Inventor: CHANG JIN-KYU
IPC: H04M3/22
Filed: 1988-12-08
Granted: 1992-02-13
Abstract: The  circuit  automatically  controls  various  checking  by sequentially selecting keys. The circuit includes: a plurality  of second key board means (100, 101 and 104) for being turned  on  or off by selecting arbitrary cross points in accordance with control signals supplied from a CPU; and a plurality  of  signal  matching means (102, 103, 106 and 107) for  converting  the  level  of  the control signals of the CPU to a  signal  level  suitable  for  the second key board means (100, 101 and 104). The key inputting state of a key board (90) of the key telephone,  which   corresponds  to the cross point of the second key board means (100, 101 and  104), is checked by the CPU, and is transferred through a buffer circuit (109) to the CPU which judges the state of the operation based  on the furnished data.

Abstract: 본 발명은 파라크실렌을 산화시키고 수성상으로 정제한 뒤 침전시켜 수성상으로부터 정제된 생성물을 회수하고, 그후 수성상 모액을 냉각시키거나 증발시켜 덜 순수한 침전물 및 제2모액을 얻은 뒤 덜 순수한 침전물을 반응 매질에 되돌려보내고 및/또는 제2모액의 물을 사용하여 크루드 고체를 용해시키고 및/또는 제2모액을 처리하여 물을 회수하고 이 회수한 물을 사용하여 수성용액으로부터 회수한 침전물을 세척하여 테레프탈산을 제조하는 것에 관한 것이다. 본 방법은 테레프탈산의 수율이 더 좋아지도록 만들어 물의 사용량을 줄이고 오염된 폐수를 처리하는데 있어서의 문제점들을 축소시킨다.

Abstract: 신호 압축은 임의의 주파수 대역을 인코드하는지 아닌지, 전체 주파수 대역을 얼마나 양호하게 인코드하는지의 여부에 대한 단순 결정을 통해 달성된다. 입력 신호 및 미리 선택된 모델을 기초로 하여, “최소 감지가능 차이”(jnd) 잡음 스펙트럼이 계산된다. 상기 스펙트럼은 입력 신호 주파수 대역의 선정된 수를 선택하기 위한 결정에 사용되는 선택기에 인가된다. 선택된 대역은 동일 대역에서 jnd 에너지에 대해 가장 큰 에너지를 갖는 대역이다. 각 선택된 대역은 인코드되며 수신기로 전송된다. 아날로그 구현 및 디지털 구현이 가능해진다.

Abstract: There is disclosed an improved process for the production of linear alkylbenzene wherein monoolefins are reacted with benzene in a hydrogen fluoride catalyzed reaction followed by recovery of the alkylbenzene. An alumina treatment step is included which removes organic fluoride impurities in order to prevent release of hydrofluoric acid in downstream equipment. It has been discovered that the SO3 sulfonation color of the alkylbenzene is surprisingly improved by the use of a high selectivity basic alumina for this treatment.
