Abstract:
The method for installing filament improves the stability of filament by eliminating torsion and compressive stress caused by carburization and thermal expansion of filament. The method comprises: (A) maintaining two parallel electrodes(5a, 5b) at constant distance; (B) installing the filament(1) between the electrodes; and (C) installing the supporter(6) in the middle of gas feeder(2) and filament to prevent the filament hanging down.
Abstract:
manufacturing a number of diamond layers having slant edges on a substrate with a diamond chemical vapor deposition by using a slant mask; arranging the diamond layers on a substrate mount whose temperature is adjustable in a cross stripes form; and adding a reduction salt of an oxygen-acetylene torch to the borders of the diamond layers so as to unite the diamond layers.

본 발명은 다이아몬드 합성용 고온 필라멘트 화학증착장치의 필라멘트 설치방법에 관한 것이다. 본 발명은 고온 필라멘트 화학증착장치의 가동시 탄화나 열팽창에 의해 필 라멘트의 길이 변화가 발생하여 초래되는 필라멘트의 길이변화를 흡수하기 위한 방편으로 전극사이에 설치되는 필라멘트의 양측단부중 적어도 일측의 결합부가 전극에 대해 상대적인 슬라이딩이 가능하도록 필라멘트를 설치하는 방법에 기술적 특징이 있다. 본 발명의 필라멘트 설치방법은 탄화나 열팽창에 의한 필라멘트의 길이변화가 흡수되어 필라멘트에 압축응력을 가하지 않기 때문에 뒤틀림등의 악영향을 배제할 수 있어 필라멘트의 안정화를 기할 수 있다는 효과가 있다.

Abstract:
The present invention relates to a Se or S based thin film solar cell capable of improving the crystallinity and the electrical property of an upper transparent electrode layer by controlling the structure of a lower transparent layer in a Se or S based light absorption based thin film solar cell, and a method for fabricating the same. In a Se or S based thin film solar cell according to the present invention which is a Se or S based thin film solar cell having a light absorption layer and a front transparent electrode layer, the front transparent electrode layer comprises a lower transparent electrode layer and an upper transparent electrode layer. The lower transparent electrode layer comprises an oxide based thin film (impurity-doped Zn-Mg based oxide thin film) where the mixed oxide of Zn oxide and Mg oxide is mixed with an impurity element.
