Inventor: HATSUKAWA SATOSHI
IPC: H01L21/337
Filed: 2002-12-02
Abstract: L'invention concerne un transistor à effet de champ à jonction latérale comprenant une première couche d'électrode grille (18A). Cette première couche d'électrode renferme une concentration d'impuretés de type p supérieure à la concentration d'impuretés d'une deuxième couche semi-conductrice (12) et est disposée entre des couches de régions de source/drain (6, 8) d'une troisième couche semi-conductrice (13), qui s'étendent dans la deuxième couche semi-conductrice (12) et la troisième couche semi-conductrice. La face inférieure de la première couche d'électrode s'étend dans la deuxième couche semi-conductrice (12). Le transistor comprend également une seconde couche d'électrode grille (18B). Cette seconde couche d'électrode grille renferme une concentration d'impuretés de type p quasiment égale à la concentration d'impuretés de la première couche d'électrode grille (18A) et possède le même potentiel et est disposée entre les couches de régions de source/drain (6, 8) d'une cinquième couche semi-conductrice (15). La face inférieure de la seconde couche d'électrode grille s'étend dans une quatrième couche semi-conductrice (14). Cet ensemble forme un transistor à effet de champ à jonction latérale possédant une structure permettant de réduire la résistance à l'état passant tout en maintenant des caractéristiques de tension disruptive favorables.
Patent CA-2468571-A1 (CA)
Inventor: WOODHAM VAN
IPC: B27B31/00
Filed: 2004-05-27
Abstract: A log singulator and associated method for conveying and controllably discharging logs are provided. The singulator has a plurality of rotatable lifters with outwardly-extending arm members that contact the logs with a leading side to convey the logs to successive positions, for example, along a log cradle structure. The logs are conveyed to a discharge surface, which can be disposed at a declined angle so that the logs thereon tend to roll toward a discharge position.  Discharge lifters, which are configured to discharge the logs from the discharge surface, have arm members that define angled cam surfaces on their trailing sides. The cam surfaces contact and retain the logs on the discharge surface until the logs reach the predetermined discharge position. Thus, the logs can be controllably discharged, for example, at a desired time.

Abstract: La présente invention se rapporte à un embout d'aspirateur équipé d'un peigne et d'un filtre qu'on utilise dans un procédé de lutte contre les poux et la vermine ainsi que pour ôter les pellicules, cet embout assurant sur le cuir chevelu, un peignage intensif et des retours à des intervalles courts dans la zone d'habitat des poux et de la vermine, lorsqu'on applique un embout équipé d'un peigne amovible qui est situé dans la partie supérieure de l'ouverture de l'embout et qui couvre une partie relativement petite de l'ouverture. L'embout est doté d'un raccord flexible dans lequel même des cheveux longs peut être retenus suffisamment serrés, souples et écartés dans le flux d'aspiration à l'intérieur de l'embout et éventuellement dans le tube raccord de l'aspirateur. Sous le bord des pointes des dents du peigne, l'ouverture s'incline vers l'arrière et vers le bas, de sorte que le peigne peut basculer dans les cheveux pour ainsi concentrer toute l'action de l'aspiration dans les espaces interdentaires pendant le peignage. Sur les deux côtés de la partie de l'ouverture, inclinée vers l'arrière, se trouve un support de peignage qui est simultanément un axe d'inclinaison. Un filtre facilement détachable est fixé à l'intérieur de la connexion entre l'embout et le tube raccord.
