CONSTITUTION: An optical cable(50) is inserted into a cap(40) and a clamp(30) in sequence. Many ribbon tubes(24) are inserted into an aligning hole(23) and fixed with an adhesive. An extension fiber(51) of the cable is inserted into a fixing groove(21), and many ribbons of optical fiber extended from the cable are inserted to the ribbon tube, which is coupled to a branching part(20), to be branched. The branching part is helically linked to a coupling part(12) of a housing(10) after fixing the center extension fiber and the branching device with a special adhesive. If the cap is tightened to the clamp after linking the cap to a coupling part(13) of the housing helically, a tightening part(45) of the cap is tapered on an inclined face(35) of the clamp as well as shrinking the clamp toward the center line so an outer sheath(52) of the cable is fixed tightly.

Abstract: 다이아몬드가 합성 다이아몬드의 층을 그 위에 갖는지 여부를 시험하기 위하여, 다이아몬드는 높은 에너지를 갖는 자외선 방사선이 조사되어 발광을 야기하여, 다이아몬드의 다른 영역에서 만들어지는 발광 강도가 측정 및 비교된다. 한 실시예에서는 일체함(15)이 사용되었고 다이아몬드(13)는 회전 가능한 장착대(14) 위에 장착된다.
