Filed: 1999-08-31
Abstract: 본 발명은 스케이트의 원리를 이용하여 최소한의 부력으로 사람을 수면위에 부상시켜 자유롭게 이동할 수 있게끔 하는 기구이다.

     이를 위하여 본 발명은 최소의 필요한 부력의 확보를 위해 부력과 내구력이 강한 소재로 표면을 처리하고 내부공간을 최대로 확장, 수소 또는 헬륨을 주입하기 위한 튜브를 삽입한 부력판을 제작하였으며 부력판 하단 부에 수직으로 앞에서 뒤까지 이어지는 저항판을 부착한다. 또한 부력판의 앞쪽을 '선체'의 앞 부문과 같이 최소의 마찰과 아울러 속도에 따른 부력의 효과를 낼 수 있게끔 제작하였다. 
     정지 시 신체가 약간 물에 잠긴 상태에서 부력판 하단에 부착된 저항판 옆면 전체로 스케이트 지치듯 물을 차내면서 그 반동력으로 신체의 중심을 앞으로 옮기며 미끄러지듯이 이동하게 된다. 전진을 하게 되면 선체의 모양과 같이 제작된 부력 판 앞쪽 곡면부위에 물과의 마찰로 인해 기구는 수면위로 상승하게 되고 차낸 발은 물 밖으로 나와 앞으로 이동하면서 전진했던 발이 다시금 물을 차내 속도를 가속시킨다.

Abstract: PURPOSE: A method for washing an electronic material is provided not to generate a roughness of a substrate surface, and to remove a pollution such as dopants stuck on the surface in a wet washing processed in an industry handling the electronic material such as a silicon substrate for a semiconductor. CONSTITUTION: A washing process under the vibration of supersonic waves is performed with a washing liquid of resolution directly or by passing a super pure rinsing process after a washing process with a washing liquid of oxidation. The washing method is suitable to a bare silicon substrate of semiconductor, and the roughness of substrate surface is prevented. Because the process with the washing liquid of oxidation is performed, the surface of the silicon substrate is oxidized before the washing process with the washing liquid of resolution under the vibration of supersonic waves. Therefore the boundary face of silicon/silicon oxide film is not damaged in the other washing process, and the roughness of the electronic material(the silicon substrate) is not increased after the washing process.
