Abstract: PURPOSE:To make it possible to supply a volatile material stably, by extending a volatile material feeding pipe from a reserve container, which contains the volatile material to the height of the liquid surface of the voltatile material in an evaporating container, and providing a bubble shield, which prevents the inflow of bubbled foam-state carriers into the reserve container, at the tip of the feeding pipe. CONSTITUTION:A voltatile material feeding pipe 11 is extended downward vertically to the height of the liquid surface of a volatile material 2 in an evaporating container 1 from the bottom of a reserve container 10. An inverted conical bubble shield 13 is provided at a port 12 of the volatile material feeding pipe. A volatile material introducing port 14 to the reserve container 10 and an introducing port valve 15 are provided on the reserve container 10. The voltatile material is inputted to the height of the feeding pipe port 12 from the reserve container 10. Then the introducing port valve 15 is closed. Under this state carrier gas is introduced into the evaporating container, and bubbling is started. Then the volatile material is vaporized and flows out of the container. The height of the liquid surface is lowered. The material is supplied into the evaporating container 1 by that amount all the time. When the material is supplied to the height of the feeding pipe port 12, pressure balance is obtained. Then the feeding is stopped. In this way, the height of the liquid surface of the volatile material in the evaporating container 1 always becomes constant at the height of the feeding pipe port 12. The passing time of the bubble state carrier gas within the volatile material becomes constant, and the feeding amount becomes constant.

Filed: 1998-06-29
Abstract: PROBLEM TO BE SOLVED: To provide a flush type optical waveguide which may be easily produced and has sufficient optical performance by embedding a core having an approximately rectangular cross-sectional shape into a groove and the process for producing the same. SOLUTION: This optical waveguide has a clad 12 having the groove of an approximately recessed shape in the cross-sectional shape with respect to a propagation direction of light and a core 11 which is embedded in the groove and has the approximately rectangular cross-sectional shape and satisfies the relation D>W when the cross-sectional depth of the core 11 is defined as D and the cross-sectional width as W. As a result, the single mode optical waveguide having no difference in propagation speed may be obtd. if the ratio of D and W is set according to the difference in the refractive index of the core 11 and the clad 12. Since the front surface of the core 11 is not coated with a clad layer, there is no need for using a film process in the formation of the clad 12 and, consequently, the production is made easy.

Title: Radioactive gas monitor
Inventor: TORII TAKEO
IPC: G01T1/00
Filed: 1993-07-23
Abstract: PURPOSE:To reduce the background count rate by inserting a beta-ray shielding film between the inner and outer layers of scintillation optical fiber bundle, amplifying the detection signal of the fiber bundle, counting the detection signals by means of an anticoincidence circuit, and subtracting the coincidence count. CONSTITUTION:When a gas containing a radioactive component is fed to a gas sampling tank 8, the radiation traverses the inner layer of an optical fiber 1 to emit a scintillation light which propagates through the fiber 1 and arrives at a photoelectric amplifier. Since beta-rays are shielded by a beta-ray shielding film 9 formed between the inner and outer layers, the scintillation light is emitted only from the optical fiber 1 of inner layer. In case of background radiation having high transmittance, it transmits through the fibers 1 in the inner and outer layers to emit light simultaneously but it is not counted because of the subtraction in an anticoincidence circuit. This constitution reduces the count rate of background radiation even if the shielding film is thin.
