Abstract: PURPOSE: In a current CDMA(Code Division Multiple Access) system, data transmitted from a BSC(Base Station Controller) every period are stored in a relational database(DB) of each BSC, and the size of the relational DB is fixed. So a hard disk capacity of the BSM(Base Station Manager) is wasted. Thus, a data storing method in a CDMA system is provided to store the data got every period in a relational DB with a flexible size to construct 64 BTS(Base Station Transceiver Systems) and 6 sectors in the CDMA system. CONSTITUTION: When a CDMA system operates 64 BTSs, and the BTS manages 6 sectors, a data storing method comprises three steps. In a first step, the BSD makes a relational DB with the flexible size in the BSC unit. In a second step, the base station or the BSC transmits and processes the periodical data to the BSM, And, in a last step the BSM stores the processed data transmitted from the BSC into the relational DB of flexible size.

Abstract: PURPOSE: A method for forming a color filter of an image sensor is provided so that a lifting phenomenon of a color filter resist can be prevented or restricted, without generating a residue or deforming a pattern shape. CONSTITUTION: Firstly, a substrate(31) generally consisting of an insulation film is O2 plasma treated, and thus an oxide film or oxide polarity group is chemically adsorbed to the surface(32) of the substrate(31). As a result, a surface free energy is increased. Thereafter, red(R), green(G) and blue(B) color filters are formed by performing a general lithography process. At this time, the free energy has been increased on the surface(32) of the substrate(31), and thus a color filter pattern is not or rarely lifted in a developing process. In the lithography process, a pre-bake temperature and an exposure time of the resist are determined not to generate a residue or deform a pattern shape. Here, the pre-bake temperature and the exposure time of the resist may be varied according to a thickness and kind of the resist. Accordingly, the lifting phenomenon of the color filter resist can be efficiently prevented or restricted.

Abstract: 본 발명은 시동(始動) 잠금장치에 관한 것으로, 더욱 상세하게는 자동차의 제동 페달에 연결된 제동 연결기구(Linkage)에 기계식으로 설치하거나 유압식 제동장치를 구성하는 마스터 실린더(Master Cylinder)에 설치하여 운전자가 제동을 할 때에는 자동적으로 제동등(制動燈)이 점등(點燈)되도록 해 주는 기존의 제동 스위치를 개량하여, 스위치의 접점(接點)을 한쌍 더 추가함으로써 운전자가 제동을 하기 위하여 제동 페달을 밟을 때에 제동등이 점등됨과 동시에 자동차의 시동회로(始動回路)를 폐회로(閉回路)로 만들어 주어, 제동페달을 밟지 않고는 엔진시동을 걸 수 없도록 하여 자동변속기 장착 차량의 급발진사고를 획기적으로 예방할 수 있는, 시동(始動) 잠금장치에 관한 것이다.
