Appl. No.:

09/775228

Inventors:

Steven William Haun - Landisville PA
Gary Lee Diven - Lancaster PA
Joseph Arthur Reed - York PA

Assignee:

Thomson Licensing S. A. - Boulogne Cedex

International Classification:

F16M 100

US Classification:

248636, 181207, 313402, 313407

Abstract:

A split foot damper for damping vibrational energy on a tension mask having a border with an edge. The apparatus has a first element having a first portion in moveable contact with a surface of the border and a second portion in moveable contact with the edge of the border, and a second element having a third portion in moveable contact with the surface of the border and a fourth portion in moveable contact with the edge of the border, where the two elements are connected to each other at a point that is affixed to the surface of the border. As the mask vibrates, the vibrational energy is transferred to the split foot damper, wherein vibrational energy is dissipated as the portions of the split foot damper makes contact against the surface and edge of the border.

US Classification:

313402, 313407

Abstract:

An apparatus for maintaining tension in a mask frame of a cathode ray tube. The apparatus includes affixing a shadow mask to a pair of triboxes disposed along opposite sides of a mask frame at a predetermined tension. The triboxes are coupled to the mask frame by braces having a different coefficient of thermal expansion than the triboxes so as to compensate for the expansion of the frame during thermal cycling of the cathode ray tube. Consequently, it is possible to maintain the tension force applied to the shadow mask by the mask frame.

International Classification:

H01J 2907

US Classification:

313407, 313404

Abstract:

The invention relates to a tension mask frame for a CRT having a generally rectangular support frame to which a peripheral portion of a tension mask is attached. The support frame has at least a long side and a short side. One side extends along an outer edge of the mask and protrudes inward toward the outer edge of the mask. The short side is attached to the long side to form a closed corner portion between the long side and short side of the support frame. The closed corner portion is used to suspend the mask within a panel portion of the color cathode ray tube.

US Classification:

313405, 313402, 445 30

Abstract:

An apparatus and method for retaining a damper wire used in a cathode ray tube to reduce vibration in the grill type mask assembly of a cathode ray tube. The damper wire is retained across a grill type mask by a bimetal damper spring having a first end and an opposing second end. The second end is coupled to the frame of the grill type mask assembly. A tab located proximate the first end of the damper spring is adapted to accept the damper wire that traverses the mask.

US Classification:

Abstract:

A measuring head of the present invention conveys light from an external source through at least one optical fiber to at least one respective plane mirror inside the measuring head, where the light reflects through and is collimated by at least one collimating lens so as to be incident on a sample, in one embodiment, at an angle of substantially 45 degrees. The resulting optical path is folded once and thereby allows enough virtual space to redirect the light without excessive bending of the fibers. Light diffused from the sample is, in one embodiment, perpendicularly collected by a focusing lens, focused on the end of another optical fiber and directed outside of the measuring head to be used, for example, by a measuring instrument for the spectral analysis of the collected light.
