  • Operating circuit for discharge lamps with switchable operating states
    Patent number: 6181074
    Abstract: A circuit for operating a discharge lamp wherein a variable representing an operating state of the lamp is stored in an operating state storage device. A changeover device switches over between a plurality of operating states of the lamp. The operating state storage device is activated by each relatively short interruption of power to the operating circuit and switches over to an operating state other than that represented by the stored variable. A timer circuit separate from the operating state storage device is coupled to the voltage supply terminal of the operating state storage device and defines a specific time for distinguishing relatively long interruptions of the power supply from relatively short ones.

  • Electric drive unit with a bush having different diameters
    Patent number: 6177742
    Abstract: An electric drive unit, for windshield wipers of a motor vehicle, including a drive motor, having an armature accommodated in a substantially cup-shaped pole housing, and including a gearbox, secured by a face end to the pole housing for receiving at least one worm, wheel supported on a power takeoff shaft. The worm wheel engages a worm connected to an armature shaft of the drive motor. The power takeoff shaft is supported in an eccentric bush which is rotatable to set the axial spacing between the armature shaft and the power takeoff shaft and can be mounted in the rotated state, in a manner fixed against relative rotation, in the gearbox. The eccentric bush is embodied in a graduated fashion, such that it has a larger diameter on a side toward the flange than on another side remote from the flange.

  • Plate valve for the dosing of liquids
    Patent number: 6173912
    Abstract: In a plate valve, particularly a cone spray valve, the valve gap, or respectively, seal gap (6) which is present in the open condition is not designed with parallel faces, but with cross-sectional areas which remain the same given increasing radius. This approach applies to a set from the interior outward. The advantage consists in the avoidance of cavitation and in the achievement of a low closing force for sealing the valve.

  • Dynamic semiconductor memory device and method for initializing a dynamic semiconductor memory device
    Patent number: 6175531
    Abstract: A dynamic semiconductor memory device of the random access type having an initialization circuit which controls the switch-on operation of the semiconductor memory device and of its circuit components. The initialization circuit supplies a supply voltage stable signal once the supply voltage has been stabilized after the switching-on of the semiconductor memory device. The initialization circuit has an advance detector circuit, which detects a predetermined level state of an externally applied clock control signal chronologically before the supply voltage stable signal is generated and, as a reaction to this, supplies a first enable signal for unlatching the control circuit provided for the proper operation of the semiconductor memory device.

  • Method and apparatus for locating and isolating a fault within a token ring network
    Patent number: 6175553
    Abstract: A method and an apparatus for isolating a communication fault within a token ring network are described. The token ring network includes a number of stations, each of which is configured to generate or repeat beaconing data indicating a network communication fault. The method requires firstly isolating each station of the token ring network in a closed-loop station ring. A location in each of these isolated station rings is then monitored for the transmission of beaconing data indicating a communication fault within the respective station ring. If the transmission of such beaconing data is not detected, the station is reconnected to the token ring network. On the other hand, should the transmission of such beaconing data be detected, the station is maintained within the closed-loop station ring. In this way, faulty stations are isolated from the token ring network.
