Abstract: 2.1. Existing valve control devices are set up in housings that feature also the complete yoke in addition to the valve spools. 2.2. In order to reduce the assembly effort required as well as the play of the valve domes on the inside of the spool, yoke arrangements are mounted externally on the housing. 2.3. Such valve control devices are suitable for antilock braking systems, anti-slip control systems, electronic brake servos, and electronic stabilizing programs in motor vehicles.

Abstract: Assemblies for electronic components, in particular for automotive electronics, must satisfy increasingly stringent demands in terms of quality and especially cost efficiency. These demands are met by the assembly in accordance with the present invention, wherein the electronic components are arranged on a printed circuit board which in turn is firmly and directly connected to the surface of the metal plate. The printed circuit board and the components are molded using a suitable plastic material in such a way that the molding creates a positive connection with the metal plate at the periphery of the printed circuit board, and thus forms a moisture-proof housing both for the printed circuit board and for the components. Further advantages are in the considerable savings in material and also in a reduced production depth in comparison with known assemblies, resulting in the required cost efficiency.

Abstract: 2.1. Existing valve control devices are set up in housings that feature a cover and a frame in which the valve spools are embedded. Between the cover and the frame, there is the circuit carrier with the electronic components. With the new valve control device, there is no longer to be any need for a housing, and the manufacturing process is to be simplified.

Abstract: Existing valve control devices are set up in housings that feature also the complete yoke in addition to the valve spools.

Abstract: This disclosure describes a procedure for soldering an insulated wire where the wire end features a U- or V-shaped hook with one bending point and is introduced such into the soldering hole of a printed circuit board that the bending point protrudes from the other side of the soldering hole.

Abstract: The invention relates to a switch controller system which furnishes a constant output, voltage over a broad input voltage range. The input voltage may here be lower as well as higher than the output voltage. The large control range is realized by a combination of a down converter and an up converter in a power output stage and a common storage choke. The storage choke is advantageously configured as a flat coil in multi-layer technology and includes a coil core. A novel switch controller system is disclosed which links two known converter concepts having different characteristics with one another.

Abstract: A valve control device of the kind used in ABS or ASR systems as applied in motor vehicles. Such a valve control device comprises a valve block that accommodates the solenoid valves and where a solenoid is assigned to each solenoid valve. The side of a solenoid holder facing the valve block has compartments for accommodating the solenoids, there being an elastic spring element on its compartment base that presses the solenoid against the valve block. Furthermore, each solenoid has first media that, when the solenoid is introduced into this compartment, act together with second media, assigned to the compartment, as a snap latch in such a way as to prevent the solenoid from being pulled out from this compartment. The first and second media are sufficiently elastic that the solenoid can still be moved slightly in all directions in the plane perpendicular to its coil axis.

Abstract: A housing for installation in motor vehicles to accommodate SMD electronic components disposed on one side of a multi-layer circuit board or film. A metal plate serves as the carrier for the circuit board or film, with the planar expanse of the metal plate being the same as or greater than that of the board or film, with the board or film being disposed on, attached to and electrically insulated from the metal plate. When the area of the metal plate is greater than that of the board or film, power components are disposed on the surface of the metal plate in a region not covered by the board or film, whereas when the area of the metal plate is substantially the same as that of the board or film, power components are disposed on the board or film, with the metal plate serving as a heat sink for the power components.

Abstract: To make housings used in automotive engineering for holding electronic components suitable for engine compartment installation, complex measures are taken that involve high manufacturing costs. In accordance with the invention, a housing is provided that permits simple production at low cost and affords dependable protection of the electronic systems, in that the electronic components mounted on an electronic carrier are provided with a protective lacquer, and then covered with a flexible and watertight foil as a protection against moisture in such a way that it provides an airtight and watertight seal on an all-round edge formed by a metal plate supporting the electronic carrier. A housing cover forming the housing in conjunction with the metal plate serves as a mechanical protection.

Abstract: The invention relates to a housing for installation in motor vehicles to hold electronic components arranged on a PCB. In accordance with the invention, the housing comprises a trough-shaped housing section and a metal lid. In addition, several heat sinks are arranged on the PCB, with the PCB being firmly connected exclusively to these heat sinks. Here, the heat sinks are designed such that they are in direct contact with both the housing section and the metal lid.

Abstract: An anti-lock device for vehicle brakes has a wheel generator which emits pulse-type signals whose frequency is proportional to the rotary speed of the wheel. A counter counts the pulses emitted during each of successive time intervals and these pulses are connected to a first memory which stores the count of the immediate preceding time interval and to a second memory which stores the count of the time interval next preceding the intermediate time interval. A logic circuit then produces a wheel speed value which is based on the wheel speed counts of the immediate preceding and next preceding time intervals.

Abstract: A signal corresponding to the difference between wheel and vehicle speeds is generated when this difference exceeds a first predetermined value and this difference signal is stopped when the difference decreases below a second predetermined value. The difference signal is integrated linearly upwardly until the difference signal decreases to the second predetermined value at which point it is integrated linearly downwardly. An auxiliary signal is generated when the integrated signal is above a third predetermined value. An anti-locking signal is generated in response to the generated difference signal to release the vehicles brakes and this anti-locking signal is continued to be generated until both the difference signal and the auxiliary signal cease and at that point the brakes are again applied.
