Title: Combustion apparatus
Inventor: AKIYAMA TAKASHI
IPC: F23C99/00
Filed: 2000-07-28
Abstract: PROBLEM TO BE SOLVED: To eliminate the difficulty with prior art that in a combustion apparatus employing a rich/lean fuel combustion system non-combusted components are exhausted upon ignition to cause odor of gas and be uncomfortable, and further provide a feeling of unrest that gas might be exploded. SOLUTION: A combustion apparatus 1 comprises a burner body 10 and a burner port member 13. The burner body 10 is fabricated by laminating four metal plate structures 15, 16, 17, 18. In the combustion apparatus 1, fuel gas introduced from a rich gas introduction hole is branched to a lean fuel gas flow passage at a branch portion therein, and a curved passage is provided on a lean fuel gas flow passage after the branch section, and further the lean fuel gas flow passage after the branch section is longer than the rich fuel gas flow passage after the branch section. Therefore, physical distances reaching burner ports of two kinds are different, and after a flame is produced from an auxiliary burner port low concentration fuel gas is injected from a main burner port.  For this, fire is rapidly transferred also to low concentration fuel gas injected from the main burner port, and less unburnt components are exhausted.

Title: Nonlinear distortion compensation circuit and nonlinear distortion compensation method
Inventor: NAGASAKA HIROYUKI
IPC: H03F1/32
Filed: 2000-08-01
Abstract: PROBLEM TO BE SOLVED: To provide a nonlinear distortion compensation circuit that can compensate nonlinear distortion due to high power amplification with high accuracy and small power consumption without the need for a complicated large-scale digital arithmetic circuit or pseudo distortion generating circuit or the like. SOLUTION: The nonlinear distortion compensation circuit extracts a nonlinear distortion component from a modulation signal subjected to nonlinear high output amplification, superimposes a distortion component with an inverted phase of a distortion component of a base band region that is generated by applying quadrature demodulation to the extracted distortion component and converting the resulting component into a base band signal in the base band region onto the base band signal, applies quadrature modulation to the base band signal onto which the inverted distortion component is superimposed, and applies nonlinear high power amplification to the modulated base band signal so as to cancel the nonlinear distortion caused at the nonlinear high power amplification.  Thus, the nonlinear distortion compensation circuit can compensate nonlinear distortion due to high power amplification without using a complicated large-scale digital arithmetic circuit or pseudo distortion generating circuit or the like and reduce the power consumption because of its small circuit scale.
