Title: Apparatus for eliminating returning data in half-duplex data communication system
Inventor: LEE HYUN-WOO
IPC: H04L25/02
Filed: 1989-04-29
Granted: 1992-03-20
Abstract: Each of two receiving and transmitting means (12,22) inverts the output data of a transmitting terminal of a data  transmitting apparatus, and, when the inverted data has a first logic, the data appearing on the transmission line  is  supplied  to  a  receiving terminal of the data transmitting apparatus. If the inverted  data has a second logic, the inverted data is supplied to the receiving terminal of the data transmitting apparatus.  Further,  first  and second switching means (14, 24) are switched over, to restore  the output data of the data transmitting apparatus, and to supply  the data to the transmission line. According to the present invention, when forming a semi-dual bidirectional  communication,  a  reverse flow of the data can be prevented by means of a hardware,  thereby alleviating the load of software.

Abstract: 개량된 메모리 모델과 구현이 개시된다. 
     이 메모리 모델은 다중 프로세서에 의해 시작된 메모리 동작에 대한 부분 순서를 제공하기 위해 총 기억순서매김(TSO)와 부분기억순서매김(PSO)을 포함한다. TSO메모리 모델은 기억 및 자동 로드-기억동작에 대해 FIFO 기억버퍼를 표현한다. 이 로드 동작은 FIFO 기억버퍼내에 위치하지 않는다. 
     이 로드동작은 FIFO 기억버퍼에서 동일 위치에 기억된 값에 대해 검사한다; 만약 그 값이 발견되지 않으면 그후 요구된 값이 메모리로 부터 복귀된다. PSO 메모리모델은 또한 기억 및 자동로드기억동작에 대해 기억버퍼를 포함한다. 그러나 TSO 모델과 다르게 PSO 모델에서 기억 버퍼는 FIFO가 아니다. PSO모델에서 프로세서는 소정의 순서대로 기억 및 자동 로드-기억을 시작할수 있다; 그러나 이러한 동작 프로세서에 의해 시작된 순서를 벗어나서 메모리에 의해 실행될수 있다. 이 실행순서는 오직 번지 메칭과 STBAR 동작에 의해서만 보증된다. STBAR 동작에 의해 분리된 두개의 기억동작은 프로세서에 의해 시작된 순서대로 동작을 실행할 것이다. PSO 모델에서 로드 동작은 기억버퍼내에 위치하지 않는다. 로드동작은 우선 기억버퍼내에서 동일 위치에 기억된 값에 대해 검사한다; 만약 그 값이 발견되지 않으면 그후 요구된 값이 메모리로부터 복귀된다.

Waste liquids discharged from the preliminary and main dewatering devices are supplied to an agglutinating reaction tank together with a macromolecular agglutinating reagent and agglutinated substances in the agglutinating reaction tank are treated by the main dewatering device. The agglutinated substances formed on the bottom surface of the agglutinating reaction tank may be treated by a different main dewatering device than said main dewatering device. A necessary amount of the macromolecular agglutinating reagent to be supplied to the agglutinating reaction tank can be reduced, while the dewatering efficiency is not deteriorated. <IMAGE>

Abstract: Reconstituted tobacco sheets manufactured from tobacco dust and binder are described herein. More particularly, the tobacco dust has a mean particle size in the range of from about 60 mesh to about 400 mesh to afford reconstituted tobacco sheets having about 80% to about 90% tobacco content with improved quality and survivability. The reduced particle size of the tobacco dust allows an increase in the solids content of the slurry without an increase in slurry viscosity. The increased solids content reduces the drying load of the cast sheet thereby allowing an increased production rate. The reconstituted tobacco sheets may be prepared from a slurry comprising tobacco dust and binder that may be subjected to a means for removing air trapped within the slurry before casting the slurry into sheets. An apparatus for determining the amount of air trapped within the slurry prepared according to the process of the present invention is also described herein.

Abstract: Vitamin D2 analogs in which a cyclopropane ring is introduced onto the 24-carbon of the side chain of 1 alpha ,25-dihydroxyvitamin D2 and 1 alpha -hydroxyvitamin D2. The compounds are characterized by a marked intestinal calcium transport activity while exhibiting much lower activity than 1 alpha ,25-dihydroxy-vitamin D3 in their ability to mobilize calcium from bone. Because of their preferential calcemic activity, these compounds would be useful for the treatment of diseases where bone formation is desired, such as osteoporosis.

Abstract: 본 발명은, 비대칭 입력 신호를 한 쌍의 대칭 출력 신호 전류로 변환하는 1개의 IC 접속핀만을 필요로 하는 집적화 가능한 변환기 회로에 관한 것이다. 본 변환기 회로는, 고주파에 이르기까지 양호한 노이즈, 이득, 상호 변조 특성을 아울러 갖는 저입력 임피던스를 나타낸다. 변환기 회로의 비대칭 입력 단자는 공통 베이스 트랜지스터의 에미터와 공통 에미터 트랜지스터의 베이스에 공통으로 접속된 노드에 접속된다. 공통 베이스 트랜지스터는 비반전 전류 폴로워로서 작용하고, 공통 에미터 트랜지스터는 반전 상호 임피던스 증폭기로서 작용한다. 입력 신호 전류는 노드와 공통 베이스 트랜지스터를 경유해서 제 1 대칭 출력 단자로 전송되며, 이에 따라서 노드에서 신호 전압이 발생된다. 이 신호 전압은 입력 신호 전류와 역위상인 공통 에미터 트랜지스터의 콜렉터 전류를 변조하여 제 2 출력 단자에 전송한다.

Abstract: The apparatus and method measures the flow rate by scanning the supersonic wave on the pipe with a large diameter. Specially the apparatus and method measures the average flow rate on the overall area of the fluid, and compensates for the supersonic transfer distance and angle caused by physical changes of the fluid and all the delay times of the measurement device. The apparatus comprises a plurality of supersonic wave oscillators(11) installed at holes(11) formed on the inner wall of the pipe(10). The oscillators are arranged along a radial direction by the interval of R(n+1) where R is a radius and n is the number of the holes in order to prevent the interference among the oscillators.
