Abstract

DC60 (24/02/42) An enclosed device used to control the vaporization of any coating on any substrate, whereby such enclosed device includes at least two enclosed panels (22), one of which is movable, whereby the two enclosed panels (22) hereafter referred for convenience only to the side panels, are of primary co-plane nature and, under the control of a common actuator (23), move continuously between two end positions: a position closed together where the gap (E) between them is minimal and a position separated where the gap (E) between them is maximum. This invention includes anti-reflective coatings for ocular lenses. An enclosed device used to control the vaporization of any coating on any substrate, whereby such enclosed device includes at least two enclosed panels (22), one of which is movable, whereby the two enclosed panels (22) hereafter referred for convenience only to the side panels, are of primary co-plane nature and, under the control of a common actuator (23), move continuously between two end positions: a position closed together where the gap (E) between them is minimal and a position separated where the gap (E) between them is maximum. This invention includes anti-reflective coatings for ocular lenses. It will have a co-planar characteristic, and under the control of a shared actuator (23), it will move continuously between two terminal positions: a closed position where the gap (E) between the two positions is minimal, and a widened position where the gap (E) is maximum. This invention will include anti-reflective coatings for lenses used on the eye.

Claims (24)

1. An obscuration used to control the vaporization of any coating on any substrate whereby the obscuration includes at least two side obscuration panels (22), at least one of which is movable. Such side obscuration panels are essentially coplanar and are rotated around an axis to the substrate (24) to create a third obscuration panel which is fixed by rotation under the control of a shared actuator (23) continuously between two end positions: the closed position where the gap (E) between such side obscuration panels (22) is minimal, and the extended position where the gap (E) is maximum. 2. The covering conforming to claim 1 is of a special nature in which the actuator (23), used in conjunction with both side covering panels (22), includes a movable swing arm (32) on a base (24) which is interconnected with the side covering panels (22) through a buttonhole-like arrangement (33) in which its buttonholes (34) are generally angled to each other. 3. The cover conforming to claim 2 is of the special nature in which the central part of the swing arm (32) is firmly fixed to a nut (35) which is interlocked with a threaded rod (36) that is mounted rotatably on a base (24). 4. The covering conforming to claim 2 is of the special nature in which each of the two side covering panels (22) is removablely attached to the support beams (54) which are rotated around their axis to the base (24) and in which their shared actuator (23) acts through this section. 5. The cover conforming to claim 4 is of a special nature in which buttonholes (34) of an arrangement similar to buttonholes (33) in which swing arms (32) are interlocked with each other to the side cover panel (22) form an opening made in a specific area in the support beam (54) in which the side cover panel (22) is attached and the swing arm (32) supports the pins (55) in a corresponding relationship which are connected into buttonholes (34). 6. The covering conforming to claim 4 is of the special nature that the supporting beams (54) of each of the two side covering panels (22) extend at least partially onto one side of the base (24) and the corresponding side covering panel (22) extend at least partially off the other side of such base (24). 7. Enclosure for maintenance operation for vaporization of the substrate coating on the substrate plate, which contains a rotating support (12) with different positions (14), each position modified to receive the substrate plate (10) to be maintained, an emitter source (13) from which the material to be vaporized, and a cover (16) operating between the support (12) and the emitter source (13), with the special characteristic that the cover (16) is a cover conforming to claim 2. 8. The enclosure for maintenance operations consistent with claim 7 is of a special nature in which the enclosure (16) is essentially parallel to the support (12). 9. The enclosures for maintenance operations in accordance with claim 8 are of a special nature in which the instrument axis (P) of each panel of its side cover (22) is located at a greater distance from the rotation axis (A) of the support (12) than the area on which their common actuators (23) act on them. 10. The enclosure for maintenance operations in accordance with claim 3 is of a special nature in which the enclosure (16) extends in the form of cantilever beams from the fixed attachment (20) which is positioned around the axis of rotation (A) of the support (12). 11. The enclosure for maintenance operations in accordance with claim 7 is of a special nature in which the actuator (23), shared with the side cover panels (22), of both panels of the enclosure (16) is accessible from the outside. 12. The covering conforming to claim 11 is characterized by the fact that both side covering panels (22) are characterized by their importance being parallel to the base (24). 13. The covering conforming to claim 12 is of the special nature in which the covering positions are such that the two side covering panels (22) are in contact with each other at least in specific areas. 14. The covering conforming to claim 13 is of the special nature in which the two side covering panels (22) touch only at one point in the area of the corner (62), and the space (E) between them is bordered all around, forming a triangle in total. 15. The covering conforming to claim 1 is of the kind in which it has a plane of symmetry with respect to which the two side covering panels (22) move relative to each other in opposite directions. 16. A method for fabricating a multilayer coating for maintenance of a set of base plates (10) by vacuum vaporization, in which the base plates (10) are placed in a vacuum vaporization maintenance enclosure (11) which contains a cover (16) of the characteristic that the cover (16) is a cover with a variable surface area in accordance with Requisition 1 and the surface area of the cover (16) is modified to create the deposition of individual layers. 17. The process consistent with claim 16 is of a special nature in which the coating consists of different layers so that the result of the maintenance of the base plate (10) is an anti-reflective maintenance. 18. The process consistent with claim 16 is characterized by the coating consisting of at least two distinct layers of different materials. 19.
