CONSTITUTION: In a process, a separate FA to a conventional operation FA is increased in the first channel(GROW-CDMA-CH)(203), only data relating to the increased FA is transmitted and a service is not performed. In addition, a process is to perform the service by making the corresponding FA active in the second channel(ACT-CDMA-CH). Two cells are simultaneously serviced in the same base station by using the separate operation frequency bandwidth information (CDMA_CHANNEL_LIST) transformed and being written in the increase of FA. In order to maintain the continuity of the service, a state management block checks periodically the state of the subcell, transmits to a shape management block and updates the library(in steps of 201 and 202). Also, the shape management block checks periodically the state library and attempts again from the check routine of an initial state when receiving information on the subcell state from the state management block(in steps of 211-213).

Abstract: PURPOSE: Muffler structure of a hermetic rotary compressor is provided to minimize pressure pulsation and noise of a valve in a process of discharging high-temperature high-pressure refrigerant gas into a closed vessel. CONSTITUTION: A rolling piston is connected to an eccentric portion of a rotatable shaft. The rolling piston rotates in a cylinder to suck and compress refrigerant gas. The refrigerant gas is discharged by a discharge valve. The high-temperature high-pressure refrigerant gas flows into plural first spaces(S1) and then into plural second spaces(S2) through clearance between inside of a through hole(42) of an internal noise reducing member and a bent portion(53) of an external noise reducing member(50). The refrigerant gas is discharged to a closed vessel through discharge holes between outside of a shaft support portion and the bent portion of the external noise reducing member. Pressure pulsation and valve noise is generated together with the discharged refrigerant gas but reduced in RF(Radio Frequency) noise. Therefore, noise generation is minimized and reliability of a compressor is improved.

Abstract: PURPOSE: A medical implant, tubing and method to provide enhanced X-ray detection intensity in catheters, stents, vascular grafts or other tubular implants. In one aspect the medical implant includes a visually transparent radiopaque polymer and a filler material having a radiopaque component. CONSTITUTION: Figure 4 shows an embodiment resulting from co-extrusion of the visually transparent radiopaque polymer having no filler material and the filler material (filled polymer). In Figure 4, the filler material (filled polymer) is largely isolated and concentrated in one or more segments(40) disposed within the otherwise visually clear tubing of, for example, brominated polymer(10). When the tubing is viewed lengthwise, the segments(40) of filler material tend to form one or more stripes of varying size which extend generally longitudinally along some extent of the tubing, basically parallel to the flow direction within the lumen(30). This embodiment allows the specific placement of radiopaque, yet potentially optically obstructing segments (filled polymer) so as to allow observation of fluid flow while retaining the superior radiopacity of the segments, appearing as stripes within the tubing, wherein concentrated amounts of filler material are disposed. As with the embodiment of Figure 3, a co-extrusion using two extruders with split extrusions may form the striped pattern.
