摘要： A gas duct includes a ceramic honeycomb structure includes a metal case, a ceramic honeycomb structure accommodated in the metal case, and a holding member placed between the outer surface of the ceramic honeycomb structure and the inner surface of the metal case. The holding member has, at the two ends, to-be-connected areas engageable to each other and is wound round the outer surface of the ceramic honeycomb structure in such a way that the to-be-connected areas of the two ends are engaged to each other and that the connected area and its vicinity face the partition wall of each cell constituting the honeycomb structure. In the gas duct, even when the ceramic honeycomb structure has thin partition walls, the honeycomb structure is not broken when it is accommodated in a metal case, i.e. during the canning.

摘要： A ceramic honeycomb catalytic converter having a novel canning structure capable of stably retaining a thin-walled ceramic honeycomb catalyst within a metal casing for a long period. A retainer member in the form of a ceramic fiber mat is disposed between an inner peripheral surface of the casing and an outer peripheral surface of the honeycomb catalyst, in a compressed state to generate a surface pressure for retaining the honeycomb catalyst in place. The ceramic fiber mat is composed of heat resistant and non-intumescent ceramic fibers, and has a compression characteristic which is substantially free from a significant increase or decrease over an operative temperature range of the catalytic converter. The casing may be provided with at least one locking member for locking the ceramic fiber mat in a flow direction of exhaust gas passed through the honeycomb catalyst.

摘要： A ceramic honeycomb filter for purifying exhaust gases from combustion engines includes a ceramic honeycomb structure formed by extruding and having a number of through-passages alternately closed at their ends by ceramic closure members. The through-passages formed by partition walls for capturing fine particles in the exhaust gases accumulated on the partition walls. The ceramic honeycomb filter comprises porous ceramic layers provided on the partition walls over a distance of 1/10-8/10 of an effective length of the filter from outlet ends of said through-passages for the exhaust gases.
