Small-size motors, particularly vehicle step motors in a system used to adjust vehicle parts, are connected directly with a housing in which an assigned electronic control system is housed. A bus supplies each of the motors or its associated electronic control system with adjusting commands and energy. The housings in which the electronic control systems are housed, are closed off tightly with respect to dust and dirt but not with respect to vapor, so that moisture can diffuse out of these housings. This arrangement permits a simple and operationally reliable construction.

Small-size motor and a process for manufacture and use thereof

A circut arrangement for serial data transfer has a transmitting device with several bit-parallel input information units, a serial data transfer line and a receiving device via which the transferred data are correspondingly converted into bit-parallel output information units to drive control elements or logic circuits. The data to be transferred forms on the data transfer line a data word composed of a start pulse, several information units corresponding to the number of bit-parallel input information units forming a data block, and a defined data pause. By cascading several transmitting and receiving devices of the same kind, the number of bit-parallel, input and output information units can be altered, whereby the data word on the data transfer line is also altered by sequential joining of a corresponding number of data blocks, each having the same number of information units.
