Abstract: PURPOSE: A method for controlling a shared channel packet service power between an RIU(Radio Interface Unit) and an RP(Radio Port) of a WLL(Wireless Local Loop) is provided to make many RIUs sharing one packet traffic channel use a reverse packet traffic channel by dividing time to each other, and to make each RIU perform power control during a time for transmitting reverse packet data only. CONSTITUTION: If a WLL(Wireless Local Loop) RIU(Radio Interface Unit) requests time slots of a shared packet traffic channel and a packet signal channel, a WLL RP(Radio Port) decides an initial traffic power and transmits the initial traffic power to the WLL RIU(ST11). The WLL RIU controls power of the signal channel relating to an allocated time slot by packet traffic power information, and transmits reverse data to the RP(ST12,ST13). The RP measures a signal strength of the received signal channel, and generates transmission power control information of the WLL RIU, then progresses to the steps 'ST12,ST13'(ST14).

Abstract: PURPOSE: Preventing structure of gas heating in a linear compressor is provided to minimize heated refrigerant gas sucked into a compression space of a cylinder by rectilinear reciprocating of a piston in the cylinder. CONSTITUTION: A permanent magnet(32) reciprocates rectilinearly between an inner stator assembly and an outer stator assembly when power is supplied. The rectilinear reciprocating of the permanent magnet is delivered to a piston(100). Thereby, the piston reciprocates in a cylinder. Refrigerant gas is sucked into a suction pipe(2) by rectilinear reciprocating of the piston. The refrigerant gas flows into an insulating tube(90) to be supplied into a compression space of the cylinder through an opened intake valve(41). Then the refrigerant gas is compressed and discharged through a discharge valve assembly. The entire process is repeated. Friction force is generated between the cylinder and the piston. The heat is transferred to the cylinder and the piston but isolated by an insulating space of a fixed sealing portion and outside of the insulating tube. Therefore, the heat is not transferred to the refrigerant gas flowing into the insulating tube.
