into a U-like shape with the transformer coils thereon and is magnetized by energizing the transformer coils, while the opposite ends of each magnetic material plate are restrained from being brought closer to each other. The opposite ends of the laminated magnetic material plates are successively released from the restrained state from the innermost opposed ends of the U-like shape to attract and closely contact each other by the magnetic force. The method is carried out with an apparatus having a flat plate on which the lamination of magnetic material plates is placed, a pair of guide plates having parallel vertical surfaces and used to support the magnetic material plates so that the plates are maintained in the state of being bent in the U-like shape, a pair of pressing members for restraining the opposite end portions of each magnetic material plate from being brought closer to each other, a driver for moving the pair of pressing members step by step toward the open end of the U-like shape; and a device for magnetizing the end portions of the U-shaped magnetic material plates by energizing the transformer coils.

Abstract: A device for mixing and applying two-component materials, has two pistons 15, 16 which can be displaced in cartridges 12, 13 and which can be driven forwards together by an electric motor via a magnetic coupling 30, but which can be drawn back manually and inserted again via a manual wheel 33 when the motor is switched off and the magnetic coupling 30 moved out. At the end of the manual return movement, the pistons 15, 16 drive a shaft 18 which drives a mixing head 14 in rotation and which, simultaneously with the emergence of the pistons 15, 16 from the cartridges 12, 13, disengages with the mixing head 14. In this way, it is possible to remove the cartridges 12 and 13, together with the mixing head 14 connected thereto, out of the device as a unit and to replace them by another unit in order to change the spent cartridges or when the cartridges are still partially full to use the device in the interim to produce a different product. Despite the motor drive which is designed for a slow advance of the pistons 15, 16, such changing of the cartridges is quick and easy due to the manual extension and retraction of the pistons.

Abstract: In an infrared detector device for viewing an object or scene at more than one wavelength, the detector elements (10 and 20) are optimised to have appropriately different infrared responses by being formed in accordance with the invention in different levels (1 and 2) of different material on a substrate (3). Infrared concentrators (55) such as immersion lenses, light-pipes and/or reflectors collect incident radiation (50) over an area larger than the active portion of the associated detector element (10 and/or 20) and concentrate the radiation (50) onto the active portions. The arrangement adopted in accordance with the invention provides adequate space for at least one connection (15) of each upper-level detector element (10) to extend to the substrate (3) through an area of the lower level (2) which is located between the lower-level active portions on which the radiation (50) is concentrated by the associated concentrators (55). This upper-level connection (15) may extend via an island (28) separated from the active portions (22,23) of the lower level (2) by a gap (40), or it may extend on a side-wall of the lower-level detector element (20) when this side-wall is insulated or separated by a p-n junction from the active portions of the detector element (20). The different-response elements (10 and 20) may be arranged one above the other or one between the others when viewed in plan view.
