    摘要: A servocylinder (1, 3, 4) with an electric piston end position transmitter is suggested. It is constructed as a piezoelectric converter (17 and 18). By means of applying voltage to the piezoelectric converter (17 and 18) the latter becomes a regulating element which overcomes a force holding the piston (2) in its stroke end position and removes the piston (2) from its position in which the feed line (7 and 8) of the pressure medium is sealed.

    摘要: To determine if a pulsed beam system, typically an ultrasonic pulsed beam system, which is located externally of a motor vehicle is in operative condition, a transmitter (14) projects a beam to a fixed reflector (16) located on the vehicle, and one (19) of a group of timing stages (18; 19, 20, 21) evaluates the transit time to the reflector. If the transit time to the reflector is slightly less than a predetermined time interval (Tc), so that the threshold timing level (Tc) is passed, a first indication, for example a frequency at a first tone (f1), generated by an acoustic tone generator (30) is reproduced in a loudspeaker; if, then, an obstruction is sensed by the beam, and the distance between the transmitter (14) and the obstruction (17) which forms a reflecting object drops below a first predetermined distance represented by a time period (T2), a second one of the transit time stages responds, and, through logic gates (22-24, 28, 29) provides a second discrete output frequency (f2) in the loudspeaker. If the vehicle closely approaches the reflecting object or obstruction (17), a third frequency (f3) is reproduced by the loudspeaker (26) and, additionally, a warning signal can be given. The system can be connected to the reverse gear or rear light switch, so that, if no obstruction is sensed, and only the signal from the reflector is reproduced, an audible indication of "reverse gear engaged" is provided, thus simultaneously providing a reverse gear signal as well as a signal representative of proper operation of the system. To compensate for ambient condition, dirt on the transmitters, and the like, the timing intervals by the transit time stages responding to the obstruction can be changed (FIG. 2) by providing a calibrating input based on actual transit time from the transmitter (14) to the fixed reflector (16).

    摘要: In a control device the printed circuit board (10) rests on a rim (28) of the housing bottom (26). The power components (14) to be cooled are arranged in the area where the printed circuit board (10) rests on the rim (28). In order to achieve an even contact pressure of the printed circuit board (10) over the entire support surface, a contact pressure on the power component (14) or on the printed circuit board (10) is generated with the help of additional aids. It is possible here to use spring elements (30) or elastomer strips (31) acting on the power component (14). Furthermore, multi-part support elements (40), or respectively plastic elements (45) can also be employed, which respectively act directly on the printed circuit board (10). A good heat dissipation from the power component (14) via the rim (28) of the housing bottom is possible by means of this.
