Title: Apparatus for optically scanning information plane
Inventor: BRESSERS ANDREAS JOHANNES MARI
IPC: G11B7/08
Filed: 1988-07-21
Granted: 1997-04-22
Abstract: An apparatus is described for scanning an optical record carrier (1) in which a radiation beam (b) emitted by a source (4) is focussed by a lens system (6) and in which radiation reflected by the record carrier is focussed in two radiation spots (V1, V2) each co-operating with a separate detector pair (18, 19; 20, 21). Acombined beam-separating and beam-splitting element is constituted by a diffraction grating (9) comprising two sub-gratings (12, 13) with different grating parameters. The sub-gratings have varying grating periods (p1, p2) and curved grating strips (14, 15) so that less stringent requirements are imposed on the mutual positions of the source (4) and the detectors (18, 19; 20, 21).

Abstract: 본 발명은 전원전압을 검출하여 매 순간마다 순시위상을 연산하는 제어에 관한 것으로, 일반적으로 사용되고 있는 순시 위상 제어회로는 제로 크로싱 검출부를 채용하고 있는데, 정상적인 전원전압이 아닌 외부 노이즈 입력시에 제로 크로싱 기능에 의해 위상이 잘못 계산될 수 있으며, 사용된 업 카운터의 값이 정수화된 값일 경우에는 제로 크로싱하는 부분에서 불연속 파형이 생기게 되는 문제점이 있게 된다. 
     이에 따라서 본 발명은 상기와 같은 종래의 순시위상 제어회로에 따르는 결함을 해결하기 위하여, 외부 노이즈 입력시의 위상 오연산을 방지하고 상회전 방향이 잘못 입력되었을 경우에도 제어회로가 동작될 수 있게 하며, 전원전압을 검출하여 순시위상을 연산할 수 있게 하는 순시위상 제어회로를 제공하는데 그 목적이 있다.

Abstract: 본 발명인 속도제어 방법 및 장치는 실제속도의 성분 중에서 직류성분을 소거하는 과정과, 실제속도의 교류성분에 지령속도의 직류성분을 첨가하는 과정과, 지령속도전압에 미소전압을 가산하는 과정과, 지령속도전압에 미소전압을 감산하는 과정과, 실제속도의 교류성분에 지령속도의 직류성분을 첨가한 신호와 지령속도전압에 미소전압을 가산한 신호를 비교하는 과정과, 실제속도의 교류성분에 지령속도의 직류성분을 첨가한 신호와 지령속도전압에 미소전압을 감산한 신호를 비교하는 과정과, 비교과정의 결과들에 의해서 실제속도를 속도오차 발생의 입력으로 사용할 것인지 아니면 지령속도로 대치할 것인지를 결정하는 과정을 포함하고, 이러한 방법을 실현하기 위한 장치를 구비한 것을 특징으로 한다. 따라서, 속도제어 분야에서 속도제어시 실제속도와 지령속도와의 차이가 일정한 범위(ΔV)보다 더 크거나 더 작을 경우에 실제속도 측정오류로 보고 실제속도를 지령속도로 대치시켜 주어서 제어계의 신뢰성을 높여주는데 있어서 효과적인 발명이다.

Abstract: 본 발명은 잉크제트 프린트 카트리지용의 신규한 노즐부재와, 그러한 노즐부재의 제조방법에 관한 것이다. 이러한 방법에 있어서, 노즐 또는 오리피스는 엑시머레이저 융제에 의해 가요성 중합체 테이프내에 형성된다. 일 실시예에 있어서 가열요소를 수용하는 기재는 노즐부재의 배면상에 장착된다. 기재에 전기신호를 제공하기 위한 도선은 가요성 중합체 테이프의 내측에 배치되며, 기재상의 관련전극위에 배치된 비아에서 종지된다. 
     비아는 도선을 관련 전극과 전기 접속시킨다.
