Abstract: PURPOSE: A redundancy decoder of a semiconductor memory device is provided to reduce a current flowing from a supply voltage to a ground by using an ATD(Address Transition Detection) pulse generated whenever an external address(or data) transits. CONSTITUTION: The redundancy decoder includes a selective pull-up/pull-down portion(20), a selective pull-down portion(30), an ATD pulse inverting portion(60), a selective latch portion(70) and a redundancy cell driving signal generator(40). The selective pull-up/pull-down portion pulls up a reference node when a redundancy decoder enable signal, a chip selection signal and the ATD pulse are enabled, and pulls down the reference node when the chip selection signal is disabled. The selective pull-down portion has a plurality of fuses selectively cut according to address signals of predetermined failed memory cells when a master fuse is cut, maintains a voltage level of the reference node pulled up by the selective pull-up/pull-down portion when the address signals of the predetermined failed memory cells are applied in a state that the fuses are cut, and pulls down the reference node when the other address signals except the address signals of the predetermined failed memory cells are applied. The ATD pulse inverting portion inverts the ATD pulse. The selective latch portion latches the voltage of the reference node when the ATD pulse and an inverted ATD pulse are disabled, and does not latch the voltage of the reference node when the ATD pulse and the inverted ATD pulse. The redundancy cell driving signal generator generates a redundancy cell which is enabled by the pulled up voltage of the reference node latched by the selective latch portion and generates a redundancy cell driving signal activating a redundancy cell replaced with the failed memory cell.

Title: Preparation of permanent color inks from water-soluble colorants using specific phosphonium salts
Inventor: GANAPATHIAPPAN SIVAPACKIA
IPC: C09D11/00
Filed: 1999-10-09
Abstract: PURPOSE: Ink compositions containing water-soluble dyes that are color-permanent, particularly, water-fast is provided. CONSTITUTION: Water-fastness in aqueous ink-jet inks containing water-soluble dyes is achieved by using a specific ionic species having a charge opposite to that on the dye molecule. Anionic dyes typically contain sulfonate (or carboxylate) anionic groups. Using at least one specific ionic species of opposite charge, specifically, phosphonium salts, causes the colorant components to "crash" or precipitate out of the water-based ink onto the print medium due to the formation of a suitable charge complex between the ionic parts of the dye and the opposite charge of the counter-ion species. Other positively charged salts, such as quaternary ammonium salts, carbonium salts, iodonium salts, sulfonium salts, and pyrillium salts may be used to improve aqueous dispersion stability and thus printability. Such additional cationic salt partially replaces the phosphonium salt(s). Alternatively, certain surfactants, such as aromatic ethoxylates, polyethylene oxide ethers, or polypropylene oxide ethers may be used to improve print quality.

Title: 소형 구조물을 이용한 그물형 방파 시스템
Inventor: KIM JONG HYEON
IPC: E02B3/06
Filed: 1999-12-08
Abstract: 현재 우리 나라 대부분의 상항, 공업항, 어항, 군항 등에 건설된 방파제는 중력식(매립식, 고정식) 방파제이다. 이러한 중력식 구조물의 기능은 파랑제어 또는 표사 제어라고 하는 방재보전 개발을 목적으로 한다. 그러나, 최근 보다 넓은 해역공간의 확보와 이용 및 심해역의 개발로 인하여 해양 구조물 설치대상 해역이 점점 심해역으로 향하고 있고, 경제발전에 따른 인간생활의 질적 향상으로 바다에서의 Recreation 과 Resort, 해역의 쾌적한 자연환경 보전과 해역환경의 개선 및 Water-front의 개발에 대한 필요성이 강조되고 있다. 따라서, 기존의 중력식 구조물로서는 이러한 상황변화에 대처할 수 없을 뿐만 아니라, 이를 위해서는 막대한 건설비용이 소요된다. 
     더구나, 이러한 중력식 방파제는 외항과 내항의 원할한 해수 교환을 방해하여 항만내 수질악화의 원인이 되며, 건설기간동안 여러 가지 민원발생 요인들을 가지고 있다. 또한, 쇄석, 인공블록, 테트라포트, 상치콘크리트 등이 주 건설재료이므로 거의 매년 발생하는 자연 재해로 인한 피해 복구에는 상당한 재원과 시간이 소요되는 실정이다. 따라서, 이러한 중력식 방파제의 한계를 극복할 수 있는 대체 구조물로서, 부유식 방파제의 필요성이 점차 확산되고 있는 현실이다. 
     이에 본사가 개발한 "다목적용 그물형 부유식 방파제"는 현재 중력식 방파제의 설치로 인하여 발생하는 항만 내 오염, 과도한 재원, 장기간의 건설기간에 따른 여러 가지 문제점을 해결할 수 있다. 뿐만 아니라, 수심의 제한이 없고, 해저 지질 조건의 영향을 받지 않아 설치와 철거가 용이하다. 그리고 일정 기간 사용 후 다른 곳으로 이동할 수 있고, 재사용이 가능하며, 방파제의 설치 위치 오류에 대한 수정이 간편하다.  또한 관광·레져 등의 사업과 연계한 어촌의 소득 증대를 가져오며, 다른 해양플랜트( 관측, 연구용 부이, 무인등대 등 )를 적용할 수 있는 장점을 가지고 있다. 
     이 "다목적용 그물형 부유식 방파제"는 설계파고가 5∼10m인 해역에 Pontoon Type 방파제를 실용화함에 있어 예상되는 계류 방법 등과 같은 어려움들을 해결하기 위하여, 일체형이 아닌 그물형으로 하고, 이 그물형 부유식 방파제에 대한 기초 실험 및 연구를 수행하였다. 그 결과 단파장에서는 입사파고의 90%이상, 장파장에서는 80%이상의 방파효율을 달성함으로써 중력식 방파제보다 더 나은 결과를 얻을 수 있었다. 이러한 필요성에도 불구하고, 일본, 영국 등의 일부 해양 선진국에서 실용화한 부유식 방파제는 설계파고가 1∼2m인 극히 제한적인 해역에, 일체형인 Pontoon Type으로 설치되고 있는 현실이다. 이는 설계파고가 증가하게 되면 부유식 방파제에 작용하는 파 에너지에 의한 파력이 증가하게 되어, 계류시스템을 이용하여 부유식 방파제를 일정한 위치에 계류함에 있어 많은 어려움을 안고 있기 때문이다. 따라서 "다목적용 그물형 부유식 방파제"는 일체형 Pontoon Type 부유식 방파제에 작용하는 큰 파력을 그물형 부유식 방파제 각각의 작은 부유체에 분산시켜서 큰 지지력을 필요로 하지 않는 계류 시스템을 적용하는 신기술이라 할 수 있다. 
     이 시스템은 대형 해양구조물 및 해양시설물을 보호하기 위한 방파제로도 활용이 가능하다. 또한, 해상 공사용으로 그물형 부유식 방파제가 쓰여질 경우, 빠른 시간내, 적은 비용으로도 설치가 가능하며, 해상의 악조건에서도 선박 등이 공사현장에 접안할 수 있도록 파도를 제어해 줌으로써, 공사기간을 단축할 수 있는 등의 이점을 제공한다. 
     나아가, 본 기술은 연안에 설치, 운영되는 양어장, 선착장 및 해상 저장 공간 등의 보호와 해상 도시 및 해상 공항 등의 메가플로트를 보호할 수 있을 뿐만 아니라, 교량 공사, 간척 공사, 항만 공사 등의 해상 공사 작업 공간의 보호로 공기단축 등의 효과가 있다. 
     결국 이러한 "다목적용 그물형 부유식 방파제"는 개발이 선진국의 배타적 기술 독점에서 벗어나 국내 기술력에 의해 기술자립과 경쟁력을 확보할 수 있는 것이라 하겠다. 그리고 그물형 부유식 방파제의 개발은 우리 나라와 같이 국토의 삼면이 바다로 둘러싸인 해양국가에 주어진 해양공간을 효과적으로 활용할 수 있는 기반 기술임과 동시에 국내 신기술을 확보하는 것이라 할 수 있다.
