摘要： PURPOSE:To efficiently make reactional light react with a photocatalyst in a solution without leaking the reactional light to the outside by reducing the refractive index of an inner wall of a reactional vessel from that of a reactional solution. CONSTITUTION:This photodecomposition apparatus 1 is equipped with a vessel 4 formed from a Teflon(R) pipe having about 100mm diameter and about 2m length, a window 7 of a quartz glass plate at the lower end thereof and a valve 11 for holding and taking out a reactional product 6 in the upper part of the vessel. A solution 3 prepared by dispersing a photocatalyst 2 of SrTiO3/NiO in water is introduced from an injection port 10. The refractive index of the solution 3 is about 1.33 and the refractive index of the inner wall of the vessel 4 is about 1.30. The reactional light 5' incident thereon from the window 7 propagates while totally reflecting from the wall surface of the Teflon(R) and the reflection efficiency can be raised. The produced H2 and O2 gases are taken out through the valve 11 to the outside. A taking-out port 9 is located in the upper part of the vessel and the incident window 7 of the reactional light 5 is located on the lower side. This is because if the reactional product 6 having a low refractive index is collected near the window 7, the light 5 from a light source is reflected to lower the reactional efficiency.

摘要： PROBLEM TO BE SOLVED: To provide a light guide which can shorten an optical path length even without using an expensive high-NA optical fiber with low heat resistance and a small-sized light irradiation device using the same. SOLUTION: The light guide 4 is characterized by that an optical rod 7 in a shape of a fulcrum of a right circular cone has its large-diameter end part 7a fitted to one terminal of an optical fiber bundle. Further, the light irradiation device comprises the light guide 4 and a light source 3, so any special large-NA optical fiber is not used for the optical fiber bundle in the light guide 4 and even when the angle A1 of incidence on an optical rod is large, the angle B1 of projection from the optical rod becomes small, so that the optical path length L1 can be made short.

摘要： PROBLEM TO BE SOLVED: To obtain an optical fiber and other silica glass products reduced in deterioration by an ultraviolet irradiation, and to provide its production. SOLUTION: This production of silica glass products comprises the 1st step of irradiating an electromagnetic wave to a silica glass product as a starting material so as to cause any glass defects and the following 2nd step of immersing it in the atmosphere of hydrogen glass so that it may be significantly prevented to increase a light absorption in an ultraviolet region caused by ultraviolet irradiation. Preferably, there are used an ultraviolet ray, vacuum ultraviolet ray, X ray, and γ ray as the electromagnetic wave, and the exposure is 10 to 10 Gy. Furthermore, the production needs the 3rd step of irradiating an electromagnetic wave again after the 2nd step so as to improve an ultraviolet resistance of esp., the optical fiber. Preferably, the electromagnetic wave in the 3rd step is an excimer laser or γ ray. The 4th step may be used so as to remove hydrogen from the silica glass products after the 3rd step.

摘要： PURPOSE: To charge a cell at any time after the scope is used by connecting the plug to an outlet while the fiber scope can be held and attached to the wall or the floor of the outlet so as to maintain the scope to be easily used anytime. CONSTITUTION: The end of the light guide 2 where an eyepiece 4 is attached is equipped with a 2.5-V small tungsten lamp (or halogen lamp) 5, a secondary cell 6 which can be charged, and a charger 7 to generate DC voltage from 100V AC power supply to charge the cell 6, and a plug 8. By connecting the plug 8 to an outlet of commercial power supply, the secondary cell 6 is charged while the whole body is held and attached to the wall or the floor of the outlet. After the secondary cell 6 is charged to a specified amt., the charging circuit is automatically turned off by a switch 9. In this case, the image guide 1 consists of quartz glass fibers to produce a bright image to be observed, while the light guide 2 consists of multicomponent glass to make the outer diameter small.

摘要： PURPOSE:To emit light by the light emitting plate with small power source capacity by providing an optical waveguide formed on a substrate, a light source which emits light into the optical waveguide, and a light leak means which leaks the light transmitted through the optical waveguide to the surface side. CONSTITUTION:The light emission plate is constituted including the optical waveguide 7 formed on the substrate 6, the light source 9 which emits its light into the optical waveguide 7, and the light leak means which leaks the light transmitted in the optical waveguide 7 to the surface side, and the light leak means is so constituted that the light leaks from the surface of a light waveguide part 7 placed in a rough state A. Namely, the transmitted light in the optical waveguide 7 is emitted to the surface side of the optical waveguide 7 through the operation of the light leak means, so the optical waveguide 7 is designed and the design illuminates. Thus, the light emitting plate utilizes the light leaking from the optical waveguide 7 to form a decoration body with complicate with the irreducible necessary light source 9, thereby emitting the light with the small-sized, inexpensive power source.

摘要： PURPOSE:To detect even the gas to be detected of a relatively low concn. and provide the strong fiber so that the gas can be detected distributively over a wide range with a single fiber by consisting the core part and clad part of fluoride glass and forming a recess on the surface along the optical axis direction. CONSTITUTION:The fluoride optical fiber 13 is constituted of the core 11 consisting of the fluoride glass and the clad 12 consisting of the fluoride glass and has the recess 14 along the optical axis. The length D in the inlet part of the recess 14 in the section orthogonal with the optical axis thereof is smaller than the length E of the inside part thereof. The transmittance to the light near a wavelength (middle IR light region) at which the IR adsorption of the gas to be detected arises is extremely increased by forming both of the core part and the clad part of the fluoride glass. The specific wavelength of the evanescent wave propagating on the outside of the core part of the optical fiber is absorbed when the gas to be detected in an atmosphere gas enters the recess of the clad part. The increase quantity of the absorption loss of the IR oscillation of the relatively low-concn. gas to be detected is detected in this way.

摘要： PURPOSE:To easily monitor quantity of incident light by bundling plural pieces of optical fibers around an incident end, separating one of such fibers from the remaining optical fiber at the mid-point to an exit end and guiding the front end thereof to a monitor light exit end. CONSTITUTION:The light from a light source (not shown in the figure) is entered from the incident end 1 to each of plural pieces of the optical fibers and the greater part of the light is transmitted to the exit end 2. An object to be irradiated can, therefore, be subjected to sterilization by UV rays, etc., if said object is disposed in front of the exit end 2. On the other hand, part of the incident light is emitted via a monitor guide 4 and the monitor light exit end 5. A fluctuation or flickering in the quantity of the light emitted from the light source is, thereupon, detected if the monitor light is received by a sensor (not shown in the figure). Adequate constitution is thus permitted according to the type of the light source and the performance of the sensor.
