        박홍채,이윤복,양태영,장윤식,오기동 釜山大學校生産技術硏究所 1997 生産技術硏究所論文集 Vol.53 No.-

        ASEA-SKF 래들에 사용된 고알루미나 내화물의 광물 및 화학적 변화를 화학분석, 현미결관찰, X-선회절분석으로 조사하였다. 미사용 벽돌의 주요 광물상은 α-Al₂O₃, mullite, tridymite이었다. 가동면에서 SiO₂결정상이 소실되었으며 mullite와 α-Al₂O₃가 다소 감소하였고 2FeO·SiO₂와 hercynite, FeO, Cr₂O₃상이 생성되었다. 침식율은 강종에 따라 다소간 차이가 있었으며 용강 SF-45와 60분간 반응시켰을때 SK36벽돌의 침식율은 75.9%인 반면에 SK38벽돌의 침식율은 20.47%이었다. 대부분의 용손벽돌에서 가동면으로부터 내부로 감에 따라 열적 및 화학적 스폴링으로 인하여 미세균열이 존재하였다. Mineral and chemical changes of alumina refractories used in ASEA-SKF ladle were examined by chemical analysis, microscopy and X-ray diffraction method. Main minerals in unused high alumina runner bricks were α-Al₂O₃, mullite and tridymite. In working face of high alumina runner bricks, SiO₂phase was not observed, mullite and α-Al₂O₃phases more or less decreased. On the other hand, 2FeO·SiO₂, hercynite, FeO and Cr₂O₃phases were formed. Th corrosion of high alumina runner bricks showed different behavior by using various types of iron melts. Expecially, corrosivites of SK36 bricks and SK38 bricks, which immersed in SF-45 Iron melts for 60min, were 75.9% and 20.47%, respectively. Microcracks in high alumina runner bricks increased from the working face to the inside due to thermal and chemical spalling.

        본 연구는 cMUT 제작을 위한 미세공정기술을 개발하기 위하여 수행되었다. 이를 위하여 외국의 관련 제조공정 연구결과들을 분석하였다. cMUT 제작의 주요 공정인 미소 진동 박막 형성, 희생층 형성, 식각 공정에 대한 실험을 수행하여 적절한 공정조건을 찾고자 하였다. 각 제작 공정조건들을 변화시켜 가면서 증착된 실리콘 질화막의 두께, 균일도, 잔류응력을 측정하였다. 희생층으로서 실리콘 산화막의 공정조건을 변화시켜 가면서 산화막의 성장률을 분석하였다. 마지막으로 희생층 식각을 위한 최적 식각공정을 얻기 위한 실험을 수행하였다. 본 연구에서 얻어진 주요 미세공정 조건은 추후 cMUT 제작에 적용될 예정이다. The main goal of this study was to develop a micro-fabrication process for the capacitive micromachined ultrasonic transducer (cMUT). In order to achieve this goal, the former research results of the micro-electro-mechanical system (MEMS) process for the cMUT were analyzed. The membrane deposition, sacrificial layer deposition and etching were found to be a main process of fabricating the cMUT. The optimal conditions for those microfabrication were determined by the experiment. The thickness, uniformity, and residual stress of the Si₃N₃ deposition which forms the membrane of the cMUT were characterized after growing the Si₃N₃ on Si-wafer under various process conditions. As a sacrificial layer, the growth rate of the SiO₂ deposition was analyzed under several process conditions. The optimal etching conditions of the sacrificial layer were analyzed. The microfabrication process developed in this study will be used to fabricate the cMUT.

      • Racket 運動時의 反應時間과 運動速度 改善을 爲한 Simulator 「SQT」에 關한 硏究

        허복,蔡鴻遠,李來華,李敏炯,金基學,鄭相澤,朴宇奎 慶北大學校 體育科學硏究所 1986 체육과학연구지 Vol.2 No.-

        The main purpose of this study was to improve greatly the most important reaction time(RT) and speed of movement (SM) at racket exercise by making program for simulator super quality training (S.Q.T) and applying it. The subjects employed were 25 male athletes composed of soccer players 8, volleyball players 7, shooting players 2, soft-tennis players 2, gymnastics player 1, and rugby football player 1 at the Kyungpook National University. We devided each sport player half and half by means of their pre-testing reaction time, and the subjects were devieded into experimental and control group. Experimental group was drilled by using light stimulus simulator training method and control group was drilled by using sound stimulus simulator training method. The training was practiced 20∼30 minutes a day regularly and 5 times a week for 5 weeks. Two groups practiced concentrically experimental learning by using light and sound simulator equipment by S.Q.T. program under equal condition. The propriety on the training effect was investigated by longitudinal analysis of results tested before and after experiment. As the result of the experiment, superiority and inferiority of two groups was evaluated by trying crosssectional analysis. The results obtained were summarized as follows: 1. Reaction time Experimental group; The performance of this group was greatly improved after experiment. Control group; The performance of this group was greatly improved after experiment. Comparison of two groups; Leftward simple completion time showed a significant difference (p<.01), but the other elements did not showed it. As a whole, experimental group was superior to control group, but statistics showed little difference between the two groups. 2. Speed of movement Experimental group; The performance of all elements were improved after experiment(over p<.05). Control group; The performance of this group was improved at only 4 of 9 elements after experiment Comparison of two groups; The performance of service and dash showed a significant difference (p<.01) and the others did not showed it. But as a whole, experimental group was superior to control group in their performance. 3. Viewing Variance and correlation coefficient at the change of RT and SM, there were differences in the variance. This means that the standard deviation is great; i.e. the individual difference is great. The lower correlation coefficient means that correlationship is low in the performance before and after experiment: i.e. it means that individual difference was decreased because the gap of two groups, correlation coefficient became less. Especially, statistics showed that the record of the lower recorded players could be shortened to a maximum.
