Abstract: Réseau d'antennes en cornet avec des dimensions d'ouverture non uniformes, dans lequel les cornets individuels s'accordent en phases sur une large bande de fréquence. Le cornet présentant la plus petite ouverture est considéré comme le cornet de référence, et sa longueur (Lh) définit la longueur hors tout de l'autre cornet dans le réseau. Les longueurs d'évasement (Lf) des autres cornets du réseau sont inférieures à la longueur du cornet de référence, et les longueurs (Lw) de guide d'ondes s'ajoutent aux autres cornets de telle sorte que les longueurs combinées respectives d'évasement et de guide d'ondes de chacun des autres cornets sont égales à la longueur du cornet de référence. Les longueurs respectives de l'évasement et de la section de guide d'ondes sont choisies de telle manière que l'antenne en cornet résultante s'accorde en phase avec le cornet de référence sur la bande de fréquence. Par conséquent, des antennes en cornet de dimensions d'ouverture variées, et limitées à une longueur maximum peuvent être accordées en phase sur une bande de fréquence par réduction de la longueur évasée de chaque cornet par rapport à celle du cornet le plus petit ou de référence, et par compensation de la différence de longueur résultante avec une section de guide d'ondes.

Abstract: Appareil permettant d'effectuer de multiples reproductions à partir d'un original, toutes ces reproductions du même original étant de qualité pratiquement identique. Une machine électrophotographique charge pratiquement uniformément un organe d'enregistrement électrophotographique à une tension initiale prédéterminée et expose au niveau de l'image l'organe d'enregistrement chargé, à un niveau d'exposition nominal afin de produire une image de charge latente. Le niveau de tension initiale et le niveau d'exposition sont des paramètres de commande de processus de la machine, qui comprennent également une électrode polarisée pour commander le dépôt de toner sur l'image de charge latente. Sont produits et mémorisés des signaux ayant des valeurs caractéristiques (1) du niveau d'au moins un des paramètres et (2) du niveau de tension de polarisation qui sont liés à une qualité de reproduction désirée d'un original. On produit un signal de comparaison en prenant les valeurs des signaux des paramètres détectés associés aux images de charge latente des reproductions successives d'un original et en les comparant aux valeurs de signaux mémorisés relatives aux images de charge latente correspondantes du même original. Le niveau de tension de polarisation lié à l'image de charge latente varie en réaction au signal de comparaison, produisant ainsi une image développée et ayant pratiquement la même qualité d'impression que celle produite par les valeurs de signaux mémorisés.

Abstract: Bei einem Verfahren zur Ermittlung der einer Brennkraftmaschine zuzuführenden Kraftstoffmenge während eines dynamischen Übergangsbetriebs wird die Kraftstoffmenge aus einem korrigierten Ansaugdruckwert pkorr und der Drehzahl n bestimmt. Der korrigierte Ansaugdruckwert pkorr ergibt sich dabei aus einem gemessenen Ansaugdruckwert pm, unter Berücksichtigung des Umgebungsdrucks und der Umgebungstemperatur sowie von Zeitverzügen zwischen dem gemessenen Ansaugdruck pm und dem im Saugrohr tatsächlich vorhandenen Ansaugdruck während des dynamischen Übergangsbetriebs. Das Verfahren gewährleistet damit eine sehr genaue Zumessung der Kraftstoffmenge während des dynamischen Übergangsbetriebs.

Abstract: Appareil et procédé permettant à un dispositif électronique d'exciter des capacités de charge de valeurs élevées, sans produire des niveaux élevés de bruit transitoire. Des moyens (37, 44) sont prévus pour faire passer un premier courant (12) à travers l'inductance parasite (32) du circuit intégré avant l'activation de l'excitateur de sortie (36), pré-égalisant la capacité de charge. Ensuite, lorsque l'excitateur de sortie (36) est activé et lorsque la capacitance de charge (38) décharge à travers l'inductance (32) du circuit intégré, le premier courant (12) en est retiré à mesure que le courant (13) provenant du condensateur de charge (38) le remplace. Comme un niveau initial de courant passait à travers l'inductance,la cadence de changement de courant passant à travers l'inductance pendant l'activation de l'excitateur de sortie est maintenue approximativement constante, réduisant ainsi le niveau de bruit transistoire produit par le dispositif électronique.
