Method Of Detecting The Vaporization Of Getter Material During Manufacture Of A Crt
Method Of Detecting The Vaporization Of Getter Material During Manufacture Of A Crt
US Patent:
4445872, May 1, 1984
Filed:
Jan 18, 1982
Appl. No.:
6/340526
Inventors:
James G. Ottos - Lancaster PA
Assignee:
RCA Corporation - New York NY
International Classification:
H01J 942
US Classification:
445 3
Abstract:
In a method of vaporizing getter material from a getter container inside a vacuum electron tube, light from the vaporization is sensed at least from the outset of the heating of the container. A time-dependent sample signal is produced from the sensed light which is compared with time-dependent criteria related to the vaporization, and a characteristic of the vaporization is derived from the comparison.
Apparatus And Method For Automatically Aligning A Multibeam Electron Gun Assembly With A Cathode-Ray Tube Bulb
Apparatus And Method For Automatically Aligning A Multibeam Electron Gun Assembly With A Cathode-Ray Tube Bulb
US Patent:
4189814, Feb 26, 1980
Filed:
Sep 5, 1978
Appl. No.:
5/939497
Inventors:
James G. Ottos - Lancaster PA
Assignee:
RCA Corporation - New York NY
International Classification:
H01J 918
US Classification:
29 2516
Abstract:
An electrode of the electron gun assembly has two accurately positioned alignment apertures therein, a line connecting the centers of the alignment apertures being transverse to the central longitudinal axis of the gun assembly. The alignment method includes holding the electron gun assembly relative to the cathode-ray tube envelope and directing a collimated light source toward the alignment apertures. Next, the position of the electron gun assembly is rotationally stepped about its central longitudinal axis while the light source is pulsed in coordination with the steps in position of the electron gun assembly. During the rotation, the number of light pulses passing through the alignment apertures are counted up. Thereafter, the stepping direction of the electron gun assembly is reversed and the number of light pulses passing through the alignment apertures are counted down. The reverse rotation of the electron gun assembly is stopped when the number of counted down light pulses are half of the maximum number of light pulses counted up.
Method Of Detecting Heater Resistance Independent Of Contact Resistance
Method Of Detecting Heater Resistance Independent Of Contact Resistance
US Patent:
4020416, Apr 26, 1977
Filed:
May 20, 1976
Appl. No.:
5/688475
Inventors:
James Gunard Ottos - Lancaster PA
Assignee:
RCA Corporation - New York NY
International Classification:
G01R 2714
US Classification:
324 64
Abstract:
A constant current is applied through a heater by means of an electrical connector which mates with terminal pins of the tube. The applied current causes a voltage across the heater. A first voltage measurement is made across the heater at a first time. After a predetermined time interval has elapsed, a second voltage measurement is made across the heater. The value of the first voltage measurement is substracted from the value of the second voltage measurement and the value of the difference obtained is compared with a predetermined reference value. If the difference value is less than the reference value, a first nominal value of heater resistance is indicated. If the difference value is greater than the reference value, a second nominal value is indicated. The nominal heater resistance values are detected independent of the electrical connector contact resistance.
