Abstract: PROBLEM TO BE SOLVED: To obtain a low-cost motor controller having a simplified structure. SOLUTION: A microcomputer 8 has, for instance, a CPU, a RAM and a ROM. Relations between the values of sine signals and cosine signals and rotation positions θ of a rotor are stored in the ROM, in the form of a table. The microcomputer 8 samples the sine signals outputted from a sine output winding 63 and the cosine signals outputted from a cosine winding 64 at constant timings and the instantaneous values of the sine signals and the cosine signals which are obtained by the sampling are subjected to A/D conversion to obtain the instantaneous value data of the sine signals and the cosine signals. The instantaneous value data of the sine signals and the cosine signals are given to the table stored in the ROM. A rotation positions θ of the rotor corresponding to the instantaneous values of the sine signals, and the cosine signals are read out of the table.

Abstract: PURPOSE:To detect the wear quantity of a pin type sample with time highly accurately by installing a noncontact type displacement gauge at a pin sample holder part which moves following up the wear of the pin type sample, and measuring the relative displacement between the pin sample holder part and a disk type sample. CONSTITUTION:The pin type sample 4 is pressed with a constant load against the disk type sample 3 placed on a sample table 2 which rotates on a testing device base 1 through a bearing 7. Then the noncontact type displacement gauge 5 is fixed to the sample holder 6 which moves following up the wear of the sample 4 and the distance to the slide track of the sample 3 is measured to measure the wear of the sample 4 in a pin disk type wear test with high accuracy. Namely, the difference between the distance from the displacement gauge 5 to the sample in sliding motion and the distance before the sliding is measured as wear. Further, the displacement gauge 5 is fixed to the holder 6, so the displacement gauge 5 operates following up the waving of a disk and variation in the heat expansion of the whole device, so the waving of the disk and the heat expansion of the whole device can be ignored.

Title: Detecting apparatus for defect inside tube
Inventor: SAITO SHINICHI
IPC: G01N27/83
Filed: 1989-09-29
Abstract: PURPOSE:To enhance the detecting accuracy of defects inside a tube by providing a long yoke which is concentrically arranged with the tube, an annular permanent magnet which surrounds the yoke and is positioned in the vicinity of the inner surface of the tube and a plurality of detecting coils which are arranged along the circumferential direction of the tube. CONSTITUTION:A permanent magnet 6 surrounds a yoke 5 and has the same polarity on the same side. A plurality of detecting coils 7 are arranged along the circumferential direction of a tube 1. A main body having the permanent magnet and the coils is contained in a casing. When this apparatus passes the sound part in the tube 1, the tube 1 is magnetized with the magnet 6 at the approximately saturated magnetic flux density. A magnetic circuit is formed in the path from the outer surface part of a permanent magnet piece 61 through the tube 1 and the yoke 5 to the inner surface of the magnet 6. When the apparatus passes the defective part, the magnetic flux leaking from the defective part 1a is interlinked with the coils 7. Thus a magnetic circuit P is formed from the defective part 1a to the inner surface part of the magnet piece 61 through the coils 7 and the yoke 5. The amount of the change in leaking magnetic flux is proportional to the decreasing amount of the cross sectional area of the tube 1. Thus the depth of the defective part can be detected accurately.

IPC: H03M13/00
Filed: 1991-10-04
Abstract: PURPOSE:To shorten processing time with the circuit scale of the same degree by obtaining an error pattern in parallel to the derivation calculation of an error position through the use of a halfway value in the original substitution calculation of a Galois field to an error position polynominal. CONSTITUTION:The zero check circuit 110 of eight substitution blocks 101, 102,...108, a nine inputs exclusive OR circuit 120, an eight inputs exclusive OR circuit 130, an error position derivation block 140 and an error pattern derivation block 150 are provided. The substitution block circuits and the addition circuit (XOR 9) 120 derive the error position.
