The converter includes heat sinks which have an optimum design. At least some of the heat sinks are connected thermally in parallel.

Abstract: A method for fabricating a capacitor includes the formation of a self-aligned and essentially amorphous passivation edge web. The passivation edge web is formed in the course of a BST vapor phase deposition after prior etching of the lower metal electrode and of the barrier layer, the TEOS layer situated under the barrier layer being attacked by said etching. By means of targeted material redeposition on the side walls of the lower electrode and of the barrier layer, the passivation edge web is subsequently formed from this material deposition.

An estimated value of the indicated torque of the internal combustion engine is calculated as a function of the estimated value of the amount of fuel. An emergency operating mode of the internal combustion engine is actuated if the estimated value and a setpoint value of the indicated torque fulfill a predefined condition.

Abstract: The radio control unit (RDU) which is near to the switching office and which is connected via a transmission link (UT) to radio base stations (RBS) near the subscriber is divided into a plurality of switching office-side interfaces (LEIM) conceived as a downtime unit and subscriber-side interfaces (RBIM) which have multiple access to one another in various ways via a multiple bus system. The subscriber connection data are distributed over the databases of the interfaces (RBIM, LEIM). There is good insensitivity to failures with a low level of expenditure on hardware and development.

Abstract: Two incipiently fused fiber ends are fused to one another by being pushed one inside the other in a longitudinal direction beyond the end face contact site by a variable amount, which is increased in proportion to the greater extent of the poorer quality of the end face as compared to the desired shape of the end face.

Abstract: The integrated memory has a column decoder for decoding column addresses and for addressing corresponding bit lines. The memory also has a first column address bus, which is used to transfer first column addresses to the column decoder, and a second column address bus, which is used to transfer second column addresses to the column decoder. The column decoder in each case addresses bit lines which correspond to the first and second column addresses supplied to it.

Abstract: An integrated circuit has a first voltage generator, which is connected via a first switching element to a contact-making point for external contact making with the circuit. In addition, it has a first digital control device, via which the contact-making point is connected to a control input of the first switching element. In this case, the first control device switches the first switching element on or turns the latter off by a first digital control signal, the level of which is dependent on the potential of the contact-making point. Furthermore, the contact-making point is connected to the input of a second digital control device, which supplies a digital operating mode signal at its output, the level of which operating mode signal is dependent on the potential of the contact-making point.

Abstract: A cell-quadropole cell structure is disclosed which extends the principle of sharing the bitline-stud between two different cells (arranged in a one-dimensional line, e.g. w-direction) further to the maximal possible degree of a sharing in a two-dimensional area (x- and y-direction) consequently forming a cross of four cells around one bitline-stud with each drain region and buried strap extended to the side and the trench attached forming a hook like structure.

Abstract: An integrated drive train control system for a motor vehicle interprets the position of the accelerator pedal and the brake pedal as a wheel torque desired by the driver. A calculating device receives signals representing the positions of the accelerator pedal and the brake pedal. Central control parameters for the drive sources and for the decelerating units of the drive train are generated on the basis of the position signals. A classification device evaluates the sensor signals from the drive train and classifies operating parameters of the motor vehicle.

Abstract: A method and apparatus for using a neural network to control a paper or paper board production machine. By using spectrum measuring devices, the characteristics of the starting materials for the paper and board production and/or their intermediate or final products are registered and the values fed to a neural network. The network provides statements concerning the paper and board quality, from which signals for the feedback and/or feedforward control of the production process may be derived.

Abstract: A DC voltage supply network is described for electric-motor loads, in particular on a ship. A plurality of electricity generation sets are connected in parallel on an output side, and a controllable rectifier or a DC voltage controller is connected downstream of an output of each electricity generation set and has a control input for connection of a voltage regulator. An output of the controllable rectifier or the DC voltage is coupled to an input of the voltage regulator in order to supply a voltage actual value signal and an additional signal, and is connected to the network in order to supply it. The loads are in each case connected to the network via an inverter which can be controlled via a control input by a regulator. In addition to an actual value and the nominal value, an input of the regulator is supplied with an additional signal which is derived from the inverter input voltage and/or the network voltage.

Abstract: A movable contact arrangement for a low-voltage circuit breaker which has a contact lever bracket equipped with contact levers and may move around a pivot bearing for opening and closing the circuit breaker. A journal, which engages with a bearing opening close to an inner end of a stationary conductor segment, is molded onto a main arm of the contact lever bracket. The journal is positioned more or less in the center and has a length that does not exceed the width of the contact arrangement. The bearing opening is also positioned within the width of the contact arrangement. This reduces the width of the circuit breaker, especially in multipole designs, while simultaneously improving the load carrying capacity and service life of the pivot bearing.

Abstract: In order to couple further telecommunications terminal end points automatically to a hybrid telecommunications system—in particular an RNT-specific telecommunications system to which a telecommunications terminal end point is connected, an interface structure is in each case created in the telecommunications interfaces between a public telecommunications network and a DECT/GAP-specific RNT system of the hybrid telecommunications system, This interface structure is constructed in such a manner that each telecommunications interface autonomously, for example in accordance with a predetermined calculation algorithm, forms further connection information that is relevant for the telecommunications connection to the other telecommunications appliances, irrespective of the respectively other interface, This is based on first connection information which is stored in the interface and is relevant for the telecommunications connection to one of the telecommunications terminal end points.

Abstract: The invention relates to an apparatus for turning flat shipments, which are delivered in succession standing on their short sides by a conveyor system, into a recumbent position, without interrupting the conveying. According to the invention, the apparatus has a driven under-floor belt (1) with a low coefficient of friction, which on one side has a projection (5) with a higher coefficient of friction. Located next to the under-floor belt (1) on the side without a projection is a side belt (2), which is positioned obliquely outward and is driven at the same speed as the under-floor belt (1) and likewise has a low coefficient of friction. Downstream thereof in the conveying direction is a conveyor belt (3), whose bearing face together with the bearing face of the under-floor belt (1) defines a plane; the under-floor belt (1) and the conveyor belt (3) are disposed and/or embodied such that the air cushion that forms when the shipments drop is quickly dissipated.

Abstract: The navigation device and the corresponding method for position determination utilize dead reckoning. A position is calculated by a processor on the basis of measured values from a distance sensor and a direction sensor. The measured values are compared with a probable position on a stored digital road map. The deviation between the calculated position and the corresponding position on the digitized road map can be saved. Saved deviations form the basis of a correction value with which the calculated position can be corrected.
