Abstract
Description
Claims (3)
- 브라운관의 마스크-프레임 구조체와 패널을 연결하여 지지해 주는 탄성 지지체;상기 탄성 지지체에 부착되어 브라운관 외부에서 진동이 전달될 때 탄성 지지체에 진동을 억제하는 강제력을 제공하고, 접촉 면과 마찰함으로써 진동을 감쇠하는 부재; 로 구성되어 브라운관 새도우 마스크의 진동을 저감하는 모든 마찰 댐핑 구조와 부재 설계 방법;
- 상기 1항에 있어서, 탄성 지지체인 스프링과 접촉하게 하는 방법으로 마찰력을 가함으로써 탄성 지지체의 진동 전달율을 저감 시키는 진동 감쇠 부재를 설계하고 설치하는 방법
- 상기 구조를 가지면서 마찰 계수를 크게 하는 제반 부재의 설계 및 설치 방법;제 1항과 제 2항에 있어서, 마찰 계수를 크게 하기 위하여 탄성 지지체에 덧대는 진동 감쇠 부재의 접촉 표면을 거칠게 만드는 등으로 표면 마찰 계수를 주는 방법으로 진동 감쇠 부재를 설계하고 설치하는 방법
