IPC: C01B13/14
Filed: 1983-10-17
Abstract: PURPOSE:To produce easily handleable granular red mud easily forming tough crust on the surface, by granulating the water-containing cake of red mud with a granulator, adding the ash of a coal-fired fluidized bed boiler to the granulator when the growth of the granule is almost completed, and mixing the mixture.

The cake is mixed with about 15wt% ash of a coal-fired fluidized bed boiler, based on the supplied red mud, when the growth of the granule in the granulation stage is almost completed. A firm crust is formed on the surface of the granule by the combined effect of (i) the evaporation of water from the surface of the granule by the heat of the slaking reaction of CaO contained in the discharged ash, (ii) the hardening action caused by the adsorption of the red mud, (iii) the absorption of water from the surface of the red mud to the fine ash powder, and (iv) the coating effect of the ash to the granule, etc. Strong granules of red mud free from adhesivity can be produced by this process.

Abstract: PROBLEM TO BE SOLVED: To obtain an integrated circuit capacitor of high capacitance by using an inversion layer inside a lightly doped substrate as a plate paired electrode for a capacitor. SOLUTION: A depletion region 302 is formed around a memory node 224 peripheral besides neighboring to an N-separation band 204 by forming an inversion node capacitor 200 on a P-substrate 202. An inversion region 304 is formed inside the depletion region 302 near the memory node 224. The inversion region is connected to the N-separation band 204. Accordingly, an electric field between the memory node 224 and the paired electrode of the inversion region 304 is partially defined by a work function difference between the N- separation band 204 and an N<+> material inside the memory node 224. The N separation band 204 functions as a wiring connection to a common pared electrode of the inversion region 304 of the capacitor 200.
