Title: Treatment of gas liquor
Inventor: HASHIMOTO TAKAO
IPC: C02F9/00
Filed: 1982-03-31
Abstract: PURPOSE:To remove pollutants from a condensed gas liquor formed by cooling coke oven gas, by treating said gas liquor with active sludge, spreading the treated waste water onto piled-up coal, and then thermally decomposing the coal in a coke oven. CONSTITUTION:A gas liquor 2 formed from condensed water in gas by cooling the gas formed in a coke oven 1 is treated 4 with activated sludge, and the waste water after being treated is added as yard sprinkling water to a thickener 7 for a coal yard to precipitate the part of solid matter among residual pollutants in the waste water by the thickener 7. A supernatant liquid in the thickener 7 is pressurized by a pump 8 and spread onto piled-up coal through sprinkling arrangements 9 provided at a coal yard 10. Consequently, the most of the residual soluble pollutants are adsorbed onto the coal, the part of water is evaporated into the atmospheric air, and the residual liquid is returned into the thickener 7 again.

Title: Production of 5-aminoquinolonecarboxylic acid derivative
Inventor: NAKANO JUNJI
IPC: A61P31/04
Filed: 1989-03-07
Abstract: PURPOSE:To readily produce the subject compounds useful as an intermediate for synthesis of an antibacterial agent in a high yield by using a tetrafluorobenzoic acid derivative as the starting raw material, carrying out reactions in order for formation of an aminoacrylic acid derivative and subsequently cyclizing the resultant derivative. CONSTITUTION:A compound of formula I (X1-X4 are halogen; R1 and R2 are lower alkyl, arylalkyl or acyl) is condensed with a malonic acid ester and the resultant condensate is subsequently deesterified to obtain a benzoylacetic acid derivative of formula II (R3 is lower alkyl). The resultant benzoylacetic acid derivative is then reacted with acetic anhydride and an orthoformic acid ester or a dimethylformamide dialkyl acetal and subsequently with an amine of formula R4-NH2 (R4 is lower alkyl, cycloalkyl, phenyl, etc.) to prepare an aminoacrylic acid derivative of formula III. The obtained aminoacrylic acid derivative is then subjected to a cyclization reaction in the presence of a base (e.g. sodium hydride) in a solvent such as ethanol at 0-180 deg.C, thus obtaining the objective compound of formula IV.

IPC: G06F9/06
Filed: 1990-03-07
Abstract: PURPOSE:To prevent a batch area from being broken due to the input miss of batch data by checking the collation of a storage address based upon batch management information and the idle area information of a patch area. CONSTITUTION:A batch processor 2 reads out batch data from an input device 1. An address collating part 21 compares and collates addresses respectively included in the inputted batch management information and the idle area information 32. When both the addresses are different from each other as the result of collation, the patch data are not stored in the batch area. When the address coincide with each other, a batch processing part 22 stores the batch data into a batch area 31 of a filing device 3. The leading address of the idle area included in the information 32 and the length information of the idle area are updated by the data obtained after storing the batch data in accordance with the stored result. Thereby, the batch area can be prevented from being broke by the overlap of stored programs due to the discrepancy of addresses.
