    • The present invention relates to a coating method for the preparation of a coated nuclear fuel. Particularly, the present invention relates to the coating method of nuclear fuel surface with more than two coated layers of carbides, borides or nitrides and their compounds comprising deposition or permeation steps of i) elements or mixture that can form carbides, borides or nitrides and ii) a layer of pyrolytic carbon or boron prepared by chemical vapor deposition(CVD) or sputtering in sequence or in reverse sequence, or nitrogen prepared by gas permeation in sequence, on the nuclear fuel surface. The coated layers are formed with carbides, borides, nitrides or their mixture at high temperature and pressure by a combustion synthesis. The coating method of this invention can be applied to various types of nuclear fuels either in particle or in pellet type and control and preserve fine crystal structure without phase transition since the surface of nuclear fuel coated with pyrolytic carbon and silicon is heated only for several seconds by heat source such as laser beam, arc or microwave. Thus, the present invention is excellent method of coating nuclear fuel surface not only for particle type fuel which used in High Temperature Gas-cooled Reactor (HTGR) but also for pellet type fuel used for Water-cooled Reactors.
    • 本发明涉及一种涂覆核燃料的制备方法。 特别地,本发明涉及具有多于两个碳化物,硼化物或氮化物涂层的核燃料表面的涂覆方法及其化合物,其包括沉积或渗透步骤,i)可形成碳化物,硼化物或氮化物的元素或混合物,以及ii )通过化学气相沉积(CVD)或溅射按顺序或反向顺序制备的热解碳或硼的层,或通过气相渗透制备的氮在核燃料表面上。 涂覆层通过燃烧合成在高温和高压下由碳化物,硼化物,氮化物或它们的混合物形成。 本发明的涂布方法可以应用于颗粒或颗粒型的各种类型的核燃料,并且控制和保存没有相变的精细晶体结构,因为涂覆有热解碳和硅的核燃料的表面仅被加热几秒钟 通过激光束,电弧或微波等热源。 因此,本发明不仅用于高温气冷堆(HTGR)中使用的颗粒型燃料,而且用于水冷反应堆的颗粒型燃料,也是涂覆核燃料表面的优良方法。

    • There is provided an electronic paper display device and a manufacturing method thereof. The electronic paper display device includes a first electrode formed of a transparent material; at least one or more second electrodes disposed to face the first electrode with differing gaps therebetween; and at least one or more display units disposed between the first and second electrodes and having optical properties varied according to voltage applied to the first and second electrodes. The display units are disposed between the first electrode and the second electrodes disposed to face the first electrode with differing gaps, so respective rotation amounts or rotation angles of the display units become different when the same magnitude of voltage is applied. Accordingly, a wide range of contrast levels is displayed.

    • In an electro-motion type automatic clip-ejecting apparatus, when paper to be bound is inserted into the apparatus after a large number of clips are charged in the clip magazine, each clip is simultaneously ejected from the clip magazine so that a binding operation is performed so that it is possible to conveniently use the clip ejecting apparatus by only one hand of the user. The apparatus includes a wheel movement member and a clip ejecting member. The wheel movement member includes a pole, a spring for providing elastic force, and a pole movement bar for performing a linear movement so that the pole movement bar is interlocked with the pushing rack gear. The pole is interlocked with the pole movement bar according to linear movement of the pole movement bar. The clip ejecting member includes a spar gear, a fixed gear, and a pushing rack gear.
