摘要:
A door structure for preventing water leakage is disclosed. The door structure comprises two sides pillars having an opening at the side and having frame with hollow passage and a waterproof stripe being disposed at the front side of the passage and a pressing stripe being provided at the inner side, the side end face of the side pillar being a plurality of isolated pressing seat having screw holes mounted with a bolt shaft coupled to the pressing stripe, the external side of the side pillar being an engaging slot having mounted with a waterproof plate, the engaging slot engaged with an engaging pillar having an external side mounted with a waterproof plate, screw nuts being used to mount the side pillars to the wall or pillar body of the entrance/opening to the building, the bottom side of the side pillar being a waterproof pad; and a plurality of gating plates being elongated plate body having recesses at the bottom side and the upper side being protruded engaging stripe, and the end face of the recess provided with a waterproof plate and the recess at the lowest gate plate being a waterproof stripe, and a flat pad being provided to the ground, thereby the side pillars allow the gate plates to stack to form a sealed waterproof wall.
摘要:
In a synchronous code division multiple access (SCDMA) time division duplex (TDD) communication system, a remote terminal uses both open loop and closed loop techniques for synchronization with a base station. The timing of reception of information by tile remote terminal is performed with an open loop technique, while the timing of transmissions from the terminal is performed with a closed loop technique. Furthermore, a clock locked loop in the terminal compensates for differences between clocks of the terminal and the base station. The clock locked loop responds to signals from both the aforesaid open loop and closed loop techniques.
