    The effect of Ag doping on superconducting properties of the Bi-Pb-Sr-Ca-Cu-O tape fabricated by an Ag sheath (1992)
    [S.l.] : American Institute of Physics (AIP)

    Notes: The powder-in-tube method using an Ag sheath is applied to achieve high current capacity in the tapes of Bi-Pb-Sr-Ca-Cu-O (BPSCCO) with the high-Tc phase (Tc=110 K), by a combination process of cold working and sintering. Two kinds of the BPSCCO powder with and without Ag doping are used as the materials for tape fabrication. The morphology, structure, and critical current density Jc are investigated on the tapes by x-ray diffraction, differential thermal analysis, scanning electron microscope, magnetic susceptibility, and I-V curves. The optimum sintering conditions to obtain a maximum in the value of Jc at 77 K and 0 T are presented in the Ag-doped tapes and the nondoped ones. An improvement in the Jc vs B properties up to 1 T at 77 K is presented in the BPSCCO tape by Ag doping. The Ag doping causes neither change in the value of Tc (=110 K) nor decomposition of the high-Tc phase.

    Development of an imaging vacuum-ultraviolet monochromator in the normal incidence region (1996)

    Notes: An imaging vacuum-ultraviolet monochromator has been developed to provide the space-resolved impurity line emissions from magnetically confined plasmas. With minor modifications of a commercial normal incidence monochromator, a pinhole entrance slit and a microchannel plate detector displaced away from the exit slit, the instrument performs two-dimensional spectroscopic observations in the wavelength range from 400 to 2000 A(ring). Ray tracing has been performed to understand the spatial imaging properties in the practical geometric configuration. The measured spatial resolution is about 0.5 and 1 mrad in dispersion and vertical plane, respectively, with the entrance slit of 0.1 mm width and height. The results of the testing experiments and the measurements carried out on the JIPP T-IIU tokamak plasma are presented and discussed. © 1996 American Institute of Physics.

    Interdiffusion and interfacial reaction between an YBa2Cu3Ox thin film and substrates (1988)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 53 (1988), S. 1437-1439

    Topics: Physics
    Notes: Interdiffusion and interfacial reaction between a sputter-deposited YBa2Cu3Ox thin film and substrates (MgO, sapphire, quartz, and Si) have been investigated by 2.7 MeV 4He+ Rutherford backscattering spectrometry. The diffusivities of Cu in the substrates and of the substrate elements (Mg, Al, and Si) in the Y-Ba-Cu-O thin films have been determined over the annealing temperature range from 876 to 1226 K in an oxygen atmosphere. Among three metallic elements of Y, Ba, and Cu, Cu diffuses the fastest into the substrates. Copper silicide is observed in the interfacial region between the film and the Si substrate. Among these substrates, MgO is suggested to be the most stable on annealing.

    A nonlinear analysis of the kinetics of reversible structural relaxation in Co-Fe based metallic glasses (1988)
    [S.l.] : American Institute of Physics (AIP)

    Topics: Physics
    Notes: The kinetics of reversible resistivity changes during structural relaxation in various Co-Fe based metallic glasses was examined using a nonlinear kinetic form Ψ=exp[−(t/τm)n]. It was found that the data excellently fit the nonlinear kinetic form. The compositional dependence of the kinetic parameters (distribution parameter n, activation energy Ea, and preexponential factor τ0) were obtained, and the microscopic mechanism of atomic rearrangements during the relaxation is discussed.

    Nd-Fe-B die-upset and anisotropic bonded magnets (invited) (1988)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 64 (1988), S. 5285-5289 
    Details
    ISSN: 1089-7550

    Topics: Physics
    Notes: The hot working conditions were examined for Nd-Fe-B die-upset magnets. The Nd14Fe80B6 ternary composition has the best workability (die upsetting) from stress-strain curves for the initial stage of die upsetting at hot working temperature. The compression ratio defined as the inverse of reduction in height should be larger than 4 to have materials aligned. Alignment of c axis along the compressive stress direction is obtained, but grain coarsening occurs during die upsetting. Of several additional elements investigated, Ga is the best for enhancing the coercivity with a little sacrifice of remanence and no deterioration in hot workability. Typical magnetic properties for Nd14Fe79.25B6Ga0.75 die-upset magnets are Br =12.4 kG, iHc =19 kOe, and (BH)max =36 MGOe. The irreversible loss after exposure up to 160 °C is under 10% (Pc =2). The iHc of powder made by crushing the die-upset magnets is nearly independent of particle size. Decrease in iHc by pulverizing to several hundred micron is about 2 kOe. Anisotropic bonded magnets were developed using this powder. Best energy products of injection and compression molded magnets with Ga addition are 10 and 15 MGOe, respectively. The irreversible losses after exposure up to 120 °C is lower than 5% (Pc =2), which is enough thermal stability for polymer-bonded magnets.

    Mathematical Evaluation of Effective Moisture Diffusivity in Fresh Japanese Noodles (Udon) by Regular Regime Theory (2000)

    Notes: The effect of moisture content and temperature on the effective moisture diffusivity was investigated to have the optimal drying condition of Japanese noodles (Udon) using regular regime theory. The drying of fresh Udon of different moisture contents was carried out under constant conditions of relative humidity and airflow at 20, 30, and 40 °C. The existence of regular regime periods for fresh noodles was experimentally verified. Effective moisture diffusivity obtained ranged from 2.1 × 10 -7 to 3.7 × 10 -7 cm2 s-1. The effect of temperature on effective moisture diffusivity was adequately modeled by the Arrhenius relationship, although the effect of moisture content was quite small.

    Notes: We report a 3-month-old male infant with marked folding of the skin, who manifested mental retardation and delayed growth at the age of 31 months. Histological examination of the folded skin disclosed smooth muscle hamartomatous changes. To our knowledge, this represents the third reported case of folded skin with an underlying smooth muscle hamartoma.
