20080197534 | METHOD OF MANUFACTURING SEALED HONEYCOMB STRUCTURE - The manufacturing method of the plugged honeycomb structure for DPF wherein a plugging depth thereof can easily be made uniformly and briefly at low costs. In the method for manufacturing a plugged honeycomb structure having a plugging portion formed in one opening end portion of each of predetermined cells of a cylindrical honeycomb structure including a plurality of cells partitioned and formed into a honeycomb shape by porous partition walls to form fluid passages, holes | 08-21-2008 |
20090011176 | Honeycomb structure and method of manufacturing the same - A tubular honeycomb structure | 01-08-2009 |
20090011180 | PRODUCTION METHOD OF PLUGGED HONEYCOMB STRUCTURE - There is disclosed a plugged honeycomb structure manufacturing method capable of easily manufacturing a plugged honeycomb structure for use in a filter or the like at low costs so that deposits disposed on an end surface of the structure are reduced, a uniform plugging depth is achieved and especially the plugging depth of a slurry-like plugging material at an outer peripheral portion of the honeycomb structure is easily made uniform. In the method of manufacturing the plugged honeycomb structure in which the plugging portion is formed in one opening end portion of each of predetermined cells of a cylindrical honeycomb structure including a plurality of cells divided by porous partition walls to form channels of a fluid in the form of a honeycomb, a flexible porous member | 01-08-2009 |
20090136710 | HONEYCOMB STRUCTURE AND METHOD FOR MANUFACTURING SAME - A honeycomb structure | 05-28-2009 |
20090239031 | PLUGGED HONEYCOMB STRUCTURE - There is provided a honeycomb structure including: porous partition walls separating and forming a plurality of cells extending between two end faces, and an outer peripheral wall formed unitarily with the partition walls. The cells include outermost peripheral portion partial cells each locating in an outermost peripheral portion of the honeycomb structure and having an incomplete cell cross section, a part of which is brought into contact with the outer peripheral wall, and complete cells each having a complete cell cross section other than the outermost peripheral portion partial cells. The complete cells and the outermost peripheral portion partial cells having plugging portions formed on one end portion so that an entire end face of the honeycomb structure shows a checkerwise plugging pattern, and the depth of the plugging portions in the outermost peripheral partial cells is smaller than that of the plugging portions in the complete cells. | 09-24-2009 |

20100242426 | CERAMIC HONEYCOMB STRUCTURE - There is disclosed a ceramic honeycomb structure which is not easily damaged and is excellent in durability even in a case where irregular canning conditions such as an overload and an offset load are generated. The ceramic honeycomb structure has a cell tilt angle of 0.5° or more and 35° or less and a substantially elliptic or oblong sectional shape vertical to a central axis direction. | 09-30-2010 |
20100247853 | CERAMIC HONEYCOMB STRUCTURE - There is provided a ceramic honeycomb structure usable as a catalyst substrate and being improved warm-up properties and thermal insulation properties, and being excellent in exhaust gas purification performance; by employing larger heat capacity and larger thermal conductivity compared with a material of the partition walls in at least one of insides and surfaces of the respective partition walls. | 09-30-2010 |
