Title: Thin film optical element and its production
Inventor: MIYAWAKI MAMORU
IPC: G02B6/13
Filed: 1984-09-14
Abstract: PURPOSE:To improve the coupling efficiency of a guided light in the input and the output and to improve the optical modulation efficiency by distributing ions more densely on the inside of a substrate in the substrate thickness direction than the surface of the substrate in optical coupling parts of end faces of an optical waveguide to and from which the guided light is inputted and outputted. CONSTITUTION:A parallel light 8 from an He-Ne laser having 6328Angstrom  wavelength is condensed on a polished optical waveguide end face 3 in the thickness direction of an optical waveguide 2 by a cylindrical lens 5 and is coupled into the optical waveguide. A guided light 9 is diffracted by a surface acoustic wave 10 which is generated by applying an RF power to a comb-shaped electrode 7, and the diffracted light is discharged from an optical waveguide end face 4 and becomes a parallel light by a lens 6. The optical waveguide 2 is buried in a layer 20 having a low refractive index near optical waveguide end faces, and therefore, electric field intensity distributions of the input/output light and the guided light approximate each other very much, and 85% high coupling efficiency is obtained. The guided light coupled from the end face is pulled up to the surface side of the substrate according as going to an optical function part of the interaction between the surface acoustic wave and the light, and a high diffraction efficiency of the guided light due to the surface acoustic wave is obtained.

Title: Substrate for disk
Inventor: YOKOTA SHOJI
IPC: G11B7/26
Filed: 1996-07-23
Abstract: PROBLEM TO BE SOLVED: To improve flatness and minimize double refraction by forming an inner circumferential non-recording area thin and setting a thick part in an outer circumferential non-recording area. SOLUTION: When a disk is manufactured, an inner circumferential non- recording area 3 or a surface opposite to the area is made a flat face thereby to form a thin part 3a in order to eliminate a bend of a substrate A1 due to a film stress when a protecting layer is formed and to reduce double refraction at a surface of the disk. When an area of the thin part 3a is not larger than 3-30% an area of one surface of the substrate A1 including an opening 4, the stress is dispersed insufficiently within the substrate A1, which bends the substrate A1. If the area is not smaller than 3-30% the area, a strength is not enough. A thick part 1a thicker than a recording area 2 is formed in an outer circumferential non-recording area 1, thereby to improve rigidity of the substrate A1 and prevent the substrate A1 from being deformed or bent.  At the same time, since the thick part 1a is thicker than the area 2, the area 2 is prevented from being damaged when a cartridge is installed in the optical disk during the manufacture of the optical disk or when the optical disk is used.

Abstract: PURPOSE:To make control without hunting of X-ray tube current even in the case of a low count rate by preliminarily setting X-ray tube current in such a manner that the intensity of the X-ray of the specific wavelength obtd. by spectrally splitting the X-rays radiated from the X-ray tube attains a target value. CONSTITUTION:The intensity of the X-ray of the specific wavelength obtd. by spectrally splitting the X-rays from the X-ray tube 1 with a spectral crystal 2 is detected for about one second by a 1st detector 6 prior to the measurement of the X-ray absorptivity of analyzing sample 4. The pulses corresponding to the X-ray intensity from the detector 6 are counted by a 1st counter 10. The preset count rate is divided by the count value per unit time of the counter 10 in an arithmetic control part 14. The current X-ray tube current is multiplied by the divided value to calculated the target value of the X-ray tube current. The X-ray tube current to be supplied to the X-ray tube 1 is reset so that the saturation of the output of the 2nd detector to be detected through the sample 4 is prevented.
