Abstract: A method is provided for primary control of a steam turbine installation in network operation, which provides at least two pressure stages, these being a high-pressure and a low-pressure steam turbine stage, in which for storing reserve power a live steam valve along an operating-steam feed line to at least one pressure stage of the steam turbine is operated in a throttled manner, the live steam valve, in the case of a reducing network frequency and network frequency boosting which is necessary as a result of this, is transferred to an at least less throttled state. At least some of the partially expanded operating steam which issues from the high-pressure steam turbine stage is introduced directly without reheating, into the low-pressure steam turbine stage for further expansion.

Abstract: Disclosed are compounds of Formula (I), pharmaceutically acceptable salts and solvates thereof, compositions thereof, and methods for their preparation and uses for treating viral infections mediated at least in part by a virus in the Flaviviridae family of viruses.

Abstract: A supply pump actuating turbine, in particular for a power plant, that includes at least two jet sectors for introducing a working gas into the turbine, a line system for connecting the at least two jet sectors to at least two different sources of working gas, and a valve arrangement for setting the supply of the jet sectors with the working gas from at least one of the sources. The valve arrangement and the line system are designed in such a way that at least three operating states can be set: a first operating state, in which all the jet sectors are supplied with the working gas of the first source, a second operating state, in which all the jet sectors are supplied with the working gas of the second source, and a third operating state, in which at least one of the jet sectors is supplied with the working gas of the first source and at least one other of the jet sectors is supplied with the working gas of the second source.

Abstract: A semiconductor memory device for receiving a charge, includes a substrate, a transfer gate overlying the substrate, a storage device coupled to the transfer gate, a deep depleted region formed in the substrate under the storage means, and a bit line for initially receiving the charge and the substrate receiving the charge via the transfer gate. The substrate is highly resistive in a deep depletion mode, if no charge is stored therein, and has a relatively low resistivity in a charged state. Further, a process of forming a semiconductor memory device, includes depositing a first gate oxide over a substrate having a trench and depositing a nitride over the first gate oxide, forming openings in the nitride down to the gate oxide, and depositing polysilicon over the nitride and etching first spacers in the polysilicon along the sidewalls of the openings in the nitride. A second polysilicon material is deposited over the first spacers and substrate and second spacers are formed in the second polysilicon material.

Abstract: A method of fabricating a self-aligned borderless contact in a semiconductor device. The semiconductor device includes a first conductor level, a patterned conductor level defining a pair of spaced apart conducting segments, and a dielectric insulating layer disposed between the first conductor level and the patterned conductor level, and over the pair of spaced apart conducting segments of the patterned conductor level. The method comprises the steps of etching a contact hole in a selected region of the dielectric insulating layer which lies above and is substantially aligned between the pair of the segments. The etching continues through the dielectric insulating layer so that a portion of the dielectric insulating layer remains between the contact hole and the first conductor level. A spacer is formed which lines the contact hole.

Abstract: A semiconductor memory device includes a trench formed in a semiconductor substrate. Conductive material is formed in the trench and is insulatively spaced from the semiconductor substrate to form a capacitor. A transfer gate transistor includes source/drain regions formed on a surface of the semiconductor substrate and a control gate which is insulatively spaced from a channel region between the source and drain regions. A buried strap electrically connects the capacitor to one of the source/drain regions of the transfer gate transistor. A portion of the buried strap includes recrystallized silicon.

Abstract: A windshield washing system, especially for motor vehicles, is provided with a wiper shaft, on which a wiper arm can be non-rotatably fastened and which wiper shaft includes an axial bore in order to receive a line made from form-stable plastic material with at least one channel, through which at least one washing nozzle moving in pendular motion with the wiper arm during the wiping process can be provided with washing liquid. In order to ensure that the wiper shaft takes along the line, the line is form-fittingly connected with the wiper shaft in the swivelling direction of said wiper shaft at the end of the wiper shaft turned away from the wiper arm.

Abstract: A wiper arm with a wiper rod, at the one end of which a wiper blade is fixed.The wiper rod is provided with a coating, onto which coating a hose channel is formed. Furthermore, it is possible to fix additional hose supports onto the wiper rod or onto the joint.

Abstract: The invention relates to a wiper and washing system including a tube with two separate channels, a nozzle head with at least two washing nozzles, one of which is connected to the one channel and the other of which is connected to the other channel of the tube, and a connecting piece from which the tube starts off. In order to avoid wrong assemblies, coding the connections between the tube and the nozzle head as well as between the tube and the connecting piece are provided on the tube on the one hand, and on the nozzle head or on the connecting piece on the other hand.
