Granted: 2001-01-15
Abstract: 투명전극(2a),(2b) 및 배향막(3a),(3b)을 이 순으로 배치한 1쌍의 기판(1a),(1b)이 소정의 간극을 두고 대향배치되고, 상기 간극내에 강유전성 액정(5)이 주입되어 있는 액정소자로서, 이 액정을 스위칭하기 위한 한계치전압이 다른 영역이 미세하게 분포하고 있는 액정소자. 그와 같은 미세분포는 반전(反轉)도메인에 의한 투과율이 25%일 때에 2μmø 이상의 크기의 도메인(마이크로도메인)이 1mm 2 의 시야중에 300개 이상(바람직하기로는 600개 이상)존재하고, 또한 그 도메인내에서의 한계치전압폭이 투과율 10∼90%의 범위에서 2볼트 이상인 것. 
     액정소자 특히 강유전성 액정표시소자에 있어서 고콘트라스트를 유지하면서, 특히 아날로그계조표시를 저코스트로 하여 용이하고도 확실하게 실현하는 것을 목적으로 하는 것이다.

Title: Driving part's load prevention apparatus for low frequence vibrating washing machine
Inventor: KIM JUNG-CHOL
IPC: D06F21/12
Filed: 1993-12-10
Granted: 1996-11-14
Abstract: The apparatus is designed to prevent load of a driving unit of a low frequency vibration washing machine generated by the change of pressure within a confined area under the disc (or a vibrator). The apparatus includes an air flow path (5) located at a washing shaft (5) connected to a disc (1). The apparatus prevents deterioration of a sealer by connecting a confined area and the external air.

Abstract: 주행시에 주차 브레이크를 작동시켜도 주차 브레이크 레버가 록킹되지 않도록 하여 부주의에 의해 주차 브레이크 작동시 대형 사고를 방지할 수 있는 자동차의 주차 브레이크를 제공하는데 그 목적이 있다. 
     이에 따라 주차 브레이크 레버의 작동에 따라 주차 브레이크 케이블이 당겨져 제동작동이 이루어짐에 따라 주차 상태가 보전됨과 아울러 그 상태가 보전되도록 래칫에 래치가 계지되어 주차 브레이크 레버가 록킹되는 자동차의 주차 브레이크 장치에 있어서, 상기한 래치의 일측에 고정 돌기를 마련하여 주행할 때 주차 브레이크 레버의 작동시 래치가 래칫에 계지되지 않도록 하는 록킹 방지수단과; 상기한 록킹 방지수단과 전기적으로 연결됨과 아울러 주차 브레이크 레버의 작동시 온,오프되는 파이롯트 스위치와; 상기한 파이롯트 스위치가 전기적으오 연결됨과 아울러 밧데리 전원과 이그니션 스위치를 개재하고, 차량의 속도에 따라 선택적으로 온,오프되는 스위치 수단을 포함하여 이루어진 구성에 특징이 있다.
