A high-voltage capacitor is used to transmit energy and has an insulator housing, wherein at least two serially connected capacitors, which are mounted in parallel, are arranged. Said capacitors are made of, respectively, a serial connection of individual capacitors which are embodied as stackable capacitor elements. The resulting high-voltage capacitor is compact and economical. Each capacitor element comprises several individual capacitors which are maintained in an isolated manner, whereby the number corresponds to the number of serially connected capacitors, such that said serially connected capacitors are formed by one stack of capacitor elements.

The system is intended to provide an isolated power supply for an electrical load. It contains a generator for producing a supply signal, and a transmission path having two separate branch elements. The first branch element is designed for transmission of the supply signal (S1) in the forward direction, and the second branch element is designed for transmission of the supply signal in the backward direction, so that this results in a closed circuit for the supply signal. The two branch elements contain means for isolation. The load can be supplied by the supply signal with an electrical power of at most 100 mW.

摘要:
Known large vibrating conveyors are not readily suitable as such for conveying bulk materials or small articles into or out of a liquid bath, because the liquid transmits the vibrations to other structural parts, for example a vessel for the liquid, as a result of the incompressibility of the liquid. In order to remedy this, the vibrating conveyor device according to the invention has a compressible space or chamber underneath the vibrating part which damps the vibrations, when suitably coordinated with the liquid bath. The space is preferably gas-filled and its damping properties can be varied by feeding additional gas through a line which can be shut off by a member, or by bleeding some of the filling through a further line which can likewise be shut off by a member.

High resolution resist structures with steep edges are obtained using standard equipment, with high sensitivity, particularly in the deep UV range. A photoresist layer consisting of a polymer having anhydride groups and blocked imide- or phenolic hydroxyl groups and of a photoactive component which forms a strong acid during irradiation is first deposited on a substrate, followed by irradiation with a patterned image. The irradiated photoresist layer is then treated with a water-based or a water-alcohol-based solution of a polyfunctional amino- or hydroxy-siloxane, and is etched in an oxygen-containing plasma.

The invention provides a radiation-curable liquid resin useful as a secondary coating of lightwave guides. The resin is a reaction product of (meth)acrylic acid or glyceroldi(meth)acrylate or pentaerythritoltri(meth)acrylate with a 2:1 addition compound of a diepoxide and an .alpha.,.omega. -diol with a mean molecular weight between 600 and 3000, or, a reaction product of (meth)acrylic acid or -acid chloride or isocyanatoalkyl-(meth)acrylate with a conversion product of the 2:1 addition compound and a low-molecular monovalent alcohol C.sub.1 to C.sub.10), a low-molecular bivalent alcohol (C.sub.2 to C.sub.4) or water, where the diepoxide is an aromatic diglycidylether and the .alpha.,.omega. -diol is an .alpha.,.omega.-hydroxy-terminated polyoxyalkylene, an .alpha.,.omega. -hydroxy-terminated polyester, an .alpha.,.omega. -hydroxy-terminated polybutadiene or an .alpha.,.omega. -hydroxy-terminated organo-functional polysiloxane.
摘要:
An electrophotographic recording material is applied on a plate-shaped or drum-shaped substrate in a layer structure of superposed layers which comprises a photoconductive layer and at least the uppermost layer is fashioned of amorphous, hydrogen-containing carbon. The amorphous, hydrogen-containing carbon layer is deposited from a radio frequency excited low-pressure plasma with gaseous hydrocarbon as a reaction gas and in which a self-bias DC voltage is superimposed on the radio frequency field. The a-c:H material obtained in this manner is semiconducting and has photoconductive properties so that it can be employed for the photoconductive layer of the electrophotographic recording material.

An apparatus for transporting agitatable material through a liquid treatment bath, comprising a spiral conveyor trough mounted around a central tube in a gas-tight tank which contains a liquid into which a portion of the trough is submerged. The conveyor trough is provided with at least one product mixer mounted radially beneath the trough which is provided with openings which serve to guide the flow of the liquid. The device is especially effective as an electroplater.
