Abstract: An image forming apparatus has a photoreceptor drum (15) 
whereon a toner image is to be formed, a transfer drum (11) for 
transferring the toner image to a transfer material (P) by 
making the transfer material contact with the photoreceptor 
drum, the transfer drum having a dielectric layer (28), 
semiconducting layer (27) and conducting layer (26) laminated in this 
order from a surface which comes into contact with the 
transfer material, a power source section (32) for applying any 
voltage to the conducting layer, and a grounded conducting 
roller (12) which is located in an upstream section in a 
transfer material transporting direction with respect to a 
transfer position on a surface of the dielectric layer and 
comes into contact with the dielectric layer surface 
through the transfer material. The volume resistivity of 
the dielectric layer is not lower than 40 percent of the 
volume resistivity of the semiconducting layer. In this 
structure, a current component flowing in the circuit is 
greater than a current component causing the dielectric 
layer to function as a power source, thereby accumulating 
charges on the dielectric layer. As a result, stable 
adhesion of the transfer material to the transfer drum, and 
improved image quality are achieved.

Abstract: A vapor recovery nozzle includes a spout construction comprising an outer aluminum tube and an inner nylon tube. The distal ends of the tubes are joined so that the inner tube defines a central fuel passage and, in combination with the outer tube, defines a generally annular vapor return passage. A distal end portion of the outer tube has a reduced wall thickness and its inner end is expanded to mount a locator ring thereon. The spout assembly is telescoped into an adapter that connects the fuel and vapor passages to corresponding passages in the nozzle body. A spout nut threads into the nozzle body and engages the locator ring to mount the spout on the nozzle. The outer spout tube is formed by lathe operations which include turning a fracture groove adjacent its inner end, and, thereafter bending the tube to angle the distal end portion of the tube downwardly from its inner end. A second embodiment teaches the use of structural, synthetic resins in forming the outer spout tube. In an alternate embodiment the outer spout tube is compositely formed an outer end portion that provides increased strength for the that portion, where a thin wall tube is employed.

Abstract: A DC circuit breaking device is provided for interrupting the transmission of direct currents to an electric power system by making external changes to an arc generated upon contacting or separation of contacts (11, 12) in order to rapidly extend and vibrate arc currents. In a self-excited commuting DC circuit breaking device, coils (41, 42) opposed to a fixed and a movable contact (11 and 12, respectively) are disposed around the outer circumference of the contacts (11, 12), and currents flowing through a commutation circuit (2, 3) or the contacts (11, 12) are allowed to flow through the opposed coils (41, 42) so as to apply magnetic fields to the neighborhood of an arc (19). This constitution provides the DC circuit breaking device with high performance so that it can rapidly extend and vibrate arc currents to thereby interrupt direct currents.

Abstract: A process comprising removing surface layer materials from the wafer by inducing micro-fractures in the surface using a rotating pad and an abrasive slurry until all of the surface layer materials are removed; and chemically etching the surfaces of the wafer until all micro-fractures are removed therefrom. Edge materials are removed by abrasive tape. Wafer thickness reduction during recycling is less than 30 microns per cycle. One of the front and back surfaces of the wafer substrate is polished, any dots or grooves being on the non-polished side.

The preferred pad comprises an organic polymer having a hardness greater than about 45 on the Shore D scale, optimally a polyurethane. The pressure of the pad against the wafer surface preferably does not exceed about 3 psi. Preferably, the chemical etching solution contains potassium hydroxide.

Abstract: The present invention relates generally to an improved process for providing uniform step coverage on a substrate and planarization of metal layers to form continuous, void-free contacts or vias in sub-half micron applications. In one aspect of the invention, a refractory layer (16) is deposited onto a substrate having high aspect ratio contacts or vias (14) formed thereon. A CVD metal layer (22) is then deposited onto the refractory layer (16) at low temperatures to provide a conformal wetting layer for a PVD metal. Next, a PVD metal (23) is deposited onto the previously formed CVD metal layer at a temperature below that of the melting point temperature of the metal. The resulting CVD/PVD metal layer (24) is substantially void-free. The metallization process is preferably carried out in an integrated processing system that includes both a PVD and CVD processing chamber so that once the substrate is introduced into a vacuum environment, the metallization of the vias and contacts occurs without the formation of an oxide layer over the CVD Al layer.

Abstract: Selon la présente invention, un codeur vocal (100) reçoit des signaux vocaux (S) codés et émis par un canal de communications (120). Le codeur de données (101) utilise le silence vocal pour émettre des données sur une bande de fréquence vocale via le canal (120), un classificateur de signal (103) assurant la commutation entre les codeurs (100, 101).

Le codeur de données (110) est pourvu d'une ligne à retard dont les variables d'état sont mémorisées et mises à jour dans un tampon (192). Une entrée (144) permettant la transition en douceur en mode de codage vocal transmet à la ligne à retard du filtre de synthèse les variables d'état en tampon à l'occasion du basculement (103, 102, 193) du mode données au mode vocal. Il y a alors génération des valeurs des coefficients dans le filtre de synthèse (115) et génération d'un signal d'excitation (ET(1...5)). Ce procédé permet de prérégler un tampon dans le prédicteur de gain (113, 114) et de générer ses coefficients et gain de prédicteur. Le signal vocal en entrée (S) qui vient d'être détecté est codé (CW) au moyen des valeurs générées au niveau du codeur vocal (100) qui est adapté après l'opération. Le côté réception comporte des décodeurs correspondants pour les modes vocal et données.
