Abstract

Abstract A transreflector is made by forming a series of spaced parallel stripes of a conductive material on one surface of a synthetic resin carrier film. The film is placed against the surface of a mold defining the desired concave internal curve for the transreflector, and the mold cavity is closed by placing over the film in spaced relationship a second mold half having the desired convex external curve for the transreflector. A fluid synthetic resin is introduced into the mold cavity to form the desired transreflector element with spaced parallel stripes disposed on the internal concave surface thereof. The carrier film is removed from the transreflector element with the conductive material stripes remaining on the transreflector element.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 106 words
In a method for making a transreflector, the steps comprising: (a) depositing on one surface of a synthetic resin carrier film a series of spaced parallel stripes of a conductive material; (b) placing said film on the surface of a mold defining the desired concave internal curve for the transreflector; (c) assembling over said film in spaced relationship a second mold half having the desired convex external curve for the transreflector, said halves providing a mold cavity; and (d) introducing a fluid synthetic resin into said mold cavity to form the desired transreflector element with said spaced parallel stripes disposed on the internal concave surface thereof.
Claim 2
Dependent Claim 106 words
In a method for making a transreflector, the steps comprising: (a) depositing on one surface of a synthetic resin carrier film a series of spaced parallel stripes of a conductive material; (b) placing said film on the surface of a mold defining the desired concave internal curve for the transreflector; (c) assembling over said film in spaced relationship a second mold half having the desired convex external curve for the transreflector, said halves providing a mold cavity; and (d) introducing a fluid synthetic resin into said mold cavity to form the desired transreflector element with said spaced parallel stripes disposed on the internal concave surface thereof.
Claim 3
Dependent Claim 35 words
The method of making a transreflector in accordance with claim 1 including the step of removing said synthetic resin carrier film from said transreflector element, while said conductive material stripes remain on said transreflector element.
Claim 4
Dependent Claim 27 words
The method of making a transreflector in accordance with claim 1 wherein each of said stripes comprises a multiplicity of closely spaced lines of said conductive material.
Claim 5
Dependent Claim 19 words
The method of making a transreflector in accordance with claim 1 wherein said conductive material is a metallic deposit.
Claim 6
Dependent Claim 21 words
The method of making a transreflector in accordance with claim 1 where said resin of said carrier film is a polyester.
Claim 7
Dependent Claim 37 words
The method of making a transreflector in accordance with claim 5 wherein said fluid synthetic resin is a low loss, low dielectric constant polymer selected from the group consisting of polyesters, polymethyl pentenes, polyacrylates and styrene interpolymers.
Claim 8
Dependent Claim 21 words
The method of making a transreflector in accordance with claim 1 wherein said transreflector element is of generally circular peripheral configuration.
Claim 9
Dependent Claim 23 words
The method of making a transreflector in accordance with claim 1 including the step of assembling said transreflector element with a retaining element.
Claim 10
Dependent Claim 26 words
The method of making a transreflector in accordance with claim 8 wherein said retainer element is a ring engaged with the periphery of said transreflector element.
Claim 11
Dependent Claim 30 words
The method of making a transreflector in accordance with claim 1 wherein the step of depositing the conductive material on the carrier film comprises physical vapor deposition of a metal.
Claim 12
Dependent Claim 31 words
The method of making a transreflector in accordance with claim 1 wherein the step of depositing the conductive material on the carrier film comprises depositing an ink having conductive particles therein.
