摘要:
Diamine compound containing specific triazine group, polyamic acid obtained by reacting the diamine compound and tetracarboxylic dianhydride, and liquid crystal alignment film obtained by coating and imidizing the polyamic acid. The liquid crystal alignment film has good heat-resistance, high transparency in visible light region and improved voltage holding ratio. Also, pretilt angle is easily controlled over broad range.

摘要:
A call cut-off detection circuit for a switch and a method of the same are disclosed. The circuit includes a time switch unit switching a first PCM data, a COB processing circuit combining the first PCM data and a first call state data or separating the first PCM data and a second call state data from a second PCM data, a processor writing the first call state data into the COB processing circuit and judging the state of a call cut-off of a channel based on the second call state data separated by the COB processing circuit, and a local link unit connected between the COB processing circuit and a space switch for transmitting and receiving the second PCM data, for thereby implementing a good quality call and enhancing a reliability of the switch by detecting a call cut-off based on a simple method.
