  • Circuit for load control and method for the emergency operation of an internal combustion engine
    Patent number: 6567740
    Abstract: In the event of a failure or a disruption of an exchange of data between a valve control unit and an operational control unit of an internal combustion engine with electromechanically activated inlet valves, a valve control unit switches over the electromagnetic activation of the inlet valves to full-load control times. The operational control unit suitably sets a throttle valve in order to cause the load control of the internal combustion engine no longer to be performed by the valve load control but rather by the throttle-valve load control in the emergency operating mode.

  • Integrated circuit having at least two vertical MOS transistors and method for manufacturing same
    Patent number: 6566202
    Abstract: An integrated circuit having at least two vertical MOS transistors, and method for manufacturing same, wherein first source/drain regions of the two vertical MOS transistors are located in an upper region of sidewalls of a trench. A second source/drain region is shared by both MOS transistors and is adjacent at a floor of the trench. Gate electrodes of the MOS transistors that are arranged at the sidewalls of the trench can be individually contacted via parts of a conductive layer that are arranged above the first source/drain regions. In a manufacturing method, such arrangement is made possible by the deposition of a conductive layer of doped polysilicon before the generation of the trench. The area of an MOS transistor can amount to 4F2.

  • X-ray detector with an applied stray radiation grid, and method for applying a stray radiation grid to an X-ray detector
    Publication number: 20030089857
    Abstract: In an X-ray detector and method for applying a stray radiation grid onto an X-ray detector having detector elements arranged in a matrix that form a detector surface having detection regions sensitive to X-rays and less sensitive intermediate regions, a basic structure for the stray radiation grid is built up over the detector surface directly on the X-ray detector with a rapid prototyping technique and is subsequently coated or filled with a material that is highly absorbent for X-radiation. An absorbent structure thus arises that lies over the less sensitive intermediate regions of the detector surface. Moiré disturbances are avoided in the X-ray image exposure and the detective quantum efficiency (DQE) is increased.

  • Keyboard
    Publication number: 20030090396
    Abstract: A keyboard includes a plurality of key elements arranged in rows and columns in a matrix-like manner. Each key element has first and second break contacts which are decoupled for safety reasons and are commonly activated when the key element is actuated. An energy supply unit feeds to an evaluation unit electric energy serially via the first break contacts for each separate column and serially via the second break contacts for each separate row. In this way the location of the key element actuation can be reliably ascertained through column and row detection.

  • Heat-resistant housing for electrical function elements and use of such a device for a mobile data memory
    Publication number: 20030089512
    Abstract: A heat-resistant housing (G) for electrical function elements (EB) having a receiving chamber (AK) lying as centrally as possible inside it, a cover block (AD), which is sealed with the receiving chamber (AK), and a receiving block (AB), which is inserted into the receiving chamber and encloses the electrical function elements with a material having a temperature-dependent specific thermal capacity, preferably a high-polymer thermoplastic having low density. In the event of a cyclic interplay of heating and cooling phases, a lower stationery temperature results in the receiving block in the proposed structure in comparison to conventional structures, while the overall weight and volume are nonetheless lower. This is achieved by the high-polymer thermoplastic in the receiving block, which increasingly melts as the temperature rises. The large thermal capacity resulting therefrom acts like a heat sink.
