Title: 동적 스월필터 조립체 및 이를 이용한 여과 방법
IPC: B01D29/39
Filed: 1996-10-09
Abstract: 동적 스월필터 조립체는 여과력을 향상시키기 위하여 필터의 표면에서 유체 전단층을 주기 위한 회전가능 필터 하우징을 갖는다. 동적 스월필터 조립체는 회전가능 필터 하우징을 이용하여, 복수의 고정 디스크형의 필터 요소의 표면에 바로 인접한 곳에 유체 전단 경계층을 부여한다. 유체 전단 경계층은 소정 크기의 입자 및/또는 콜로이드 물질을 상승시켜 이들이 필터 요소의 표면에 붙는 것을 방지한다.

Title: 디지탈기록방법,디지탈디스크,디지탈디스크기록장치및디지탈디스크재생장치
IPC: G11B20/14
Filed: 1997-07-28
Abstract: 디지탈 디스크(10)에는 클럭 신호를 재생하기 위해서 워블링시킨 워블 신호로 사행한 그루브가 형성되어 있다.  광 헤드(26)에 의해 워블 신호가 판독되고, 어드레스 검출 회로(40)는 워블 신호에 다중되어 있는 어드레스 신호를 검출하고, PLL 발진 회로(24)는 워블 신호에 동기한 클럭 신호를 출력하고, 이 클럭 신호와 어드레스 신호에 기초한 타이밍 신호에 기초하여 데이타가 변조 회로(16)에 의해 변조되고, 디지탈 디스크(10)에 기록된다.  재생시에는, 워블 신호에 포함되는 RF 신호를 A/D 변환기(42)에 의해서 디지탈 신호로 변환하고, 복조 회로(44)에 의해서 복조하여 데이타를 출력한다.

Title: 자동차용 레이더 센서
IPC: G01S7/02
Filed: 1997-01-09
Abstract: 적어도 하나의 송신-안테나 부재(3)와 적어도 하나의 수신-안테나 부재(41, 42, 43)들에서부터 하나의 공통 발진기(5)로 연결하는 연결도선의 길이를 가능한 한 짧게 구현할 수 있도록, 상기 수신-안테나 부재(41, 42, 43)들을 상기 송신-안테나 부재(3)의 방사선 다이어그램(7) 외측에 설치한다. 여기서 상기 송신-안테나 부재(3)와 수신-안테나 부재(41, 42, 43)들은 서로 다른 방향을 향하도록 한다. 상기 반사된 레이더선(9)을 수신-안테나 부재(41, 42, 43)에 우회시키며, 및/또는 상기 송신-안테나 부재(3)에서 출력된 레이더선(7)을 원하는 방향으로 우회시키는 수단(10)이 구비되어 있다.
