Title: 155mbps system of ds1-nas(1.544mbps)
Inventor: CHOE SON-HAK
IPC: H04J3/00
Filed: 1991-12-30
Granted: 1994-10-17
Abstract: The multiplexer connects asynchronous DSI-NAS (155Mbps) signal to a synchronous multiplexing unit and forms TUG21 signal out of the VC11 signal mapping and the TU11 pointer processing, and extracts DSI-NAS dependent signal. The multiplexer extracts DSI-NAS dependent signal through the reverse processing. This device is composed of a Line Interface Unit (1), a VC11 ASIC (2), a Tributary Unit Pointer Processor ASIC (3), a clock generator (4), a board processor (5), a clock monitor (6), a LOS, LOP, AIS detector (7) and a loop-back function block (8).

Abstract: 본 발명은 RBa 2 Cu 3 O 7 형 산화물초전도체(단, R은 Y 및 란타니드계열희토류원소로 이루어지는 군으로부터 선택되는 1종 이상의 원소)의 특징인 높은 임계원소와, RBa 2 Cu 4 O 8 형 산화물초전도체의 특징인 고온도에서의 안정성이라고 하는 양 특성을 구비한 산화물초전도체를 제공하는 것으로, RBa 2 Cu 4 O 8 으로 표시되는 산화물에 있어서, R의 일부를 Ca로 치환하는 것에 의해서 (Ca의 치환율은 R에 대하여 0.1∼50원자 % ) 실현한 것이다. 또한, 상기 산화물초전도체는 여러 가지 방법에 의해 제조될 수 있는데 그 중에서, 원료분말을 열간정수압처리법에 의하여 소결하는 수단이 유효하고. 단지 열간정수업처리법을 적용하는 것만으로도 Tc 상승의 효과가 있다. 그러나, 이때, 또한 중간체로서의 산화물(R 1-X Ca x ) Ba 2 Cu 4 O 8 을 생성시키지 않도록 하면, 보다 효율이 좋은 제조가 가능하다. 또한 높은 임계온도와 고온에서의 안정성을 이루어 선제로의 응용이 가능하다.

Abstract: 전압/펄스폭 변환회로에 있어서, 회로소자수를 증가시키지 않고 펄스폭 변조 출력신호의 변화 출력신호의 변화스텝이 그 듀티비에 대응하여 가변이 되도록하여 칩 사이즈의 축소화, 펄스폭제어의 고 정밀도화를 도모한다. 
     기준 주파수신호(S12)보다 대수 클록신호 TCK를 발생하는 대수 클록발생기(65)와 이 대수클록신호 TCK를 계수하여 복수비트의 디지털치를 출력하는 카운터(66)와를 구비한다. 
     또한, 디지털값을 아날로그 신호로 변환하는 D/A 변환기(67)와 상기 D/A 변환기(67)의 출력과 펄스폭 변조제어 전압을 비교하고, 소정의 듀티비를 갖는 펄스폭 변조 출력신호를 생성하는 전압비교기(64)와를 구비한 것이다.
