Filed: 1998-09-08
Abstract: 인류사에서 20세기만큼 문명의 급성장을 가져온 시기는 일찌기 없었다.    특히 과학의 발달로 인류는 모든 분야에서 놀랄만한 생활의 혁신을 가져오게 되었다.    또한 의학의 발달로 인간의 수없이 많은 병마도 거의 모두 정복하게 된 것은 모두가 인정하는 바이다.    이에 인류는 좀 더 인간적인 삶, 풍요로운 삶을 위해 전력하고있다.    그러나 가장 근본적인 인간의 오감(五感)의 장애에 대한 해결 방안은 다른 분야의 연구와 성과에 비해 그 정도가 크게 뒤떨어지고, 자연히 오감(五感)의 장애인들에게 인간다운 삶이란 거리가 멀게 느껴지고 있다. 
     이에 사회의 장애인에 대한 관심이 증가되는 것은 사실이나, 그중 시각장애인에 대한 관심과 시각장애인을 위한 장치는 아직도 원시적인 단계를 벗어나지 못하고 있는 형편이다. 
     본 발명은 이러한 시각장애인에 대한 관심과 재고에서 비롯하여 그 문제를 해결하기위하여 고안된 장치이다. 
     본 발명의 주요내용은 광선을 감지못하는 망막의 시신경에 자체 개발한 조명시스템을 가진 광학계의 고안으로 망막에 상(像)이 맺히게 하여 볼 수 있게 하는 장치이다.    또한 이러한 상(像)의 전달은 움직이는 화상을 실시간(real time)으로 망막에 전달할 수 있도록 하는 전자장치(CCD카메라와 LCD판넬 등)가 장착되어 일반정상인이 보는 것과 같이 시각장애인들도 볼 수 있게 하는 것이다. 
     본 발명의 최종목표는 시각장애인들이 일상생활에서도 전혀 불편함을 느끼지않도록 휴대가 간편한 장비를 만드는 것이다. 
     특수 광학계와 특수 조명장치, 그리고 전자장치의 삼일치로 본 발명원리에따른 제품이 실현화 될 것이다. 
     본 발명으로 앞으로 시각장애인은 더 이상 장애인으로 불리워지지 않을 것이다.

Abstract: PURPOSE: An RFQ(radio frequency quadrapole) electrode will have such an optimum configuration as to provide a high power efficiently, an excellent cooling efficiency, a sufficiently strong mechanical strength, and a large beam acceptance. CONSTITUTION: The RFQ electrode (1) which can accelerate a large-current ion beam without causing divergence and is used for an accelerating tube, etc., of a high-energy ion implanter is constituted in such a way that the radius R1 of a beam passing space (9) surrounded by four RFQ electrodes (1) ranges from 5 to 9 mm for a resonance frequency as low as about 33 MHz suitable for heavy ions of B, P, As, etc., and that the electrode has a surface on which crests (3) and valleys (8) are repetitively formed in the forward direction of the beam, with each crest having a radius R2 of curvature of 5 to 9 mm in the direction perpendicular to the axial direction, and a height H which is 4 to 6 times as large as the radius R1 (H/R1:4 to 6) from the bottom of the valley to the top of the crest. When the height H of the electrode is lowered, the shunt impedance increases and the power efficiency is improved, though the cooling performance of the electrode becomes insufficient, because the cross section of a cooling water path cannot be made larger. In addition, such a problem that the electrode tends to vibrate due to an insufficient mechanical strength is apt to occur.
