  • Patent number: 6403039
    Abstract: A catalytic converter for a small engine and a method for manufacturing the same include a honeycomb body coated with catalytically active material and made from at least partly structured layers of sheet metal with channels for the passage of exhaust gas. In order to reduce manufacturing costs, the honeycomb body is placed in a silencer housing disposed in the proximity of the engine, in such a way that at least a predominant portion of exhaust gas of the small engine has to flow through the honeycomb body. The honeycomb body is a layered, wound or folded stack of sheet metal layers, which is squeezed into the silencer housing, plastically deforming at least 10% and preferably 20 to 30% of the channels, so that it completely fills at least a partial volume of the housing.

  • Patent number: 6395454
    Abstract: The invention relates to an integrated electric circuit comprising a metal layer provided with a passivation layer. The passivation layer is made of a monomolecular film which is placed on the surface of the metal layer. The monomolecular film is formed prior to contacting the metal layer with metal wires. The wires are pushed through the passivation layer with a force strong enough to pierce the monomolecular film. In the alternative, the film may be selectively removed at defined locations in preparation for the contacting with the wires.

  • Patent number: 6396678
    Abstract: A capacitor having a signal electrode connected to a signal conductor, a ground electrode connected to a ground conductor and a dielectric disposed between the two. In the capacitor, delay-time-dependent limits are moved to higher frequency ranges in order to extend the applicability in the frequency range. This is accomplished by the signal conductor or the ground conductor being spaced apart from the signal electrode or the ground electrode and thus from the dielectric having a high dielectric constant. The signal conductor or the ground conduct is subdivided into at least two conductor regions that are separated in the direction of signal propagation. Each of the conductor regions is electrically connected via at least one conductor connector to the signal conductor or to the ground conductor, respectively.

  • Patent number: 6393922
    Abstract: The invention relates to a pressure sensor component comprising a base body and a pressure connection element. The base body comprises a chip carrier, onto which a semiconductor chip with an integrated pressure sensor is mounted. Contact is made with the semiconductor chip by means of connection, which are routed laterally out from the base body. The base body is open on one side, and the opening is bounded by side parts of the chip carrier. The pressure connection element is placed onto the upper end regions of the side parts. The invention is distinguished by the fact that the filler, with which the inner space of the base body is filled and the semiconductor chip is covered, is simultaneously used to connect and seal the pressure connection element and the base body. The ends of the pressure connection element are preferably configured in such a way that the filler is drawn by capillary forces into the interspace between side parts and pressure connection element.

  • Patent number: 6396802
    Abstract: The invention relates to a data transmission method in which the data to be transmitted are divided into a plurality of subchannels each with a normal component and a quadrature component that is orthogonal to the normal component. The divided data are transmitted in different frequency bands. The frequency bands are arranged with non-equidistant frequency spacings between one another. An error signal is generated at the reception end for each subchannel both for the normal branch and for the quadrature branch and fed to a corresponding reception filter.

    Abstract: Nitrate ions are removed from a solution. Such a solution is, in particular, a spent decontamination solution or another spent solution intended for reducing the radioactivity of a metal part. It is provided that the solution, if it comprises a short-chain organic compound, is irradiated with UV light. Otherwise, such a compound is introduced into the solution prior to irradiation.

  • Patent number: 6386645
    Abstract: A method for the controlled power activation of an electromechanical braking system in a motor vehicle where the maximum power available is less than the nominal capacity includes the step of activating brake force-generating units of the braking system individually or in subgroups in succession to one another. The brake force-generating units are in each case activated with a power level corresponding to a portion of the maximum power available. The portion of the maximum power available is sufficient for the individual unit to function at least partially.
