Title: Gas detector
Inventor: MINOWA TAKESHI
IPC: G01N27/409
Filed: 1987-09-10
Abstract: PURPOSE:To improve the durability of a gas detector, by forming at least one layer of protecting layers with spinel type double oxides. CONSTITUTION:The electric characteristics of a detecting element part 2 are changed in correspondence with a surrounding environment. The change in electric characteristics is taken out with electrodes 4 and 6 as an electric signal. Thus the surrounding environment is detected. Porous protecting layers 8 and 10 are formed so as to cover the upper surface of the electrodes 4 and 6. At least one layer of them protects the electrode. At least one layer of the protecting layers 8 and 10 is formed with a spinel type double oxides. The composition ration between the oxides, which form said double oxides, is different from chemical equivalent. Therefore, a spinel structure is unstable. With the increase in temperature and the like, evaporation of a component having high vapor pressure is accelerated. Therefore, the component of the detecting gas, which is attached to the porous protecting layers 8 and 10, is readily scattered. The composition of the protecting layers 8 and 10 is changed by the evaporation. Since the remaining component becomes the state that is readily scattered, clogging of the protecting layers 8 and 10 is hard to occur.

IPC: G02B7/182
Filed: 1997-08-25
Abstract: PROBLEM TO BE SOLVED: To provide a piezoelectric scanner which is so structured as not to be affected by an external force. SOLUTION: A piezoelectric scanner 1 is equipped with four piezoelectric elements 4a to 4b which are joined to a base member 2 and attached to a scanned member 7 through corresponding joints 6a to 6d.

Abstract: PURPOSE: To avoid the temperature fluctuation in measured values for giving high measuring precision by controlling a local airconditioner so that the air temperature on an optical path may be almost equal to the atmospheric temperature near the optical path. CONSTITUTION: Due to the existence of a heat generating source such as a stage 8 etc., in a chamber 16, the temperature distribution is made so that the air inside the chamber 16 may be a little bit higher than the air temperature fed from an air supply port 1. At this time, a control device 21 controls an air blower 6a so that the stmospheric temperature on an optical path 10 may be almost equalized with the air temperature blown in the optical path 10, i.e. the temperature data a and c may be almost equalized with each other. Furthermore, the air blower 6a is controlled so that atmospheric temperature on another optical path 11 may be almost equalized with the air temperature blown in the optical path 11 i.e., the temperature data b and d may be almost equalized.  Resultantly, the fluctuation in the positional measured values due to the mixture of two fluids having temperature difference (measurement error) can be avoided thereby enabling the stage 8 etc., position to be measured with high precision.

Filed: 1995-09-06
Abstract: PROBLEM TO BE SOLVED: To emit white light as well as light of arbitrary color via a light emitting diode by jointing a light source and a light introduction plate via a wavelength converter having a fluorescent material. SOLUTION: Light emitted from the LED lamp 2 of a light source is introduced to space within a light introduction plate 1 via the joint thereof with the light source, and totally reflected in a planar direction, thereby allowing luminescence to be observed from a principal plane. In this case, the light source and the introduction plate 1 are jointed to each other via a wavelength converter 4 having a fluorescent material, Thus. a part of light emitted from the lamp 2 is absorbed by the fluorescent material of the converter 4 and at the same time, converted in wavelength for emission. Thereafter, the light is introduced to the plate 1. Consequently, the color tone of synthesized luminescence composed of the luminescence of the lamp 2 and luminescence converted with the converter 4 can be observed from a luminescence observation plane.  Alternatively, when light from the lamp 2 is all converted with the converter 4, the color tone of only luminescence converted therewith can be observed. Furthermore, when a high intensity blue LED is used as the LED lamp 2, the luminescence thereof including white color can be converted to a desired color tone.
