Inventor: TSUZUKIBASHI EIICHIRO
IPC: B66B23/24
Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To diagnose whether a distortion exists in a steel cord or not by making a magnetic flux change generated in a new steel cord as a first detection result, making a magnetic flux change generated in a degraded steel cord as a second detection result, comparing both of these detection results and diagnosing the steel cords. SOLUTION: When steel cords 2b arranged in parallel in a range C are operated for a prescribed period and are degraded, distorted portions appear in the steel cords 2b and different magnetic flux changes are generated. As for the distorted portion, the cross sectional area of the steel cords 2b is changed on a lower side of a detecting part and a different magnetic flux change which is not generated in a new steel cord 2b is detected by the detecting part. A magnetic flux change detection result (first detection result) in the new steel cord 2b of a handrail 2 at the time of a delivery which is obtained by detecting the magnetic flux change and a magnetic flux change detection result (second detection result) in the steel cord 2b of the degraded handrail 2 are compared by a comparison part.

Abstract: PURPOSE:To prevent a cycling phenomenon, by lowering the control gain of a servomechanism in accordance with a state of a deviation output. CONSTITUTION:A controlled variable signal from a sensor is applied to a terminal 18. A circuit 19 detects a state that a controlled variable is varied in the direction being apart from a set value, and generates a high level signal when it is in the approaching direction.

Abstract: PROBLEM TO BE SOLVED: To enable high precision recording and reproducing of optical information recording media having different transparent substrates in thickness with one convergent optical system by providing a surface for giving discontinuous spherical aberration. SOLUTION: Incident light upon a 1st surface 311 of the objective lens 31 of discontinuity of its spherical aberration is converged from a transparent substrate 52 of a 1st optical information recording medium DVD (digital video desk) 51 onto an information recording surface 53. In this case, a numerical aperture (NA)1 required for reading the DVD 51 is decided by a wavelength λ of a laser light source 12, and information can be read out, provided the numerical aperture is equal to or more than the above decided value. Then, in the case of a 2nd optical information recording medium CD 54, provided a ratio of a numerical aperture NA2 to the wavelength λ is 1.75, enough read-out performance can be obtained. Therefore, in order to converge a good light spot even when the thickness of the substrate 55 is increased under the numerical aperture NA2 or a larger numerical aperture NA3 at the time of reproducing the CD 54, the surface for making spherical aberration of emitted light flux discontinuous is equipped on an aperture corresponding to the numerical aperture NA3 in an optical path member between the light source 12 and the recording surface 54, so as to give a discontinuous aberration characteristic of reducing return light to a photodetector 13.
