Abstract: An assembly includes a honeycomb body secured by an inner casing tube in a housing, in particular a housing of an exhaust system of an internal combustion engine. The inner casing tube has an overall length which is bounded axially by two edges and is substantially smaller than the axial length of the honeycomb body. The inner casing tube is also disposed in an approximately axially central position around the honeycomb body and is connected, in particular brazed, thereto in at least one axial connection region. The inner casing tube has a region within the axial connection region in which it is connected to the honeycomb body on the inside or attached directly adjacent the latter on the outside and is connected to the housing. Regions of the inner casing tube which are not connected to the housing but are connected to the honeycomb body toward the inside are constructed as radially elastic spring elements.

Abstract: To fabricate a trench capacitor in a substrate, a trench is formed in the substrate. The trench has an upper region and a lower region. In the trench, first of all nanocrystallites and/or a seed layer for nanocrystallites are deposited in the upper region and the lower region. Then, the nanocrystallites and/or the seed layer are removed from the upper region of the trench by means of an etching process. The etching parameters of the etching process are selected in such a way that the seed layer and/or the nanocrystallites which are uncovered in the upper region and the lower region are removed only from the upper region. Consequently, an expensive mask layer can be avoided in the lower region of the trench.

In one embodiment according to the invention, the guide elements are grooves with toothed rack profiles on an end of the grooves. Guide devices such as a pinion, groove block or roller engage in the toothed rack profiles to guide and transport the device.

Abstract: A control for a motor vehicle drive having an automatic transmission includes a circuit configuration for generating an output signal adapting shifting points to a load state of the motor vehicle from an evaluation of a power takeoff rpm of the transmission or of a variable equivalent to it. The circuit configuration ascertains a deviation between a calculated and a measured power takeoff rpm in successive time intervals and forms a correction term by multiplication with a factor. At least one characteristic curve memory stores shifting points of the transmission. The at least one characteristic curve memory receives the correction term as an output signal for adapting a characteristic curve to the load state. In a method for controlling a vehicle drive having an automatic transmission, shifting points or characteristic curves for shifting are varied as a function of driving parameters.
