Abstract: A food processor having a drive subassembly is disposed in the housing and coupled to a first and a second output shaft, each output shaft having with at least one coupling location for an attachment and, in addition, by the interposition of a gear mechanism, the output shafts being driven at different rotational speeds. The coupling of attachments requiring relatively small torques is simplified in that, spaced apart at a different level from its one coupling location, at least one of the two output shafts is provided with an additional coupling location for further attachments.

The configuration has a circuit inserted into the signal path between the test unit and the memory. The circuit contains a data writing device for receiving test data from the test unit and for outputting the test data to the memory, a control signal writing device for receiving test control signals of a control channel of the test unit and for outputting the test control signals to the memory, and a reading/coding device for receiving response data signals and response control signals from the memory. The reading/coding device codes the received response data signals with the response control signals and outputs the coded response signals to the test unit.

Abstract: A trench capacitor is formed in a trench, which is disposed in a substrate. The trench is filled with a conductive trench filling which functions as an inner capacitor electrode. An epitaxial layer is grown on the sidewall of the trench on the substrate. A buried strap is disposed between the conductive trench filling with the second intermediate layer and the epitaxially grown layer. A dopant outdiffusion formed from the buried strap is disposed in the epitaxially grown layer. Through the epitaxially grown layer, the dopant outdiffusion is further removed from a selection transistor disposed beside the trench, as a result of which it is possible to avoid short-channel effects in the selection transistor.

Abstract: A power semiconductor module is presented in which terminal elements are press-fitted into openings in a plastic housing. This measure improves the reliability of the internal bonds between the substrate and the terminal element since there is no longer a risk of the terminal elements loosening in the plastic housing.

Abstract: In order to form an oxide cover on a conductive filling in a trench in a semiconductor substrate an HDP oxide is deposited on the conductive filling using a PECVD method. In this case, the layer thickness on the horizontal surface of the conductive material is greater than the layer thickness on the sidewalls of the trench. Furthermore, the layer thickness is limited in such a way that the surface of the HDP oxide within the trench has a depth with respect to the surface of the semiconductor substrate surrounding the trench, or a layer disposed thereon. In a subsequent CMP step, the HDP oxide is removed from the surrounding surface. In an isotropic etching step, the HDP oxide is removed from the sidewalls. The result is a horizontal insulation layer with a layer thickness that varies only to a slight extent over the semiconductor substrate.

Abstract: There are disclosed polybenzoxazole precursors which can be processed by centrifugal techniques, which can be cyclized to polybenzoxazoles on substrates without difficulty, and which after cyclization to polybenzoxazoles exhibit a high temperature stability. In particular, these precursors and the polybenzoxazoles prepared from them possess high resistance against the diffusion of metals.

Forces may occur in the peripheral direction of the ram head during the compression of bulky objects. The ram head is rotatable relative to the frame in order to reduce the forces introduced into the frame.

Abstract: An electronic component with external flat conductors and a method producing the component includes placing the external flat conductors as waveguides with a defined characteristic impedance on an underside of a dielectric body. The external flat conductors on the underside are surrounded in a coplanar manner by an electrically conductive layer, and a closed, electrically conductive covering layer is disposed on an opposite upper side of the dielectric body.

Abstract: An explanation is given of a method for operating a telecommunications network in which a network element at a network node of a telecommunications network is controlled by a switching computer. Event messages containing details about events occurring during the operation of the computer are generated in the computer. In the course of relaying the event messages, a sequence of destinations is used in which each destination occurs only once. Conditions for the destinations are tested using the details in the event messages in the order prescribed by the sequence.

At least one of the optical waveguides is functionally coupled to at least two electro-absorption modulators, and at least one electro-absorption modulator is assigned at least one optical amplifier. The assembly forms an active electro-optical device that can be driven efficiently.

Abstract: As a consequence of DRAM memory cell miniaturization, the available space for read/write amplifiers decreases in width from hitherto 4 bit line grids to 2 bit lines grids. Conventionally previously known read/write amplifiers cannot be accommodated on this reduced, still available space. Therefore, it has not been possible hitherto to provide read/write amplifiers arranged beside one another which would manage with the novel DRAM memory cell spacings. The principle underlying the invention is based on replacing at least some of the transistors of conventional design which are usually used for read/write circuits by “vertical transistors” in which the differently doped regions are arranged one above the other or practically one above the other. Compared with the use of conventional transistors, the use of vertical transistors saves enough space to ensure an arrangement of a read/write circuit in the grid even with a reduced grid width.

Abstract: A muffler and an associated assembly for cleaning exhaust gas, especially from small engines, include a metal catalyst carrier body and a retaining element which is preferably built into a muffler casing. The catalyst carrier body has a plurality of inner flow paths and is mounted in an exhaust pipe. The retaining element has an opening which surrounds at least a part of a jacket surface of the catalyst carrier body and is directly secured thereto, so that the catalyst carrier body remains dimensionally stable and can be transported. The retaining element can be joined to the exhaust pipe casing which forms an inflow chamber and an outflow chamber in such a way that the retaining element seals and separates the two chambers from each other. Due to the use of the retaining element, no jacket tube is required for the catalyst carrier body which enables the carrier body to be built into a muffler casing both directly and easily. A method for producing the assembly is also provided.

Abstract: A semiconductor component has a cavity formed in a monocrystalline silicon substrate. The wall of the cavity is covered by a cover layer, at least in an upper collar region, and a covering layer is then applied to the surface of the silicon substrate using a selective epitaxial growth method. The cavity is thereby covered in the process. The method is physically simple and can be carried out cost-effectively. In particular, the described method can be used in order to cover a trench prior to high-temperature processes during the production of a DRAM memory, and to open the trench once again after the high-temperature processes, in order to provide a trench capacitor.

Abstract: To demodulate a frequency-modulated signal having an offset, two time constants are provided in a filter unit. The filter unit has two analog or digital low-pass filters or high-pass filters. A first switch is used to change over between the two time constants. If a plurality of bits having the same state succeed one another in a setting mode, the first switch is used to change over to a slower time constant so as not to corrupt the threshold voltage that is to be ascertained. In a normal mode, the stored threshold voltage is, then, used to distinguish between the states coded in an input signal. In such a context, the slower time constant is valid in the normal mode.

Abstract: A method and a multibeam scanning device for ablation of a surface on a rotating drum by laser engraving with a multi-spot array includes simultaneously emitting laser beams from fiber exits disposed beside one another, dividing up each of the beams, after emerging from the exit in an AOM array having a number of AOMs corresponding to the number of exits, into two or more partial beams modulated independently of one another, imaging the exits with an optical system on the surface, and moving the exits, the AOM array, and the optical system together in a drum axial direction while the surface is scanned by the multi-spot array in a drum circumferential direction to make possible, without increasing the number of fiber lasers, an increase in the number of scanning points of the multi-spot array and a reduction of the space required by the scanning device.
