Granted: 1993-08-26
Abstract: e method comprises (a) mixing and agitating  the  fluorescent material and the surface  treating  material  of  SiO2  and  PO43+ derivatives in the presence of alcohol and  organic  solvent,  and (b) calcining the mixture at 200-1000   for 30 minutes to 2 hours. The SiO2 derivatives are SiO2, K2O  SiO2 or Na2O  SiO2. The  PO43+ derivatives are calcium phosphate, sodium  phosphate  or  ammonium phosphate. The method  improves  the  dispersibilty  and  adhesion characteristic of fluorescent material and prevents mesh  blockage and undesirable flow of the material along the  screen  since  the surface treating materials are uniformly diffused into the surface of fluorescent material.

When the "+10" key(K1) is entered, the number "10" is displayed on the display window(1a) and it increases by ten whenever the key is entered. If the number displayed on the tens digit is nine, entering the "+10" key(K1) makes nine as zero. The "up" key(K2) and the "down" key(K3) adds one to and subtracts one from the unit digit, respectively.

Abstract: There is disclosed a rewinding machine for the production of logs(R) of web material (N) without central winding core. It comprises a first winder roller (11) around which the webmaterial is driven and a second winder roller (13) defining, with the first winder roller, a nip (14) through which the web material passes. A member (21) is also provided which is movable relative to the first winder roller (11) and which is cyclically moved toward the surface of said first winder roller with the web (N) between the member (21) and the roller (11) in order to pinch and thus brake the web material between said member (21) and the first winder roller (11), thereby tearing the web and causing the free edge generated by the interruption of the web material to start winding up on itself. <IMAGE>

Abstract: 본 발명은 자동차의 공기저항 특성을 시험하기 위한 것으로, 보다 상세하게는 공기저항을 시험하기 위해 축소제작된 차량모형을 공기를 이용하여 공기저항 특성시험을 하는 대신에 공기보다 저항이 큰 물의 저항을 이용하여 차량모형의 공기저항 특성시험을 함으로써 시험특성을 현저히 개선할 수 있도록 하는 자동차 공기저항 시험용 워터터널 장치 및 그 시험방법에 관한 것이다. 
     이러한 본 발명은 물의 저장과 공급을 하는 메인수조는 공급수조와 워터터널 및 배수수조에 있는 물을 담을 수 있는 크기로 형성되고, 그 바닥에는 컨트롤러와 연결된 공급펌프가 공급파이프로 연결되어 공급수조로 물을 공급하게되며, 공급수조에는 수위감지장치가 형성되고 워터터널로 물을 공급하는 유속발생펌프가 형성되어 유속을 갖는 물이 차단도어를 보유한 터널통로를 통과하여 워터터널로 공급되어 워터터널의 고정반에 설치된 차량모형이 공기방울발생기로부터 발생된 공기방울이 유속에 의해 차량모형 표면에 흐르게 하여 공기저항특성을 육안으로 관찰가능하게 하며, 워터터널을 통과하는 물이 배수수조에 형성된 배수펌프가 배수파이프 연결되어 메인수조로 배수되는 일련의 과정이 순환되어 차량모형을 워터터널에서 물에 의한 공기저항 특성시험을 하게 한 것이다.
