  • Color cathode-ray tube with shadow mask having attached vibration attenuator
    Patent number: 6608433
    Abstract: A vibration attenuator is attached to a shadow mask in a movable condition without being adhered to the shadow mask. The vibration attenuator has depressions, and is attached to the shadow mask by inserting its foot portions through holes provided in the shadow mask, and folding them at the depressions, thereby deforming the vibration attenuator into an approximately rectangular shape. Because a vibration energy of the shadow mask is consumed by friction due to a contacting or sliding of the vibration attenuator with the shadow mask, vibration of the shadow mask can be attenuated effectively with a simple structure.
