Title: Inter exchange traffic control method in full electronic switching system
Inventor: SEO WON HO
IPC: H04Q3/66
Filed: 1998-12-31
Abstract: PURPOSE: An inter exchange traffic control method in the full electronic switching system is provided to prevent a call request to an exchange in an overload state previously by notifying an adjacent foreign exchange of the overload state of the exchange. CONSTITUTION: If a call to an exchange(30) from a subscriber(30) is requested(S1), an exchange(10) confirms whether the current state is normal(S2). If the current state is normal, the exchange(10) transfers call requests for the exchange(30) from subscribers to the exchange(30) unlimitedly(S3). If the current is not normal, which indicates an overflow mode, the exchange(10) confirms whether request calls for the exchange(30) are in the range of a traffic limit ratio possible to be accepted in the exchange(30)(S4). The exchange(10) transfers the request calls not in the range of the traffic limit ratio to the exchange(30)(S5). However, for the request calls in the range of the traffic limit ratio, the exchange(10) limits calls(S6).

Abstract: PURPOSE: A method for graphically outputting No.7 signaling point configuration status in the switching system is provided to output the signaling point configuration status of No.7 signal network graphically. CONSTITUTION: If an operator selects a signaling point configuration status graphic menu, an operator terminal transmits a signaling point configuration status graphic start command to a graphic module.

Then, the graphic module checks whether the initial signaling point configuration status data is received from the signaling No.7. In case that the initial signaling point configuration status data is not received from the signaling No.7, the graphic module checks whether a preset setting time lapsed away. If the preset setting time lapsed away, the graphic module transmits a signaling point configuration status graphic output impossible message. Accordingly, the operator terminal outputs the signaling point configuration status graphic output impossible message. If the initial signaling point configuration status data is received from the signaling No.7 within the setting time, the graphic module transmits the initial signaling point configuration status data to the operator terminal. The operator terminal outputs the initial signaling point configuration data graphically.

     또한, 본 발명의 고분자 화합물을 기재 수지로 사용한 레지스트 재료는 고에너지선에 감응하여 감도, 해상성, 엣칭 내성이 우수하기 때문에, 전자선 및 원자외선에 의한 미세 가공에 유용하다.  특히, ArF 엑시머 레이저, KrF 엑시머 레이저의 노광 파장에서의 흡수가 작기 때문에 미세하면서 기판에 대해서 수직인 패턴을 용이하게 형성할 수 있다는 특징을 갖는다.

Title: Binder for coating composition
Inventor: RPSBAERNE
IPC: C09D133/06
Filed: 1999-05-21
Abstract: PURPOSE: The binder composition is provided which has thixotropic properties. CONSTITUTION: The binder for coating composition comprises carboxy terminated aliphatic ester, obtained from an automatic oxidative aliphatic acid, polyol and carboxy compound, ethylenic unsaturated carboxylic acid and ethylenic unsaturated carboxylic acid ester. Thus, 130.8 parts by weight of sunflower aliphatic acid and 32.7 parts by weight of conjugated aliphatic acid are reacted with 41.8 parts by weight of ditrimethylol propane. 47.3 parts by weight of methacrylic acid, 181.8 parts by weight of methyl methacrylate, 131.3 parts by weight of butyl methacrylate, 25.4 parts by weight of butyl acrylate, 16.7 parts by weight of t-butyl perbenzoate are mixed, followed by addition of the aliphatic acid ester for 3- 4 hours to give the coating composition.
