Patent number: 6403039Abstract: 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.Type: GrantFiled: May 10, 1999Date of Patent: June 11, 2002Assignee: Emitec Gesellschaft fuer Emissionstechnologie mbHInventors: Rolf Brück, Wolfgang Maus

Patent number: 6393922Abstract: 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.Type: GrantFiled: July 29, 1999Date of Patent: May 28, 2002Assignee: Infineon Technologies AGInventor: Jürgen Winterer

Patent number: 6388271Abstract: The power semiconductor components in prior art high-voltage smart power ICs frequently take up more than half of the total chip surface. To be able to produce the ICs more economically, the material consumption must be reduced, and hence, in particular, the surfaces of the drift zones of the power semiconductor components must be made significantly smaller. Based on the premise that the electrical breakdown field strength of silicon carbide is approximately ten times higher than that of silicon, the parts of a semiconductor component which receive voltage are integrated in silicon carbide. The drift zone can be made much smaller for the same reverse voltage. In an SiC MOS transistor with lateral current conduction, the SiC layer, which is only approximately 1-2 &mgr;m thick and is covered by an SiO2 layer, is arranged so as to be dielectrically insulated on an Si substrate. Two n+-doped SiC regions are used as source and drain contacts.Type: GrantFiled: March 10, 2000Date of Patent: May 14, 2002Assignee: Siemens AktiengesellschaftInventors: Heinz Mitlehner, Michael Stoisiek
