Abstract: For the clutch disc of a motor vehicle friction clutch, it is proposed that one of the side discs (13) of a rotational oscillation damper of the clutch disc be supported via a radially elastic bearing ring (21) on a cylindrical bearing surface (25) of a hub (3) of the clutch disc. The bearing ring (21) has a closed ring part (65) which is radially and axially fixed in a central opening (23) of the side disc (13) and, on its inner circumference, has an essentially conical, preferably radially slotted, radially elastic connecting region (73). The connecting region (73) is provided on its inner circumference, either directly or via an integrally formed sleeve region (75), with a cylindrical opposing bearing surface (77) which rests essentially without pretensioning on the bearing surface (25) of the hub (3). Spacer blocks (79) limit the radial spring movement and are used for the rotationally fixed guidance of the bearing ring (21) on the side disc (33).

Abstract: Un procédé de commande de la rotation d'un arbre principal permet d'entraîner deux arbres principaux d'une machine à la même vitesse de rotation et en phase identique de rotation. La commande de la vitesse est effectuée sur la base de première et deuxième instructions de vitesse calculées respectivement selon une formule qui est une fonction d'une instruction de vitesse synchrone de rotation et d'un paramètre correspondant à la configuration d'un système de commande de l'arbre principal (S3 - S7), en réponse à une instruction synchrone de commande émise par un dispositif de commande numérique. Lorsque la vitesse de rotation des deux arbres principaux atteint la vitesse synchrone de rotation (S8), des première et deuxième écarts de position qui correspondent à la vitesse synchrone de rotation sont calculés respectivement selon un formule qui est une fonction d'un gain de commande de la position, et les instructions de vitesse sont elles aussi converties respectivement en première et deuxième instructions de décalage. Un traitement à boucle de commande de la position est effectué sur la base des deux instructions de décalage et des première et deuxième valeurs de rotation de l'arbre principal, et une commande de la vitesse est effectuée sur la base de la sortie de la boucle de commande de la position (S10 - S13). Les valeurs calculées des phases de rotation qui correspondent aux première et deuxième valeurs de rotation depuis que les signaux concernant une rotation des premier et deuxième arbres principaux ont été générés sont respectivement soustraites des écarts de position des deux arbres principaux (S15, S16), en réponse à l'introduction d'une instruction de commande synchrone des phases, réduisant la vitesse de rotation des deux arbres principaux et faisant finalement coïncider les phases de rotation des deux arbres principaux.

Abstract: L'invention concerne les écrans d'entrée de tubes intensificateurs d'image radiologiques. L'écran d'entrée comporte un scintillateur (12) déposé sur un substrat d'aluminium (10); il convertit des photons X incidents en photons visibles qui viennent ensuite exciter une photocathode (16). Des photons lumineux produits par le scintillateur sont émis vers l'arrière et réfléchis par la couche d'aluminium; mais cette réflexion réduit la résolution. Selon l'invention, pour supprimer cette réflexion, on propose de réaliser un écran d'entrée dans lequel on interpose entre le substrat et le scintillateur une couche mince (20) transparente ou peu absorbante (aux longueurs d'onde émises par le scintillateur) calculée pour provoquer un effet anti-reflet. Comme couche peu absorbante anti-reflets on choisira de préférence de l'oxyde d'indium, ou encore de l'oxyde d'antimoine, d'étain ou de bismuth, ou encore une combinaison de ces oxydes, telle que de l'oxyde d'indium-étain. L'épaisseur est de quelques centaines à quelques milliers d'angstroems.

IPC: F04B49/08
Filed: 1990-08-30
Abstract: Les dispositifs hydrauliques à débit variable réversibles sont utiles pour acheminer de l'énergie d'un moteur à un dispositif entraîné. Les composants hydrauliques de tels dispositifs sont en général assez volumineux et rendent difficile le centrage du plateau oscillant desdits dispositifs. Le dispositif (10) de la présente invention comprend deux servosoupapes (68, 69) disposées de façon adaptable à l'intérieur de la cage (11) afin de pouvoir commander séparément le débit du fluide actif en provenance et en direction de deux servoactuateurs hydrauliques (46, 47). Un servomécanisme de réaction (107) sert à déplacer mécaniquement un tiroir (84) de l'une des servosoupapes dans une position servant à évacuer le fluide de l'un des servoactuateurs tandis que le tiroir de l'autre servosoupape est déplacé dans une position servant à commander le passage du fluide dans l'autre servoactuateur. Le mécanisme de réaction déplace aussi les tiroirs pratiquement dans leur position neutre quand un plateau oscillant (21) commandé par les servoactuateurs atteint une position angulaire souhaitée après que l'autre tiroir a été mis en position de commander le passage du fluide dans l'autre servoactuateur. Le mécanisme de réaction est compact et fonctionne concurremment avec l'adaptabilité des servosoupapes de sorte que le centrage du plateau oscillant est simplifié.
