Granted: 1987-03-23
Abstract: A method to make new polyester was described. Thus, a polyester (viscosity=0.645) contg. 2 wt.% 40m micron-size amorphous silica was mixed with a polyester (viscosity=0.495) copolymerized with 7mol% sulfonate salt at 50 denier/24 filament to give a 3-fibril complex fiber. After the fiber was extended at the rate of 1300m/min at 73≰C, the final product showed the properties of shearing force=3.8g/d, elasticity=28%, and U%=2.4%.

Abstract: The method comprises (a) combining the shadow mask with panel inside on which fluorescent film is not  formed  and  placing  the panel on an exposition stand, (b)  scanning  the  light  stepwise, which passes the beam hole of shadow mask and lands on  the  panel inside, with a photosensor by exposing shadow mask to light, while moving the light source on the exposition stand  stepwise  by  the distance coresponding to the  interval  between  in-line  electron guns, (c) integrating  the  light  information  by  inputting  the scanned light information  into  the  central  computer,  and  (d) driving the plotter by the integrated light information to picture fluorescent film on the panel inside.

Abstract: 본 발명은 반도체 기판의 불순물 제거 방법에 게더링 특히 실리콘 및 화합물 반도체 기판의 이면에 실리콘 이온 주입을 실시하여 결함층을 유발시키므로 기판의 불순물을 제거하는 방법에 관한 것이다. 이를 위하여 본 발명에서는, 반도체 기판의 불순물 제거 방법에 있어서, 반도체 기판의 이면에 소정농도의 실리콘 이온을 전체적으로 주입시켜 기판이 이면을 비정질화 하므로 결함층을 형성하는 것을 특징으로 하는 반도체 기판의 불순물 제거 방법이다.

Abstract: The method for checking the adhesive strength between rubber and metal is characterized in that a minute tube is inserted into a rubber member attached to a metal plate to apply high tension air to the interface between the rubber member and metal plate, and the amount of the air leaked out through the interface is sensed and then is converted into adhesive strength.

Abstract: electrically isolating the elements by mesa-etching the epitaxial growth layer including a cap layer laminated with GaAs layer, AlAs layer and GaAs layer; forming a source and a drain by forming a photoresist pattern and selectively vapor-depositing and heat-treating an ohmic metal layer; forming a depletion gate region by etching GaAs cap layer and an enhancement gate region by etching GaAs cap layer and AlAs cap layer in turn; and forming a depletion gate and enhancement gate by vapor-depositing gate metal on each rigion. The depletion and enhancement gates capable of exactly controlling a threshold voltage is simultaneously formed. Without the depreciation of electrical properties.
