Title: Reducing distortion in r.f. power amplifiers
Inventor: MCGANN MELVYN
IPC: H03F1/32
Filed: 1990-12-06
Abstract: A high frequency SSB radio transmitter has an envelope amplitude modulator 3 for varying the envelope of an r.f. signal source based on an error signal from envelope detectors 5, 6 detecting the envelope of the input and output waveform. It also has a phase modulator 4 for varying the phase of the input waveform based on differences detected in phase detector 10 between the instantaneous phase of the input and output r.f. signal. A signal derived from the error signal controls an amplitude modulator 10 in a subsidiary feedback loop to maintain the size of the envelopes detected by detectors 5 and 6 the same, in order that difference amplifier 7 may operate effectively. Rapid discrepancies between the detected envelopes 5 and 6 occurring within an envelope can then be corrected by amplitude modulator 3. <IMAGE>

Title: Temperature-controlled fan drive coupling
Inventor: KIKUCHI YASUHEI
IPC: F16D31/06
Filed: 1991-04-26
Abstract: A temperature-controlled coupling for temperature-dependent driving a cooling fan of an internal combustion engine comprises a drive input shaft (I) having a rotor (2) thereon, a housing (6) for supporting a cooling fan (9), a plurality of radial vanes accommodated within the rotor, and a valve member (11) within the housing.
