Patent CA-2261831-A1 (CA)
Inventor: HAMABE KOJIRO
IPC: H04B7/005
Filed: 1999-02-15
Abstract: En transfert cellulaire souple sur un système de communication radio mobile à accès multiples par division de code, les interférences provoquées lors d'une liaison descendante par une émission à partir d'une pluralité de stations de base pour une station mobile peuvent être limitées. La commande de puissance d'émission se fait en fonction de la commande de la station mobile uniquement dans la station de base faisant office de station de base primaire qui a un affaiblissement de propagation minimal avec la station mobile lors du transfert cellulaire souple, et les stations de base autres que la station de base primaire émettent avec une puissance limitée. En comparaison avec la commande de puissance d'émission opérée par l'émission classique depuis plusieurs stations de base, les interférences pour la station mobile périphérique peuvent être réduites afin d'obtenir des capacités plus élevées de liaison descendante. En outre, en restreignant la puissance d'émission d'une station de base autre que les stations de base ayant un affaiblissement de propagation faible avec la station mobile du groupe de stations de base en transfert cellulaire souple, en atténuant modérément la puissance d'émission au lieu de la limiter brusquement, la dégradation de la qualité de réception peut être évitée lorsque l'erreur est provoquée par le choix de la station de base.

Title: Gene identification method
Inventor: YEHIELY FRUMA
IPC: C12Q1/6809
Filed: 1997-11-12
Abstract: A method for the identification of genes that are essential for the maintenance of specific cell phenotypes is disclosed. The method includes the initial step of identifying a cell type with a phenotype of interest. Gene inactivation is performed on an aliquot of cells of the cell type of interest.  Positive selection is then performed to an aliquot of the cell culture to which gene inactivation has been applied. Cells which continue to maintain the phenotype following gene inactivation have not had the gene of interest inactivated whereas cells in which genes necessary for maintaining the phenotype have been inactivated have been lost. Utilizing subtraction analysis between treated and untreated aliquots the gene in the cells which has been inactivated that affects the phenotype of interest is identified. Genes that are identified by the method are also disclosed as well as antibodies directed against the gene product of the identified genes. Further a customized kit for the practice of the gene identification method is also disclosed.

Title: Thermal barrier coating system utilizing localized bond coat and article having the same
Inventor: BOSE SUDHANGSHU
IPC: C23C4/00
Filed: 1999-06-11
Abstract: A thermal barrier coating system for a superalloy substrate is disclosed. The superalloy is preferably of the type that is capable of forming an adherent alumina layer. A bond coat is applied to a local area of the substrate, so that a portion of the substrate remains exposed. The localized area is defined to be the area(s) at which a TBC typically fails first, e.g., the leading and trailing edges of an airfoil, or other area. An alumina layer is formed on the remaining portion of the substrate, and also on the bond coat. A ceramic layer is then applied on the alumina layer. Even if the ceramic material is removed, the localized bond coat remains, and reduces the rate at which the underlying substrate oxidizes. A coated article is also disclosed, as is a system that utilizes a conventional superalloy and aluminide coating with the localized bond coat.
