Abstract: 본원 발명의 펄스신호발생회로는 입력단자에 부여된 입력신호를 지연시키기 위해 서로 직렬 접속되어 배설된 복수단의 지연게이트와, 상기 지연게이트를 통과한 신호를 소정의 타이밍으로 도출하기 위해 상기 복수단의 지연게이트의 각 단 사이에 각각 접속된 제1의 차동접속회로와, 상기 제1의 차동접속회로로부터 출력되는 신호를 캐스코드앰프(cascode amplifier)에 공통으로 공급하기 위해 배설된 제1 및 제2의 입력선과, 상기 제1의 차동접속회로를 구성하는 한쌍의 트랜지스터의 각각에 부여되는 입력신호와 같은 입력신호가 부여되는 한쌍의 트랜지스터를 가지고, 이들 트랜지스터의 출력이 상기 제1의 차동접속회로의 트랜지스터의 출력과 역극성(逆極性)이 되도록 상기 제1 및 제2의 입력선에 접속되어 있는 제2의 차동접속회로를 구비하는 것을 특징으로 한다. 따라서, 본원 발명의 펄스신호발생회로는 형성가능한 최소펄스폭을 작게 할 수 있는 동시에, 초고속으로 동작시켜도 지터(jitter)가 발생하지 않도록 하며, 또한 집적회로의 내부에 형성되는 저항기의 저항치의 불균일 등으로 인해 지연시간이 불균일 해지는 것을 방지하고, 1게이트당의 지연시간을 일정하게 할 수 있다.

Title: Multi-access system using pilot signal in ds communications and accessing method therefor
Inventor: KIM JE-U
IPC: H04B1/7085
Filed: 1992-01-16
Granted: 1994-08-22
Abstract: The apparatus and method decreases interference between PN codes during multi-connection by using two PN (Pseudo Noise) code and pilot signal. The apparatus includes a first PN code generator for generating pilot PN code and multi-connection Pn code, a first delay for delaying multi-connection PN codes with certain phase delay according to subscribers, spreader for spreading user data, a first adder for adding delayed PN codes and user data, a transmitter for transmitting adder output signal, a receiver for receiving the transmitted signal, a second PN code generator for generating pilot PN code and multi-connecting PN codes, a synchronizer for synchronizing clock signal, and a second delay for delaying multi-connecting PN codes.

Title: Method of generating grey-scale pont
Inventor: HAN JAE-JONG
IPC: G06F3/14
Filed: 1992-02-14
Granted: 1994-08-25
Abstract: The gray scale font generating method comprises the steps of calling contour data stored in a character generator, forming a point list indicating the position of character contours on a flag buffer by scaling and scanning conversion, and forming a gray scale font by gray scale converting the point list, thereby obtaining high processing speed.

Title: Purified propolis-extract and its preparation and uses
Inventor: HAMADA SHOICH
IPC: A23L2/66
Filed: 1992-08-24
Granted: 2000-02-01
Abstract: Disclosed is a novel purified propolis-extract which contains the effective components of propolis in a readily absorvable- and utilizable-form in vivo, as well as having an absorbance ratio (A310/A660) of higher than 4,000 and having a relatively-high quality and a satisfiable handleability, color, flavor, taste and antiseptic activity. The purified propolis-extract is prepared by a process comprising decreasing a readily water-soluble organic solvent in its aqueous high-concentration solution containing a crude propolis-extract to a prescribed concentration to form an upper-layer liquid containing the effective components of propolis and a lower-layer liquid containing a viscous sediment, and separating and recoverying the upper-layer liquid.
