Title: Production of granular silicon and apparatus therefor
Inventor: OGI KATSUMI
IPC: C01B33/02
Filed: 1988-02-12
Abstract: PURPOSE:To obtain a high-purity granular polycrystalline silicon in high yield, by contacting fluidized silicon particles with a raw material gas such as silane gas under specific condition, thereby effecting the growth of the particle by the deposition of silicon produced by the H2 reduction or thermal decomposition of the raw material gas on the surface of the particle. CONSTITUTION:Silicon particles classified e.g., to 60-150 mesh are placed on a dispersion plate 22 at the bottom of a reaction vessel 10. A fluidizing gas composed of H2 or an inert gas such as N2, Ar or He is introduced into the reactor through a fluidizing gas inlet pipe 21 and, at the same time, the heating zone 11 is heated with a furnace 13 to heat and fluidize the silicon particles at a temperature above the thermal decomposition temperature of the raw material gas consisting of SiH4, SiHCl3, Si2Cl6, Si3Cl8, Si4Cl10, etc., or their mixture (e.g., >=500 deg.C). The above raw material gas is introduced through a feeding pipe 31 into an unheated zone 12 having a wall surface temperature controlled to a temperature below the thermal decomposition temperature of the above raw material gas (i.e. <=450 deg.C) with a cooling means 14 and is made to contact with the above fluidized particles to effect the H2 reduction or thermal decomposition of the raw material and the deposition of the formed silicon on the surface of the particle. The objective silicon can be produced by this process in high yield while preventing the deposition of silicon on the wall surface 12.

Filed: 1989-02-08
Abstract: PURPOSE:To speed up the operation of a system including a low-speed access memory by replacing the operation of the low-speed access memory with the operation of a high-speed access memory when a processor is operated at high speed. CONSTITUTION:First, a clock switching control circuit 6 supplies a clock signals CLK2, which are obtained by internally dividing a system clock signal CLKS into two, as an operating clock signal CK to a microprocessor 1.

Abstract: PURPOSE:To efficiently execute classification of small separated particle diameters by increasing the diameter of a guide plate to increase the diameter of a feed groove and providing an air inflow means for dispersing a powder material by swirling flow to the outside circumference in the upper part of a classifying chamber. CONSTITUTION:The diameter of the guide plate 15 is made larger than the diameter of the conventional device, by which the diameter of the annular feed groove 11 is increased and the distance up to a fine powder discharge pipe 7 can be increased; therefore, the intrusion of coarse powder into the fine powder discharged from the fine powder discharge pipe 7 is prevented and the average particle size of the separated fine powder is reduced. The powder material which is concentrated by centrifugal force on the inside wall of a guide cylinder 10 and is admitted from the annular feed groove 11 into the classifying chamber 4 is dispersed by the air admitted from an air inflow port 12 in the upper part of the classifying chamber 4. In addition, the material is swirled and dropped into the lower part of the classifying chamber 4 by accelerating the swirling power thereof. The swirling flow is further accelerated by the air flowing in from an air inflow port 8 by which the material is classified to the coarse powder and the fine powder.
