Abstract: PROBLEM TO BE SOLVED: To realize a semiconductor laser operating with a low threshold value in the blue violet wavelength region by forming a waveguide resonation structure suitable for the semiconductor laser using a nitride material, conventionally unsuitable for formation of waveguide or resonator, and forming a high reflectance film of DBR structure on the end face of the resonator SOLUTION: Epitaxial growth is carried out on the (0001) C plane of a sapphire substrate up to a layer 3 of GaN and then selective growth is carried out up to a high reflectance film 8 of DBR structure including the waveguide structure of layers 5 through 7 using a pattern of the insulation mask 4. The waveguide has BH structure of real refractive index waveguide type where an emission active layer is buried in an optical waveguide layer.

Title: Method for measuring intake radiation exposure
Inventor: ISHII KEIICHIRO
IPC: G01T1/163
Filed: 1990-07-23
Abstract: PURPOSE:To evaluate a dose with high accuracy by preliminarily storing standard excretion curves due to the properties of radioactivity and calculating the standard excretion curve approximate to the measured value of the intensity of intake radioactivity in excretion to estimate real intake radioactivity. CONSTITUTION:A large number of standard excretion curves predetermined at every properties are calculated to be stored and, when there is real intake, the measured value at least at two points of time is compared with the standard excretion curves and the properties of intake radioactivity are estimated from the similar relation between both of them. Therefore, intake quantity and exposure can be accurately estimated on the basis of the standard excretion curve specified from the estimated properties of radioactivity. Since the intensity of the real intake radioactivity in excretion is measured with the elapse of time, alpha-ray and beta-ray emitting radioactivities are simultaneously discriminated and measured on the basis of the difference between emission attenuation times using the excretion and a liquid scintillator. Further, since gamma-rays of high and low energies are simultaneously discriminated and measured, the intensity of radioactivity in the excretion can be accurately measured.
