Inventor: TAKAHASHI HIDEO
IPC: G06T7/00
Filed: 1996-05-23
Abstract: PROBLEM TO BE SOLVED: To perform a precise judgment regardless of the form of a defect candidate by providing a characteristic parameter extracting part for determining the actual maximum dimension of the defect candidate taken as a characteristic parameter by a prescribed processing algorithm. SOLUTION: A scope 10 is moved in a prescribed direction to take the image signal of the whole circumference of a bore inner wall surface, and a defect candidate is extracted after the image is binarized. In the same manner as judgment standard, actual maximum dimension of the defect candidate is determined. As this maximum dimension, non-corrected long edge length is taken when the diameter converted value is less than the long edge length/corrected short edge length, and the long edge length after distortion correction is taken when the diameter converted value is the long edge length/corrected short edge length or more, and its ratio is a prescribed value A or more. The diameter converted value is taken when the diameter converted value is the long edge length/corrected short edge length or more, and the ratio is less than the prescribed value A, and the long edge/short edge ratio is a prescribed value B or more. When the diameter converted value is the long edge length/corrected short edge length or more, the ratio is less than the prescribed value A, and the long edge/ short edge ratio is less than the prescribed value B, the short edge length after distortion correction is taken.

Title: Semiconductor memory
Inventor: KUME EIJI
IPC: G11C11/34
Filed: 1987-05-27
Abstract: PURPOSE:To reduce a difference of sense amplifier activating speeds between subblocks and to attain the stable operation of a memory by increasing the driving capacity of a driving circuit having large signal wiring resistance and reducing that of a driving circuit having small signal wiring resistance. CONSTITUTION:When a memory array MA1 having a far distance from a sense amplifier driving circuit is selected, i.e. when the resistance of signal wiring connecting the driving circuit to the subblocks is high, the number of driving transistors (TRs) in the driving circuit is increased and driving capacity is increased, so that the sense amplifier activating speed can be increased. When a memory array MAo having a near distance from sense amplifier driving circuit is selected, i.e., the resistance of signal wiring connecting the driving circuit to the subblocks is low, the number of driving TRs in the driving circuit is reduced and the sense amplifier activating speed is reduced. Consequently the sense amplifier activating speed of the subblock BLK00 can be made equal to that of the BLK10 the sensitivity of the sense amplifiers can be uniformed and the stable operation of the memory can be attained.

Abstract: PURPOSE:To suppress the generation of Barkhausen noises by providing at least >=2 conductor wires near a magneto-resistance effect (MR) element and impressing the synthesized magnetic field thereof in the easy axis direction of the MR element. CONSTITUTION:The two conductor wires 18a, 18b are disposed near the MR element 11 in a manner as to hold the MR element 11 therebetween and are so formed that the respective forming surfaces of the MR element 11 and the conductor wires 18a, 18b have the positional relations parallel with each other. A current j having the component perpendicular to the longitudinal direction of the MR element 11 is passed and the synthesized magnetic field H of the two conductor wires 18a, 18b is impressed in the easy axis direction of the MR film. The static magnetic energy by the diamagnetic field in the MR element 11 is lowered by the current magnetic field synthesized by the currents J1, J2 which flow in the two conductor wires 18a, 18b which are impressed in the easy axis direction of the MR film. The MR element 11 is, therefore, formed into the single magnetic domain structure having no magnetic walls. Since there is no movement of the magnetic wall, the Barkhausen noises are suppressed.

Title: Method and device for measuring current
Inventor: NISHIFUJI KATSUYUKI
IPC: G01R15/18
Filed: 1990-05-21
Abstract: PURPOSE:To measure a current value with high accuracy and high sensitivity by superimposing a voltage, which is guided and generated by a current to be measured, to an alternate current voltage, which always excites a magnetic sensor, and adding the voltage to the input side of the alternate current voltage or the coil of the sensor. CONSTITUTION:For an alternate current voltage E1 to be outputted from an alternate current oscillator 5, an alternate current flows through an adder 9, serial impedance 6 and terminal P to a coil 4 of a troidal core 3 constituting a magnetic sensor 2. Therefore, the alternate current voltage to be generated at the coil 4 is impressed to the input end P of a detector 7. Next, when a current Im to be measured flows to a conductor 1, magnetic flux corresponding to this current crosses the core 3 and corresponding to the strength fluctuation of a synthesized magnetic field generated in the core 3, amplitudes are fluctuated on the plus and minus sides of a voltage E. This amplitude fluctuation is detected 7 and voltage detection 7 is executed to the amplitude difference. Then, the difference is amplified 8 and an output voltage V corresponding to the current Im is obtained. By measuring this voltage V, the current value to be measured is read. On the other hand, the voltage V is negatively fed back to the adder 9 and applied to the coil 4 and while holding a closed loop in a balanced state, stable measurement is executed.

Title: Control of rear wheel steering gear
Inventor: TAKAHASHI AKIRA
IPC: B62D105/00
Filed: 1993-05-31
Abstract: PURPOSE:To justify rear wheel steering in the unstable case of the output signal of a yaw rate sensor by changing over modes to a mode in which yaw rate factor has large values in the same phase direction sequentially as time goes on and many steering wheel angle factors are in the inverse phase direction and a normal mode in the stable neutral time. CONSTITUTION:A mode in which a yaw rate factor Kgamma is about zero and a steering wheel angle factor Ktheta has few inverse phase directions and many same phase directions is provided immediately after the operation of a yaw rate sensor 44, and as time goes on, sequentially is changed over to a mode in which the yaw rate factor Kgamma has a large value in the same phase direction and the many handle angle factors Ktheta are in the reverse phase direction and the normal mode in the stable neutral time. In the most unstable case in the initial traveling, rear wheels are steered only according to the steering wheel angle theta and the factor Ktheta for example and erroneous actions caused by unstable yaw rate gamma is avoided even in immediate traveling of a vehicle. Also, the inverse phase steering angle and same phase yaw rate are strengthened in proportion to the increase of the stability of a neutral position of the output signal of the sensor for feedback control so that the rear wheels are steered to the stable side even against changes in he behavior of the vehicle.
