Abstract
Abstract A radiation base of an iron comprises a baseplate, and an injection-molded layer integrally attached to one side of said baseplate, the layer being formed of synthetic resin with low friction properties, nonviscousness and heat resistance, such as polyphenylene sulfide resin, phenolic resin or fluoric resin.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
116 words
A radiation base for an electric appliance, said radiation base comprising: (a) an injection-molded layer formed of a low friction, nonviscous, heat resistant synthetic resin and (b) a metallic base plate integrally attached to one side of said injection-molded layer, said base plate having a plurality of projections formed on the side thereof to which said injection-molded layer is attached to ensure good conjunction between said base plate and said injection-molded layer, said plurality of projections having bulges in their middles, whereby said injection-molded layer protrudes in between the adjacent surface of said base plate and said bulges in said plurality of projections to further ensure good conjunction between said base plate and said injection-molded layer.
Claim 2
Dependent Claim
116 words
A radiation base for an electric appliance, said radiation base comprising: (a) an injection-molded layer formed of a low friction, nonviscous, heat resistant synthetic resin and (b) a metallic base plate integrally attached to one side of said injection-molded layer, said base plate having a plurality of projections formed on the side thereof to which said injection-molded layer is attached to ensure good conjunction between said base plate and said injection-molded layer, said plurality of projections having bulges in their middles, whereby said injection-molded layer protrudes in between the adjacent surface of said base plate and said bulges in said plurality of projections to further ensure good conjunction between said base plate and said injection-molded layer.
Claim 3
Dependent Claim
27 words
A radiation base as recited in claim 1 wherein said synthetic resin is selected from the group consisting of polyphenylene sulfide resin, phenolic resin, and fluoric resin.
