The partition walls are less prone to deformation and crack formation due to thermal stress.

摘要： A honeycomb heater having integrally formed and/or integrally sintered electrodes constructed of a metallic honeycomb structure having a desired honeycomb configuration, and metallic electrodes which are integrally sintered with the honeycomb structure at predetermined positions thereon. The honeycomb heater having integrally sintered electrodes is manufactured by joining or contacting the electrode-like formed bodies to the formed honeycomb body, and then by sintering the formed honeycomb body with the electrode-like formed bodies attached or contacted thereto. The electrodes are made of the same material as that of the honeycomb body, or of a material having an electric resistance lower than that of the material comprising the honeycomb body. Alternatively, the honeycomb heater having integrally formed and integrally sintered electrodes is manufactured by preparing an extrusion of a honeycomb body as one body which has a honeycomb configuration and an electrode-like shape at predetermined positions thereon, and then sintering that formed honeycomb body.

摘要： The catalytic converter includes a first flow passage for an automotive exhaust gas and a second flow passage disposed parallel to the first flow passage to bypass the exhaust gas therethrough. The first flow passage contains a honeycomb heater or a heater catalyst which comprises a honeycomb heater with a catalyst carried thereon. At the beginning of an operation of any engine, the exhaust gas whose temperature is low is caused to flow through the first flow passage. When the temperature of the exhaust gas exceeds a predetermined value, the flow passage is switched from the first passage to the second flow passage.

摘要： A honeycomb structure for fluid filtration includes a support of porous ceramic material having a multiplicity of axially parallel passageways extending therethrough and uniformly spaced by porous partition walls to permit flow of fluid under pressure passing therethrough and a selective membrane coated onto the surface of the passageways to separate one or more components from the fluid and to permit flow of filtrate passing therethrough to be carried through the porous partition walls to the exterior surface of the partition walls for collection. In the honeycomb structure, the partition walls are formed to permit the passage of filtrte at a flow quantity more than twenty times the flow quantity of filtrate passing through the selective membrane and partition walls, and an average pore size of the selective membrane is about from 10 to 10000 angstroms.
