Title: Method for link adaptation using Hybrid Automatic Repeat Request in reverse link
Inventor: KIM GI JUN
IPC: H04B7/26
Filed: 2001-09-10
Abstract: PURPOSE: A link adaptation method by using a reverse link HARQ(Hybrid Automatic Repeat reQuest) type is provided to effectively control a power and a data rate in a reverse link. CONSTITUTION: A terminal receives an RRC(Reverse Rate Control) bit generated in a base station in the ith frame time, and decides an effective data rate(Reff(i)) according to the RRC bit(S11). The terminal maintains or reduces the effective data rate(Reff(i)) according to its state although the terminal receives a command for increasing the data rate from the base station through the RRC bit(S12,S13). The terminal controls a dedicated data rate of a reverse link and updates the effective data rate(Reff(i)) according to its state(S14-S16). The terminal checks over whether a reception terminal transmits an acknowledgement/negative acknowledgement command about the (i-D)th R-NPDCH(Reverse-New Packet Data CHannel) frame(S18). If the terminal receives the negative acknowledgement command about the (i-D)th R-NPDCH frame, a data rate(DR_RPDCH(i)) of an R-RPDCH(Reverse-Retransmission Packet Data CHannel) transmitted in the ith frame time is updated as a data rate(DR_NPDCH(i-D)) of the R-NPDCH transmitted in the (i-D)th frame time(S19). The terminal compares the updated effective data rate(Reff(i)) with the data rate(DR_NPDCH(i-D))(S20). If the effective data rate(Reff(i)) is greater than or same to the data rate(DR_NPDCH(i-D)), the terminal sets the data rate(DR_NPDCH(i-D)) as the effective data rate(Reff(i))(S22).

Title: Compressing portion for hermetic compressor
Inventor: LEE HYO JAE
IPC: F04B39/00
Filed: 2001-12-18
Abstract: PURPOSE: A compression part of a hermetic compressor is provided to minimize the lateral pressure between a piston and a compression chamber. CONSTITUTION: A compression part of a hermetic compressor includes a cylinder block(20) forming a compression chamber(22); a piston(30) having a slant face(31); and a valve assembly(50) installed to the front of the cylinder block, to control the inflow and outflow of an actuating fluid. The tip of the piston is formed as the slant surface and the predetermined moment is formed by receiving the pressure of the inside of the compression chamber. The moment compensates the moment produced to the piston in a compression stroke, through eccentric rotation of an eccentric pin(42) of a crankshaft. The dead volume of the compression chamber is minimized if the slant surface of the piston and the valve assembly are installed at stated intervals. Thus, lateral pressure is not produced to the piston and exact rectilinear reciprocation is performed inside the compression chamber. Accordingly, wear of the side of the piston or the inner wall of the corresponding compression chamber is prevented and the durability and reliability in action are improved.
