    摘要： This invention provides a plugging method, for a ceramic honeycomb body, that does not create clearance in plug members closing cell end portions. To produce a ceramic honeycomb body 5 having a large number of cells 55 partitioned by partitions 51 and cell end portions 50 plugged by plug members, end faces of the ceramic honeycomb body are immersed in a plug member slurry 1 while the cell end portions 50 not provided with the plug member are covered with a masking material 90, and are then dried and heated. The plug member slurry 1 contains ceramic particles, a foaming material and water or an oil solvent.

    摘要： A filter catalyst is for purifying exhaust gases emitted from internal combustion engines and including particulates, and includes a wall-flow honeycomb structure (1) and an upstream-side straight honeycomb structure (2). The wall-flow honeycomb structure (1) includes inlet cells (10) clogged on the downstream side of the exhaust gases, outlet cells (11) neighboring the inlet cells (10) and clogged on the upstream side of the exhaust gases, filter cellular walls (12) demarcating the inlet cells (10) and the outlet cells (11) and having pores, and a catalytic layer (13) formed on the surface of the filter cellular walls (12) and/or the surface of the pores of the filter cellular walls. The upstream-side straight honeycomb structure (2) is disposed on the upstream side of the exhaust gases with respect to the wall-flow honeycomb structure (1), is provided integrally with the wall-flow honeycomb structure (1), and includes upstream-side straight cells (20) in which the exhaust gases flow straight, and upstream-side cellular walls (21) demarcating the upstream-side straight cells.

    摘要： A honeycomb structure for particulate filter comprising at least one main honeycomb structure (10) and sub-honeycomb structures (21,22) axially disposed, in series, on both end surfaces of the main honeycomb structure (10). Partial plugs (15) are constituted for some of the cells (11) of the main honeycomb structure (10) by facing the intersecting portions of partitioning walls (211), surrounding the cells of the sub-honeycomb structure (21) disposed adjacent to the main honeycomb structure with some of the cells of main honeycomb structure, and the arrangement of the partial plugs (15) at one end surface (101) of the main honeycomb structure differs from that at the other end surface of the main honeycomb structure (10).
