Appeal No. 93-2172
Application 07/363,758
46. The glass plate of claim 45, wherein the thickness of
the layer is between about 1800 to 4500 Angstroms.
47. The glass plate of claim 46, wherein the electrical
properties of the layer comprise an emissivity of less than or
equal to 0.15 and a resistivity of 3 x 10 ohm-cm or less.-4
59. A plate of glass coated with a pyrolyzed metal oxide
layer comprising indium and tin oxides formed by depositing a
predetermined amount of a mixture of an organic indium compound
and a tin compound on a heated substrate, thereby pyrolyzing the
mixture.
The sole reference relied upon by the examiner is:
King et al. (King) 4,006,070 Feb. 1, 1977
The appealed claims stand rejected for obviousness (35
U.S.C. § 103) over King.
We reverse the rejection as to claims 37 and 51. We affirm
the rejection as to claims 43-50 and 52-66.
The subject matter on appeal is broadly directed to a glass
plate coated with a layer of indium oxide or indium and tin
oxides formed by pyrolyzing organic indium and/or tin compounds
on a heated glass substrate. Layers formed by the pyrolyzing
process have a low emissivity and good electrical conductivity.
As set forth in dependent claim 47 on appeal, the electrical
