    摘要： An object of the present invention is to provide a filter that makes it possible to suppress the initial pressure loss and, also, to reduce the rising rate of the pressure loss that increases as particulates accumulate; therefore, the pressure loss at the time when a prescribed amount of particulates have been collected becomes lower, and the pressure loss from the viewpoint of the period up to the recovery as a whole also becomes lower. The present invention provides a filter, which is a column shaped filter having a honeycomb structure, including a number of through holes that are placed in parallel with one another in the length direction with wall portion interposed therebetween, wherein the through holes are constituted by two types of through holes, that is, large-capacity through holes having a relatively larger cross-sectional area in the cross section perpendicular to the length direction and small-capacity through holes having a relatively smaller cross-sectional area in the cross section, with the numbers of the two types of through holes being substantially set to the same, the large-capacity through holes are sealed at one end of the filter, while the small-capacity through holes are sealed at the other end of the filter, and supposing that the ratio (a/b) of the total (a) of lengths of wall portion which is shared by one large-capacity through hole and the adjacent large-capacity through hole in the cross section perpendicular to the length direction and the total (b) of lengths of wall portion which is shared by one large-capacity through hole and the adjacent small-capacity through hole in the cross section perpendicular to the length direction is defined as a and that the ratio (A/B) of the area (A) of the cross section of the large-capacity through hole and the area (B) of the cross section of the small-capacity through hole is defined as β, α and β satisfy the relationship represented by the following formula (1): β≧(20/9) α2+1 (where 0

    摘要： A honeycomb structural body having a plurality of cells and partition walls defining the cells, wherein a cross-section of each partition wall perpendicular to the flow direction of a fluid to be permeated has a grille shape of which gratings cross in x axis and Y axis directions, and there are at least two kinds of cells different in their cross-sectional areas perpendicular to the flow direction of a fluid to be filtered by virtue of changing intervals of the partition walls in the x axis direction and/or intervals of the partition walls in the y axis direction, as predetermined. Each cell is defined by two parallel partition walls having the same length and another two parallel partition walls having the same length crossing each other and being formed at the predetermined intervals. A die usable for forming such a honeycomb structure is also disclosed.

    摘要： A device for treatment of exhaust gases includes a housing; a fragile structure resiliently mounted within the housing; and a non-intumescent mounting mat disposed in a gap between the housing and the fragile structure. The mounting mat comprises melt-formed, leached glass fibers high in silica content and exerts a minimum holding pressure for holding the fragile structure within the housing of one of (i) at least 10 kPa after 1000 cycles of testing at a hot face temperature of 900null C., a gap bulk density of between 0.3 and 0.5 g/cm3, and a percent gap expansion of 5 percent, and (ii) at least 50 kPa after 1000 cycles of testing at a hot face temperature of 300null C., a gap bulk density of between 0.3 and 0.5 g/cm3, and a percent gap expansion of 2 percent.
