Abstract: PROBLEM TO BE SOLVED: To hold a disk substrate correctly without deformation of the disk substrate by a method wherein a disk holding surface is provided at a disk holding member and a disk is held from the inside with a pressure applied to the interior of the disk by the disk holding surface. SOLUTION: For a disk holding member 1, a main surfasce thereof is formed in a rectangular block-like shape and a plurality of disk holding grooves 2 for engagement with an inner circumferential part of a center hole of a disk are formed at the disk holding surface. Then, two pieces of the disk holding members 1 are inserted into the center hole of the disk and respectively fitted to opposite inner circumferential edges of the center hole and pressed toward the outer circumferential direction of the disk, and thereby the disk is held from its inner circumferential side. Or, a disk holding member 5 may be formed in a sheet-like shape with a plurality of disk holding grooves provided, and after the sheet-like member is rolled up and inserted into a center hole of a disk 6, a pressure is applied from the inner circumferential side to the outer circumferential side with the rolled-up member unrolled, and the disk 6 is held therewith.

Abstract: PROBLEM TO BE SOLVED: To precisely detect all over the projection on a magnetic recording medium by transferring a slider and detecting the projection with each projection sensor in the vicinity of both side surfaces. SOLUTION: A magnetic disk 1 is set on a rotating disk 112. The rotating disk 112 is rotated at a prescribed number of revolution with a rotation controller 113. A transferring stage 121 is transferred with a stage controller 125 so that the projection sensor positions in the inner peripheral edge of the disk 1. When the projection detecting sensor positions in the inner peripheral edge of the disk 1, the projection sensor is switched with the signal switching means of a signal processing circuit 1 30 to transfer the transferring stage 121 in the outer peripheral direction. A projection detecting signal is amplified with a signal amplifying circuit 131 and compared with the magnitude of a slice level signal with a signal comparing circuit 132. When the detecting signal is larger, the projection detecting signal is larger, the projection detecting signal is displayed on a displaying device 142 via a data output circuit 134.

Abstract: PURPOSE: To directly measure contact load in a running state equal to that of an actual machine by providing a magnetic core transforming the contact load into a magnetostriction and winding a signal detecting coil for taking out a detection signal around the magnetic core. CONSTITUTION: One pair of magnetic half bodies 11, 12 consisting of magnetic material such as ferrite are butted to each other through a gap material made of magnetic material 16 having a gap (g) to form a magnetic core 13. Then, a winding is applied to a winding groove 14 provided in the magnetic core 13 to form a coil 15. In this magnetic head 11, a recording and a reproducing with respect to a video tape being a magnetic recording medium are performed by a leakage magnetic field generated in the vicinity of the magnetic gap (g). However, in this load measuring instrument, it is different from the magnetic head that the magnetic core 3 is constituted while magnetic core half bodies 1, 2 are butted without having a gap equivalent to the magnetic gap (g). Consequently, a closed flow-path is formed without generating a leakager magnetic field and this load measuring instrument is not affected by a magnetic influence from the magnetic recording medium, etc.

Abstract: PURPOSE:To provide the walking exercise body for executing walking exercise whose prediction is difficult by providing a first centroid position varying means for varying a static centroid position of a walking exercise main body in an unstable direction, and a second centeoid position varying means for responding to this variation of the static centroid position and restoring it to the static centroid position. CONSTITUTION:The walking exercise body consists of a walking exercise main body, and a mechanical part contained in the walking exercise main body. The bottom face of an outside lower part semispherical shell body 1c is formed spherically, and a driving part rotates a first rotary disk 3a against a second rotary disk 3b by setting a first shaft 3c as a rotation center by a rotation of a motor 3e for varying a static centroid position, and inclines the walking exercise body1. This inclination is detected by an optical sensor 3j or an optical sensor 3n, and an electronic circuit in an electric substrate 3y drives a motor 3d and rotates a second rotary shaft 3f, and resets it to the static centroid position. These operation are executed continuously, and the walking exercise body 1 executes a walking operation, while tilting and oscillating.

Abstract: PURPOSE:To easily judge uneven coat, and to improve the accuracy of detection by installing a logarithmic conversion circuit into a photoelectric transducer transducing transmitted light into an electric signal and outputting the signal by a solid-state image sensing element receiving light and logarithmically converting an output signal from the solid-state image sensing element by the logarithmic conversion circuit. CONSTITUTION:CCD cameras 3 are disposed to the lower side of a magnetic recording medium 1, and CCD line sensors as photo-detectors and logarithmic conversion circuits logarithmically converting output signals from the CCD line sensors are arranged in the CCD cameras 3. The rate of change to the change of the film thickness of a magnetic layer of the logarithmically converted output signals is kept constant at all times even when the film thickness of the magnetic layer is within any range, and excellent detecting sensibility can be ensured even in a defective section, in which the film thickness of the magnetic layer is comparatively increased and which is close to the normal state of coating. Accordingly, sufficient detecting sensibility can be assured, thus allowing detection having high sensibility.
