Abstract: PROBLEM TO BE SOLVED: To eliminate the need for after-treatments in a method with resistance to noise by using the spatial relative coordinate information of particle images, performing the coordination of each tracer particle between a plurality of temporally continuous images through the user of a predetermined expression, and obtaining an optimal value. SOLUTION: Particles in proximity to a particle P0 which is a standard for coordination are symbolized by P1 to Pi in increasing order of distance, and the centroidal coordinates of four particles Pa to Pd among particles satisfying the conditions of an expression among (i) pieces of particles are used for coordination information. In the expression, an integer of (a-d):(1-i), a≠b≠c≠d, an integer of (l-o):(1-j), i≠m≠n≠o, a function minG indicates the minimum element of a set G, |arrow| indicates a vector. Similarly, particles in proximity to a particle Q0 for evaluating the degree of coordination to the particle P0 are symbolized by Q1 to Qj in increasing order of distance, and the centroidal coordinates of four particles Q1 to Qo among particles satisfying the conditions of the expression among (j) pieces of particles are used for coordination information. Error values ER on all the particles in an analytic space are calculated by the expression, and a particle Qo with the minimum calculated error value is determined as the particle corresponding to the particle P0 .

Abstract: PURPOSE:To enhance the detecting speed without sacrifice of detection accuracy by preparing an ideal detection waveform for a part marked to be detected, performing a correlative operation using the ideal detection waveform and then checking the validity using the extreme values of the correlational function and the positions thereof. CONSTITUTION:A groove only one side is noticed for the marks matching two grooves to be detected, and an ideal detection waveform 102 is formed based on a design value and detecting conditions. A correlative operation is then performed with respect to a detection mark waveform 101 using the ideal detection waveform 102 thus obtaining a correlative function 103. The distance 105 between two extreme values 104 is then calculated for the correlative function 103. It is compared with the design value of distance between the lines of marks to be detected and the detection results are checked. If the results are valid, the intermediate point 106 of the distance between two extreme values is calculated as the central position of mark thus enhancing the detection accuracy and likelihood.

Title: Abnormality diagnosing method of sensor group
Inventor: ONO TOSHIHIKO
IPC: G08C19/30
Filed: 1983-02-23
Abstract: PURPOSE:To enable online diagnosis of the abnormality in the sensor group installed in a plant with good accuracy by using a Kalman filter and vector angle method. CONSTITUTION:The state quantity by a Kalman filter is predicted and estimated from a sensor signal 23 and the dynamic model of a plant. A likelihood ratio is calculated from the difference between the predicted value and an actual value, that is, a residual differential value. Said ratio is compared with a threshold value to which the likelihood ratio is given preliminarily, and the generation of abnormality is decided when said value is larger than the threshold value. When the abnormality is decided, the determination of an abnormal sensor and the calculation of the fluctuating rate are performed by a vector angle method. In other words, the abnormal sensor is located and the result thereof is displayed. The abnormality in the sensor group installed in the plant is thus diagnosed online with good accuracy.

Filed: 1990-02-08
Abstract: PURPOSE:To constitute this cleaner so that bugs such as ticks, caught by a dust collector can be allowed to perish by coupling thermally the dust collector and a motor-driven air blower by a heat pipe. CONSTITUTION:In a motor-driven air blower main body 1, the dust collector 3 connected to a suction implement 2 is provided, and in its rear, a motor-driven air blower 4 is provided. Also, the dust collector 3 is connected to a motor part being a heating member of the motor-driven air blower 3 by a heat pipe 5. When the motor-driven air blower 4 rotates, an air current in which dust and bugs such as ticks are mixed is sucked into the dust collector 3 from the suction implement 2 and caught, and cleaned air is exhausted from an exhausting port 6. Since the efficiency of the motor-driven air blower 4 is about 40%, for instance, in the case the power of 600W is inputted, 360W becomes heat energy and is consumed, and this heat energy is led to the dust collector 3 by the heat pipe 5 and the dust collector 3 is heated. Accordingly, by holding the temperature of the inside of the dust collector 3 at high and also, holding a dry state, the bugs such as ticks caught in the dust collector 3 can be allowed to perish.
