Filed:
Mar 18, 1996
Appl. No.:
8/620741

Assignee:
Thomson Consumer Electronics, Inc. - Indianapolis IN
International Classification:
G03B 4100, G03C 500
US Classification:
430 25
Abstract:
The novel method for producing a coded marking on a CRT faceplate panel having an exterior and an interior surface with a viewing area surrounded by a periphery and having a luminescent screen with a plurality of different light-emitting phosphors separated by light-absorbing material includes the steps of: depositing a suitable photoresist on the interior surface of the panel to form a layer that extends across the viewing area and onto the periphery; illuminating areas of the photoresist on both the viewing area and the periphery with actinic radiation to selectively change the solubility of the photoresist; developing the photoresist to remove the more soluble areas, thereby exposing underlying portions of the interior surface of the panel while leaving retained areas of less soluble photoresist. The retained areas of the photoresist and the exposed portions of the interior surface of the panel are then overcoated with a light-absorbing material which is dried to form a coating. The light-absorbing coating is developed by removing the retained areas of the photoresist having the overlying light-absorbing coating thereon, while leaving the coating of light-absorbing material adhered to the exposed portions of the interior surface of the panel.
Etching A Succession Of Articles From A Strip Of Sheet Metal
US Patent:
4126510, Nov 21, 1978
Filed:
Oct 6, 1977
Appl. No.:
5/840037
Inventors:
John J. Moscony - Lancaster PA
George S. Gadbois - Lancaster PA
George S. Gadbois - Lancaster PA
Assignee:
RCA Corporation - New York NY
International Classification:
C23F 102
US Classification:
156626
Abstract:
When precision etching a succession of articles from a strip of metal having random variations in thickness and moving along a prescribed path, the thickness of the metal strip is monitored, and the etching step is adjusted in response to the monitored thickness to compensate for the thickness variations.
Method And Apparatus For Determining The Average Size Of Apertures In An Apertured Member
US Patent:
3955095, May 4, 1976
Filed:
Oct 4, 1974
Appl. No.:
5/512228
Inventors:
George Simon Gadbois - Lancaster PA
Frank Rowland Ragland - Lancaster PA
Frank Rowland Ragland - Lancaster PA
Assignee:
RCA Corporation - New York NY
International Classification:
G02B 2738
US Classification:
250550
Abstract:
The average aperture width in a small area of an apertured member, such as a shadow mask for a cathode ray tube, is determined by passing a beam of substantially monochromatic light through an area of the member to form an interference pattern, detecting the intensities of at least two light fringes of the interference pattern, generating electrical signals which are representative of the detected intensities and then deriving the average width of apertures in the lit area of the members from the generated signals.
