Abstract
Abstract A lattice-like ceramic structural body having a cylindrical form in contour and a lattice form in section defined by a pair of parallel wall groups crossing perpendicular with each other is clamped through a damping member by a casing without subjecting a clamping force to portions at which two planes passing through a center line of the structural body and inclined from the wall groups by an angle of about 45°, respectively, are intersected with the outer peripheral wall of the structural body.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
112 words
In a method of clamping a lattice-like ceramic structural body, which is substantially cylindrical in contour and a substantially uniform lattice in section, said lattice having a number of square holes formed by a pair of parallel wall groups crossing perpendicular with each other and extending in lengthwise direction of said structural body, through a damping member by a casing, an improvement which comprises clamping said structural body without subjecting a clamping force to portions at which two planes passing through a center line of said structural body and inclined from said wall groups by an angle of about 45°, respectively, are intersected with the outer peripheral wall of said structural body.
Claim 2
Dependent Claim
112 words
In a method of clamping a lattice-like ceramic structural body, which is substantially cylindrical in contour and a substantially uniform lattice in section, said lattice having a number of square holes formed by a pair of parallel wall groups crossing perpendicular with each other and extending in lengthwise direction of said structural body, through a damping member by a casing, an improvement which comprises clamping said structural body without subjecting a clamping force to portions at which two planes passing through a center line of said structural body and inclined from said wall groups by an angle of about 45°, respectively, are intersected with the outer peripheral wall of said structural body.
Claim 3
Dependent Claim
21 words
A method as claimed in claim 1, wherein in said damping member are provided grooves at positions corresponding to said portions.
Claim 4
Dependent Claim
20 words
A method as claimed in claim 1, wherein in said casing are provided grooves at positions corresponding to said portions.
Claim 5
Dependent Claim
32 words
A method as claimed in claim 1, wherein the thickness of said outer peripheral wall is reduced at positions corresponding to said portions so as to form grooves with said damping member.
Claim 6
Dependent Claim
37 words
A method as claimed in claim 1, wherein said damping member is selected from the group consisting of braided layer of a heat-resistant metallic wire, a ceramic shaped article and a corrugated plate of a heat-resistant metal.
Claim 7
Dependent Claim
33 words
A method as claimed in claim 2, wherein on said outer peripheral wall is provided at least one protrusion so as to prevent rotation of said damping member relative to said structural body.
