Title: Manufacture of shaft of magnetostrictive torque sensor
Inventor: SHIBATA YOSHIO
IPC: G01L3/10
Filed: 1989-05-18
Abstract: PURPOSE:To improve the mechanical strength, specially, fatigue strength by generating compressive strain in a stress converged part and tensile strain which is larger than strain at the time of yielding tension on the surface of a shaft body. CONSTITUTION:The stress converged part 2 where groove parts 3 and raised parts are formed alternately and spirally in the peripheral direction is formed on the shaft body 1. Then torsion torque as a mechanical load is applied to the shaft body 1 to generate the compressive stress in the stress converged part 2 and in such a state, the tensile strain which is larger than the strain at the time of yielding tension is generated uniformly in the shaft body 1 to generate strain corresponding to the difference between the tensile strain and compressive strain in the stress converged part 2 and tensile strain in other parts. Then the generation cause of the mechanical load and tensile strain is removed and compressive remaining stress corresponding to the tensile strain is generated in the surface of the shaft body 1. At such a time, the compressive remaining stress in the stress converged part 2 is smaller than those in other parts of the shaft body 1, and consequently magnetic anisotropy based upon the remaining stress is generated in the shaft body 1.

Title: Body position detector
Inventor: IGURA KOJI
IPC: G06T7/00
Filed: 1994-06-08
Abstract: PURPOSE:To shorten the operating time without lowering detecting accuracy by reducing an image before the detection of the body recognition and the position attitude of the image, recognizing an object body, detecting the position attitude, setting a local region on the object body, and detecting the body recognition and the position attitude for the local region set in the image before the reduction of the image. CONSTITUTION:The image is inputted from a two-dimensional camera 5 into an image processor 6 with standard picture elements. The inputted picture elements are reduced step by step. Preprocessing is performed with the reduced image, and the characteristic value is extracted. Then, model base matching is performed, and body recognition and position detection are performed. The body position/attitude data as the result of matching are used, the image is expanded to the image of standard resolution before the reduction and a local region is set. The preprocessing and matching of the image are performed for the local region again, and the detailed position detection of the object body is performed. The local region includes the characteristic value of the body in the standard image and the characteristic value of a model. Therefore, the same detecting accuracy as that in the matching for all picture elements is obtained, and the time is shortened.

Abstract: PURPOSE:To sufficiently display the performance of an access part by connecting gate circuits among plural access parts through an address bus and a data bus and an accessed part so as to correspond to the plural access parts. CONSTITUTION:Plural gate circuits 50 and 53 are connected among the plural access parts 10, 11 connected through the address bus 40 and the data bus 41 and the accessed part 20 so as to correspond to the access parts 10, 11.

Thereby, the output timing of the addresses is made different from the input timing of data and the effective period of each address becomes 1.5 clocks. Consequently, respective access parts 10, 11 can sufficiently display their performance.

Title: Production of thin-film magnetic recording medium
Inventor: FUKAZAWA FUMIO
IPC: G11B5/85
Filed: 1989-05-20
Abstract: PURPOSE:To allow the control of an optimum film thickness distribution from the inner to outer peripheral side of a substrate by controlling the rate of infiltrating of sputtering particles to the rear side of the substrate 1 by the size and shape of a control hole. CONSTITUTION:A center cap 8 is mounted in a central hole 7 of the substrate 1. The hole 9 for control is bored at the center of the center cap 8 to control the quantity or position of the passage of the sputtering particles at the time of forming the whole or a part of an underlying film, magnetic film and protective film by sputtering. Namely, the sputtering particles can infiltrate to the rear of the substrate 1 through the control hole 9 but the rate of the infiltrating is suppressed as there is the center cap 8. The amt. of deposition on the rear surface of the substrate 1, therefore, decreases and the extreme increase in the film thickness on the central hole 7 side (inner peripheral side) of the substrate is prevented. The film thickness distribution of the underlying film, magnetic film, protective film, etc., from the inner to the outer peripheral side of the substrate is controlled in this way.
