Title: Fm stereo receiver
Inventor: KAWAKAMI YASUO
IPC: H04H40/72
Filed: 1988-04-11
Abstract: PURPOSE:To prevent a new high level noise due to the elimination of pulse noise by using a gate means so as to interrupt a composite signal supply to a stereo demodulation means at the detection of pulse noise so as not to use a sub signal component for stereo demodulation. CONSTITUTION:When a pulse noise is included in an FM detection signal outputted from an FM detection circuit 4 and detected by a pulse noise detection circuit 9 and a noise detection signal is generated, both gate circuits 6, 15 are interrupted. An output signal level of a delay circuit 5 just before the interruption of the gate circuit is fed from a level holding circuit 7 to adders 19, 20, since no level holding circuit is provided on the output of the gate circuit 15, the level is not fed to multipliers 17, 18. Thus, no sub signal component is extracted and then the signal is not fed to the adders 19, 20. Thus, a main signal component is outputted from the adders 19, 20 as the audio component. Then the sub signal component is not used for stereo demodulation at the detection of pulse noise.

A gas which is sucked into a pipe 10 is discharged via a six-way changeover valve 21, a calibration tube 24 and the selector 8, and the gas is filled into the calibration tube 24 by a gas of interest. On the other hand, hydrogen gas from a hydrogen bomb 25 reaches a column 27 via a flowmeter 26 and the calibration tube 24, and a sample gas in the measuring tube 24 is purged by the hydrogen gas. The gas which has passed the column 27 is passed through a metallizer 28 so as to be analyzed by a flame ionization detector 29. The detected gas is determined by a data processor 30 by comparing it with a standard gas composition. Thereby, a time-dependent change in a gas composition is traced, and the spontaneous ignition of the coal is alarmed at a prescribed gas concentration.
