摘要:
A fractionated-rectification high-voltage transformer including a voltage-boosting secondary winding (4) of which at least two output diodes (7', 9') connected to two different stages (4a, 4c) of the secondary winding are positioned on the same level and spaced from the potentiometric unit (6) forming part of the insulating housing (1). The transformer may be used in a television set cathode-ray tube power supply.

L'invention se rapporte à la fabrication des boucles de démagnétisation destinées à être montées sur la verrerie des tubes à rayons cathodiques pour l'affichage d'images en couleurs L'invention a pour objet un procédé de fabrication dans lequel la liaison entre les extrémités (1,2) du bobinage (12) de la boucle de démagnétisation et les conducteurs (4,5) de raccordement au circuit électrique d'alimentation est enveloppée en injectant dans un moule une matière thermoplaste isolante. L'invention s'applique notamment aux boucles de démagnétisation pour récepteurs de télévision en couleurs.
摘要:
A device for mechanically mounting a flexible cable (20) in a cylindrical sleeve (21), including an axially split connector (23) with at least two helical external threads (30) and internal projections (31). The cylindrical sleeve (21) has a screw thread (27) engageable with the external threads on the connector. The cable is mounted by axially snapping the connector into the sleeve then axially inserting the cable. The cable may be disconnected by unscrewing the connector. The internal projections (31) and the engagement between the threads and the screw thread are operable to prevent axial pulling-out of the cable. The device is useful for mounting high-voltage cables in a high-voltage transformer.

Blindage électromagnétique pour transformateur (1) d'alimentation à découpage, en particulier pour téléviseur ou pour moniteur. Il est constitué d'un chapeau réalisé sous forme de cuvette (7) à fond plat (8), et à bords (10) évasés (α) et de relativement faible largeur (L). Il se pose en automatique sur la face supérieure (9) du noyau de ferrite (2), dont il épouse la forme, avec dépose préalable de deux points de colle (11, 12). Cette colle est la même que celle utilisée pour la jonction (13) du noyau de ferrite (2).
摘要:
The present invention concerns a femtocell, and a method at a cellular device for selecting and reselecting a cell, the cellular device being camped on a first cell corresponding to a cellular technology, the cell enabling said cellular device to access at least one service, the method comprising the step of scanning if another cell corresponding to a same cellular technology is available in the area of the cellular device and if a second cell is available and enables the cellular device to access more services than in first cell, reselecting to the second cell.
