Abstract
Abstract A method of fabricating ceramic green sheets with supporting films, in which first and second supporting films 13 and 14 are respectively affixed to both surfaces of a pressure sensitive adhesive double coated tape 12 to construct a supporting member 11, first and second ceramic green sheets 20 and 21 are respectively formed on both surfaces of the supporting member 11, and the first ceramic green sheet 20, along with the first supporting film 13, is stripped from the adhesive tape 12, thereby to obtain the ceramic green sheets 20 and 21 respectively supported by the supporting films 13 and 14.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
94 words
A method of fabricating ceramic green sheets with supporting films, comprising the steps of: preparing a supporting member constructed by affixing supporting films to both surfaces of a longitudinal adhesive tape at least both surfaces of which have adhesive properties; forming ceramic green sheets on said supporting films on both surfaces of said supporting member; and stripping the ceramic green sheet supported by one of the supporting films, along with said one supporting film, from said adhesive tape, thereby to obtain a separated pair of ceramic green sheets supported by the corresponding supporting films.
Claim 2
Independent Claim
94 words
A method of fabricating ceramic green sheets with supporting films, comprising the steps of: preparing a supporting member constructed by affixing supporting films to both surfaces of a longitudinal adhesive tape at least both surfaces of which have adhesive properties; forming ceramic green sheets on said supporting films on both surfaces of said supporting member; and stripping the ceramic green sheet supported by one of the supporting films, along with said one supporting film, from said adhesive tape, thereby to obtain a separated pair of ceramic green sheets supported by the corresponding supporting films.
Claim 3
Dependent Claim
53 words
The method of forming ceramic green sheets with supporting films according to claim 1, wherein said ceramic green sheets are formed on said supporting films on both surfaces of said supporting member by dipping said supporting member in a tank storing a ceramic slurry and pulling the supporting member out of the tank.
Claim 4
Dependent Claim
38 words
The method of fabricating ceramic green sheets with supporting films according to claim 1, wherein said ceramic green sheets are formed on said supporting films on both the surfaces of said supporting member using a doctor blade process.
Claim 5
Dependent Claim
79 words
The method of fabricating ceramic green sheets with supporting films according to claim 1, wherein the pair of ceramic green sheets with the supporting films is obtained by forming said ceramic green sheets on said support films on both surfaces of said supporting member, and then separating said ceramic green sheet supported by one of said supporting films, said ceramic green sheet supported by the other supporting film, and said adhesive tape in said supporting member from each other.
Claim 6
Dependent Claim
39 words
The method of fabricating ceramic green sheets with supporting films according to claim 4, further comprising the step of: winding in a roll shape said ceramic green sheets with the supporting films from which said adhesive tape is stripped.
Claim 7
Dependent Claim
49 words
The method of fabricating ceramic green sheets with supporting films according to claim 4, further comprising the step of: stripping said ceramic green sheets with the supporting films from said adhesive tape, and then continuously feeding the stripped ceramic green sheets with the supporting films to subsequent processing steps.
Claim 8
Dependent Claim
79 words
The method of fabricating ceramic green sheets with supporting films according to claim 2, wherein the pair of ceramic green sheets with the supporting films is obtained by forming said ceramic green sheets on said supporting films on both surfaces of said supporting member, and then separating said ceramic green sheet supported by one of said supporting films, said ceramic green sheet supported by the other supporting film, and said adhesive tape in said supporting member from each other.
Claim 9
Dependent Claim
79 words
The method of fabricating ceramic green sheets with supporting films according to claim 3, wherein the pair of ceramic green sheets with the supporting films is obtained by forming said ceramic green sheets on said supporting films on both surfaces of said supporting member, and then separating said ceramic green sheet supported by one of said supporting films, said ceramic green sheet supported by the other supporting film, and said adhesive tape in said supporting member from each other.
Claim 10
Dependent Claim
38 words
The method of fabricating ceramic green sheets with supporting films according to claim 7, further comprising the step of: winding in a roll shape said ceramic green sheets with the supporting films from which said adhesive is stripped.
Claim 11
Dependent Claim
39 words
The method of fabricating ceramic green sheets with supporting films according to claim 8, further comprising the step of: winding in a roll shape said ceramic green sheets with the supporting films from which said adhesive tape is stripped.
Claim 12
Dependent Claim
49 words
The method of fabricating ceramic green sheets with supporting films according to claim 7, further comprising the step of: stripping said ceramic green sheets with the supporting films from said adhesive tape, and then continuously feeding the stripped ceramic green sheets with the supporting films to subsequent processing steps.
Claim 13
Dependent Claim
49 words
The method of fabricating ceramic green sheets with supporting films according to claim 8, further comprising the step of: stripping said ceramic green sheets with the supporting films from said adhesive tape, and then continuously feeding the stripped ceramic green sheets with the supporting films to subsequent processing steps.
