Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
124 words
A vapor source holding container for the evaporation, by heating, of an evaporative material in said container, said container comprising: an opening smaller in size than the surface area of said evaporative material, a first wall portion at the bottom of said container which is in contact with said evaporative material, and a second wall portion, connected to said first wall portion and said opening, wherein said second wall portion is not in contact with said evaporative material, wherein the emissivity of at least the external surface of the first wall portion of said container in contact with the material is lower than the emissivity of at least the external surface of the second wall portion that is not in contact with the material.
Claim 2
Dependent Claim
124 words
A vapor source holding container for the evaporation, by heating, of an evaporative material in said container, said container comprising: an opening smaller in size than the surface area of said evaporative material, a first wall portion at the bottom of said container which is in contact with said evaporative material, and a second wall portion, connected to said first wall portion and said opening, wherein said second wall portion is not in contact with said evaporative material, wherein the emissivity of at least the external surface of the first wall portion of said container in contact with the material is lower than the emissivity of at least the external surface of the second wall portion that is not in contact with the material.
Claim 3
Dependent Claim
39 words
A vapor source holding container according to claim 1 wherein the first wall portion laterally abuts the remaining wall portion and includes an interior surface having generally the same emissivity as the external surface of said first wall portion.
Claim 4
Dependent Claim
50 words
The vapor source holding container according to claim 1 wherein the first wall portion includes an interior surface portion having generally the same emissivity as the external surface of the second wall portion and wherein the external surface of the first wall portion is composed of a low emissivity material.
Claim 5
Dependent Claim
33 words
The vapor source holding container according to claim 3 wherein the external surface of the first wall portion includes low emissivity material which is attached to the outside of the internal surface portion.
Claim 6
Dependent Claim
25 words
The vapor source holding container according to claim 3 wherein the external surface of said first wall portion includes a coating of low emissivity material.
Claim 7
Dependent Claim
35 words
The vapor source holding container according to claim 1 wherein the emissivity of the first wall portion is not more than 0.4 and the emissivity of the second wall portion is not less than 0.7.
Claim 8
Dependent Claim
34 words
The vapor source holding container according to claim 3 wherein the first wall portion is composed of a material selected from mirror-grinding-treated Al, brass, Cr, Cu, Au, Fe, Mo, Ni, Pt, Ta and W.
Claim 9
Dependent Claim
94 words
A vapor source holding container for the evaporation by heating of an evaporative material in said container comprising: a first wall portion generally defining the area for contact with the evaporative material; a remaining wall portion connected to the first wall portion to form said container; an opening in the remaining wall portion for emitting the vapor of the evaporative material, the opening being smaller in area than the first wall portion; wherein the external surface of the first wall portion has a lower emissivity than the external surface of the remaining wall portion.
Claim 10
Dependent Claim
94 words
A vapor source holding container for the evaporation by heating of an evaporative material in said container comprising: a first wall portion generally defining the area for contact with the evaporative material; a remaining wall portion connected to the first wall portion to form said container; an opening in the remaining wall portion for emitting the vapor of the evaporative material, the opening being smaller in area than the first wall portion; wherein the external surface of the first wall portion has a lower emissivity than the external surface of the remaining wall portion.
Claim 11
Dependent Claim
39 words
A vapor source holding container according to claim 8 wherein the first wall portion laterally abuts the remaining wall portion and includes an interior surface having generally the same emissivity as the external surface of the first wall portion.
Claim 12
Dependent Claim
50 words
The vapor source holding container according to claim 8 wherein the first wall portion includes an interior surface portion having generally the same emissivity as the external surface of the remaining wall portion and wherein the external surface of the first wall portion is composed of a low emissivity material.
Claim 13
Dependent Claim
41 words
The vapor source holding container according to claim 10 wherein the external surface of the first wall portion includes a piece of low emissivity material which is attached to the outside of the internal surface portion of the first wall portion.
Claim 14
Dependent Claim
25 words
The vapor source holding container according to claim 10 wherein the external surface of the first wall portion includes a coating of low emissivity material.
Claim 15
Dependent Claim
35 words
