CONSTITUTION: The fusion protein of epitope in envelope protein of hepatitis C virus is manufactured by the next steps of: i) amplifying epitope genes in envelope protein of hepatitis C virus through PCR and purifying amplified DNA segments to obtain DNA segment, E1D2; ii) making an expression vector for E. coli; iii) transforming E. coli W3110 (ATCC 37339) to manufacture recombinant E. coli having ptrpH-UB-E1E2 inserted with DNA segment E1E2; iv) cultivating the strain in broth and centrifuging it for 25 minutes at 11,000rpm to obtain cell sediments; and v) measuring the expression of protein UBE1E2 and reacting the protein with serum of hepatitis C patients.

Abstract: 디지탈 위상 고정 루프는 소정의 주파수를 갖는 제 2 신호에 제 1 신호를 동기화시킨다. 제 1 신호는 대개 소정의 주파수보다 더 큰 순간 주파수를 가지고 있기 때문에 제 2 신호에 대해 위상을 일정하게 얻는다. 디지탈 위상 고정 루프는 제 1 신호와 제 2 신호간의 소정의 위상 관계를 주기적으로 검출하여 소정의 위상 관계가 검출될 때 제 1 신호의 위상을 소정의 양만큼 확장시킴으로써 주기적인 보정 사이클을 실행한다. 바람직하게도, 제 1 신호는 클록 주파수를 가지고 주파수 분할기를 클록시킴으로써 발생되고, 또한 각 보정 사이클에 대한 1 클록 사이클동안 주파수 분할기의 클록을 금지시킴으로써 확장된다. 바람직하게도, 제 2 신호가 클록 신호에 의한 클록과 일치하는 소정의 논리 상태와 주파수 분할기의 소정의 상태를 가질때 소정의 위상 관계가 검출된다. 디지탈 위상 고정 루프는 데이타 프로세서 클록 주파수의 약수에서 각 프로세서의 디지탈 위상 고정 루프에서의 주파수 분할기의 초기 스테이지로부터 각 데이다 프로세서 클록을 취함으로써 데이타 프로세서 클록을 기준 클록에 동기화시키도록 데이터 프로세서 시스템에 사용될 수 있다.

Title: 텔레비젼 화면의 종횡비 변환장치

Abstract: 본 발명은 텔레비젼 수상기의 화면 종횡비 변환장치(ARC; Aspect Ratio Convertor)에 관한 것으로서, 특히 수직 방향으로 화면을 확장할때 나타나는 화질 저하 현상을 방지할 수 있도록 한 텔레비젼 화면의 종횡비 변환장치에 관한 것이다. 
     종래의 텔레비젼 화면의 종횡비 변환장치에서는 제 2 도의 (b),(c)에 도시된 바와같이 V3라인과 V5라인 사이에 수직 방향으로 영상신호의 천이가 발생할때 V5라인이 0 IRE 레벨로 입력되어도 확장된 CV5라인에서는 50 IRE, CV7 라인에서는 25 IRE의 출력이 나타나게 되어 화질이 저하되고 수직 해상도가 저하되는 문제점이 있다. 
     본 발명은 입력 영상신호를 미디언(MIDEAN)처리를 통해 수직 천이영역에 대한 보상을 선행한 후 선형 연산을 수행하여 수직 방향으로 영상신호라인을 확장하므로서 천이영역에서의 신호 손상을 억제하고, 이에 따른 화질 향상과 고선명 영상의 표현을 기 할 수 있도록 한 텔레비젼 화면의 종횡비 변환장치 이다.
