This invention relates to a shade arrangement for a motor vehicle with at least two shades having lengths of shade material (), which are located next to one another and to one end of which a respective pull () is attached. Both of the lengths of shade material () are drawn out and taken up in the same direction at their opposite end from/onto a common roller tube () which is pretensioned in the take-up direction.

Shade arrangement for a motor vehicle

A process and tool for producing a composite body part for a motor vehicle, especially for producing a roof module, the tool having a first tool part and a second tool part which are movable relative to one another. The outer skin is inserted in the first tool part, at least part of the peripheral edge area of the side of the outer skin facing the first tool part being moved into sealing contact with a seal arrangement which is provided on the first tool part, plastic material is applied to the side of the outer skin facing away from the first tool part, the second tool part provision shaping the plastic material, and the composite body part being released from the seal arrangement and removed from the tool.

Process for producing a composite body part for a motor vehicle

An integrated circuit configuration for producing a clock signal includes an integrated inverter connected between an input terminal and an output terminal. A crystal is externally connected to the oscillator circuit. A feedback path of the inverter contains a phase-shifting element which effects a phase shift through 180.degree., so that conditions for oscillation continue to be provided if the crystal breaks.

An integrated circuit configuration has a multiplicity of function units which are connected to one another through a bus. An intermediate memory unit that is activated by a control signal is connected between the bus lines and the respective function unit. The function unit is then connected to the respective bus lines only when it is triggered.

Integrated circuit configuration for reducing current consumption

A Dynamic Memory Access (DMA) control device for transmitting data between a data transmitter and a data receiver via an external bus formed of a data bus, an address bus and a control bus, and has a multiplicity of data transmitters/receivers and at least one microprocessor connected thereto. The transmission of the data in the external bus depends upon a channel program containing channel transfer commands and channel control commands, and includes a central control unit for addressing, dependent upon a channel command, a microcommand, address and control signals corresponding to the microcommand on an internal address-control bus; an address unit is connected to the internal address/control bus and to an internal data bus wherein addresses of a data transmitter, data receiver and the channel program are stored. The address unit delivers an address and simultaneously computes and stores the delivered address; a data unit provides interim data storage; a byte counter unit is connected to the internal data bus and address/control bus for counting the number of bytes to be transmitted; a data transmitting bus interface circuit is connected to the output of the address unit, to the external address bus and to the internal address/control bus, and to the external data bus. A control register is connected to the internal bus for receiving a channel command word, status words and other control information, from which lines for transmitting control signals extend to the central control unit; the units have devices for independently executing the tasks assigned to them.

DMA control device for the transmission of data between a data

Circuit module assembly, includes a circuit module, integrated circuits with a first set of operating characteristics disposed on the module, a bus having a second set of operating characteristics, contact elements connected to the bus for transmitting data, address and control signals. Switchable interface circuits disposed on the module and connected to the integrated circuits are to the contact elements for matching the signals to be transmitted through the contact elements to one of the sets of characteristics.

Device for assigning priorities having a plurality of request channels addressed by request signals, including a plurality of output channels arranged with the request channels in matrix form, each of the request channels being directly connected to one of the output channels and being connected to the respective remainder of the plurality of output channels via a respective switching element controlled by a request signal blocking the appertaining output channels.

Triangular matrix device for the assignment of priorities

An integrated microprogrammed device for controlling information processing cycles, includes a device for generating one or more T-states in dependence on preceding T-states and on given parameters and a method for operating the device.

Integrated microprogrammed device for controlling information processing

Method and apparatus for the error-free synchronization of asynchronous pulses through logical interconnection of the asynchronous pulses with clock pulses of constant frequency by means of a flip-flop, which includes comparing output voltages of the flip-flop with a predetermined threshold voltage for determining a metastable state of the flip-flop, and flipping the flip-flop into a third stable state until the next clock pulse appears if a metastable state is present, for preventing an evaluation of the output voltages of the flip-flop.
