Abstract: First, a completed liquid crystal cell made by adhering two substrates with a sealant is loaded into a liquid crystal injection chamber, and then the liquid crystal injection chamber forms a high vacuum by evacuating much of the air from the chamber. The injection hole of the sealant is completely immersed in the liquid crystal material. At this time, the interior of the liquid crystal cell enclosed by the sealant is under high vacuum. Next, non-active gas is injected into the interior of the liquid crystal injection chamber, and then the vacuum in the interior of the chamber is reduced or it is allowed to return to atmospheric pressure. Then, because the interior of the liquid crystal injection chamber is at low vacuum or at atmospheric pressure and the interior of the liquid crystal cell enclosed by the sealant is at high vacuum, the liquid crystal material is injected into the interior of the liquid crystal cell enclosed by the sealant.

Abstract: A sequential path searching method for demodulating a reverse channel in a mobile communication system is disclosed. In case that at least one mobile station maintains connection with a base transceiver station and the system searches an optimal path among multiple of paths which has a great receiving quality, the preferred embodiment of the present invention in a mobile telecommunication system supporting a variable data rate transmission, includes a step of searching multiple paths according to a sequential searching algorithm and avoiding deterioration of demodulation performance on variable data rate transmission.
