Abstract
Abstract A microphotocomposing apparatus for making artworks is intended for use in microelectronics. The apparatus comprises a precision coordinatograph for displacing a photographic plate, a highresolution projecting lens, and a device for forming a pattern in the object plane of the projecting lens. The device for forming the pattern includes two changeable master artworks and a lens disposed intermediate of the master artworks; the lens is used to align the patterns of both master artworks in the object plane of the projecting lens. In operation, a pattern is projected onto the photographic plate which is being displaced, the shape and size of the pattern being varied by a mutual displacement of the master artworks.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
186 words
A microphotocomposing apparatus for making artworks, comprising: a photographic plate displaceable in two mutually perpendicular directions in its own plane; a projecting lens; a light source operatively associated with said projecting lens; means for forming a pattern in the object plane of said projecting lens, which pattern is projected onto said photographic plate, including two mutually displaceable master artworks disposed intermediate of said light source and said projecting lens, the patterns thereof being aligned in the object plane of said projecting lens so that a pattern obtained as a result of aligning the patterns of both master artworks is projected onto said photographic plate, said means for forminG a pattern in the object plane of said projecting lens including an intermediate lens disposed intermediate of said master artworks, a first of said two master artworks being in the object plane of said projecting lens and a second of said master artworks being in the object plane of said intermediate lens so that the pattern of said second master artwork is transferred by said intermediate lens to the plane of the pattern of said first master artwork.
Claim 2
Dependent Claim
186 words
A microphotocomposing apparatus for making artworks, comprising: a photographic plate displaceable in two mutually perpendicular directions in its own plane; a projecting lens; a light source operatively associated with said projecting lens; means for forming a pattern in the object plane of said projecting lens, which pattern is projected onto said photographic plate, including two mutually displaceable master artworks disposed intermediate of said light source and said projecting lens, the patterns thereof being aligned in the object plane of said projecting lens so that a pattern obtained as a result of aligning the patterns of both master artworks is projected onto said photographic plate, said means for forminG a pattern in the object plane of said projecting lens including an intermediate lens disposed intermediate of said master artworks, a first of said two master artworks being in the object plane of said projecting lens and a second of said master artworks being in the object plane of said intermediate lens so that the pattern of said second master artwork is transferred by said intermediate lens to the plane of the pattern of said first master artwork.
Claim 3
Dependent Claim
50 words
A microphotocomposing apparatus as claimed in claim 1, wherein, to reproduce groups of similar pattern elements on said photographic plate, both said master artworks have patterns in the form of screens with similar transparent polygons, the arrangement whereof determines the pattern of periodically repeated elements on the artworks being produced.
Claim 4
Independent Claim
207 words
A method of reproducing curves and lines inclined to the direction of displacement of a photographic plate, using an apparatus comprising: a photographic plate displaceable in two mutually perpendicular directions in its own plane; a projecting lens; a light source operatively associated with said projecting lens; means for forming a pattern in the object plane of said projecting lens, which pattern is projected onto said photographic plate, including two mutually displaceable master artworks disposed intermediate of said light source and said projecting lens, the patterns thereof being aligned in the object plane of said projecting lens so that a pattern obtained as a result of aligning the patterns of both master artworks is projected onto said photographic plate, said method comprising the steps of: employing a pair of master artworks each having patterns in the form of transparent circles; aligning said master artworks so that projected on the photographic plate is a slot formed by the segments of two circles, the width of the slot determining the thickness of the line being reproduced; and continuously displacing the master artworks and the photographic plate so that the major axis of symmetry of the slot is always in line with the direction in which the photographic plate is displaced.
Claim 5
Independent Claim
207 words
A method of reproducing curves and lines inclined to the direction of displacement of a photographic plate, using an apparatus comprising: a photographic plate displaceable in two mutually perpendicular directions in its own plane; a projecting lens; a light source operatively associated with said projecting lens; means for forming a pattern in the object plane of said projecting lens, which pattern is projected onto said photographic plate, including two mutually displaceable master artworks disposed intermediate of said light source and said projecting lens, the patterns thereof being aligned in the object plane of said projecting lens so that a pattern obtained as a result of aligning the patterns of both master artworks is projected onto said photographic plate, said method comprising the steps of: employing a pair of master artworks each having patterns in the form of transparent circles; aligning said master artworks so that projected on the photographic plate is a slot formed by the segments of two circles, the width of the slot determining the thickness of the line being reproduced; and continuously displacing the master artworks and the photographic plate so that the major axis of symmetry of the slot is always in line with the direction in which the photographic plate is displaced.
Claim 6
Dependent Claim
149 words
A microphotocomposing apparatus for making artworks, comprising: a photographic plate displaceable in two mutually perpendicular directions in its own plane; a projecting lens; a light source operatively associated with said projecting lens; means for forming a pattern in the object plane of said projecting lens, which pattern is projected onto said photographic plate, including two mutually displaceable master artworks disposed intermediate of said light source and said projecting lens, the patterns thereof being aligned in the object plane of said projecting lens so that a pattern obtained as a result of aligning the patterns of both master artworks is projected onto said photographic plate, wherein to produce a composite artwork, one of said master artworks has a set of standard topological layouts, and the other of said master artworks is provided with a rectangular transparent window through which any of said patterns may be projected onto said photographic plate.
