Abstract: The invention concerns a semiconductor component which can be controlled on the anode side and whose semiconductor body comprises a plurality of adjacent, parallel-connected unit cells having a thyristor structure. A lightly doped n-base region (3) is adjoined on both sides by highly doped p-regions constituting p-base region (2) and p-emitter region (4). The p-base region (2) is followed by a highly doped n-emitter (1) which contacts a cathode electrode (7). Integrated in the p-emitter region (4) is a first n-channel MOSFET (M1) which is connected in series with the thyristor structure by means of a floating electrode (FE). The drain electrode (5b) of the first MOSFET (M1) is provided with an outer anode (8) which has no contact with the p-emitter region (4). A second n-channel MOSFET (M2) is integrated between the n-base region (3) and the drain region (5b) of the first MOSFET (M1).

Abstract: In a fuel tank venting system for a vehicle with an internal combustion engine having an air intake duct and an adsorption filter in which fuel vapors are adsorbed, a venting line extends from the adsorption filter to the air intake duct and includes a regeneration valve, and a bypass line is disposed in parallel with a section of the venting line and includes an air pump for pumping air from the adsorption filter to the air intake duct to provide for venting air flow particularly when the engine is operating under a high load where little vacuum is generated in the air intake duct.

Abstract: The invention provides a sensor system which has a measuring element which has a PT1-action, such as an engine oil temperature sensor for an internal-combustion engine of a motor vehicle. A measured-value analysis unit connected behind the measuring element adds to the measured values supplied by the measuring element a correction value equal to the product of the measuring element time constant and a sliding average change value of the successively sensed measured values.

Abstract: An operating-element arrangement has a user-actuatable operating element which, when actuated in a first actuation direction, brings about an increase in the longitudinal direction of a motor vehicle. When actuated in a second actuation direction opposite to the first direction, the arrangement brings about a reduction in the longitudinal movement of the vehicle. The actuating force exerted on the operating element determines the change in longitudinal movement to be brought about. The rest position of the operating element is displaced in dependence on the longitudinal movement of the vehicle. The user consequently receives a perceptible and/or visible acknowledgement of the respective vehicle speed or of the deviation between the actual and the desired speed. Alternatively, the operating element can be configured isometrically, in that it remains in a fixed position irrespective of the actuating force.

Abstract: In an arrangement for mounting pipe end flanges to the exhaust gas passages of a cylinderhead of an internal combustion engine, the cylinderhead has pockets formed at one side of the exhaust gas passages and the pipe end flanges have projections projecting in opposite directions. One of the flange projections is received in the respective pocket while the opposite one is engaged by a guide strap holding the flange in engagement with the cylinderhead. A gasket and spring structure is disposed between the flange and the cylinderhead for controlling the engagement pressure between the flange and the cylinderhead.

Abstract: An arrangement and method for processing a signal field of sensor signals which originate from the individual sensor elements, for example photodetectors, of a plurality of sensor elements which are regularly spaced in an area and which are each surrounded by six adjacent sensor elements while forming a hexagonal structure. A differential amplifier compares a quantity representing the potential difference and a reference quantity forms a switching quantity (I.sub.Mo) on the output side. A switching comparator, on the input side, receives the switching quantity and, if this switching quantity exceeds the preselectable switching threshold, on the output side emits a switching pulse which causes the "off" switching condition. Four signal outputs 1, 2, 3, 4 as well as four signal inputs (I.sub.M1 I.sub.M2, I.sub.M3, I.sub.

Abstract: In a gasoline internal combustion engine with direct fuel injection a spark plug with a center electrode is mounted in the cylinder top so as to project into the combustion chamber. A mass electrode is disposed on the piston so as to project upwardly into the combustion chamber and is movable with the piston toward and from the spark plug center electrode. An ignition system is provided for timely generating a spark between the spark plug electrode and the movable mass electrode for igniting a fuel/air mixture in the combustion chamber. A fuel injector is mounted in the cylinder top and adapted to provide a cone-like fuel beam with an envelope disposed between the spark plug electrode and the mass electrode such that a spark generated between the two electrodes extends through the fuel injection beam envelope.

Abstract: The invention is a converter-fed drive system having at least one drive motor fed by a converter unit. The converter unit has a valve assembly containing semiconductor valves, a cooler for cooling the semiconductor valves and a capacitor assembly are mounted directly on the drive motor. There is also an inductor assembly, that is electrically connected to the converter unit, but is installed such that it is spatially separated from the converter unit and the drive motor. The cooler is simultaneously used to cool the drive motor as well as the converter unit.

Abstract: A remote control driving mechanism works in the manner of an OR-gate for performing a mechanical switching operation by one of two or more operating control input levers at a time. For this purpose an operable member (2) to be driven is connected to a cam follower (17) which cooperates with two or more cam disks (9, 10) each connected to a respective operating lever (4, 5) through a corresponding push-pull cable (6, 7). Each cam disk (9, 10) has a cam track with a force transmitting section (13, 14) and with a guide section (15, 16) so arranged and configured that the cam follower (17) engages a force transmitting cam track section in one cam disk while engaging a guide cam track section in the other cam disk and vice versa. The sections of each cam track form a U- or V-configuration with a dead point (DP) between the cam track sections. The cam follower (17) is freely movable in the guide track sections, whereby the respective cam disk cannot be operated by its corresponding push-pull cable.

Abstract: An ion current in the combustion chamber of an internal combustion engine is measured by using the spark plug as an ion current sensor. The ignition circuit arrangement has an ignition coil or transformer with a primary winding forming a primary circuit and a secondary winding forming a secondary circuit in which the spark plug is connected. A measuring voltage is applied to the secondary circuit by circuit components forming a measuring circuit for measuring the ion current. The measuring circuit provides a measuring voltage at a value that is lower than the battery voltage of the ignition system or corresponds to the battery voltage at most. A rectifying element is connected to the secondary circuit which feeds the secondary or ignition current into the battery circuit of the ignition system while an ion current caused to flow by the measuring voltage applied to the secondary circuit is measured between sparking times when no ignition current is flowing.

Abstract: A drive unit is composed of an internal combustion engine (1) and of a continuously controllable division gear which comprises a continuously controllable hydrostatic engine/pump unit (4) and a summator gear (10) with subsequent range gears (12, 13) for successive stepup ranges. In order to make this drive unit also possible at operating points within an interval containing the shift points, first the hydrostatic unit (4) is controlled further as far as the shift point, while the engine speed continues to remain constant, the clutch assigned to the next range is then closed and the desired vehicle speed is set by changing the engine speed and is maintained.

Abstract: The invention relates to a method for painting an object during a creative shaping process, for example an injection-molding, extrusion-molding, or back-foaming method with a paint film, as well as a paint film for working the method. In the method, a paint film is placed in an open mold that internally has the original shape of the part. The mold is closed and filled with a starting material, with the starting material curing and/or bonding and/or reacting inside the mold to at least shape the object. To simplify the method, the paint in the paint layer of the paint film is partially cured and/or partially crosslinked before the starting material is added, without adhesive, and is cured only during and/or after the starting material is placed in the mold.

Abstract: A joint for deploying and locking a solar panel or a reflector has a fork which is pivotable through 180.degree. about a common pivot axis with a fixed bearing support. A disk mounted on the fixed bearing support has a sliding curve that terminates in a groove. A latching fork mounted rotatably on pivotable fork has a latching bolt and sliding roller which runs on the sliding curve when the pivotable fork deploys, and together with a latching bolt, engages the groove. A leg spring engages the latching bolt. The sliding curve has a shape such that during the first half of a deployment angle of the fork that is pivoted by the force of a coil spring, a decreasing portion of the coil spring moment is stored in leg spring. In the second half of the deployment angle, a moment 16 stored in leg spring 9 is again added increasingly to the movement, so that during deployment, an approximately constant corrected deployment moment is provided.

Abstract: A motor vehicle exhaust emission control system has two adsorber parts connected in parallel for alternate adsorption and desorption of nitrogen oxides contained in the exhaust from an internal combustion engine and components for conducting further downstream the exhaust that emerges in the adsorber part that is operating at any given time in the adsorption mode and for returning the exhaust that emerges from the other adsorber part that is then operating in the desorption mode, to an intake line of the engine. An oxidizing converter is located upstream of the adsorber part and near the engine for oxidation of the NO contained in the exhaust to form NO.sub.2, so as to permit an increase in the NO.sub.X adsorption rate for the nitrogen adsorber parts.
