Patent EP-0459499-A1 (EP)
Inventor: CAWTHON GARRET DEAN
IPC: C07F7/08
Filed: 1991-05-31
Abstract: The present invention is a process for reducing the content of halogen bound to the silicon atom of halosilacycloalkanes. The process employes an alkylaluminum hydride as a reducing agent. Alkylaluminum hydrides have been found to be highly effective in removing the halogen bound to silicon, with lessor affect on the reactive silacycloalkane ring. In another embodiment of the present invention, the halosilacycloalkane is added beneath the surface of an excess of liquid alkylaluminum hydride. The temperature and the pressure of the reaction are maintained such that the resultant silacyloalkane products are immediately vaporized and removed from the reaction vessel. This minimizes further reaction of products and improves the yield of desired product.

Abstract: La longueur d'onde (lambda) d'un rayon lumineux à mesurer est déterminée en fonction de la formule lambda = Ds/N à partir du nombre (N) de franges d'interférences ayant des formes d'ondes répétitives prédéterminées qui apparaissent lorsque la longueur du chemin optique est modifiée par la quantité Ds par déplacement en continu d'une partie mobile (7) d'une partie de spectromètre à interférence (1) d'un appareil de mesure de longueur d'onde à vitesse constante. Un compteur de nombre d'ondes (13) compte le nombre de points spécifiques dans chaque période des franges d'interférence entièrement depuis un point de départ de mesure prédéterminé vers un point de fin de mesure prédéterminé, en vue d'obtenir une donnée (Na) relative au nombre d'ondes. Une partie génératrice d'impulsions de référence (21) génère des impulsions de référence ayant une fréquence supérieure à celle des formes d'ondes répétitives des franges d'interférence. Des parties de détection (22a, 23a) détectent le premier nombre des impulsions de référence présentes dans une période des franges d'interférence, le deuxième nombre des impulsions de référence présentes à l'intérieur de la période depuis le point de départ de mesure jusqu'au premier point spécifique des franges d'interférence succédant au point de départ de mesure, ainsi que le troisième nombre des impulsions de référence présentes à l'intérieur de la période depuis le point spécifique final des franges d'interférence jusqu'au point de fin de mesure. Une partie de calcul (26) corrige la donnée (Na) relative au nombre d'ondes et produit une donnée (NA) relative au nombre d'ondes, dans laquelle sont incluses des valeurs de fractions, grâce à l'utilisation des premier, deuxième et troisième nombres, et mesure avec une précision élevée la longueur d'onde du rayon lumineux à mesurer en fonction de l'équation suivante: lambda = Ds/NA.

Abstract: Des données sont enregistrées en superposition sur un support d'enregistrement optique, composé d'un support optique et magnéto-optique combinés, au moyen de creux et dans une couche magnétique. Un dispositif d'exploration optique approprié permet de lire au moyen d'un faisceau de lumière aussi bien les données enregistrées au moyen de creux que les données enregistrées dans la couche magnétique. Afin de supprimer la diaphonie entre le signal de données (PS) obtenu des creux et le signal de données (MS) obtenu de la couche magnétique, deux faisceaux de lumière perpendiculairement polarisés (VL, HL) sont focalisés sur le support d'enregistrement (AT) avec un écartement mutuel prédéterminable (X) et sont réfléchis sur quatre photodétecteurs (VP, E, F, G) en fonction de leur direction de polarisation. Les signaux de données (PS, MS) et les signaux de réglage (FE, TE) des circuits de réglage de la focalisation et du suivi de piste sont obtenus à partir des signaux de sortie des photodéctecteurs. Ce dispositif d'exploration optique est utile pour des appareils d'enregistrement et de reproduction magnéto-optiques.
