Title: Treatment of soil polluted with hexa-valent chromium
Inventor: WATANABE NORIMOTO
IPC: B09C1/08
Filed: 1996-09-12
Abstract: PROBLEM TO BE SOLVED: To detoxicate soil polluted with hexa-valent chromium in situ by bringing the soil polluted with hexa-valent chromium into contact with polyphenol and further with phosphoric acid or phosphates. SOLUTION: Soil polluted with hexa-valent chromium is contacted with polyphenol. Any polyphenol may be unlimitedly used and for example, catechol, resorcin, etc., are used. The resultant soil is further brought into contact with phosphoric acid or phosphates. Consequently, hexa-valent chromium is reduced to trivalent chromium and converted into chromic phosphate which has a low solubility in water. As long as the phosphoric acid and phosphates have solubility in water, any phosphoric acid and phosphates may be unlimitedly used and for example, orthophosphoric acid is used.  To determine the amounts of polyphenol, phosphoric acid, and phosphates, the content of hexa-valent chromium in the soil is previously determined and it is preferable to use about 0.1g or more of polyphenol based on the total organic carbon per 1g of hexa-valent chromium, about 2g or more of phosphoric acid and phosphates based on phosphate ion. As a result, the soil can be detoxicated in situ.

Abstract: PURPOSE:To distinctly decide a boundary and a corner part by detecting two values of rho, theta to make distribution large from a polar coordinate curve group obtained by Hough transformation from the data of an edge candidate point. CONSTITUTION:The curve group of Hough locus lines HG is obtained for all the edge candidate points (xi, yi) and (xj, yj) correspondingly to the boundaries B1, B2. When the coordinates (rho1, theta1) of the point where the most Hough locus lines HG of the group intersect each other on a rho-theta plane is found, one Hough locus line is specified, and when this line is reverse-mapped on x-y coordinates, one virtual boundary line E1 corresponding to the boundary B1 is obtained. Similarly, when the point (rho2, theta2) is found, the virtual boundary line E2 corresponding to the boundary B2 is obtained. By obtaining the intersection point K0 of the lines E1, E2 by using an ordinary intersection point calculating formula, the corner part C of the boundaries B1, B2 can be detected. Thus, the boundary between an worked area and an unworked area and the corner part can be discriminated distinctly so that automatic steering control can be executed exactly.

Filed: 1988-10-21
Abstract: PURPOSE:To eliminate the necessity of offset voltage adjustment with a simple circuit configuration by respectively providing peak hold circuits which hold peaks of outputs of output circuits between the output circuits and a subtractor which subtracts the outputs. CONSTITUTION:A photodetector element 20 divides reflected light from a medium into plural parts. Output circuits 21 respectively convert the divided outputs of the element 20 into electric signals. Envelopes are detected from reflected light pulses outputted from the circuits 21 at peak holders 24 and subtracted by means of a subtractor 22. Since the peaks of the reflected light pulses are held by the holders 24, the amplitude of the output of the subtractor 22 is constant irrespective of the duty ratio of the reflected light pulses. A gain switching amplifier 23 amplifiers the output of the subtractor 22 with different gains between the reading time and writing time. Therefore, the writing-time servo gain can be maintained constantly when gain switching is performed.

Abstract: PROBLEM TO BE SOLVED: To absorb excessive ions in a mesh-like electrode and to perform uniform charge neutralization by forwardly blowing off through air blasting positive and negative ions generated by a discharge electrode and by impinging the ions to an object subjected to charge neutralization through the mesh-like electrode. SOLUTION: Positive and negative ions generated by a discharge electrode 2 pass through meshes of a mesh-like electrode 4 by air blasting of a fan 5. Although a part of ions are absorbed by the electrode that is grounded, stable positive and negative ions pass though the meshes, are blown to an object 6 subjected to charge neutralization (charged body) with air, drawn by a heteropolar potential of the diselectrified object 6, and diselectrifies the object 6. After passed through the mesh-like electrode 4, a part of ions floating between the diselectrified object 6 are also absorbed by the electrode 4. The positive and negative ions affecting the charge neutralization from the object 6 subjected to charge neutralization are naturally brought into balance between the charges of the diselectrified object 6 itself.  Accordingly, charge neutralization is performed uniformly without inverse electrification.
