Patent KR-20000068346-A (KR)
IPC: B21B1/46
Filed: 1997-07-24
Abstract: In the production of grain oriented electrical steel sheet, controlling the condition of thin slab continuous casting results in advantageous solidification structures and precipitates. The steel has an initial content of carbon less than 300 ppm and an initial content of acid-soluble aluminum higher than that normally used for said type of steel. During the final processing steps, the annealed sheet is nitrided through a limited amount of nitrogen. This, in turn, renders the process for controlling the grain dimensions much less critical and results in a constant quality product.

Abstract: 무선 통신 시스템은 패킷 데이터 네트워크에서 네트워크 장치로 데이터 세션을 설정하기 위해서 무선 유니트와 기지국 간의 회로 스위칭 링크를 이용한다. 데이터 세션이 설정된 후에, 데이터 세션은 무선 유니트와 기지국 간의 회로 스위칭 링크를 계속해서 이용할 수 있다. 데이터 세션 셋업 패킷들을 전송하기 위해 회로 스위칭 링크를 이용함으로써, 시스템은 패킷 스위칭 링크를 이용하여 셋업 패킷을 전송할 시 무선 자원 요청 및 할당과 관련있는 지연을 피한다. 데이터 세션 셋업과 관련있는 지연을 감소시킴으로써, 무선 통신 시스템과 패킷 데이터 네트워크 간의 데이터 속도 및 쓰루풋을 향상시킨다. 예를 들면, 모범적인 CDMA 시스템에서, 회로 스위칭 링크는 (음성과 같은) 제 1 트래픽 및 제 2 트래픽을 운반하도록 설정될 수 있다. 데이터 세션용 셋업 패킷들은 회로 스위칭 링크 상에 제 2 트래픽으로서 직접 전송될 수 있으므로, 셋업 패킷들을 패킷 스위칭 링크를 통해 전송하는 것과 관련있는 지연을 피할 수 있다. 이 방식에서, 데이터 세션 셋업과 관련있는 왕복 지연 시간(RTT)은 무선 네트워크를 통해 패킷 데이터 네트워크로의 전체 데이터 속도 및 쓰루풋을 향상시키기 위해 줄어들 수 있다.
