Abstract: The invention relates to a driving agent vacuum pump used in microsystems technology, comprising an evaporator chamber and a pump chamber that are separated by a jet arrangement. The design of the driving agent vacuum pump is improved by: a planar arrangement of at least one jet, which extends vertically in depth and which is situated between two, in particular, parallel plates, these plates closing the evaporator chamber and the pump chamber; an opening in the pump chamber, preferably above the jet arrangement, for drawing in a medium to be pumped, and; an opening for expelling a preferably compressed gas underneath the jet arrangement.

Abstract: A method for fabricating a solar cell (1) comprising a semiconductor substrate (2) is proposed where electrical contacting is made on the back side of the semiconductor substrate. The back side of the semiconductor substrate has locally doped regions (3). The adjacent regions (4) exhibit different doping from the region (3). The two regions (3, 4) are initially coated with electrically conductive material (5) over the entire area. So that the conductive material (5) does not short-circuit the solar cell, the two regions (3, 4) are covered with a thin electrically insulating layer (7) at least at the region boundaries (6). The electrically conductive layer (5) is separated by applying an etch barrier layer (8) over the entire surface which is then removed free from masking and selectively e.g. by laser ablation, locally above the insulating layer (7). The conductive layer is locally removed in the area of the openings (9) of the etch barrier layer (8) by subsequent action of an etching solution.

Abstract: An auxiliary drive for a trailer comprises a carrier that can be moved in relation to a chassis, said carrier holding a drive motor which can be used to drive a wheel of the trailer. The carrier can be swiveled from a drive position to a rest position and vice versa by means of an actuation lever. The moving mechanism provided for transmitting the movement of the manual actuation element comprises an energy storage or a servo-drive in order to prevent the operator from having to exert high operating forces.

Such a multimaster bus system enables several connections to be simultaneously established in the easiest possible way and between the devices connected thereto.

Abstract: Stators for harmonic motors are disclosed. The stators are easy to assemble and include a laminated armature made of sheet metal plates. The laminated armature is formed of a substantially cylindrical laminated star armature with a plurality of radially outwardly oriented pole heads distributed along the circumference of the laminated star armature, and a substantially cylindrical laminated yoke armature having radially inwardly oriented pole teeth and arranged radially outside of and concentrically with the laminated star armature. Each of the pole heads is arranged radially adjacent to a corresponding one of the pole teeth. Windings are applied to the pole teeth before the tooth head sleeve or the laminated star armature are inserted in and joined with th laminated yoke armature.

Abstract: An arrangement for transporting metallic work pieces includes a heat-insulated transport chamber, means for loading and unloading the work pieces, and transporting gear. To enable the flexible and efficient transport of the work pieces among a number of treatment chambers in an arrangement of this type during a heat treatment process, the transport chamber is designed to be vacuum-tight, such that it can be evacuated of air to create a vacuum that will protect the work pieces from environmental influences. In addition, a system for heat treating metallic work pieces, comprising at least two treatment chambers in which the work pieces can be heat treated, is characterized in that an arrangement of this type can be coupled to the treatment chambervia a transfer canal that can be evacuated.

Abstract: The invention relates to aqueous infusion solutions of 1-cyclopropyl-6-fluoro-1,4-dihydro-4-oxo-7-(1-piperazinyl)-quinoline-3-carboxylic acid (ciprofloxacin) which are stable in storage and which can be obtained by mixing between 0.015 and 0.5 g of active ingredient for 100 ml of aqueous solution with sulphuric acid or sodium hydrogen sulfate in a quantity equal to or less than 0.96 mole per mole of active ingredient, sufficient for dissolving the active ingredient and stabilizing the solution. The invention also relates to methods for producing the infusions and the use thereof. The inventive infusions enable the acid content to be reduced, are more stable in storage with the same acid content than other known solutions, and enable a larger proportion of secondary components to be tolerated in the active ingredient than previous standard infusions of ciprofloxacins.

Abstract: To produce a two-chamber arrangement having a first chamber, which is filled with a first component, and a second chamber, which is filled with a second component, two separate bags are sterilized and filled independently of each other with the first/second component. Only after the bags have been sterilized and filled are they connected to each other in such a way that the component contained in one chamber can be transferred into the other chamber so as to be able to mix the two components together. Once they have been filled, the first and second bags are preferably sealed with an openable peel seam, after which the bag ends are welded together.
