Abstract: PURPOSE: An apparatus for removing impurity of an optical mask is to remove an organic particle attached on an optical mask using an electrostatic force without applying a mechanical stress. CONSTITUTION: An apparatus(100) for removing impurity of an optical mask comprises: a driving unit including a first driving shaft(112), a first driving motor(114), a second driving shaft(122) and a second driving motor(124); an electrostatic charge medium plate(110) rotated by a driving force of the driving unit, for generating an electrostatic force to remove an organic particle attached on an optical mask; and an electrostatic induction medium plate(120) established rotatively in the opposite direction to the rotation direction of the electrostatic charge medium plate on the electrostatic charge medium plate, for inducing the electrostatic force to the electrostatic charge medium plate. The electrostatic charge medium plate has a circular shape and has a larger diameter than the electrostatic induction medium plate.

Abstract: 광원을 이용한 자물쇠에 사용되는 열쇠로서 빛을 투과하는 열쇠의 본체인 투명체에 휘도 및 명도를 조절하는 물질이나 물체를 내포시키고 고유번호를 나타내는 삽입공에는 빛의차단입자와 반사입자를 삽입한 것으로 열쇠를 구성하므로써 빛의 휘도, 명도, 차단, 반사등에 의하여 열쇠와 자물쇠가 일치하여야만이 자물쇠가 열리므로 훨씬 정밀한 열쇠의 특성을 갖게한 것이다.
