Title: Digital modulator with compensation
Inventor: LEWIS J BUANATSUTA
IPC: H04B1/04
Filed: 1997-08-04
Abstract: PROBLEM TO BE SOLVED: To provide a digital modulator that generates a modulated signal with a small peak versus mean power ratio in order to suppress both of power consumption and the cost of a communication system transmitter. SOLUTION: In the digital modulator with compensation, a digital bit stream from a microphone 705, voice coders 706, 708, and a channel encoder 707 is fed to the encoder, in which the bit stream is converted into an I/Q pulse with phase shift keying. A code converter 730 takes notice of a prescribed object code sequence contributing to a high peak versus mean power ratio as to when it is given to the encoder 707 and instructs it to I/Q signal compensation amplifiers 734 or compensation filters 737 to allow it to filter the I/Q pulse when the object code sequence is in existence. The filtered I/Q signal is fed to a quadrature modulator 790, in which the signal is RF-modulated.  A negative effect of the sequence onto the peak versus average power ratio is reduced by compensating the object code sequence so as to improve the efficiency of a power amplifier 795 thereby extending the service life of a battery of a communication equipment.

Title: Heat exchange type blower
Inventor: YAMAMOTO TOSHIYOSHI
IPC: F28F5/04
Filed: 1985-10-04
Abstract: PURPOSE:To reduce the blasting loss and to efficiently perform the heat exchange by forming the blade portion of an impeller into a corrugated shape having radial grooves forming blast paths on both surfaces, and forming the grooves on both surfaces of the blade portion so that air flows through grooves on both surfaces in a manner adjacent to each other. CONSTITUTION:Suction ports 9 and 10, exhaust ports 11 and 12 and a partitioning plate 14 of air currents 7 and 8 flowing into both surfaces of an impeller, separate the air currents 7 and 8. In this case, when the impeller is rotated around a rotary shaft 15, two kinds of air currents 7 and 8 sucked up in the vicinity of the center of both surfaces of the impeller flow in an adjacent manner through grooves 2a and 2b on both surfaces of the impeller portion. As a result, the air currents are subjected to heat exchange by the heat conduction of the blade portion 2, and thereafter sent out through exhaust ports 11 and 12. Thus, since air which has flowed into the grooves 2a and 2b on both surfaces of the blade portion 2, flows along the wall surfaces of grooves on both surface without generating a dead space, the heat exchange surface can be utilized effectively and the blast loss is small, thus the heat exchange is efficiently performed.
