Title: Suprorted vanadium catalyst for polymerization of olefins and a process of preparing and using the same
Inventor: CHANG MAIN
IPC: C08F4/68
Filed: 1989-11-07
Granted: 1998-07-15
Abstract: This invention relates to a supported vanadium-alumoxane catalyst for use in gas and liquid polymerization of olefins. The invention particularly relates to the use of silica gel containing from about 6 to about 20 percent by weight adsorbed water as the catalyst support material. The particle size of the silica gel is generally between about 0.1 and 200.0 mu  Such silica gel may be safely added to a trialkylaluminum solution to form by direct reaction with the adsorbed water content of the silica gel catalyst support material the alumoxane cocatalyst component of the catalyst system. An alumoxane coated silica gel is formed to which a vanadium compound is added and the resulting material dried to a free flowing powder. The dry free flowing powder may then be used as a supported vanadium alumoxane catalyst complex for the polymerization of olefins. Resins produced from such processes have a broad molecular weight distribution suitable in blow molding for the fabrication of household and industrial containers.

Abstract: 본 발명은 전화라인과 연결되는 팩시밀리에서 상기 전화라인으로부터 과전압이 유입될시 이를 방전시켜 팩시밀리를 과전압으로 부터 보호할 수 있는 기능을 제공한다. 이를 위하여 전화회로의 양단 간에 제과전압제어수단을 연결하여 전화라인으로 유입되는 과전압을 방전한다. 이때 1차 방전된 신호가 과전압 상태로 발생되면 제1과전압제어수단과 연결되어 송수신되는 신호를 매칭시키는 트랜스수단을 통해 팩시밀리와 전화기를 선택하는 릴레이수단으로 인가되어 릴레이들을 손상시킨다. 이를 방지하기 위하여 트랜스와 연결되는 제2방전제어수단을 구비하여 제1과전압제어수단을 통해 수신되는 신호가 과전압 레벨일 시 상기 전화라인과 팩시밀리를 순간적으로 분리시킨다.

Abstract: 본 발명은 공구직경 이동경로 보정시작점과 종료점의 각도(θ)가 0  θ  90。인 경우 공구이동 경로를 보정생성할 수 있는 공구경에 따른 이동경로 보정 방법에 관한 것으로써, 공구직경에 따른 이동경로 보정방법은 공구직경에 따라 보정된 이동경로를 움직이는 CNC공작기계에 있어서, 공구이동방향의 좌우측 또는 보정무시해도 좋을 것인지의 여부를 판단토록 해당코드를 읽어 들이는 제1단계와, 공구직경에 따른 이동경로보정 시작점과 종료점간의 벡터d1을 구하는 제2단계와, 상기 제2단계에서 구해진 d1벡터값을 X-Y평면과 수직인 Z축을 중심으로 반시계방향으로 90。회전시킨 n1벡터를 구하고, 보정종료점에서 Z축을 중심으로 반시계방향으로 상기 n1벡터와 평행이동되는 n1'벡터를 구하는 제3단계와, 상기 제2단계 및 제3단계에서 구해진 두 벡터d1,n1'합성성분인 n2벡터를 구하는 제4단계와, 보정종료점에서 다음 블록간의 d2벡터를 구하는 제5단계와, 상기 d2벡터에 수직한 n3벡터를 구하는 제6단계와, 상기 d2벡터와 크기는 같으나 방향이 반대인 d2'벡터를 구하는 제7단계와, 상기 n3벡터와 d2'벡터 합인 n4벡터를 구하는 제8단계와, 상기 n1', n2, n3, n4벡터값을 램을 통해서 제2마이크로프로세서에 입력하여 제어명령 신호를 발생토록하고, 이 제어명령신호를 D/A변환기에 의해 아날로그 신호로 변환한 후 써보모터에 인가하여 공구직경에 따라 보정된 이동경로를 공구가 움직이도록 하는 제9단계로 이루어진 것을 특징으로 한다.

Title: 용융 금속 용기의 슬라이딩 게이트 밸브용 밸브판 조립체
IPC: B22D11/10
Filed: 1992-10-20
Granted: 2000-03-02
Abstract: 용융 금속 용기(10)의 슬라이딩 게이트 밸브용 밸브판 조립체(22)의 상부 밸브판(31)은 슬라이딩 표면(22′)의 반대측 표면에 용융 금속 배출공(25)보다 넓은 홈(31′)을 갖고 있고 홈(31′)에 내화 삽입체(30)가 삽입 고정되었으며, 삽입체(30)와 상부 밸브판(31) 사이에는 가스 통로(32)가 형성되었음. 가스 통로(32)는 삽입체(30)와 홈(31′) 저면 사이의 간극으로 구성됨. 가스는 밸브 폐쇄시 가스 통로(32)를 통하여 용융 금속 배출공(25) 속으로 주입되어 용융 금속의 응고를 방지함. 밸브판(22)은 구조가 간단하고 제작이 간편하며, 삽입체(30)는 슬라이딩 밸브판과 직접 접촉하지 않게 되어 있어서 삽입체(30)와 밸브판(22)의 수명이 연장됨.

Title: Reduced color image scanner
Inventor: KIM NAM RYOUNG
IPC: H04N1/024
Filed: 1992-10-30
Granted: 2000-10-16
Abstract: PURPOSE: A lens reduction type color image scanner is provided to reduce a manufacturing cost by decreasing the number of device for processing an analog video signal. CONSTITUTION: A timing control portion provides one or more clock control signal to each color CCD(Charge Coupled Device) image sensor. Each color CCD image sensor is controlled by the provided clock control signal. A sensor amplification portion amplifies output signals of each color CCD image sensor. A multiplexing portion multiplexes a signal outputted from the sensor amplification portion and transfers the multiplexed signal to an ADC.
