IPC: B01D53/56
Filed: 1993-04-05
Abstract: PURPOSE:To provide wet denitrification for NO contg. gas of low concentration by decomposing nitrite ions in liquid which has absorbed gaseous NO2 to gaseous nitrogen by biological treatment with denitrification bacteria. CONSTITUTION:A liquid which has absorbed NO2 is collected in a tank 3 and the pH of the liquid is held constant on the alkaline side.

Title: Limiting current type oxygen concentration detector compensated for temperature of measured output
Inventor: KONDOU HARUYOSHI
IPC: G01N27/41
Filed: 1981-05-25
Abstract: PURPOSE:To improve the measuring accuracy of oxygen concentration while expanding the range of use by compensating for the temperature with respect to limiting current based on internal resistance in a sensor after the measurement of the two elements. CONSTITUTION:A voltage from an A.C. oscillator 18 is applied to a limiting current type oxygen sensor 1 through a D.C./A.C. overlapped voltage applying section 12 and a current detecting section 13. A current signal detected by a detecting section 13 is separated into a D.C. component (limiting current) and an A.C. component through an A.C./D.c. separation section (HPF and LPF) 14. The A.C. signal is inputted to an internal resistance computing section 15 and an internal resistance is calculated through an output voltage from an A.C. oscillator 18. From the outputs obtained, a temperature correction coefficient is calculated with a temperature correction coefficient computing section 16 and sent to a correction section 17. A temperature compensation is added to a limiting current signal from a separation section 14 and a current proportional to the oxygen concentration is outputted. This improves the accuracy of measuring the oxygen concentration while expanding the range of use.

Title: Fine-grain detector
Inventor: YAMAHA TSUNEO
IPC: G01J1/02
Filed: 1995-03-09
Abstract: PURPOSE:To decrease the detecting errors of fine grains by providing a noise- level forming circuit, which generates the shot-noise effective voltage value based on the current fluctuation of a photodetector, setting the voltage value as a threshold value, and sending the value to a comparator. CONSTITUTION:In a first threshold-value setting part 41, the output signals of (n) pieces of first operation amplifiers 21-1-21-n are added in an adding operation amplifier 411 through resistors (r). The shot noise N is extracted with a capacitor CN and inputted into an effective-value converting circuit 412. At this time, the effective,value N is computed in this circuit and set as the input for comparators as the threshold value V1 for the first comparators 24-1-24-n. The DC is cut off with capacitors C1, in each output signal of the first operation amplifiers 21-1-21-n. The signal components for scattered light LR are inputted into the first comparators 24-1-24-n and compared with the threshold value V1, and the minute fine grains are detected. By the same way, the threshold value V2 is obtained in a second threshold-value setting part 42. Since the adequate threshold value is set in each comparator in this way, the detecting errors can be decreased.

Title: Laser irradiation in laser isotope separation method
Inventor: TAKEUCHI KAZUO
IPC: B01D59/34
Filed: 1987-03-31
Abstract: PURPOSE:To sufficiently utilize the benefit obtained by the use of an ultrasonic nozzle and to prevent the damage of an optical window, by allowing two or more kinds of laser beams different in a wavelength irradiating a working substance to cross each other. CONSTITUTION:Two kinds of infrared laser beams 2, 3 different in a wavelength are allowed to irradiate the working substance in an ultrasonic nozzle 1 in such a state that the optical axes thereof cross each other at a right angle. The overlapped part of the laser beams 2, 3 is limited to the central part of the nozzle 2 and no dissociation reaction is induced in the vicinity of the inside part of optical windows 4, 4' permitting the transmission of the laser beams 2, 3. As a result, since no infrared multiple photo dissociation is induced in the gaseous working substance not supercooled in the vicinity of the inner wall of the ultrasonic nozzle 1 or low pressure reaction container 7, the benefit obtained by the use of the ultrasonic nozzle 1 can be sufficiently obtained. Further, since it is avoided that highly intensity infrared laser beam is applied to the optical windows 4, 4', the damage of the optical windows 4, 4' can be prevented.
