Inventor: YOSHIDA KUNIKATSU
IPC: B01D53/50
Filed: 1995-01-31
Abstract: PURPOSE: To improve adsorption performance per unit liquid volume in a method in which air is fed into an absorbing solution which has absorbed sulfur oxide in waste gas to form gypsum and is being recovered, by jetting the absorbing solution in the direction almost apposite to the flow direction of the waste gas before spraying it in the same direction as that of the waste gas. CONSTITUTION: Sulfur oxide-contg. warm waste gases 20a, 20b are cooled by heat exchangers 15a, 15b to be turned into cool ward gases 21a, 21b, which are fed into inlet ducts 2a, 2b. At the outlets of the inlet ducts 2a, 2b, that is, at waste gas inlets 16a, 16b of an adsorber 1, an adsorbing solution 19 is sprayed from nozzles 13a, 13b, and the jet streams of waste gas are agitated by an impact space 18 in the adsorber 1 with each other to absorb sulfur oxide. After that, the gas flow enters outlet ducts 3a, 3b from purified gas outlets 17a, 17b, and after mist is removed by mist eliminators 14a, 14b installed there, it is released in the air as purified gases 22a, 22b via heat exchangers 15a, 15b.

Title: Image forming device
Inventor: HANEDA SATORU
IPC: G03G15/01
Filed: 1988-01-27
Abstract: PURPOSE:To prevent deterioration in image quality by providing a means discharging to a photosensitive body with electric charges of polarity identical to the potential of the image part of the photosensitive body, and a means uniformly projecting light of wavelength transmitting toner on the photosensitive body almost at the same time as discharging, after a developing step and before a transfer step. CONSTITUTION:A discharger/exposer 10 is provided between a developing unit 4 and a transfer electrode 5. The light source 14 of the discharger/exposer 10 uniformly projects light on the photoconductive layer surface of the photosensitive drum 1, and simultaneously an electrode 12 discharges negative electric charges, whereby negative electric charges on the photosensitive body in a positive toner adhering part disappear to lower the potential. In case of electric charges in a part below the toner, it is also exposed when wavelength transmitting the toner is employed as that of light from the light source 14. Thus, toner scattering is reduced to prevent deterioration in image quality.

IPC: H01Q19/12
Filed: 1995-02-02
Abstract: PURPOSE: To suppress the deterioration in a side lobe characteristic without a large sized torus mirror surface by deciding an X coordinate between a lower end and an upper end of a torus mirror surface based on an equi-phase line of a mirror surface edge aperture electric field distribution at both left and right ends of the torus mirror surface.

Thus, the method of suppressing the deterioration in the side lobe characteristic is taken without increasing the torus mirror surface.  An X-axis is set in parallel with a rotation symmetrical axis 1 of the torus mirror surface 2, let the X coordinate of the lower end and the upper end of the torus mirror surface be respectively X1 , X2 , then an angle Σ(x) between the mirror surface edge direction of the torus mirror surface 2 and the rotation symmetrical axis 1 at an X (X1 <X<X2 ) is specified as Σ(X)=± ξ(x)+σ}, then the function ξ(x) is decided from an equi-phase line of an aperture electric field distribution of the torus mirror surface 2.

After that, heating time is set at the time scale prescribed on the time scale table with a pointer 5, which is vertically shifted with a string 15 by turning a pulley 14. When an operating button 10 is depressed, a microcomputer control circuit 13 puts a heating device 19 in operation with the high-frequency output of 600W, which is judged from the signal issued by a scale position detector 18 to detect the turning angle of a thumb shaft 17 resulted from the turning of the pulley 14, and at the same time allows a time switch 20 to operate for a set period of time.
