IPC: G01N33/00
Filed: 1999-02-12
Abstract: PROBLEM TO BE SOLVED: To quickly perform an onsite measurement of dioxin concentration in waste gas and also automate the measurement by measuring the concentration of dioxin precursor coexisting in waste gas including dioxin and estimating the dioxin concentration therefrom. SOLUTION: The concentration of chlorobenzene Clx-Bz that is a precursor of dioxin in waste gas is measured by a Clx-Bz measuring device. The Clx-Bz to be measured is preliminarily selected from Cl3-, Cl4-, Cl5-and the like. The oxygen concentration in waste gas is separately measured by an oxygen concentration measuring device. Each of the resulting concentration data is transmitted to a data converter to convert the Clx-Bz concentration to a concentration based on oxygen concentration 12% (μg/Nm3O2=12%, unit). The dioxin concentration is calculated from the converted concentration by use of a preset Clx-Bz/ dioxin conversion multiple regression expression, and the result is displayed and recorded in a recorder.

IPC: H01Q19/13
Filed: 1988-02-19
Abstract: PURPOSE:To cause the quantity of an unnecessary radiating field to be small and to cause the distortion of the radiating pattern of a reflection mirror antenna to be small by mounting a cylinder-shaped channel in the outer circumference of a reflecting part. CONSTITUTION:An electromagnetic wave to be propagated in a circular waveguide is reflected by a reflecting part 5 and radiated in a front surface direction (central shaft direction) 7 of a primary radiator. For the reflecting part 5, a matching part 8 is provided to keep V.S.W.R. to be satisfactory and a cylinder-shaped channel 9 is provided to suppress the turning of a wall surface current in the outer circumference of the reflecting part. When the depth of the channel 9 is caused to be the 1/4 degree of a free space wavelength and the width of the channel is caused to be the 1/15 degree of the wavelength, the impedance of a surface goes to be extremely large and a current to flow from the inner wall of the reflecting part to an outer wall goes to be small. Thus, the quantity of the unnecessary radiating field, which goes from the aperture of the reflecting part 5 to a rear direction, can be suppressed to be small and the distortion of the radiating pattern can be made small.
