Abstract: 본 발명은 액정표시소자에 관한 것으로, 특히 액정표시소자를 구성하는 투명전극을 다층패턴으로 형성시켜 주므로써 종래 단층 액정표시소자에서의 미세화소 형성의 난이함과, 액정판넬을 액정모듈에 장착할 때의 문제점을 해결할 수 있는 다층 투명전극 액정표시소자를 제공하는데 그 목적이 있다. 
     이와 같은 본 발명의 목적은 유리기판위에서 전원으로부터 공급된 전압을 전달하는 하층투명전극단자와, 상기 하층투명전극단자로부터 공급된 전압으로 전기장을 발생하는 하층투명전극과, 상기 하층투명전극 상부에서 SiO 2 및수지재의 재질과 500∼2000Å의 두께범위를 갖고 상하층투명전극을 전기적 절연하는 투명부도체와, 상기 투명부도체 상부에서 외부로부터 공급된 전원을 전달하는 상층투명전극단자와, 상기 상층투명전극단자로부터 상기 하층투명전극화소들간의 간격부에 위치한 화소들에 공급된 전원으로 전기장을 발생하는 상층투명전극을 상·하층 투명전극의 화소간 간격은 단위 화소보다 길게 구성하므로써 달성할 수 있다.

Title: Method for joining spirally wound thermoplastic pipes together
Inventor: BLOMQVIIST GUNNAR
IPC: B29L23/00
Filed: 1992-06-12
Granted: 1999-08-16
Abstract: PCT No. PCT/FI92/00185 Sec. 371 Date Oct. 26, 1993 Sec. 102(e) Date Oct. 26, 1993 PCT Filed Jun. 12, 1992 PCT Pub. No. WO92/22419 PCT Pub. Date Dec. 23, 1992.A method for joining spirally wound thermoplastic pipes is disclosed. The method includes providing a first spirally wound thermoplastic pipe and a second spirally wound thermoplastic pipe, wherein each thermoplastic pipe includes a spirally wound hollow profile. The method further includes placing the end of the first thermoplastic pipe against the end of the second thermoplastic pipe such that a gap having a step is formed between the end surfaces, applying a stainless steel band over the gap and heating the steel band, positioning an extruder and a slide and smoothing organ inside the thermoplastic pipes, heating the end surface of the first thermoplastic pipe and the end surface of the second thermoplastic pipe with a heating means, and extruding melted thermoplastic from the extruder and into the gap between the end surfaces and applying pressure to the melted thermoplastic with the slide and smoothing organ. Thereafter, the method includes stopping the heating of the steel band, and, finally, cooling the extruded thermoplastic and removing the steel band after the thermoplastic is cooled whereby the thermoplastic pipes are joined together.

Title: Anchoring device
Inventor: CUE DEANU LUCIAN
IPC: E06C1/34
Filed: 2002-08-15
Abstract: The invention relates to an anchoring device used for climbing up and down the pillars, by claws. According to the invention, the device consists of a cable (1) clamped at an end, by means of a crimping piece (2), on a coupling piece (3) which has an orifice (a) wherethrough there passes the other end of the cable (1), said end having an eye (b) crimping by a crimping piece (4), the coupling piece (3) having fixed a gripping shank (5) for fixing in the handling rod, and thegripping shank (5) has an arm (C).
