Title: 리니어 압축기의 오일 공급장치
Filed: 1998-05-12
Abstract: 본 발명은 리니어 압축기의 오일 공급장치에 관한 것으로, 종래에는 오일의 입출을 규제하는 흡입밸브 및 토출밸브의 크기가 작아 제작 및 조립이 용이하지 못하여 생산성이 저하되는 것은 물론, 상기 흡입밸브 및 토출밸브가 질량체를 지지하는 압축코일스프링에 눌려 고정되어 있으므로, 그 압축코일스프링에 흡입밸브 및 토출밸브의 개폐부가 걸려 오일의 입출을 적정하게 규제하지 못하는 문제점이 있었던 바, 본 발명에서는 통상적인 압축기 유니트의 외곽에 고정 장착되며 일측만 개구되는 오일공급통과, 그 오일공급통의 일부에 연통되어 상기 압축기 유니트의 오일포켓에 연통되도록 오일유로가 형성되는 토출덮개와, 상기 오일공급통 및 토출덮개 사이에 장착되어 오일공급통의 운동방향에 따라 개폐부가 교번되게 구분 동작되는 오일밸브를 포함하여 구성함으로써, 오일의 입출을 규제하는 밸브의 제작성 및 조립성을 용이하게 하여 생산성이 향상됨은 물론, 상기 밸브의 개폐동작중에 그 일부가 여타의 구조물 등에 간섭되지 않도록 하여 압축기의 신뢰성이 저하되는 것을 미연에 방지할 수 있다.

Title: 비밀번호를 이용한 금융관련 현금(신용)카드 및 직불카드 등에 대한 금융사고 및 범죄 예방법
Filed: 1998-05-27
Abstract: 기존의 금융관련 모든 현금(수표)자동지급기 및 창구에서의 현금지급 방식에서 새로운 기계적 변화없이 현재의 씨스템을 고수하면서, 종전 고유의미의 비밀번호와는 다른 추가된 비밀번호의 사용으로 현재 급증하고 있는 금융관련 범죄를 예방하여 손실을 최소화하는 방법임. 
     이는, 사용자가 보다 안심하고 사용하게 되며 동시에 금융사는 사용량의 증대 및 금융상품으로써의 매출증가를 기대할 수 있으므로 금융사의 이익을 증대시킴은 물론 금융사고와 관련된 손실을 없앨 수 있다.    또한 이는 현 씨스템에서 현재 사용중인 현금지급기 등을 전혀 교체할 필요가 없다는 장점이 있다.    비근한 예로 현재 외국등에서 연구되고 있는 지문감식기나 안구감식기 등은 종전의 기계로는 절대 불가능하고 특별한 기계적 장치를 추가로 혹은 교체를 필요로 한다는 점에서 볼 때 막대한 설치자금의 금전적 추가사용이 불가피한 것과는 판이하게 다르다.

In an image displayer having a CCD(Charge Coupled Device), the image inputting section is located in a regular location in the image displaying section. The image inputting section is located in a regular location as one body, when the image displaying section is manufactured. The image inputting section is a photo gate element, and the image displaying section is a liquid crystal display element.

Title: Reflective type lcd
Inventor: KIM SOO MAN
IPC: G02F1/136

Abstract: PURPOSE: A reflective type LCD is provided to obtain a high contrast ratio with a low cost by forming a black paper or a black film instead of a black mask. CONSTITUTION: A polarizer(34) and a color filter layer(33) is formed on a second substrate(22). A thin film transistor(30) is formed on a first substrate(21) and has a gate electrode(26), a gate insulating film(27), a semiconductor(28), a source electrode(25), and a drain electrode(29). A protecting film(31b) is formed on the thin film transistor(30). An irregular layer(31a) is formed on the gate insulating film(27) of a pixel region. A pixel electrode(32) is connected to the drain electrode(27) and is made of a conductive reflecting material. A liquid crystal layer(37) is formed between the first substrate(21) and the second substrate(22). A black paper(35) is formed to a rear surface of the first substrate(21).
