Patent JP-S63234126-A (JP)
Title: Optical temperature measuring instrument
Inventor: HISHIKARI ISAO
IPC: G01K11/12
Filed: 1987-03-23
Abstract: PURPOSE:To measure temperature with high sensitivity by projecting and photodetecting laser light with specific wavelength on an interference film filter as a temperature sensing part through an optical fiber, detecting light from the optical fiber by a detector, and measuring the temperature. CONSTITUTION:Light from a laser light source 1 which generates the laser light with the specific wavelength is projected on the multilayered interference film filter 3 as the temperature sensing part through the optical fiber 21. Light transmitted through the filter 3 is guided out through an optical fiber 22 and photodetected by the detector 4, and a measuring means 5 measures the temperature from the output signal of the detector 4. Namely, the filter 3 shifts in transmission wavelength characteristics to the long-wavelength side from A to A' as the temperature T rises and the wavelength of the laser light is constant as shown by B, so the degree (product) of the overlap between A or A' and B varies with the temperature T and radiant energy incident on the detector 4 varies. The measuring means 5 measures the temperature T from the output of the detector 4 by an arithmetic expression found by an experiment, etc.

Title: Vibration damping type bearing device for rotary machine
Inventor: NISHIMOTO KOJI
IPC: F16F15/03
Filed: 1987-03-23
Abstract: PURPOSE:To enhance the stability of a rotary shaft and to disable the rotation at a high speed by providing a damper mechanism composed of a nonmagnetic metal member and magnets arranged closely adjacent to the former, in a gas bearing provided in the intermediate section of the rotary shaft. CONSTITUTION:A ring-like plate shape nonmagnetic metal member 6 is secured to the outer side surface of a gas bearings 5 provided in the intermediate section of a rotary shaft 1 which is supported at both ends by bearings 3. A plurality of magnets 7 are arranged in the vicinity of both side surfaces of the metal member 6 so as to constitute a damper mechanism D. With this arrangement, when the rotational shaft 1 on rotation is displaced, eddy current is produced in the metal member 6 in accordance with the displacement of the metal member 6 in the magnetic field of the magnets 7, and acts to decrease variations in magnetic flux passing through the metal member 6. Accordingly, the displacement of the metal member 6 is controlled to restrain the displacement of the rotary shaft 1 by means of the pressure of compressed gas.

Patent JP-H03268472-A (JP)
Title: Semiconductor laser and system equipped with this semiconductor laser
Inventor: NAGATA HISAO
IPC: H01S5/00
Filed: 1990-03-19
Abstract: PURPOSE:To eliminate the need for other optical elements, simplify system structure and facilitate optical alignment by reflecting light from a light waveguide passage to the outside of a semiconductor laser by way of a diffraction region and changing the incident angle of laser light, according to the change in the oscillation wavelength of said laser light. CONSTITUTION:In a diffraction region 5 installed in a light waveguide passage 14 of a semiconductor laser 15, there enters a light which shuttles in the light waveguide passage 14 where at least a part of lights permeate through the diffraction region 5. The refraction factor of the light changes at a specified frequency in the diffraction region 5. The frequency fails to satisfy the plug reflection condition in terms of the wavelength of a gain peak of laser light. Therefore, the light from the optical waveguide passage 14 in the diffraction region 5 causes plug reflection and undergoes virtually no reflection. Since the diffraction region 5 serves as a spectroscope, if a light detection means is laid out so that this emission light may enter the outside of the semiconductor layer 15, it will be possible to detect the intensification of the laser light and change in its wave length. This construction makes it possible to facilitate optical alignment and simplify the assembling of structure as well.
