Abstract: 출력 심볼의 논리값에 따라 결정하기 위하여, 여러 값을 갖는 디지탈 신호 수신기는 그 입력 신호를 다수의 결정 한계값과 비교하기 위한 비교기 회로(3)를 포함한다. 그 결정 한계값은 결정 한계값에 비례한 재발생된 신호를 발생시키고, 적응 회로(17)내에 발생된 신호를 입력 신호와 비교하고, 그 비교의 결과를 기초로 하여, 적분기(24)의 입력에 양 혹은 음의 전압을 인가시켜 그 결정 한계값을 적응시켜서 수신된 신호부터 유도된다. 
     결정 한계값의 비적응에 대한 출력 심볼의 논리값에 따라 에러의 결정을 피하기 위해, 그 결정 한계값의 적응은 그 적응이 에러되는 것을 방지하게 된다. 그 적응이 에러된다면, 배타-OR 게이트(21)의 출력은 1과 같게 되고, 그 결과, 스위치(23)가 상태(a)로 이동되기 때문에, 반전 적분기의 입력 신호는 0과 동일하게 되어 결정 한계값을 일정하게 유지된다.

Title: Process for the preparation of sintering apatite ceramics
Inventor: KIM SU-RYONG
IPC: C04B35/447
Filed: 1992-12-28
Granted: 1995-09-23
Abstract: The porous calcium phosphate ceramics sintered body is manufactured by calcinting a desirable amount of an apatite hydroxide powder of 10-20 micrometer average particle diameter at 700-1200 deg.C. to make a calcinted powder, adding 10-50 wt.pts(parts) of the apatite hydroxide powder to the calcinted powder, mixing them in the ball mill, molding the mixed powder in the metal mold at 400-800 kg/cm2 pressure, and sintering the molded article at 1050-1350 deg.C. The sintered body has 0.01-10 micrometer averge pore diameter and 5-40 vol.% porosity, and is used as a biomedical material.
Patent KR-100192926-B1 (KR)
Title: Quantum well structures
Inventor: BURT MICHAEL GRAHAM
IPC: G02F1/35
Filed: 1990-09-04
Granted: 1999-06-15
Abstract: By forming quantum well (QW) structures with two different heterojunctions having different band offsets it is possible to form QWs having built-in dipoles. The presence of a built-in dipole in a narrow enough well results in QWs having absorption edges which, unlike those of conventional QWs, can be shifted to the blue by application of an electric field of appropriate polarity.

Title: Capacitor manufacture method of semiconductor dram cell
Inventor: PARK NAM-KYU
IPC: H01L27/108
Filed: 1993-01-04
Granted: 1996-12-07
Abstract: classifying a field region and an active region on a semiconductor substrate(51) to define a region(57) to form a capacitor node to grow a thick oxide film(58) on the region(57); forming a gate electrode and a source/drain region to deposit an insulating oxide film to open the region(57) to form the capacitor node and wet-etching of the oxide neighboring on the thick oxide(58) film; depositing a polysilicon to form a node electrode of the capacitor to form the node electrode(70) by etching the node polysilicon; and forming a dielectric film and a plate electrode of the capacitor on the surface of the node electrode(70).

Title: 8/11 decoder
Inventor: LEE CHANG-UI
IPC: H03M13/00
Filed: 1993-03-23
Granted: 1995-07-31
Abstract: The device comprises a serial to parallel shift register (200) for converting a serial coded block of 11 bit into a block of 10 bit, excluding the top bit, to output, a lookup table (220) for outputting parallel data block of 8 bit corresponding to the 10 bit block, a parrel to serial shift register (240), a "0" discriminator (202) for detecting 0 (ooH) of the 8 bit data to generate a control signal of switching-on, a switch (204) for passing output signal of a lookup table (220), a delay (206) for delaying 10bit output data of the serial to parallel shift register (200), and an error flag generator (208) for comparing data corresponding to the 0 (00H) with the delayed data to generate an error flag in case of the discord.
