Title: Phase synchronizing device
Inventor: GOTO MITSURU
IPC: H04L7/02
Filed: 1999-01-06
Abstract: PROBLEM TO BE SOLVED: To realize quick synchronism pulling-in by suppressing a difference between the frequency bands of reproducing carriers outputted from a voltage controlled oscillator when there is a modulation signal and when there is no modulation signal to a small level. SOLUTION: A level discrimination circuit 11 is allowed to discriminate whether the input level of a PSK modulation wave or a multi-valued QAM modulation wave is equal to or below a set level or not. When the circuit 11 discriminates that the input level is equal to or below the set level, a switch switches a phase controlled voltage output from an APC detection circuit 7 to a voltage signal generated from a fixed voltage signal generation circuit 8 to input the voltage signal to the voltage controlled oscillator 5.

Title: Rotary compressor
Inventor: NISHIKAWA TAKEHIRO
IPC: F04C18/356
Filed: 1999-01-07
Abstract: PROBLEM TO BE SOLVED: To provide a rotary compressor capable of adopting the conventional fundamental design unchanged substantially even when carbon dioxide is used as a refrigerant. SOLUTION: A compressing means is of a two-stage compression system consisting of a front stage compression element 20 and a rear stage compression element 30. The internal space of a sealed case 13 is coupled with the suction port 31 of the rear stage compressor 30 through a coupling pipe 40, which is fitted with a heat radiator 41. A refrigerant supplied externally to the front stage compression element 20 is compressed thereby and discharged into the sealed case 13 so that the temp. and pressure of the refrigerant are decreased. This refrigerant is fed to the rear stage compression element 30 via the heat radiator 41. At this time, the refrigerant releases the heat at the radiator 41, which decreases the temp. and pressure of the refrigerant still further.  Even if a refrigerant of carbon dioxide is used, therefore, the specified pressure and temp. will never be exceeded, which allows adopting the conventional fundamental design unchanged.
