Patent EP-0439492-A1 (EP)
Inventor: LOW DOUGLAS W
IPC: H05B6/66
Filed: 1989-10-13
Abstract: Un four à micro-ondes (22) utilisé sur des transports (10) où une alimentation électrique à courant continu (28) est disponible, utilise un premier onduleur (100) pour générer une alimentation à courant alternatif qui alimente les composants du four à micro-ondes autres que le magnétron (33). L'alimentation électrique à courant alternatif interne reçoit un courant relativement faible par l'intermédiaire de dispositifs de verrouillage (46, 48) du four pour commander un onduleur (106) qui envoit un courant de haute tension au magnétron (33). Un relais (112) qui détecte lorsqu'une alimentation à courant alternatif externe est disponible, provoque une commutation automatique qui désaccouple l'alimentation à courant alternatif interne de l'onduleur de puissance (106) pour permettre un fonctionnement classique avec une alimentation de puissance de la ligne externe à courant alternatif (24, 24'). Lorsque l'alimentation électrique externe à courant alternatif (24, 24') n'est plus appliquée, le four à micro-ondes (22) commute automatiquement pour fonctionner à partir de l'alimentation à courant continu disponible (28). Un ventilateur de refroidissement efficace est entraîné par un moteur à courant continu (35, 234). Pendant un mode de fonctionnement avec alimentation à courant continu, la puissance électrique à courant continu disponible au niveau de la prise centrale de l'enroulement primaire (206) du transformateur (208) est utilisée pour entraîner le moteur à courant continu (35, 234).

Abstract: Fuel compositions for internal combustion engines, and more particularly, fuel compositions for use in fuel-injected internal combustion engines are described. The fuel compositions comprise a major amount of a liquid hydrocarbon fuel and a minor, property-improving amount of a hydrocarbon-soluble dispersant prepared generally by the post-treatment of a nitrogen-containing composition with mono- and polycarboxylic acids which may be aliphatic or aromatic carboxylic acids although aromatic polycarboxylic acids are preferred. The nitrogen-containing compositions which are post-treated in accordance with the present invention are obtained by reacting an acylating agent with alkylene polyamines or alkanol amines. When fuel conpositions of the present invention are utilized in internal combustion engines, and in particular, fuel-injected internal combustion engines, the amount of solid deposits of the various parts of the internal combustion engines are reduced. In particular, the use of such fuels prevents or reduces intake system deposits and injector nozzle deposits. Accordingly, methods for reducing or preventing the buiid-up of deposits in internal combustion engines also are described.

Abstract: L'invention se rapporte à un filtre servant à éliminer d'un fluide les substances étrangères par filtrage. Le filtre de la présente invention utilise comme logement un sac composé d'un film plastique ne laissant pas passer le fluide et est produit par un procédé qui consiste à effectuer la fusion par thermoscellage d'un film thermofusible, par exemple en polyéthylène, avec un film généralement utilisé pour les filtres, tel qu'un film en polysulfone, à former un espace fermé en forme de sac sur un ou sur les deux côtés du film du filtre, et à ménager une entrée et une sortie. Ainsi, même un filtre de précision ou un filtre à grande superficie peuvent être produits facilement, complètement et, de plus, économiquement de la même façon que dans les procédés de fabrication de sacs. Le filtre de la présente invention est le plus approprié pour être utilisé comme filtre de précision basse pression, par exemple lors du filtrage final de substances médicales ou lors de transfusions sanguines, et sa pression utile peut être ultérieurement augmentée grâce à l'utilisation d'une boîte de renforcement ou similaire.

Abstract: Coding process. Reed Solomon coders are used to code audio signals which are recorded on a CD in accordance with the CD standard. First parity symbols are produced in a retroactive shift register. To obtain a simple circuit, the first parity symbols are shifted from the retroactive shift register into a storage shift register. After a given number of cycles, the direction of data flow in the storage shift register is reversed. During read-out of the parity symbols, the parity symbols calculated in the retroactive shift register (S1,..., Sn) are combined with those of the storage shift register (R1,..., Rn) in an adding device (A2).

Title: Semiconducteur
Inventor: MICHEL HARTMUT
IPC: F02P7/03
Filed: 1990-08-24
Abstract: Le semiconducteur comporte une première couche (1) dotée de N+, une deuxième couche (2) dotée de p, une troisième couche (3) dotée de n- et une quatrième couche (4) dotée de p. La couche (1) constitue un émetteur côté cathode, la couche (4) un émetteur côté anode avec les métallisation correspondantes (6 et 7). Selon l'invention, le semiconducteur permet de déclencher un processus de basculement grâce au fait que les deux couches du milieu (la deuxième couche (2) et la troisième couche (3)) sont caractérisées par une épaisseur et un dosage tels que la zone de charge spatiale, lors de l'application d'une tension au semiconducteur, s'étende à la transition pn la plus proche (entre la troisième couche (3) et la quatrième couche (4) et/ou la première couche (1) et la deuxième couche (2)) de manière que l'amplification de courant alpha(alphapnp et/ou alphanpn) augmente. Le processus de basculement peut également être déclenché par le fait que la zone de charge spatiale atteint une transition pn très proche. Le composant objet de l'invention est caractérisé par de faibles variations de des paramètres UBO et IH, surtout si on utilise pour la couche du milieu (3) un matériau Si doté de n (rho 100 OMEGAcm). Les paramètres UBo, IBO et IH du composant objet de l'invention peuvent être réglés de manière sensiblement indépendante. En utilisant ces composants on peut réaliser des circuits en série constitués de nombreux éléments, et surtout on peut construire très facilement des empilements de composants pour des tensions très élevées, qui sont surtout utiles comme commutateurs passifs rapides haute tension pour augmenter la vitesse de montée des impulsions de tension élevée du circuit secondaire d'un système d'allumage.
