A honeycomb filter includes cell walls and cells. The cell walls extend along a longitudinal direction of the honeycomb filter to define the cells between the cell walls. The cells have first cells and second cells each having a substantially square shape in a cross-section perpendicular to the longitudinal direction. The first cells are sealed and the second cells are open at one end face of the honeycomb filter. The substantially square shape of the first cells includes a first side whose extended line intersects a second side except for corner portions of the substantially square shape of the second cells. The second side and the extended line of the first side are substantially perpendicular.

Honeycomb filter and method for producing the honeycomb filter

A honeycomb filter includes an outer wall having a substantially cylindrical shape and a central axis of the substantially cylindrical shape, first walls provided at an inner side of the outer wall and extending along the central axis, and second walls provided at the inner side of the outer wall and extending along the central axis. The first walls and the second walls substantially perpendicularly cross to define cells having a substantially square shape in a cross-section perpendicular to the central axis. A thickness of the outer wall in the cross-section at a first intersection between the outer wall and a first diameter substantially parallel to the first walls in the cross-section and a thickness of the outer wall in the cross-section at a second intersection between the outer wall and a second diameter substantially parallel to the second walls in the cross-section are largest.

A ceramic filter assembly having improved exhaust gas processing efficiency. The ceramic filter assembly () is produced by adhering with a ceramic seal layer () outer surfaces of a plurality of filters (F), each of which is formed from a sintered porous ceramic body. The seal layer () has a thickness of 0.3 mm to 3 mm and a thermal conductance of 0.1 W/mK to 10 W/mk.

A table for a wafer polishing apparatus having superior heat-resistant, anti-thermal-shock, and anti-abrasion characteristics and capable of increasing the diameter of a semiconductor wafer while improving the quality of the wafer. The table () includes a plurality of superimposed bases () each of which is formed of silicide ceramic or carbide ceramic. The bases () are joined together by an adhesive layer (). A fluid passage () is formed in a joining interface between the bases ().
