Abstract: Procédé de production de tissus non tissés consistant à collecter les fibres véhiculées par un fluide à haute vitesse sous la forme d'une bande, et à les introduire dans un dispositif d'emballage de tissus pour qu'elles se superposent. Dans ce procédé, la bande présente de préférence une distribution en section transversale telle que le poids par unité de surface dans les deux bords va en diminuant graduellement en direction du bord. Ce procédé permet de produire une bande filamenteuse ou un tissu non tissé filamenteux de grande largeur et présentant une quantité remarquablement faible d'irrégularités, à l'aide d'une installation de production de tissus non tissés dans laquelle des machines à filer mono- ou bibroches sont reliées directement entre elles. Il est ainsi possible de produire de manière économique un tissu non tissé large en petites quantités par le procédé de filage en connexion. En outre, la largeur ou le poids par unité de surface du produit peut être modifié sans modifier les conditions de filage, de sorte que ce procédé est également indiqué pour produire une variété de produits avec moins de perte lors du changement du type de production.

Abstract: Dans un mode de réalisation, les systèmes de transmission indépendants (101 et 102) comportent des récepteurs additionnels (112 et 113) qui leur permettent de contrôler mutuellement leurs canaux de signalisation de commande à destination de l'extérieur. La signalisation de commande secondaire (204) peut être imbriquée avec la signalisation de commande primaire (201) sur cette ressource de transmission, lesquelles informations de signalisation de commande secondaire sont destinées à être reçues et utilisées par le système de contrôle. Dans un autre mode de réalisation, des systèmes de transmission (301 et 302) possédant des ressources de transmission spécialisées sont pourvus de récepteurs (311 et 316) qui contrôlent les ressources de transmission des autres systèmes de transmission. Les communications entre des unités de transmission (321 et 323) dans divers systèmes sont permutées par l'interaction appropriée des répéteurs et des récepteurs spécialisés ainsi prévus. Dans un autre mode de réalisation, les systèmes de transmission (401 et 402) possédant des ressources de transmission spécialisées sont dotées de récepteurs (416) qui contrôlent les ressources de transmission d'autres systèmes de transmission, et des ''vagabonds'' (423) sont repérés (431) dans des systèmes extérieurs.

Title: Quartz integrated trough/sump recirculating filtered high-purity chemical bath
IPC: H01L21/304
Filed: 1990-06-21
Abstract: A recirculating chemical bath arrangement includes a quartz process tank, and a sump chamber disposed directly adjacent to the process tank. A trough extends about the top portion of the outer walls of the process tank, the trough being inclined to cause gravital flow toward the sump chamber. The sump chamber includes a fitting in the bottom thereof which directs liquid from the sump into a pump/filter circuit, the output of which is fed into the bottom of the process tank. The liquid is thus caused to overflow the process tank and spill into the trough, and flow into the adjacent sump chamber. A plurality of heater units are secured to the exterior surface of the process tank to heat the liquid therein to the proper process temperature. The sump chamber is unheated, so that the liquid entering the pump/filter is at the coolest temperature of the liquid flow cycle. The process tank and sump chamber may be formed integrally of molded and welded quartz plates, and disposed within an outer case that contains thermal insulation.

Abstract: Procédé de commande de servomoteurs, selon lequel les différences entre les caractéristiques dynamiques des machines sont absorbées par un contrôleur et les caractéristiques dynamiques sont corrigées de manière qu'elles soient sensiblement égales. Selon le procédé, on effectue un traitement de lissage de priorités. Si, par convention, les données de lissage de la période actuelle sont représentées par SMD0, et les données de la période précédente sont représentées par SMD1, alors la quantité d'action directe de position FFp est calculée selon l'équation suivante: FFp = α{(1-k)SMD0 + kSMD1}, dans laquelle α représente un coefficient d'action directe de position. En précisant la valeur d'un paramètre k compris dans l'équation, on peut régler les caractéristiques de réponse des machines, le contrôleur compris. Ainsi, même lorsqu'on effectue simultanément des interpolations d'au moins deux axes, on peut sensiblement égaliser leurs caractéristiques dynamiques.
