IPC: B09B3/00
Filed: 2001-11-20
Abstract: PROBLEM TO BE SOLVED: To certainly perform bio-augmentation by suppressing the propagation of obstractive bacteria. SOLUTION: In the method for decomposing and removing a pollutant by microorganisms, first, a solution containing transition metal ions having low valence is added to polluted soil mixed with dioxins. Next, an aqueous hydrogen peroxide solution is further added to this polluted soil. Whereupon, the solution containing transition metal ions having low valence and the aqueous hydrogen peroxide solution generate Fenton's reaction to form hydroxyl radicals. These hydroxyl radicals subject dioxins getting mixed in polluted soil to oxidative decomposition by the strong oxidizing force thereof to convert them to easily decomposable substances and also dissociate dioxins adhering to the surfaces of particles of polluted soil from those particles. Further, the hydroxyl radicals also preliminarily sterilize obstractive bacteria living in polluted soil by the strong oxidizing force thereof.  Next, predetermined selected bacteria are added to the polluted soil of this state to keep an environment fitted to the living environment of microorganisms.

Title: Information reproducing system
Inventor: TATSUTA SEIJI
IPC: G06K19/00
Filed: 2001-12-11
Abstract: PROBLEM TO BE SOLVED: To correctly reproduce information by reading a densely recorded code pattern. SOLUTION: From among a plurality of blocks, a block to which a block receiving the small influence of optical distortion is selected and read. When a code is recorded by double heights, for example, data in a processing object block 82 is read in the order 1 to 9. Since the block of 1 is closer to the end of a frame 60 even though the same data is recorded in the block of 1 and the block of 2, the probability of the occurrence of a read errors due to optical distortion is high. Then, by reading the data in the block of 2 once more and overwriting it after that, more precise data can be obtained.
