PURPOSE: A rear-transmission type screen only for an LCD(Liquid Crystal Display) projector is provided to offer a screen having compatibility of a screen for a CRT(Cathode Ray Tube) type projector, as well as a screen for an LCD projector by displaying clear definition of middle/large screens without having screen distortion, moire, ghosts, damage of definition and color changes. CONSTITUTION: Polyethylene is heated by steam from a steamer up to 80deg.C and then put into cooling water to obtain the liquid state molten by benzole peroxide. The liquid type material is poured into a glass frame used as a mold, and a glass frame is put thereon to form a casting type. Herein, the glass frame is processed in protrusion form after obtaining desired color by carbon. To adjust the thickness, the edge of the material is packed and fixed to the corner of the mold by a clip(24). The material is put into a heating tank(20) filled with water(26) and heated at a primary demanded temperature of 90deg.C for about 10h. Then, the material is heated secondarily by steam of 120deg.C for about 2h. The material is cooled at ordinary temperature and separated from the casting mold. The material is produced into a rear-transmission type screen. The screen has compatibility of screen for a CRT type projector and a screen for an LCD projector by displaying clear images.

PURPOSE: A construction method of a bridge abutment is provided to overcome difficulties on installing an anchor according to the usage of many reinforcing bars even though an earthquake-resistant plan is applied to the construction of a bridge. CONSTITUTION: A construction method of a bridge abutment comprises the steps of; forming a bearing wall(210) covering a bed plate on the upper part of a pier(200); fitting the bed plate to a space(220) covered by the wall; and injecting mortar a gap between the bed plate and the space.
Abstract:
본 고안은 교량의 상단 보나, 건축구조물의 상·하부 중간에 설치되어, 안정되게 하중을 지지하는 탄성 패드에 관한 것으로, 다수의 실린더홈(11a,11b)이 형성된 상판(11)과, 다수의 실린더홈(12a,12b)이 형성된 하판(12), 상판(11)과 하판(12)의 실린더홈(11a,12a;11b,12b)에 각각 안착되는 다수의 탄성부재(14a,14b,14c,14d), 상판(11)과 하판(12)의 실린더홈(11a,11b,12a,12b)에 양쪽 선단이 각각 삽입되어 실린더홈(11a,11b,12a,12b)에 안착된 탄성부재(14a,14b,14c,14d)를 밀봉하는 피스톤(13a,13b) 및, 상판(11)과 하판(12) 사이에서 피스톤(13a,13b)을 수용하면서 일체 성형되는 탄성보강재(15)로 이루어진 구조로 되어, 슬라이딩시 감쇄현상이 발생되면서 팽출현상을 구속하므로 보다 큰 하중을 지지하여 안전성이 향상되고, 보다 폭 넓은 활용이 가능하면서 시공비용이 감소되도록 된 것이다.
Abstract:
PURPOSE: A method and an apparatus are provided to remove mode noise by applying vibration having a predetermined period to an apparatus subject to laser ray scanning, an apparatus for reflecting laser ray or a screen where images are projected. CONSTITUTION: Vibration means(30) is mounted to a laser scanning apparatus(240 to vibrate a part where laser ray is generated. Vibration means(32) is mounted on a reflecting mirror(22) to vibrate a part which reflects the scanned laser ray to a screen(20), a separate space or a display. Vibration means(34,36) mounted to the screen(20) vibrate a part which indicates the laser ray which is reflected from the reflecting mirror(22) or directly scanned from the laser scanning apparatus(24).
Abstract:
본 발명은 산업 폐기물을 처리하기 위한 소각 설비 및 소각 방법에 관한 것으로서, 폐기물을 급동결시켜 냉동 분쇄기로 분쇄하여 분말 상태로 만든 다음 비닐이나 플라스틱과 같은 분말은 원자재로 재활용 할 수 있고, 재활용이 되지 않는 나머지 폐기물 분말은 소각로에서 소각하며, 소각할 때 발생하는 재와 그을음을 제거한 후 매연은 유해가스를 제거하여 대기 중으로 방출한다. 이러한 상기 목적을 달성하기 위해 본 발명에서는 냉동기(1)를 사용하여 동결실(2)에서 폐기물을 -80∼-90℃로 급동결시키는 공정, 동결된 폐기물을 3대의 냉동 분쇄기(16a,16b,16c)를 거쳐 분말로 만드는 공정, 소각로(11)에 상기 폐기물 분말을 투입하여 순식간에 소각하는 공정, 매연 처리시설인 침전실(14)을 사용하여 소각할 때 발생하는 재와 그을음을 제거하는 공정, 산 처리장치(15)를 사용하여 매연에 포함된 황산이나 질산과 같은 유해가스를 제거하는 공정으로 폐기물 분말을 처리함으로써, 본 발명에 따른 폐기물 소각 방법 및 소각 설비는 산업 폐기물에 의한 환경오염을 현저히 줄이면서도 많은 양의 폐기물을 처리할 수 있는 특징을 가지고 있다.
