Title: Method of desulfurization
Inventor: FUJII MAMORU
IPC: B01D53/50
Filed: 1986-11-15
Abstract: PURPOSE:To contrive to obtain high desulfurizing rate as well as to decrease the amount of limestone to be used, by desulfurizing exhaust gas by reacting ashes containing unreacted lime, discharged from a fluidized-bed boiler or the like, on the exhaust gas which is discharged from the fluidized-bed boiler or the like. CONSTITUTION:Combustion air is fed into a fluidized-bed boiler 1 by a forced draft fan 7 through a gas air heater 2, and combustion is started. At the same time of the starting of combustion, limestone is thrown into the fluidized-bed boiler 1. It is thermally decomposed into quicklime CaO, and part of SOx in combustion gas produced in the boiler 1 reacts on CaO to become CaSO4. Ashes after combustion of fuel, plaster, and unreacted lime are contained in the ashes produced in the fluidized-bed boiler 1, as well as in the combustible exhaust gas caught by a gas air heater 2 and by a dust collector 3. The ashes containing the unreacted lime is introduced into a dry type desulfurizer 4. The combustion exhaust gas again reacts on the lime in the dry type desulfurizer 4 and SOx is removed from the exhaust gas, becoming CaSO4. That is, the desulfrizing rate can be increased by reutilizing limestone thrown into the fluidized-bed boiler.

IPC: H01L21/304
Filed: 1993-10-05
Abstract: PURPOSE:To reduce the size of an automatic substrate processing unit being used while enhancing the processing effect by setting the maximum dimension of a cassette in the direction parallel with the main surface of a substrate smaller than the outline dimension of the substrate in that direction.

Since a downsized substrate holding cassette 20 is employed, the capacity of processing tank can be reduced.

Filed: 1994-11-07
Abstract: PURPOSE: To provide an illumination device for a liquid crystal display panel constituted so that light from a light transmission plate is prevented from leaking without using a bulky light shielding member, the number of parts and the number of working processes are reduced and a space is saved.

The light entering in this way is multiply reflected and diffused by the surfaces 3b and 3c of the plate 3. Besides, it is uniformly diffused extending over the whole area of the plate 3. Since the light diffused in this way is totally reflected on a reflecting film 6 when it abuts on the side surface 3a of the plate 3, it is not leaked to the outside. On the other hand, the diffused light is uniformly emitted from the surface 3b so as to illuminate the liquid crystal display plate(LCD) 1.
