Title: Radioactive gas monitor
Inventor: TORII TAKEO
IPC: G01T1/20
Filed: 1992-08-17
Abstract: PURPOSE:To enhance geometrical efficiency without increasing the counting rate of background and to achieve the compact configuration and a high sensitivity of a detector by bundling scintillation optical fibers in parallel, and bringing the optical fibers into close contact with the inner wall of a tank in a tubular shape. CONSTITUTION:Scintillation optical fibers 1 are bundled in parallel at the inner side of a gas sampling tank 2. A shading film 3 covers the surrounding part of the tank 2. A photomultiplier 4 is arranged at one end of the optical fiber 1. The optical fiber 1 comprises a core comprising a scintillator and a clad, whose refractive index is smaller than that of the core. When radiation such as beta rays enters, the scintillation light is emitted from the scintillator of the core. Therefore, when radioactive gas is introduced into the tank 2, the radiation cast on the side wall of the tank 2 causes the mutual reaction with the optical fiber, and the scintillation light is emitted. The scintillation light is effectively guided to both ends of the optical fiber 1 because the refractive index of the core is larger than the refractive index of the clad and detected with the photomultiplier 4.

Title: Method for measuring cross talk of polarization maintaining optical fiber
Inventor: SASAOKA HIDEYORI
IPC: G01M11/02
Filed: 1990-08-21
Abstract: PURPOSE:To easily and stably measure cross talk (CT) of an optical fiber in a state of being wound around a bobbin by measuring the cross talk while a bobbin diameter of a bobbin around which a polarization maintaining optical fiber (PM fiber) is wound is being reduced. CONSTITUTION:After a cavity 21a in a bobbin 21 made of ABS resin is sealed by closing members 23, 24, the cavity 21a is evacuated by a vacuum pump 25. This evacuation slightly shrinks the bobbin 21 to reduce a bobbin diameter, thereby releasing a side pressure from the bobbin 21 to a PM fiber 28 wound around the bobbin 21 and bending due to processing of the fiber 28. When CT is measured by a CT measuring apparatus in this state, it is possible to measure good CT. After the measurement of the CT, evacuation by the pump 25 is stopped and the closing members 23, 24 are released, whereby the bobbin 21 is expanded to its original diameter and a winding state of the fiber 28 restores. Thus secondary working of the fiber 28 such as making it into a core cable or a cord can be performed without any problem.
