Abstract: PURPOSE: A radio frequency transmission/reception end unit and a method for forming a shape of a base station using the same are provided so that a possessing area, size and production cost of the end unit can be considerably reduced by embodying a single end unit with a circulator. CONSTITUTION: A coupler(201) transmits a signal between a transmission antenna(100) and a circulator(202). The circulator(202) transmits the output signal from the coupler(201) to a reception bandpass filter(203), and also transmits the transmission signal from a transmission bandpass filter(206) to the coupler(201). The reception bandpass filter(203) receives two channel signals from the circulator(202), and then filters elements of the two reception signals except for desired signals. A low noise amplifier(204) amplifies the output signal from the reception bandpass filter(203). A channel division divider(205) divides the output signal from the low noise amplifier(204). The transmission bandpass filter(206) filters unnecessary elements of the channel transmission signal except for the RF signal band, and inputs the resultant signal to the circulator(202). As the result, the single end unit can be embodied to decrease a possessing area. Moreover, redundant components such as a coupler and an antenna are removed to remarkably cut down expenses in installing a base station.

Abstract: PURPOSE: A filtration system is provided, of the type wherein a stack of rotatable membrane packs is spaced by separator elements to leave gaps through which feed fluid moves, which produces enhanced filtration CONSTITUTION: A filtration apparatus is provided, of the type that includes a stack of rapidly rotating membrane packs (32) and a stack of stationary separator elements (36A, 36B) interleaved with the membrane packs to leave thin gaps (40A, 40B) between them, which obtains the advantages of both series-connected and parallel-connected systems. A feed conduit (82) connects the radially outer end (110) of the gaps, to carry feed fluid into and out of each gap. The rapidly rotating membrane packs cause radially outward flow near their surfaces, which causes radially inward flow (102) near the surfaces of the stationary elements, to cause fluid flow radially inwardly and then outwardly through each gap. The stationary elements have apertures (131-138) to equalize the pressure on opposite sides thereof and to promote fluid shear at the membrane surfaces. An accumulator (140) is coupled to the feed inlet (12) to maintain feed fluid pressure during an abnormal loss of feed fluid pressure, for the time required to stop rotation of the stack of membrane packs.
