Abstract: An electrical machine, preferably a blower drive mechanism for a motor vehicle, having a shaft which is supported in at least two bearings with a specified axial play; a cylindrical bearing is secured in a bearing seat of an end shield and rests directly on the bearing seat. The cylindrical bearing has a cylindrical outer circumference, and the bearing seat is a sleeve with a cylindrical inside diameter, into which sleeve the cylindrical bearing is secured with a press fit on the outer circumference and is held axially in the bearing seat by the thus-attained frictional engagement. This has the advantage that more-precise adjustment of the longitudinal play of the armature is possible. Moreover, no additional components such as retaining springs are necessary.

Abstract: A CMOS-compatible DMOS transistor can be designed by virtue of a suitable layout configuration optionally for very high drain voltages or for power amplification at very high frequencies and which can be produced at a low level of additional cost in comparison with a conventional sub-?m production technology for CMOS circuits. A gate insulator of the transistor is of a unitary thickness under a control gate in the entire (active) region through which current flows. A zone of increased doping concentration (well region) which is near the surface and which determines the transistor threshold voltage is so arranged under the control gate that it occupies the entire area under the control gate which is on the active region and ends within a so-called drift space between the control gate and a highly doped drain region. The entire surface of the drift space is covered by a zone of the conductivity type of the drain region (VLDD), which is lowly doped in comparison with the highly doped drain region.
