Title: Fm demodulator
Inventor: HONMA SOICHI
IPC: H03D3/00
Filed: 1992-07-24
Abstract: PURPOSE:To simplify the configuration by using a low pass filter, a phase calculator and a differentiation device based on a signal obtained by sampling an input FM signal by a sampling frequency and its complementary signal. CONSTITUTION:An input FM signal is converted into a digital signal by an A/D converter 1. A complement selector 2 selectively outputs an output signal from the A/D converter 1 as it is or an output multiplying the output signal by (-1). The output of the complement selector 2 is outputted to a delay device 3 and a low pass filter 4. The delay device 3 delays the input signal by a delay being a half of of the delay of the low pass filter 4. An arc tan calculation device 5 obtains a phase component based on a signal from the delay device 3 and the low pass filter 4. The obtained phase component is given to a difference device 6, in which the difference is calculated and a demodulation output is obtained. In this case, the function of the 90 deg. phase shifter is realized by the complement selector 2, the delay device 3 and the low pass filter 4 to adaptively change the pass band in response to the condition such as the input C/N.

As the non-combustible gas, an inert gas e.g. an exhaust gas in a combustion chamber 10 is utilized. Thus, air 12 blown to the combustion chamber 10 is shut off by the partitioning wall 14, and the non-combustible gas is injected into the inside of the partitioning wall 14 through the introducing ports 20. As a result, even when fuel is injected from the nozzle 5, atomized fuel in the inside of the partitioning wall 14 is not ignited by flames 13 in a combustion zone 11. Accordingly, ignition sound to occur at the time of fuel injection can be prevented.

IPC: H01P1/22
Filed: 1996-08-01
Abstract: PROBLEM TO BE SOLVED: To switch a power of a signal sent at a high speed, without momentary interruption. SOLUTION: One of output terminals of a distributer 1, located to an input terminal of a circuit receiving a transmission signal, is connected directly to a synthesizer 4, and the other output terminal is connected to the synthesizer 4 via a switch 2.
