Title: Record carrier scanning apparatus with feedback control system for controlling scanning point position and velocity
Inventor: BIERHOFF MARTINUS P M
IPC: G11B21/10
Filed: 1989-10-04
Granted: 1999-04-15
Abstract: A device is disclosed for scanning a record carrier (1) provided with substantially parallel tracks, which device comprises a closed-loop position control system with position and velocity feedback for controlling the scanning point (P) towards the centre of a specific track. For this purpose the position control system comprises a positioning system (15) for moving the scanning point in a direction transverse to the tracks, a measuring system (4, 6, 9, 10, 11, 12, 13) for generating a velocity signal (RS) which is indicative of the velocity with which the scanning point (P) is moved across the tracks, and for generating a first error signal (RE) whose magnitude, within a predetermined limited range to either side of said specific track, is proportional to the deviation between track centre and the scanning point (P). The position control system further comprises a control circuit (3) for controlling the positioning system depending on the first error signal (RE) and the velocity signal (RS). The control circuit (3) comprises means for generating at least one substitute error signal (PE min , UC min ) which within a second range, outside the first range, has a sign which is indicative of the direction of the deviation, the control circuit (3) being adapted to control the positioning system (15) in response to the first error signal (RE) or a substitute error signal (UC min , PE min ) depending on whether the deviation is situated in the first range or the second range respectively, in such a way that the error signal employed for position feedback depends on the magnitude of the deviation, and the velocity signal (RS) used for velocity feedback is independent of the magnitude of the deviation.

Abstract: 저잡음 주파수 합성장치(10)는 주파수 분주기(13,15) 및 위상/주파수 검출기(17)의 아날로그 이득보상을 사용하여 통상의 주파수 합성방법보다 낮은 잡음, 낮은 기생레벨 및 빠른 스위칭 속도를 제공하는데, 상기 두 분주기(13,15)중 적어도 하나(분주기(15))는 반정수 단계에서 증분 및 감분가능하다.  본 발명의 핵심적 특성은 반정수 분주기(13,15)들 및 위상 제어기 이득을 조절함으로써 분주수 변화에 대해 루프를 보상하는 능력이다.  주파수 합성장치(10)는 두개의 분주기(13,15)를 구비하는데, 이들은 주파수 합성장치(10)의 입력 신호 및 출력신호로 작용하는 두개의 기준 주파수 신호를 제공한다.  전압 제어 발진기(VCO)(18)는 주파수 합성장치(10)의 출력신호(f O )를 제공한다.  위상/주파수 검출기(17)는 상기 기준 주파수 신호들을 비교하여 VCO(18)로 전달되는 위상 에러 출력신호를 제공한다.  PROM(11) 및 디지탈 아날로그 변환기(12)를 구비하는 디지탈 제어기는 위상 검출기(17)의 이득을 조절함으로써 분주수 변화를 보상하여 분주수를 선택한다.  주파수 합성장치(10)는 낮은 위상 잡음, 낮은 기생레벨 및 빠른 채널 스위칭을 제공한다.  주어진 크기의 주파수 단계를 발생하기 위해서 분주수는 그 단계 크기의 절반이다.  단계크기의 절반의 분주수를 가짐으로서 분주기로부터의 잡음분포는 그만큼 감소된다.  위상마진은 잡음 스펙트럼에서의 루프 피킹의 감소에 따라 개선된다.  본 발명의 주파수 합성장치를 사용하는 미사일 레이다 시스템이 또한 개시된다.

Granted: 2001-10-24
Abstract: PURPOSE: A method for fabricating a structure useful in semiconductor circuitry is provided to obtain a high-dielectric constant oxide by using a Ge buffer layer. CONSTITUTION: A method comprises: growing a germanium layer(28) directly or indirectly on a semiconductor substrate(20); and depositing a high-dielectric constant oxide(32) on the germanium layer. Preferably, the germanium layer(28) is epitaxially grown on the semiconductor substrate. A second germanium layer(40) is grown on top of the high-dielectric constant oxide(32) and a conducting layer(42) is grown on the second germanium layer. Preferably, the high-dielectric constant oxide is a titanate, such as barium strontium titanate.

Title: Rotary typed diffuser adjustable as to airflow
Inventor: JUNG SI-YOUNG
IPC: F24F13/062
Filed: 1993-05-24
Granted: 1996-03-28
Abstract: The apparatus forms coaxially a hollow cylinder outside a simple air diffuser, and regulates the air flow discharged from a passageway formed on between the two cylinders so that it can enhance cooling efficiency. The apparatus comprises the inner cylinder(5) having the revolving blades(7) for forming a revolving air flow; the outer cylinder(8), coaxially fromed outside the inner cylinder(5), forming a non-revolving air diffusing passageway(9); and an air flow regulator(10), movable up and down with a screw, installed on the lower part of the inner cylinder(5).
