Title: Noise elimination circuit
Inventor: ASAMI TAKAO
IPC: H04B1/10
Filed: 1993-03-15
Abstract: PURPOSE:To prevent malfunction of a gate circuit due to harmonic distortion caused by an IF amplifier independently of noise in the noise elimination circuit. CONSTITUTION:A front end 1 and a received IF signal from an IF amplifier 2 are fed to a high pass filter 13, its output is given to a noise detector 15, a pulse from a monostable multivibrator 16 is outputted to a gate circuit 11 in response to a detection signal to activate the circuit thereby eliminating noise. On the occurrence of harmonic distortion, when the front end 1 provides an output of a broad band AGC output voltage to the high pass filter 13, the cut-off frequency is revised to decrease noise detection sensitivity thereby preventing malfunction of the gate circuit due to distortion other than noise.

Abstract: PURPOSE: To apply proper gradation correction to a color picture by using the read values of a color chart and a prescribed pattern. CONSTITUTION: In the case of executing automatic gradation correction, a CPU 313 allows a reader part 301 to read out a color chart and a test pattern and finds out a correction value to be set up in a printer gradation correcting circuit 316 by operation based upon the read results. In the case of correcting a C color component e.g. input masking processing is turned off, R, G and B values obtained by reading out the C color part of the color chart are respectively set up as Rco, Gco, Bco and R, G and B values obtained by reading out the C color part with density Di of the test pattern are set up as Rci, Gci, Bci.  Density is measured based upon an R signal, and when a C color component signal with density Dci is inputted, the contents of a table in the circuit 316 are changed so that the C color component signal with a prescribed value is outputted to correct the gradation of a printer part.

Abstract: PURPOSE: To effectively remove harmful substances and also to lessen the concentration of harmful substances in water from water strippers and to increase the quantity of water reusable as washing water by using water strippers for evaporating harmful substances in washing water. CONSTITUTION: A crude gasified gas 1 enters a dust collector 3 where dust therein is caught by washing water and removed, and the washing water after dust removal enters the 1st water stripper 6 through a washing water discharge line 5, and a part of it is evaporated there. On the other hand, after the gas 1 from which dust has been removed is cooled by a gas cooler 4, it is purified through a downstream process. In the gas cooler 4, since the gas 1 is cooled, moisture in the gas 1 or the like is condensed, and this condensate enters the 2nd water stripper 17. Steam delivered through a steam line 10 from the 1st water stripper 6 is introduced into the 2nd water stripper 17 to evaporate a part of water. In this way, the quantity of gas to an off gas treating device and the quantity fo moisture in gas are reduced, and also the quantity of heat in the 2nd water stripper 17 is reduced.
