Abstract: PURPOSE: A method and an apparatus for improving quality of speech signals transmitted over wireless communication facilities are provided to prevent critical frames from being lost and corrupted by detecting these critical frames and improving their robustness before transmitting them. CONSTITUTION: In a wireless communication system, specific frames of encoded speech data transmitted between a base station and a mobile unit, or between a mobile unit and a base station are more critical than other frames. Frames can be determined by the receiving base station or a mobile unit being deleted by the noise or interference in a wireless transmission medium. If the deleted frame can not be regenerated from more than one proceeding frame, the frame not to be regenerated is more critical than a frame which can be regenerated by an extrapolation of data from more than one proceeding frame. Therefore, in every frame, each frame is discriminated as a critical frame or as a non-critical frame. In order to reduce the possibility for a receiver to decide the deletion of the frame, each frame recognized as a critical frame is transmitted in more intense method than the transmission method of a non-critical frame.

Abstract: PURPOSE: A driver of a lubricationless pulse tube refrigerator is provided to maintain rectilinear motion of a piston even at low precision in machining of a drive shaft and the piston and to slide the piston along inside of a cylinder even though side force is applied to the drive shaft. CONSTITUTION: A drive shaft(130) reciprocates rectilinearly by an upper and a lower leaf spring(160,170) when a drive motor is powered on. A piston(150) integral with the drive shaft reciprocates rectilinearly in a cylinder to pump working gas of a refrigeration unit. Thereby, a cryogenic part is formed at a cold heat exchanger of a pulse tube. When the drive shaft is distorted by external force, a flexible bar(140) is bent within a clearance(C) of degree of freedom. Herein, the piston is connected with the flexible bar in the drive shaft but not directly to the drive shaft. Thereby, the piston slides along inside of the cylinder. The piston is twisted freely from motion of the drive shaft as much as the clearance of the flexible bar to do rectilinear motion even though side force is applied to the drive shaft. Therefore, abrasion between the piston and the cylinder is prevented.
