    Impact ionization rates of holes in AlxGa1−xSb (1991)

    Notes: This paper discusses the impact ionization rates of holes in AlxGa1−xSb near x=0.06, where resonance impact ionization is expected. Resonance impact ionization did not occur in a range of the electric field we studied. We evaluate the impact ionization of holes at the spin-split-off band theoretically, and show that our measured result is reasonable.

    Structure and magnetic properties of Sm2(Fe,Mn)17Nx coarse powders with high coercivity : The 41st annual conference on magnetism and magnetic materials (1997)

    Notes: The influence of a substitution of Mn for Fe in the Sm2(Fe,Mn)17Nx alloys on the structure and the magnetic properties was studied. Sm2(Fe,Mn)17Nx alloy powders of 32–74 μm in particle size with several values of x were successively synthesized using NH3+H2 gas. It was found that the primary phase of the powders maintained the Th2Zn17-type structure in the wide range for 0〈x〈6. On the other hand, the coercivity of the powders remarkably increased for x〉3. The Sm2(Fe0.95Mn0.05)17N5 powder proved to have a coercivity of 0.62 MA/m (7.7 kOe), without a fine grinding. Microstructural analysis by transmission electron microscopy and energy-dispersive x-ray analysis revealed the powder consisted of Sm2(Fe,Mn)17N3 nanocrystalline grains of 10–30 nm in diameter surrounded by Mn-enriched amorphous phase. © 1997 American Institute of Physics.

    New mechanical grinding process for anisotropic Sm2Fe17Nx powder with a nanocrystalline structure : The 41st annual conference on magnetism and magnetic materials (1997)

    Notes: A new mechanical grinding (MG) process in NH3 and subsequent nitriding in N2 without a crystallization treatment was developed for synthesizing Sm2Fe17Nx powders. This process features a shorter MG time compared to conventional MG to prevent amorpharization of the alloy structure and to avoid hydrogen in the ground powders which promotes a diffusion of nitrogen atoms into their particles. The Sm2Fe17Nx powder with x=3.2 prepared by grinding for 10 h and subsequent nitriding at 723 K for 6 h showed magnetic anisotropy and its magnetic properties were Ir=1.00 T, iHc=0.61 MA m−1, and (BH)max=129 kJ m−3 (16.1 MGOe). © 1997 American Institute of Physics.

    Thermoelectric properties of the skutterudite Co1−xFexSb3 system (1998)
    [S.l.] : American Institute of Physics (AIP)

    Notes: We have examined the phase equilibrium and thermoelectric properties of Co1−xFexSb3 ternary system up to high iron context x=0.40. Traces of Sb were observed in the hot-pressed samples with x≥0.06, and FeSb2 (Fe0.73Co0.27Sb2) compound with marcasite structure was also observed in the samples with x≥0.25 by x-ray diffraction. The lattice parameter of Co1−xFexSb3 is slightly larger than that of the binary compound CoSb3. The Seebeck coefficient and the electrical resistivity are generally reduced by the substitution for Co by Fe. The thermal conductivity is also reduced by the substitution especially at high iron content region. These behaviors of the thermoelectric properties in the samples with low iron content are ascribed to the substituted Fe, while those in the samples with high iron content are ascribed to the precipitated FeSb2 (Fe0.73Co0.27Sb2) compound. For x≤0.04, the figure of merit for Co1−xFexSb3 decreases with increasing x. However, above x=0.06 the figure of merit increases with x and as a result, Co0.75Fe0.25Sb3 has a maximum value of figure of merit of 4.8×10−4 K−1 at 773 K. This value is much larger than the maximum value for CoSb3 3.2×10−4 K−1 at 482 K. © 1998 American Institute of Physics.

    Dynamic mode force microscopy for the detection of lateral and vertical electrostatic forces (1993)

    Notes: In this letter, a variant of scanning force microscope for detecting attractive forces is reported. The force gradients of the attractive forces acting in two orthogonal directions were detected simultaneously from the resonant frequency shifts of a cantilever oscillating in two directions. Using the fine electrode sample, the distributions of the electrostatic forces acting in lateral and vertical directions were visualized separately.

    An x-ray spectrometer for Compton scattering : Proceedings of the 4th international conference on synchrotron radiation instrumentation (1992)

    Notes: An x-ray spectrometer has been designed and constructed for Compton scattering measurements using 40–70 keV x-rays from an ellipsoid multipole wiggler (EMPW) installed in the accumulation ring of the National Laboratory for High Energy Physics at Tsukuba. The spectrometer has four sets of a Cauchois-type energy analyzer and an imaging plate, which are arranged on the surface of a cone and share a scattering angle of 160°. In each energy-analyzing system, to increase signal to noise ratio a set of vertical and horizontal slits are inserted between the analyzer and the imaging plate. A resolution of 0.13 a.u. in terms of electron momentum was achieved. A Compton profile of a vanadium single crystal was measured with an integrated counting rate of 400 counts/s.

    Monoclonal antibody analysis of keratin expression in carcinomas of sweat glands (1992)

    Notes: Characteristics of keratins of live carcinomas of sweat gland origin were immunohistochemically investigated with several antikeratin monoclonal antibodies with differing specificities. Specimens were obtained from two cases of mucinous carcinoma of the skin, two cases of classic type of eccrine adenocarcinoma, and a case of eccrine porocarcinoma. The tumor cells of mucinous carcinoma expressed only simple epithelial keratins. In a case of eccrine adenocarcinoma, simple epithelial keratin 19 was diffusely expressed. The expression of the other simple epithelial keratins was confined to the luminal cells, whereas the remaining tumor cells further expressed stratified epithelial keratins. Eccrine porocarcinoma and a second case of eccrine adenocarcinoma did not express simple epithelial keratins, although stratified epithelial keratins were diffusely expressed. These data suggest that carcinomas of sweat glands express various combinations of simple and stratified epithelial keratins. Development of additional data along these lines may help to further define their classification.

    Morphogenesis of the cornoid lamella: histochemical, immunohistochemical, and ultrastructural study of porokeratosis (1991)

    Notes: To elucidate the morphogenesis of cornoid lamellae (CL) in porokeratosis, skin lesions of three cases of disseminated superficial actinic porokeratosis and a case of linear porokeratosis were examined. By N-(7-dimethylamino-4-methyl-3-coumarinyl)maleimide staining, SH groups were present in the living layer of the epidermis beneath CL and irregularly disappeared at the bottom of CL, whereas SS linkages appeared in dyskeratotic cells in the living layer and in the irregularly shaped cell membranes of the horny cells. Epidermis beneath CL showed an increased and irregular involucrin expression. Ultrastructurally, the living keratinocytes contained many cytoplasmic vacuoles and had a smaller number of lamellar bodies than normal. Intercellular lamellar sheets were incompletely formed. The dyskeratotic cells and the lower horny cells contained many small vacuoles but formed a marginal band. The horny cells of CL also formed a marginal band and, further, a keratin pattern. CL may be formed by hyperproliferative atypical kertatinocytes which keratinize rapidly and irregularly and show defective desquamation due to the paucity of intercellular lamellar sheets.

    Proliferating trichilemmal cyst with apocrine-acrosyringeal and sebaceous differentiation (1991)

    Notes: An adnexal tumor on the scalp of a 74-year-old woman is described. Histologically, the tumor was composed of cystic structures showing typical trichilemmal keratinization. The tumor cells in the cyst walls often formed duct-like or squamous eddy-like structures and occasionally showed vacuolation or poromalike change. Ultrastructurally, some tumor cells showed differentiation either toward the acrosyringium or sebaceous cells. From these findings, the present tumor is considered to differentiate toward various parts of the hair follicle including infundibulo-isthmus epithelium, apocrine acrosyringium, and sebaceous cells.
