Abstract: PROBLEM TO BE SOLVED: To provide an image radar device capable of ensuring resolution in a cross-range direction and obtaining a high resolution image regardless of the distance to a target. SOLUTION: Reception beam data which a receiver 8 outputs is split in time axis with a distance detector in a two-dimensional imaging processor 10, and a distance R to a target is detected. The output frequency for obtaining desired resolution in cross-range direction according to the distance R is calculated with a frequency determination part, which is directed to a frequency controller 6. The frequency controller 6 controls an exciter 5 so as to output the directed frequency. The reception beam data by transmission signal output by the exciter 5 is split in time axis, the distance R is detected and reception power intensity is detected by a reception intensity detector. The distance R and the reception power intensity are produced as image information in an image information producing part.  The reception intensity is changed to brilliancy and displayed on image based on the produced image information.

Thereby, the adsorption of oxygen to the surface of a catalyst is blocked to prevent the decrease in catalytic activity caused by adsorption oxygen. As the organic polymer to be used, a fully fluorinated ionomer is desirable, and a fluororesin having carboxyl group or sulfo group (sulfone group) can be used. As the oxide to be used, an oxide containing monovalent copper, preferably Cu2 O, is used.

Filed: 1984-02-15
Abstract: PURPOSE:To prevent any cuts on the display screen which might occur due to thermal expansion by installing elastic positioning means between the display means and at least one of the electrode means for controlling electron beams. CONSTITUTION:Cylindrical positioning members 42 for positioning the display screen 41 of a display means and an electrode structure in a given positional relationship, are installed outside the display screen 41. In order to prevent the display screen 41 from touching an accelerating electrode during assembly, a coil-like spring 43 is attached around each cylindrical positioning member 42. The electrode structure and the display screen 41 are positioned in a special positional relationship by means of cylindrical positioning members 44 attached to a frame. Therefore the display screen 41 and the electrode structure are held with a given space provided between them during metal sealing. But, in the following process where the case is evacuated until a high level vacuum is produced, the space maintained by the coil-like springs 43 is compressed by atmospheric pressure thereby applying pressure to the convex area of the anode plate. Therefore this image display device can resist atmospheric pressure.

CONSTITUTION:The spent liquor combustion boiler 1 operates such that: the spent liquor L in  rough particle form is sprayed and adhered to opposing wall sections of the boiler 1 by use of  oscillators 2 which are arranged on both sides of the boiler in opposite relationship with each  other; the adhered spent liquor is dried by the radiation of heat in a furnace of the boiler to  make itself a porous solid component (char) which comes off one by one from the wall sections of the boiler 1 and falls down on the bottom of the furnace to produce a char bed; and  the char bed is burned by the supply of primary and secondary airs A1 and A2. In this case,  the primary and secondary airs A1 and A2 are prepared in such a manner that air passing through an air-preheater 30 is heated additionally to about 250 deg.C at a steam type air heater 31  through heat exchange with overheated steam S supplied from an overheated steam pipe 32  and is supplied into the furnace. Consequently, the reducing action within the char bed and the  combustion efficiency of the char by the boiler are increased.
