Title: Decomposition of halogenated hydrocarbons
Inventor: OGURA KOTARO
IPC: B01D53/34
Filed: 1990-01-24
Abstract: PURPOSE:To make halogenated hydrocarbons such as CFCs harmless efficiently and accurately in a mild state by a method wherein the halogenated hydrocarbons are irradiated with light energy in the presence of oxygen to react with radical scavenger. CONSTITUTION:The halogenated hydrocarbons contg. CFCs, chloroform and carbon tetrachloride, e.g. 1,1,2-trichloro-1,2,2-trifluoroethane (flon 113) and trichloromonofluoromethane (flon 11), are irradiated with light energy in the presence of oxygen to react with a radical scavenger such as zinc, iron and Devarda's alloy. By this method, the radical rebinding can be prevented accurately and the halogenated hydrocarbons can be efficiently decomposed in its entirety. The aforesaid reaction is conducted in a closed circulation or a flow system, preferably at a temp. of 60-100 deg.C.

Abstract: PURPOSE:To always keep the stability of a servo circuit high by providing an amplifying means whose gain is controlled in response to the amplitude of a tracking error signal into a tracking servo loop, and setting previously the gain of said amplifying means when the tracking servo loop is opened. CONSTITUTION:An amplifying circuit 30 detects the amplitude of a tracking error signal and then varies the amplification degree of the error signal in accordance with the result of amplitude detection.

IPC: C21C5/40
Filed: 1992-01-30
Abstract: PURPOSE:To improve the recovering efficiency of converter gas by opening only a recovering valve in the case oxygen concn. at the furnace top part is a fixed value or below and further, turning a three-way valve to the recovering side in the case the oxygen concn. at downstream side of an induced draft fan is a fixed value or below. CONSTITUTION:The gas incorporating CO produced in a converter 1 is sucked by the induced draft fan 4 through a cooler 2 and a dust collector 3, and discharged to a flare stack 8 through the three way valve 5 and the recovering valve 6 or recovered in a holder 7. In the above-mentioned recovering method of the converter gas, when the oxygen concn. in a furnace top oxygen density meter A1 becomes the fixed value L2 of below in the condition of the converter gas recovering condition except the fixed value L1 or below of the oxygen concn. in the induced draft fan downstream side oxygen concentration meter A2, the open command is issued only to the recovering valve 6. Therefore, as soon as all converter gas recovering condition incorporating the oxygen concn. L1 or below is satisfied, the three-way valve 5 is changed over from the flare stack to the recovering side and the converter gas is recovered in the holder 7. Thus, dispersion of gas while driving the recovering valve 5 to open is prevented, and the recovering efficiency of the converter gas is improved.

Title: Priority order discriminating device
Inventor: TAMURA ICHIRO
IPC: G06F13/14
Filed: 1989-01-25
Abstract: PURPOSE:To decide a priority order code signal in its coded state by outputting a code signal of a lower rank digit as a level O when an input code signal is kept at a level I together with an output signal kept at a level O respectively. CONSTITUTION:Each priority order signal (code signal of plural digits) is inputted to each gate circuit. The gate circuit compares an input code signal with an output signal fed back from a digit-based OR circuit where an OR is secured between the code signals of the same digit as a relevant digit. When the input code signal is kept at a level I together with the output signal kept at a level O respectively, a code signal of the priority order signal having a digit lower than the relevant digit is outputted as a level O. Thus the priority order is discriminated for a priority order code signal in its coded state. Thus an encoder, a decoder, and their peripheral circuits like the wirings, etc., can be omitted.
