Title: Signal transmission circuit using a circuit which generates a variable standard voltage
Inventor: CHOE YUN-HO
IPC: G08C19/00
Filed: 1989-06-13
Granted: 1992-06-26
Abstract: The circuit  includes  a  first  delaying  device  (101)  for delaying the input signals of  a  main  clock  terminal  (100).  A comparator (201) compares the output of the first delaying  device (101) with a reference signal to supply its  output  to  a  driver (301), and a second delaying device (302) receives the  output  of the comparator (201).  A  variable  reference  voltage  generating circuit (40) outputs a reference voltage in response to the output of the second delaying device (302), thereby  driving  the  driver (301) at a high speed by means of the output signals of  the  main clock terminal (100). With the circuit, the RC delay is minimized, for high speed transmission.

Abstract: B형 간염 백신을 경구용으로 개발하기 위하여, 소장점막을 통한 침입경로를 가지는 소아마비 바이러스를 운반체로 사용하였다. 약독화된 소아마비 바이러스는 현재경구용으로 사용되고 있는 매우 안전한 바이러스이다. 
     높은 면역성을 유발시키기 위해서는 B형 간염 바이러스의 표면항원 및 프리에스 항원이 소아마비 바이러스에서 형질 발현되어야 하고, 이를 위해서는 B형 간염 바이러스의 표면항원 및 프리에스 항원을 암호화하는 유전자가 소아마비 바이러스유전자에 삽입되어져야 하나, 이와 같은 대량의 외래성 유전자의 삽입은 소아마비 바이러스의 생존능력을 상실하게 하므로, 대량의 외래성 유전자를 삽입시키면서도 증식능력을 유지시킬 수 있도록 하기 위하여 결손형 방해(DI) 바이러스와 조력자 바이러스(Helper virus)가 공존하는 형태로 백신을 제조하였다. 
     일반적으로 DI 바이러스는 공시 바이러스(standard virus)의 유전자에 결손(본 발명에서는 이 결손부위에 B형 간염 바이러스 표면항원 및 프리에스 항원을 암호화하는 유전자를 삽입)이 있는 돌연변이로서, 조력자 바이러스의 공존하에서만 증식이 가능하며 시간이 지남에 따라 그 증식비율이 공시 바이러스의 증식비율보다 커지는 현상 즉 인리취먼트(Enrichment)현상을 나타내게 된다. 
     본 발명에서는 이상과 같은 원리를 이용하여 소아마비 바이러스의 외피 단백질을 암호화하는 부위에 B형 간염 바이러스의 표면항원 및 프리에스 항원을 암호화하는 유전자를 삽입시켜 재조합 DI 바이러스 벡터를 만들고, 벡터 자체 또는 시험관내 전사(In vitro transcription)에 의하여 만들어진 재조합 DI 바이러스의 RNA 트랜스크립트를 영장류 동물세포에 트랜스팩션 시킨 다음 조력자 바이러스로 슈퍼인펙션 시키고 인리취먼트 될 수 있도록 바이러스를 계대배양하여 경구용 B형 간염백신을 제조하였다.

Title: Improved sprayable portland cement-based fireproofing compositions
Inventor: PERITO P RICHARD P
IPC: C04B28/14
Filed: 1993-04-15
Granted: 2000-01-15
Abstract: Sprayable fireproofing compositions for structural members such as steel columns are provided, as well as a method of applying multiple coatings thereof. The compositions comprise a Portland cement-based material, stucco, and an accelerator. The compositions eliminate the long setting times typical of Portland cement-based materials, and improve the hangability thereof. The product is produced by dry blending a mixture of Portland cement, stucco (calcium sulfate hemi-hydrate) and optionally, a stucco set retarder and shredded polystyrene aggregate. Upon the addition of water, sprayable slurries are formed which can be pumped to the point of application. An accelerator is added in close proximity to the point of injection. Other additives may also be included, such as starch, adhesives and cement strength enhancers. The slurries adhere to the structural member in the slurried state and after setting to provide excellent fire and heat protection. Because of the relative quick setting time of the slurry upon spray application, multiple coatings can be applied within the same working day.

Title: Impurity doping method with diffusion source of boron-silicide film
Inventor: AKAMINE TADAO
IPC: H01L21/225

Granted: 2001-11-22
Abstract: PURPOSE: A solid phase diffusion process is provided to improve controllability of diffusion of boron impurity into a silicon substrate and to achieve a shallow junction by using a boron silicide film as diffusion source. CONSTITUTION: A process includes: cleaning the surface of a Si substrate(1) by removing a native oxide film thereof to expose an active surface; treating the active surface to form thereon a boron silicide film(2) as an impurity source; and introducing boron impurity from the boron silicide film into the Si substrate to form a boron diffusion layer(3). The boron diffusion layer(3) having a high surface concentration and a shallow junction is formed because the boron silicide film(2) is formed directly on the surface of the Si substrate(1). Because the boron silicide film(2) is chemically and physically stable, an improved diffusion controllability is obtained.

Title: Method of processing smpte signal
Inventor: HA TAE JONG
IPC: H04N5/60
Filed: 1993-11-03
Granted: 2001-05-02
Abstract: PURPOSE: A method of processing an SMPTE signal is provided to effectively process SMPTE signals using a gate and a micro-controller existing in a MIDI interface card without employing a dedicated IC. CONSTITUTION: A system for recognizing and mixing SMPTE signals is initialized. It is checked if the current state is SMPTE receive state or SMPTE send state. One of a receive routine, a send routine and a decode routine is called according to the states. When the receive routine is called, the receive routine checks time interval between the previous interrupt and current interrupt using an input SMPTE signal as an interrupt source when an interrupt generates, and decodes the time interval into a one-bit or two-bit SMPTE signal.

Granted: 1997-06-30
Abstract: A bilateral charged coupled device capable of changing a transmission direction right or left according to an external control signal is disclosed. In the bilateral charged coupled device, an N area(2) and an M area(3) of a low density are formed at a selecting area by turns. A gate oxide film(4) is formed on N area(2) and M area(3) of a low density. First and second gates(5,6) is formed on gate oxide film(4) in such a way that first and second gates(5,6) correspond to N area(2) and M area(3) of a low density, respectively. Each drain of a plurality of transistors(T1,...,Tn) are connected to first and second gates(5,6). At least one inverter(7) is connected to a charge transmission direction control signal line.   1 and    12 phase signal lines(L1,L2) are connected to odd and even numbers electrodes of first gate(5), respectively.

Abstract: 본 발명은 에칭의 이방성의 정도에 관한 피처리기판의 면내균일성을 향상시키고, 이방성 에칭에 의해 형성되는 피에칭측면을 직각으로 접근시키기 위한 것으로, 평행평판형의 플라스마 에칭장치는 처리실(1)내에 배치된 서셉터전극과 샤워전극을 구비하며, 서셉터전극상에  반도체 웨이퍼가 설치되고, 샤워전극에는 복수의 처리가스공급구멍에 의해 규정되는 샤워영역(SR)이 형성된다.  샤워전극은 냉각블록에 의해 냉각되고, 이에 의해 샤워전극의 유효전극부는 그 주변이 그 중심보다 온도가 낮은 온도균배를 갖는다.  사워영역(SR)의 직경은 웨이퍼의 직경보다 5~25% 작고, 유효전극부의 온도균배에 기인하여 발생하는 에칭의 이방성의 정도에 관한 웨이퍼의 면내균일성의 저하를 보상하도록 선택된다.  또, 유효전극부의 직경은 웨이퍼(W)의 치수보다도 5~35% 크고, 에칭에 의해 형성되는 피에칭측벽의 테이퍼각이 85도~90도가 되도록 선택된다.
