Title: Selective amplification of target polynucleotide sequences
Inventor: BURG LAWRENCE JAMES
IPC: C12Q1/68
Filed: 1989-03-30
Granted: 1996-10-09
Abstract: A method is provided for multiplying the number of copies of a target polynucleotide sequence comprising a series of primer hybridization, extending, and denaturing steps to provide an intermediate double-stranded DNA molecule containing a promoter sequence (through the use of a promoter-sequence-containing primer) incorporated upstream from the target sequence. The double-stranded DNA intermediate is then used to grow multiple RNA copies of the target sequence. The resulting RNA copies can be used as target sequences to produce further copies. Multiple cycles of this sort can thereby exponentially increase the number of target sequence copies.

Abstract: 정전 고전위가 유지되는 출력 단자를 갖는 정전 고전위 공급원과, 코팅 물질 공급원 및, 코팅 물질 분배용 분배 장치로 이루어지는 코팅 물질 분배 시스템에 관한 것이다. 상기 출력단자는 분배 장치에 의해 분배된 코팅 물질에 전위를 제공하기 위해 연결된다. 상기 분배 장치는 단자로부터 코팅물질 공급원으로의 코팅 물질을 통과하는 전기적 경로를 막는 전압 블록에 의해, 그리고 지면에 연결되고 보호를 위해 내마모성 물질 로그 주위가 둘러싸이는 전기적으로 비절연성의 수지 차폐층이 그 주위에 제공된 전기적으로 비전도성의 도관을 구비하는 긴 튜브에 의해 코팅 물질 공급원에 연결된다. 상기 긴 튜브는 전압 블록과 분배 장치 사이에 연결된다.

Abstract: 본원 발명은 반도체장치의 제조분야 등에 있어서 적용되는 드라이에칭방법, 특히 실리콘트렌치에칭 등의 고애스펙트비가공을 양호한 이방성을 가지고 고속으로 행하는 방법에 관한 것이다. 본원 발명은 S 2 Cl 2 에 S 2 Cl 2 를 첨가하여 이루어지는 에칭가스를 사용하여 실리콘기판을 0℃ 이하로 냉각한 상태에서 트렌치에칭을 행한다. 에칭반응은 Cl + 등의 이온에 의한 이온어시스트반응을 주체로 하여 이방적으로 진행하나, 반응계내에 약간 양 존재하는 F * 에 의해 라디칼반응도 진행하고, 고속에칭이 가능하게 된다. 한편, 상기 가스의 방전 해리에 의해 플라즈마내에 생성한 S는 냉각된 웨이퍼의 표면중 패턴측벽부에 퇴적하고, 이방성의 향상에 기여한다. 더욱이, 퇴적한 S는 웨이퍼의 승온 또는 산소플라즈마처리에 의해 용이하게 제거 가능하므로 파티클오염을 야기할 염려가 없으며, 실리콘트렌치에칭에 있어서 고이방성, 고속성, 저오염성을 동시에 달성한다.

Abstract: 본 발명은 터보 머신용 블레이드 동기 진동을 감시하는 시스템 및 방법을 제공한다. 각각의 블레이드의 도달을 검출하는 적어도 3개의 센서는 블레이드 팁을 둘러싸는 원주상에 배열된다. 센서의 위치는 데이터의 에러 영향을 최소화하도록 선택된다. 이를 달성하고 센서를 실린더에 간단히 설치하기 위해, 센서간의 간격은 균일하지 않을 수 있다. 푸리에 변환을 구성하기 위해 각각의 센서 위치는 로터 회전비로서 표현되는 각 센서에 대한 블레이드의 도달 시간을 이용함으로써 결정된다. 변환 행렬은 M개의 고조파가 동시에 분석되도록 사전설정된 M개의 고조파 이산 세트에 대하여 구성된다. 동시에 분석될 수 있는 고조파 수는 사용되는 센서의 수에 관련된다. 로터 회전비로 표현되는 각 센서의 블레이드 도달 시간 데이터는 세트에 대해 선택되는 각 고조파의 블레이드 진동의 진폭을 결정하기 위해 분석된다. 초기 세트에 포함되지 않은 고조파의 현저한 진동이 존재할 때 야기되는 결과를 정확하게 분석하기 위해 계산은 여러 고조파 세트에 대하여 반복적으로 수행된다.

Abstract: 동일 상품의 수납고내에 냉각 장치와 가열 장치가 병설된 자동 판매기에 있어서 온도 검출 소자의 수를 줄인다. 온도 검출부(1)에는 냉각 운전과 가열 운전인 양쪽의 운전 모드에 겸용인 1개의 온도 검출 소자를 두고, 냉각·가열 절환 스위치(6)에서의 입력 신호에 따라서 기억부(4)에서 선택적으로 읽어낸 냉각 설정 온도 또는 가열 설정 온도와 이 온도 검출 소자의 출력을 비교부(5)에서 비교하는 냉각 장치(7) 또는 가열 장치(8)를 온 오프 제어하도록 한다. 냉각운전과 가열 운전에 각각 전용의 온도 검출 소자를 둔 종래 구성에 비해서 소자의 수가 적어진다.
