Inventor: SO MIN SEOP
IPC: H04B7/26
Filed: 1999-07-22
Abstract: PURPOSE: A virtual frequency conversion generator in a mobile phone network using a space wave coupling is provided to use a CDMA(Code Division Multiple Access) signal delivered from a base station to generate many CDMA signals(frequency assignments(FAs)), so as to continuously maintain a telephone conversation when a cellular phone user passes through a base station having different FAs and a boundary region between base stations in a CDMA mobile communication system. CONSTITUTION: A receiving antenna(41) receives a CDMA(Code Division Multiple Access) signal source(frequency assignment(FA)) radiated from a base station antenna(40) on a free space. The first frequency converter(43) converts a CDMA signal received from the receiving antenna(41) into an intermediate frequency(IF) signal. The first circulator(42) matches an impedance between the receiving antenna(41) and the first frequency converter(43). The second frequency converter(44) converts the IF signal into an FA signal having a predetermined band width only. A high power amplifier(45) amplifies the FA signal as a high output FA signal. A transmitting antenna(47) transmits the high output FA signal with a cellular phone. The second circulator(46) is formed between the high power amplifier(45) and the transmitting antenna(47), to prevent an impedance matching and a feedback between the high power amplifier(45) and the transmitting antenna(47).

Filed: 1999-08-17
Abstract: PURPOSE: A pipe connector is provided to simplify a connecting and decomposing work without damage to the pipe by producing a nipple and a bushing movably and to excellently prevent water leakage. CONSTITUTION: A pipe connector consists of a bushing(13) forcibly inserted in an inner circumferential face of a pipe(1); a press fastening ring(12) of which bore is resiliently contracted and pressed on an outer circumferential face of the pipe if a slant face(12-1) is pressed by a slant face(10-1) of a fastening nut(10) and a fastening flange(13-3) of the bushing; and a nipple(15) of which front end face presses an O-ring(14) of an O-ring groove. Upon connecting the pipe in a narrow space, a front end of the pipe is resiliently pulled back. The pipe connecting unit(13-1) is inserted while inserting the fastening nut and the press fastening ring in order. The O-ring is inserted in the O-ring groove. When the pipe and the nipple are put coaxially, a female screw unit(10-2) of the fastening nut is combined with a male screw unit(15-1) of the nipple. If the slant face of the fastening nut adheres the press fastening ring to a rear side face of the fastening flange, the press fastening ring is not processed any more. Upon tightening the fastening nut more, the slant face(10-1) contracts the bore of the press fastening ring while sliding along the rear slant face(12-1). Further, a front slant face of the press fastening ring contracts a front bore of the press fastening ring while sliding along the rear slant face of the fastening flange. Thus, the press fastening ring fixes the pipe while pressed on the outer circumferential face of the pipe.
