摘要: A particulate trap for a diesel engine use which is less likely to vibrate or deform under exhaust pressures and achieves good results in all of the particulate trapping properties, pressure drop, durability and regenerating properties. This trap has a filter element made of plurality of flat or cylindrical filters. Longitudinally extending exhaust incoming and outgoing spaces are defined alternately between the adjacent filters by alternately closing the inlet and outlet ends of the spaces between the adjacent filters. Gas permeable reinforcing members are inserted in the exhaust outgoing spaces to prevent the filter from being deformed due to the difference between the pressure upstream and downstream of each filter produced when exhausts pass through the filters. Similar gas permeable reinforcing members may also be inserted in the exhaust incoming spaces or at both ends of the filter element to more positively prevent vibration of the filters.

摘要: A particulate trap for use with a diesel engine is high in particulate trapping capacity and regenerating capacity and low in pressure drop, and yet is compact and inexpensive. This trap has a filter element made up of a plurality of tapered filter members formed from a fabric of heat-resistant metal fibers. The filter members have different diameters from each other and are nested concentrically one inside the other so that the adjacent filter members are positioned inversely. Each filter member is connected at its large-diameter end to the small-diameter end of the immediately outer filter member to alternately close the exhaust inlet and outlet ends of the gaps between the adjacent filter members. The filter element thus formed is mounted in a metal case provided in an exhaust line and used as a particulate trap. With this arrangement, it is possible to increase the particulate trapping area of the filter and the exhaust inlet openings without increasing the size of the entire trap. Such a trap is less likely to suffer pressure drop and is highly durable.

摘要: A particulate trap for a diesel engine in which at least two nonwoven sheets made of heat-durable metallic fibers and at least two corrugated plates made of heat-durable metal having a width smaller than that of the nonwoven sheets are alternately overlaid in the thicknesswise direction with each other in a spiral manner, and one surface of one of the nonwoven sheets and one surface of the other of the nonwoven sheets are in close contact and are continuously welded to each other along the upstream edges thereof as seen from the flowing direction of the exhaust gas so that a first space closed along the upstream edges and opened along the downstream edges is formed between the nonwoven sheets via one of the corrugated plates, and the other surface of the one nonwoven sheet and the other surface of the other nonwoven sheet are in close contact and are continuously welded to each other along the down stream edges thereof as seen from the flowing direction of the exhaust gas so that a second space closed along the downstream edges and opened along the upstream edges is formed between the nonwoven sheets via the other of the corrugated plates, is disclosed. In the particulate trap, the difference in width between the nonwoven sheet and the corrugated plate is larger in a central zone of the particulate trap than in the circumferential zone thereof.

摘要: A method and resulting structure for constructing an IC package utilizing thin film technology. The package has a bottom conductive plate that has a layer of ceramic vapor deposited onto the plate in a predetermined pattern. Adjacent to the insulative layer of ceramic is a layer of conductive metal vapor deposited onto the ceramic. The layer of metal can be laid down onto the ceramic in a predetermined pattern to create a power plane, a plurality of signal lines, or a combination of power planes and signal lines. On top of the layer of conductive material is a lead frame separated by a layer of insulative polyimide material. The polyimide material has a plurality of holes filled with a conductive material, which electrically couple the layer of conductive material with the leads of the lead frame. The power and ground pads of the integrated circuit are connected to the layer of vapor deposited conductive material and conductive plate, which are also coupled to the corresponding leads of the lead frame, thereby connecting the IC to the leads of the lead frame. The signal pads of the IC are connected to the lead frame and/or signal lines formed within the layer of vapor deposited conductive material. The IC and attached circuit package can then be encapsulated in a plastic shell.
