Title: Sequence interlace method of television for high accurate picture
Inventor: JUNG MIN-HYONG
IPC: H04N3/12
Filed: 1985-10-25
Granted: 1989-10-27
Abstract: The scanning icrcuit converts the interlace video signal into the non-interlace signals having double horizontal scanning frequency for high quality television set.  The data buffers (1-4) operated under the control signals (EN1-EN4) temporarily store digital video signals converted by the A/D converter (17) receiving the interlace video signals and transfer the data to the field memories (5 to 8) which are sequentially read to the output buffers (12-15).  The data stored in the output buffers operated under the control signal (EN5 to EN8) having double frequency compared to the control signals (EN1-EN4) are converted again into analog signals for a non-interlace high quality television set.

Abstract: 본 발명은, 도시 쓰레기에서 알루미늄 쓰레기를 분리 회수하기 위해서 가장 적합한 비자성 금속 분리 벨트 컨베이어에 관한 것이다. 
     종래, 구동 롤러와 통체와의 사이에 벨트를 배치하고, 그 통체의 내부에 이 통체의 회전속도보다 빠른 회전제어를 받는 영구 자석체로서 되는 장치가 채용되고 있으나, 알루미늄 및 쓰레기 회수 후, 자성재만이 통체로부터 떨어질때까지 이행한다. 
     이때, 원형외주를 갖는 워셔등은 자전에 의해 통체에서 분리하지 않는 상태가 계속되어 후속하는 쇠 부스러기의 배출을 방해할 뿐만 아니라 날카로운 모서리를 가지는 워셔의 경우, 벨트가 찢어지는 일이 있었다. 
     그래서, 본 발병에서는 쇠 부스러기와 쓰레기를 함께 회수하는 구성으로 하고 있다. 
     본 발명의 벨트 컨베이어에 의하면, 통체로 부터 분리되는 곳에서 자성체가 자전하더라도, 자전방향은 후속의 쓰레기를 잡아서 들어가는 방향이기 때문에 곧바로 쓰레기와 함께 통체로 부터 떨어져서 이 통체의 손상을 방지할 수 있다.

Abstract: 본원 발명에 의한 일 발생 혼합 시스템은 고압가스저장탱크와, 터빈과, 압축기와, 저압저장탱크와, 열교환기와, 밸브 등의 유량제어 기구로 구성되어 있다. 고압저장탱크는 주위 공기와 열교환 관계에 있으며, 유체를 주위 온도에서 터빈으로 이송한다. 터빈으로부터 사용된 유체가 배기되어 압축기와 열교환 관계로 유도된다. 압축기의 배출온도는 터빈배기온도보다 높다. 압축기에 의해 가열된 배기유체는 주위 공기와 열교환 관계에 있는 저압저장탱크로 이송되고, 여기에서 압축기에 의해 가열된 배기유체는 압축기 입구로 이송된다.

Abstract: 본 발명의 바닥용 매트는 상부면층과 기부층을 갖는 유연성의 다층구조물로 되어 있다. 기부층은 변부로 둘러싸인 주동체부를 갖는다. 주동체부는 비교적 얇고 변부는 비교적 두껍다. 기부층의 표면은 매트가 깔리는 바닥면의 형태에 적응할 수 있게 되어 있다. 변부에는 그 길이방향으로 연장되고 이 변부의 저면으로부터 하측으로 개방된 채널이 형성되어 있다. 주동체부의 일부에도 채널이 형성되어 주동체부의 일부가 주동체부의 나머지부분의 상부에 배치되므로서 주동체부에 장식부를 구성한다.
