IPC: C21C1/02
Filed: 1986-09-11
Abstract: PURPOSE:To prevent molten iron at high reaction efficiency, by blowing treating agent into the molten iron continuously flowing in a trough from plural blowing lances and setting up suitably the upper limit quantity of the treating agent blown from each lance and an interval of lance. CONSTITUTION:In a casting floor of blast furnace, the treating agent, such as desiliconizing agent, desulfurizing agent, dephosphorizing agent, etc., is blown into the molten iron 2 continuously flowing in the trough from the plural blowing lances 1a, 1b arranged above the molten iron 2 or as submerging into the molten iron 2 together with carrier gas. In the pretreating method for molten iron at the casting floor in the blast furnace having the above constitution, the upper limit quantity of treating agent from the one piece of blowing lance 1a is to decide to 25kg/t. Further, in case of needing more blowing quantity than the above, plural pieces of lances 1a, 1b are used and the interval between each lance is blown under condition of keeping from >=1.0m. In this way, dispersion of the treating agent blown is improved and the treating efficiency is improved by relaxing the adverse effect caused by interference between the lance.

Abstract: PURPOSE:To form a fine pattern by means of no mask, by mounting a material to be etched under an atmosphere of radical species and raising a temperature of only a definite part of the material to be etched and increasing an etching speed of the definite part whose temperature has been raised. CONSTITUTION:A substrate 8 is mounted on a sample board 7 and the first and second chambers 1 and 5 are exhausted to be highly vacuumized. While Cl2 gase is supplied from a gas introduction port 3, Cl* is generated in the chamber 1 by providing microwaves from a waveguide 2 and forming a fixed magnetic field by means of electromagnets 4. The Cl* generated is introduced to the sample board 7 and so the substrate 8 is made to be under an atmosphere of Cl*. A definite part of the substrate 8 is irradiated with laser from a laser oscillator 10. As a result, a line-and-space part of 4-5mum in width and of 5000Angstrom  in groove depth is formed on the substrate 8. A temperature of the part irradiated with laser is locally raised and so an etching process is promoted. Hence, a fine pattern is formed by means of no mask.

Abstract: PROBLEM TO BE SOLVED: To provide a void filler reducing friction and capable of improving filling workability by using an inorganic/organic composite foam body having the prescribed density and recovered to the prescribed ratio or above after its cross sectional area is compressed to the prescribed ratio as the void filler. SOLUTION: An inorganic/organic composite foam body, which has the density of 40 kg/cm3 or above and is recovered to 50% or above of the cross sectional area before compression after it is compressed to 25% of the cross sectional area and external force is removed, is used as a void filler 3 of tubular voids 2, of an extrusion- molded cement board 1. A foam body foamed with phosphoric acids and a urethane polymer having the NCD group are preferably used as the inorganic/organic composite foam body. The void filler 3 having the cross sectional area after recovery larger by 5% or above than the cross sectional area S of the void 2 is compressed into a rod shape of about 25% of the cross sectional area S and is quickly inserted into the void 2.  The cross sectional area of the void filler 3 is recovered after it is left as it is for several minutes, and the void filler 3 is closely stuck and filled in the void 2 with no gap. The cross sectional area of the void filler 3 is made smaller than the cross sectional area S for filling, thus the void filler 3 can be filled simply and efficiently with no friction.

Abstract: PURPOSE:To improve the yield of a light emitting device at the mesa etching time by selecting the photoconductive direction of a buried type smiconductor laser formed on a semiconductor substrate of (100) plane to an axis (010) or (001). CONSTITUTION:An n type InP 10, non-added GaInAsP active layer 11, a p type InP layer 12, a p<+> type GaInAsP layer 13 are sequentially epitaxially formed in liquid phase on an InP substrate 9 of (100) plane, and an SiO2 mask 14 of strip having a width of approx. 2mum is formed in (010) or (001) direction.
