Inventor: HSIA JAMES C
IPC: A61F9/008
Filed: 1990-03-19
Abstract: Dans un traitement non invasif du glaucome, une partie de la sclérotique est colorée par voie iontophorétique avec un colorant ayant une absorption à une longueur d'ondes à laquelle la cornée de l'oeil est particulièrement transmettrice. Un rayonnement provenant d'un laser de coloration synthonisable est synthonisé de manière spécifique sur l'absorption du colorant pour l'ablation. Le colorant appliqué par iontophorèse traverse la conjonctive et entre dans la sclérotique pour identifier une région sur laquelle on envoie au travers d'une goniolentille un rayonnement de laser colorant de puissance relativement élevée. Le faisceau de puissance élevée est dirigé en utilisant un faisceau laser de visée de faible puissance couplé dans le même chemin optique que le rayonnement du laser colorant et amené par l'intermédiaire d'un système d'apport à lampe fendue et fibre optique conique. Le laser produit des impulsions entre 75 et 750 millijoules, d'une durée de 1 à 30 microsecondes, de préférence environ 10 microsecondes. Un point de 100 à 300 microns est éclairé.

Abstract: Un générateur miniaturisé de son dynamique comporte une membrane, un aimant permanent possédant des pièces polaires, une culasse d'aimant et une bobine. La culasse est configurée de sorte qu'elle constitue un logement ou un boîtier du générateur de son. L'aimant permanent et les pièces polaires sont disposés dans un creux situé dans le boîtier ou la culasse et sont entourés par la bobine qui est reliée à la membrane à une zone périphérique de celle-ci. La membrane est disposée au-dessus du système à aimant du creux et est fixée à l'extérieur du boîtier. La réponse dynamique du générateur de son est déterminée par les paramètres magnétiques, électriques, mécaniques et acoustiques qui sont utilisés lors de la configuration du générateur de son. En variant certains de ces paramètres, la fréquence et l'amplitude d'une résonance peuvent être choisies de sorte que le générateur de son puisse reconstituer la fonction de transfert auditif naturelle dans le domaine de 2-4 kHz dans le méat humain. Ceci rend le générateur de son particulièrement adapté à l'utilisation dans les appareils de correction auditive.

Abstract: procédé et appareil améliorés de spectrométrie de masse à source de plasma. L'appareil comprend: un générateur (16) de plasma (15) dans un gaz sous une pression essentiellement atmosphérique; un dispositif (4) d'introduction d'un échantillon dans le plasma, l'échantillon étant ionisé afin de former des ions d'échantillon (17); un dispositif (19, 23) de transmission des ions du plasma à une chambre sous vide (24); un filtre de masse (26) agencé dans la chambre sous vide; un détecteur d'ions (58) essentiellement non multiplicateur qui comprend un collecteur d'ions (59) et qui est sensible à la charge d'au moins une partie des ions de l'échantillon qui traversent le filtre de masse; et un dispotitif inhibiteur de la réponse du détecteur à des particules électriquement neutres. Typiquement, le détecteur comprend un suppresseur (63) et un dispositif (64) qui polarise négativement le suppresseur par rapport au collecteur, de même qu'un écran (61) qui protège le suppresseur contre des particules neutres. On obtient ainsi une plus grande plage dynamique et une sensibilité réduite au bruit.

Abstract: This invention relates to a high speed solenoid valve device equipped with a main body (30), a high speed solenoid valve portion (30S) disposed inside the main body and a logic valve portion (30L). In order to reduce the overall dimension of the apparatus, a plate (32) for allowing a solenoid valve sleeve (31) and a control chamber (22) to communicate with a solenoid valve input port (31b) is guided directly by the inner wall of the main body (30), a solenoid valve output port (31a) is formed directly in the solenoid valve sleeve (31) and these solenoid valve sleeve (31), plate (32) and logic valve sleeve (33) are disposed inside the main body in a close contact and stacked state. When the coil of the solenoid valve is not excited, the solenoid valve and the logic valve are closed by the action of a return spring (24) and the communication between a main body input port (11) and an output port (12) is cut off. When the coil is excited, the solenoid valve is opened and consequently, the logic valve is opened and the main body input port (11) and the output port (12) communicate with each other.

Abstract: Procédé et appareil de mesure et de commande d'un procédé industriel consistant à détecter la transmittance moyenne d'un faisceau de rayonnement qui passe au travers du matériau du procédé. Une source de rayonnement (28) ayant une intensité Io est positionnée sur un côté du matériau à mesurer et un détecteur (32) approprié de rayonnement est positionné de l'autre côté du matériau. L'intensité du rayonnement transmis, I, est mesurée par le détecteur. Un indice Z proportionné au degré de non uniformité de la variable dans le matériau est déterminé, et un signal du procédé est généré à partir d'une relation quantitative entre I, Io et l'indice Z. Dans un premier mode de réalisation d'un système de mesure et de contrôle du poids de base du papier dans un procédé de production de papier, l'indice Z indique la non uniformité de la distribution de la masse de matière dans la feuille et cet indice est déterminé par des mesures à l'aide d'une jauge séparée de formation fonctionnant en ligne avec le détecteur de poids de base mais indépendamment du détecteur. Dans un second mode de réalisation mis en oeuvre dans un tel procédé de fabrication de papier, l'indice Z proportionné au degré de non uniformité de la masse de matière est dérivé de la déviation standard du signal d'intensité du rayonnement détecté, ou de la déviation standard équivalente du signal de sortie du poids de base.

Title: Device for tightening a driving belt
Inventor: MONDINI GIANCARLO DR
IPC: F16H7/12
Filed: 1991-11-18
Abstract: In a ring-spinning machine, the driving belt for the spindles is prestressed by means of a tensioning roller (18,19) which is mounted on an angle lever (22). One leg (24) of the angle lever (22) rests on an elastic element or a hose (25) filled with a pressure medium and is thereby prestressed. The loading of the elastic element with the pressure medium can be controlled centrally, for example when the spinning machine is switched on or shut down or for maintenance work. This affords a substantially easier operation and the advantage of the possibility of relieving the driving belt when it does not have to transmit any power. <IMAGE>

Abstract: The invention relates to a plasma CVD method for the deposition of a thin film of amorphous silicon, or an amorphous silicon alloy, on a substrate by glow discharge decomposition of a raw material gas such as silane gas. The degradation of the photoconductivity of the obtained amorphous silicon film by irradiation with light is suppressed by mixing xenon gas with the raw material gas such that at the entrance to the reaction chamber the volume ratio of xenon gas to the raw material gas is not less than 1 and, preferably, not more than 30. A nearly comparable effect can be gained, and the material cost can be reduced, by mixing 1 part by volume of the raw material gas with 0.05 to 1 part of xenon gas and 5 to 30 parts of hydrogen gas.
