Abstract: A system for analyzing an aluminum deposition process to form a coating on a surface of a CRT faceplate panel disposed on an exhaust cart includes: an apparatus within the exhaust cart for controlling the distribution of the aluminum; a sensor disposed on the panel for determining whether aluminum was deposited thereon, and a plurality of thickness monitors disposed on the panel for generating a plurality of signals representative of the relative thickness of the aluminum coating at a plurality of locations on the surface thereof. The signals are converted into data values to indicate whether the aluminum coating achieves a predetermined thickness profile.A method of depositing the aluminum coating is also disclosed. The method provides an indication of the performance of each of the exhaust carts and permits the categorization of defects for the panels not meeting the predetermined thickness profile.

Abstract: A cathode-ray tube having an electron gun includes a novel cathode sleeve, a heater filament having a heater body with a pair of heater legs disposed within the sleeve and a pair of heater straps attached to the heater legs. The novel cathode sleeve comprises a generally longitudinally extending first portion having a first diameter which conforms closely to the heater body portion of the heater filament for reducing the power requirement thereof, and a second generally longitudinally extending portion having a diameter greater than the first diameter. The second portion has a segment which coaxially encompasses a section of the first portion of the cathode sleeve. The segment of the second portion is connected to the section of the first portion by a reverse drawn transition region which effectively extends the thermal length of the cathode sleeve to minimize the conduction of heat therealong. A plurality of slots may be formed in the transition region to provide heat dams to further limit the heat conduction along the cathode sleeve. The novel cathode sleeve permits the use of a heater having shortened heater legs which terminate within the larger diameter second portion. The heater legs are attached within the second portion to a pair of heater straps accommodated therein, thereby minimizing thermal losses from the heater legs.

Abstract: The present invention relates to a CRT 10 having an evacuated envelope comprising a funnel 11 sealed at one end to a faceplate panel 12 with a luminescent screen 14 on an interior surface thereof. A color selection electrode 16, mounted on a frame 19, is disposed within the envelope in proximity to the screen. An internal magnetic shield 22, is secured to the frame of the color selection electrode, and is spaced from and extends along at least a portion of the funnel. The magnetic shield has a plurality of openings 32 therethrough. An evaporable getter 28 is disposed within the envelope adjacent to the exterior surface 26 of the magnetic shield 22. The magnetic shield is improved by having tabs or louvers 36, 38, 136, 138, associated with the openings, for restricting the deposition of a film of getter material 30 to the exterior surface 26 of the shield 22. In a second embodiment, two magnetic shields 122, 222, with openings 132 and 232, respectively are attached to the frame 19 of the color selection electrode 16. The openings 132 and 232 are non-aligned, thereby restricting the getter film to the exterior surfaces to the two magnetic shields.
