Title: Method and device for energy subtraction of radiograph
Inventor: NAKAJIMA NOBUYOSHI
IPC: H04N5/325
Filed: 1989-09-22
Abstract: PURPOSE:To obtain a subtraction image of high picture quality by securing such a constitution where plural picture signals correct the MTF (modulation transfer function) difference of their own radiation images respectively and then carries out the subtraction processes. CONSTITUTION:When two picture signals SO1 and SO2 which perform the subtraction processes are stored in an internal memory of an image process display device 30, the 2nd picture signal SO2 is read out and the MTF of an X-ray image of the signal SO2 is corrected. In this case, it is also practical to correct the MTF of an X-ray image of the 1st picture signal SO1 so as to secure the coincidence with the MTF of the X-ray image of the signal SO2. Then the subtraction operations of the radiograph are carried out based on the corrected picture signals. As a result, a high frequency component of an original image never remains in a subtraction image as a false image and the picture quality of the subtraction image is improved.

Title: Air-fuel ratio control device for internal combustion engine
Inventor: OGAWA MASARU
IPC: F02D41/14
Filed: 1992-08-24
Abstract: PURPOSE:To improve the emission characteristics of exhaust gas by adjusting an air-fuel ratio of air-fuel mixture constantly to a desired value even when an exhaust gas passage is switched. CONSTITUTION:In feedback control of an air-fuel ratio, an output value from an LAF sensor is read and when it is decided that an engine is in a fundamental mode, a target air-fuel ratio factor KCMD is determined at S21-S23 according to whether fuel is under cut. When a BPV is OFF, the KCMD is not corrected and an air-fuel ratio is set to a corrected target value KAMDM at S24 and S25. When the BPV is ON, KCMD is calculated by effecting correction and limit check of the KCMDM at S24-S27. Based on the calculated KCMDM value, feedback control of the air-fuel ratio is executed.

Title: Method and apparatus for removing phosphorus in waste water
Inventor: TAKECHI TATSUO
IPC: C02F3/30
Filed: 1998-09-03
Abstract: PROBLEM TO BE SOLVED: To effectively and inexpensively prevent the deterioration of phosphorus removing performance while compensating the shortage of the organic material concentration in the waste water and effectively utilizing a produced organic material by crushing or grinding at least a part of deposits in a sedimentation basin for the waste water to be treated and supplying them to an anaerobic vessel. SOLUTION: The waste water 1 is fed to the anaerobic vessel 3 and an aerobic vessel 4 through solid-liquid separation in an initial sedimentation basin 2 and is separated into treated water 7 and activated sludge in a final sedimentation basin 6. The deposits 9 of the initial sedimentation basin 2 are crushed or ground by a crushing or grinding device 10 and sent to the anaerobic vessel 3 directly or through a flow-out water passage or the like. In the anaerobic vessel 3, phosphate ion accumulated in the activated sludge cells is released in the waste water by utilizing the organic material originating from the initial sedimentation basin deposit 9. In the aerobic vessel 4, the activated sludge assimilates the phosphate ion in the waste water in the activated sludge cells to carry out the oxidation decomposition and the removal of the organic material. Thus the method is effectively and rapidly utilized for the phosphorus releasing and the phosphorus assimilation reaction.
