Patent number: 5026469Abstract: An apparatus for holding and turning lenses, particularly for eyeglass lenses to be coated in a high-vacuum vapor deposition or sputtering system. A ring pair carrying the lens to be held is seated on a substrate holder in the process chamber of the high-vacuum system. The substrate holder is a sheet metal part shaped like a half shell, and is rotatable about a vertical axis. A sickle shaped sheet metal blank forms a rake that partially overlaps the substrate holder. The rake is held and guided by a guide ring that is displaceable in the direction of the rotational axis of the substrate holder. The rake is displaceable by a lifting element of a lifting motor secured to the wall of the chamber. The rake includes individual tines having lower edges facing toward the substrate carrier. The tines engage pinions or gear wheels on the individual lens holders. The lens holders are mounted to the substrate via pegs, which allow the lens holders to pivot 180.degree..Type: GrantFiled: December 26, 1989Date of Patent: June 25, 1991Assignee: Leybold AktiengesellschaftInventors: Georg Kunkel, Dieter Klingenstein, Heinz Mahr, Michael Fliedner

Patent number: 4871584Abstract: A very economical process for coating both sides of boards, in particular printed circuit boards, with a liquid coating material, includes the insertion of the boards in a turnover device, wherein first one side is coated, then the board is turned over and the other side is coated. Alternatively, the first side is coated, then the board is turned in a stationary turnover device and its second side is then coated. The process is carried out as follows: 1. Coating the first side of the board. 2. Turning over the board. 3. Coating the second side of the board. 4. Drying both sides together. The board is held or supported during the process by two of its opposite edges.Type: GrantFiled: November 23, 1987Date of Patent: October 3, 1989Inventor: Erich Weber

Patent number: 4817559Abstract: The cup like support of a vacuum vapor deposition apparatus for substrates to be coated comprises a plurality of pivotable support plates each with a plurality of openings for substrate holders. The substrate holders can have a frame partially embracing the substrate received in it in which the substrate sits acted on by a retaining spring and which is attached to the support plate freely tiltable on both sides about a tilting axle. Alternatively at least one of the substrate holders is tiltable and each of the remaining holders is nontiltable having a gripping arm attached at its inner end to a tension providing spring at the edge of an opening in the support plate which is covered by a pair of circular plates. Because of these features a nearly complete fit of the shape of the support to the ideal shape of a cup can be attained by the freely tiltable substrate holders which tilt from the support plate plane to a predetermined angle.Type: GrantFiled: July 30, 1987Date of Patent: April 4, 1989Assignee: Satis Vacuum AGInventor: Delio Ciparisso

Patent number: 4661033Abstract: Wafers are unloaded from a hot wafer processing boat of the type having a plurality of elongated parallel electrodes defining elongated processing gaps therebetween with the wafers being serially spaced apart lengthwise of the gap. A wafer carrier, into which the wafers are to be unloaded from the hot boat, has elongated receiving means, preferably formed by folds of the wafer carrier, extending lengthwise of the elongated electrodes of the boat. The wafer carrier is positioned over the boat and the boat and the carrier are inverted so that the wafers drop from the hot boat into the receiving means of the wafer carrier. In a preferred embodiment, once the wafers have been unloaded onto the folded wafer carrier, the wafer carrier is unfolded to facilitate access to the wafers.Type: GrantFiled: August 22, 1984Date of Patent: April 28, 1987Assignee: Pacific Western Systems, Inc.Inventor: Daniel A.

Patent number: 4551192Abstract: A pinchuck is formed in accordance with this invention by using lithographic techniques to define and to etch a pattern of pins from an extremely flat etchable surface. Since the pins are formed from a surface which is already flat, it is not necessary to level or polish the pins after they are formed. Since lithographic techniques are used, the pin head dimensions, the number of pins, the arrangement of pins, and the density of pins all may be freely chosen without affecting the fabrication cost. By surrounding the region of etched pins with an unetched band, a raised peripheral ring will be formed which can act as a vacuum sealing ring when the pinchuck is used as a vacuum pinchuck. By fabricating the pins from an electrically conductive material (such as doped silicon) and then covering the pins with a dielectric film (such as silicon dioxide), the pinchuck can be used as an electrostatic pinchuck.Type: GrantFiled: June 30, 1983Date of Patent: November 5, 1985Assignee: International Business Machines CorporationInventors: Vincent Di Milia, Juan R.
