Patent CA-2179098-C (CA)
Inventor: TSUTSUI KEIICHI
IPC: G11B7/095
Filed: 1996-06-13
Granted: 2005-09-20
Abstract: The invention provides a recording and/or reproduction apparatus for a record medium in the form of a disk by which the necessity for adjustment of an inclination of a head with respect to a disk upon production of the apparatus is eliminated and correct reproduction of data can be assured irrespective of a variation with respect to time. A control circuit controls an offset generation circuit to generate a predetermined offset signal. A skew servo circuit drives a skew motor in response to the offset signal to adjust the relative angle of an optical head with respect to an optical disk to a predetermined angle. A level detection circuit detects the amplitude of the tracking error signal then and outputs it to the control circuit. The control circuit adjusts the offset signal to be outputted from the offset generation circuit so that the amplitude of the tracking error signal may be maximum.

Title: Completion of calls to a preferred agent in an automatic call distributor
Inventor: OTTO MARY RITA
IPC: H04M3/51
Filed: 1996-08-27
Granted: 2000-06-27
Abstract: This invention relates to methods and apparatus for completing calls to selected agents of an ACD (Automatic Call Distributor). In accordance with this invention, callers to the ACD are frequently assigned a preferred agent for handling their transactions. When these callers call the basic number of the ACD, they are identified and routed preferably, to the preferred agent if that agent is logged on. If the callers have not completed a transaction, the agent who is serving a call for that transaction provides a transaction number to the caller and the caller subsequently is connected to the agent associated with that transaction number. Advantageously, callers can normally be served by the same agent while still having the advantage of having their calls queued to any available agent of the ACD if the preferred agent for handling a caller or handling a transaction is not available.

Abstract: Verre à focale variable dont la forme périphérique peut être arbitrairement spécifiée, destiné à être utilisé dans des lunettes, qui inclut un verre rigide (12) destiné à fournir à l'utilisateur la correction des distances, et un verre rempli de liquide entouré par une membrane (15) élastomère étirée et dilatable destiné à fournir une correction supplémentaire de près variable. Le liquide (21), d'un volume fixe, est contenu dans le champ de vision entre la membrane élastomère et le verre rigide. La variation de la puissance optique du verre rempli de liquide est obtenue par déplacement d'un support de membrane auquel est attachée la périphérie externe de la membrane élastomère étirée. La forme de la membrane dilatable est maintenue pratiquement sphérique, en dépit du fait que la circonférence de la membrane n'est pas circulaire. On y parvient en plaçant la membrane sur un élément d'écartement transparent qui a sensiblement le même indice de réfraction que le liquide et qui comporte une ouverture circulaire définissant la zone libre de la membrane. Une paire de lunettes est composée de deux verres à focale variable montés sur une monture dotée d'un dispositif d'actionnement destiné au réglage des focales et monté sur la monture entre les verres.

Les circuits comportent un circuit de sélection et de commutation (la figure) conçus pour recevoir les premier et second signaux de synchronisation redondants (HORLOGE A et HORLOGE B), de désigner l'un des signaux de synchronisation redondants comme ACTIF et comme INACTIF, et de faire du signal de synchronisation ACTIF un signal de référence de synchronisation de sortie, donc le circuit de sélection de commutation commutant également la désignation des signaux de synchronisation ACTIF et INACTIF et le signal de référence de synchronisation de sortie en réponse à la détection d'une erreur ou d'une commande de commutation d'horloge. Le signal de synchronisation ACTIF est envoyé à un premier trajet de temporisation (TRAJET DE TEMPORISATION A) présentant une valeur de temporisation programmable, qui retarde et produit un premier signal de synchronisation de sortie. Un deuxième trajet de temporisation (TRAJET DE TEMPORISATION B) reçoit le signal de synchronisation redondant INACTIF et produit un second signal de synchronisation de sortie. Les circuits comportent également un détecteur de phase (50) qui reçoit les signaux de synchronisation de sortie ACTIF et INACTIF et produit un signal d'état indiquant la relation de phase existant entre les deux.

Granted: 2001-12-11
Abstract: Composition de béton à haute performance et à faible dégagement de chaleur, présentant une teneur extrêmement faible en ciment et un rapport eau/matériaux de type ciment élevé. Cette composition présente des résistances élevées, un faible dégagement de chaleur d'hydratation, une excellente stabilité volumique, une faible perméabilité au chlore et un pH faible. Afin de réduire la teneur en ciment sans nuire aux performances élevées du béton, on utilise de la fumée de silice et de la farine de silice en grandes quantités. Cette composition de béton peut être utilisée pour des structures de béton massives et autres applications nécessitant un faible dégagement de chaleur d'hydratation. Elle présente cependant une résistance à la compression comparable au ciment à haute performance standard.

Abstract: The method and apparatus for forming composite wood products particularly composite veneer like products which may be intermediate products and laminated to form the final composite product. Strands are fed from a source of supply at a metered rate, entrained in an air stream and carried along a confined path between an entrainment zone and the source of supply. Strands are condensed onto a surface to form a veneer lay-up of at least one layer of strands on the forming surface and this veneer lay-up is carried from the path and deposited onto a collecting surface and later consolidated into a composite product. Entraining air and strands not forming veneer are separated in the supply station, the strands fall onto the supply of strands and energy is added to the separated entraining air and it is returned to the entraining zone.
