Title: Arrangement for automatic switching of the regulating speed of a phase regulating circuit
Inventor: DIETERLE FRANZ
IPC: H03L7/10
Filed: 1988-05-13
Granted: 1995-05-17
Abstract: An arrangement for automatic switching of the regulating speed of a phase regulating circuit, in which the regulating speed is not switched abruptly. The regulating speed is, instead, switched either discontinuously or continuously, so that it does not attain a high level before the midpoint of the synchronizing pulse. The regulating speed is increased within a synchronizing window to an increasing extent up to the midpoint of the window, whereas the regulating speed decreases to a decreasing extent from that midpoint. The regulating speed of the phase regulating circuit is associated with the horizontal deflection in a television receiver, where interference in the vicinity of the synchronizing pulse has a detrimental effect, particularly near the edges.

Abstract: B형 간염 백신을 경구용으로 개발하기 위하여 소장 점막을 통한 침입 경로를 가지는 소아마비 바이러스를 운반체로 사용하였다. 약독화된 소아마비 바이러스는 현재 경구용으로 사용되고 있는 매우 안전한 바이러스이다. 
     B형 간염 바이러스에 대한 면역성을 유발시키기 위해서는 B형 간염 바이러스 표면 항원을 암호화 하는 유전자가 소아마비 바이러스의 유전자에 삽입되어져야하나, 다량의 외래성 유전자룰 삽입할 경우 소아마비 바이러스의 증식 능력을 상실하게 되므로 소아마비 바이러스의 증식에 영향을 미치지 않는 범위내에서 B형 간염 바이러스 표면 항원을 암호화하는 유전자 일부와 치환해야 한다. 
     본 발명에서는 이상의 원리를 이용하여 B형 간염 바이러스의 표면 항원 중 가장 우수한 면역원성을 지니는 항원 결정부위롤 암호화하는 유전자를 합성한 후이를 소아마비 바이러스 유전자 부위중 항원 결정 부위와 치환시켜 재조합 간염-소아마비 바이러스 벡터를 만들고 이를 영장류세포에 트랜스 팻션(transfection)시켜 재조합 바이러스를 만들었으며, 증식된 재조합 바이러스를 대량 배양하여 경구용 B형 간염 백신을 제조하였다.

Title: Voltage up inhibition circuit and output buffer circuit with it
Inventor: YU JE-HWAN
IPC: H03K5/007
Filed: 1992-02-14
Granted: 1994-06-20
Abstract: The boost limiter circuit (20) settles the high output voltage of logic circuits into a specific low voltage and the output buffer circuit with the boost limiter represents fast response speed and low ground noise. The boost limiter circuit consists of a resistor (Rs) which is made up of polysilicon or p+ area or n+ area of semiconductor substrate, and a capacitor (Cs) which is made up of CMOS structure. The circuit is placed between boost circuit (10) and ground. The output buffer circuit consists of the boost circuit, the boost limiter circuit, and a pair of CMOS transitors (M1)(M2) for pull-up and pull-down of output signal.

Abstract: 음성 신호의 A-D 변환시에, 상위 비트의 데이타에 의한 하위 비트의 데이타의 이동을 약화하여, 재생 음성의 청감상의 품위를 향상시킨다. 
     아나로그 음성 신호 SA를 주파수 N·fs를 오버샘플링해서, 짧은 워드장의 데이타를 생성하는 프론트엔드(10)와, 상기 프론트엔드 출력의 데이타 레이트를 소요 샘플링 주파수 fs까지 인하 하여, 긴 워드장의 출력 데이타로 변환하는 1쌍의 데시메타(2A, 2B)를 설치하고, 한 방향의 데시메타(2A)에는 프론트엔드의 출력을 공급함과 더불어, 다른쪽의 데시메타(2B)에는 프론트엔드의 출력을 비트시프트 다운해서 공급하고, 양 데시메타의 출력을 가산한다.
