    Notizen: Controlling vertical Bloch line (VBL) position and stripe domain chopping in multiple stripe domains, aligned in parallel by a period of 12 μm, are studied experimentally using a 5-μm bubble garnet film. Patterned high coercive-force CoPt films aligned in parallel are used for stabilizing the stripe domain. During the stripe stretching process, the VBL motion at the stripe head was controlled by the dc conductor current to get two different wall states: one with a VBL at the stripe head and the other without VBL. Stripe chopping experiments for VBL detection have been performed using hairpin and meandering conductors. We found that the meandering conductor presents excellent characteristics; the bias field margin and the chopping pulse amplitude margin are 58 Oe±6% and 133 mA±11%, respectively, for one stripe. VBL generation by the meandering conductor has also been studied using the same sample.

    Notizen: The tilt angle of the c axis from the film normal in Co-Cr flexible media fabricated by continuous sputter deposition is determined by analyzing torque curves, and is compared with that obtained by x-ray diffraction. A discussion is given concerning the perpendicular anisotropy constant obtained from torque curves with and without considering such a tilt angle of the c axis.

    Notizen: The effect of Pr on both the magnetic properties and microstructure of Co-Cr alloys is discussed. The saturation magnetization Ms and perpendicular magnetic anisotropy Ku at room temperature is found to increase with Pr, becoming maximum at about 0.5 wt. % Pr, and then decreases monotonously. The microstructure is also changed with Pr, leading to a less-defined columnar structure. However, no significant change is found in the Auger spectra for various contents.

    Notizen: The photoluminescence decay of GaAs/AlGaAs quantum wells was successfully measured at room temperature by using 660-nm picosecond light pulses from an AlGaInP diode laser driven by short pulse current. Our experimental results reveal that picosecond light pulses from visible diode lasers may be widely applicable, in place of mode-locked gas, solid-state, or dye lasers, for studying the fast carrier recombination properties of many kinds of materials including GaAs and AlGaAs in the wavelength region of deep red to infrared.

    Notizen: A detailed investigation of the structure of Ho19Co81 sputter-deposited amorphous films has been carried out by high resolution transmission electron microscopy. A columnar structure which is amorphous and is well developed along the thickness direction contains microcrystalline regions which provide a clear lattice image in the micrographs. Such microcrystalline regions distribute locally and the structure is very close to that of HoCo5 intermetallic compounds. The change in magnetization in an isothermal annealing experiment in vacuum is also discussed. The activation energy which was deduced from the temperature dependence of the 50% change of magnetization was found to be 0.56 eV.

    Notizen: A low-pressure plasma spraying technique for depositing high Tc Y-Ba-Cu-O thick films has been developed. Films with a thickness range of 20–100 μm have been prepared by using Y0.3Ba0.7CuOx powders. After post-annealing in oxygen for 1 h at 950 °C, the films, which were deposited on a nimonic alloy substrate heated at 650 °C during spraying, exhibited a zero resistance temperature of 90.6 K with a transition width (90%–10%) of 2 K and a critical current density (77 K, 0 T) of 690 A/cm2.

    Beschreibung / Inhaltsverzeichnis: Résumé On a pratiqué des radiographies däns deux plans perpendiculaires afin d'estimer la fusion osseuse après arthrodèse inter-transversaire. Les patients sont examinés cliniquement et l'état radiologique est comparé au résultat clinique. On sait que l'arthrodèse postéro-latérale inter-transversaire est capable de fusionner presque complètement le segment mobile du rachis. Cependant, le pourcentage de fusion rigoureusement certaine n'est que de 27%, mais il atteint 91% si l'on y ajoute les fusions partielles. Le pourcentage de fusion estimé par le radiologue sur des clichés conventionnels est de 82%, ce qui est identique aux autres séries publiées. Du point de vue clinique, le résultat est satisfaisant dans 82% des cas, mais sans corrélation exacte avec l'état radiologique.
    Notizen: Summary Biplanar radiography was used to assess bony union after intertransverse fusion. The patients were assessed clinically and the fusion status was compared with the clinical result. Posterolateral intertransverse fusion was shown to be capable of fusing the motion segment almost completely. However, the strictly measured fusion rate was only 27%, but this increased to 91% when partial fusions were included. The fusion rate from conventional plain films assessed by the radiologist was 82%, which is similar to other reports. On clinical examination, a satisfactory result was obtained in 82%, but there was no clear correlation with fusion status.

    Notizen: Summary The cavernous sinuses of 17 patients examined by metrizamide CT cisternography with 1.5 mm-thick slices were reviewed. Most of the cavernous sinuses contained fatty components. Anterior lateral end and posterior end of the cavernous sinus are the common sites where the fat is visible.

    Notizen: Abstract Polystylene latex particles coated with serum albumin of various species, including non-primate serum albumin, were agglutinated by sera containing hepatitis B surface (HBs) antigen and hepatitis Be (HBe) antigen and by purified HBs antigen. Monomer and polymer albumin separated from human serum albumin preparations on latex particles were found to react with HBs antigen. Monomer from non-primate serum albumin preparations bound to latex particles was also found to have the ability to react with HBs antigen, but polymer of non-primate serum albumin did not. The mechanism of reaction between HBs antigen and the latex-bound serum albumin of various species is discussed.
