    Notes: Magnetic and other properties of Co-base amorphous alloy films prepared by sputtering are investigated. A detailed magnetic phase diagram with saturation magnetic flux density, crystallization temperature, and zero-magnetostrictive line on Co-Ta-Zr amorphous alloys were obtained, and the technical knowhow to make a film with well-reproducible characteristics by widely changing the sputtering conditions was related with these physical properties. Especially on alloy sputtering, a phenomenological model for elucidating a composition difference between film and target is presented. After these studies, the film characteristics of Bs=12 kG, Tx=450 °C, ||λs||〈10−8, Hc〈10 mOe, and permeabilities of μ(1 MHz)=7000, μ(100 MHz)=2000 for the single film of 2 μm in thickness and of μ(1 MHz)=4000, μ(100 MHz)=800 for the insulator-sandwiched multilayered film of 10 μm are obtained, and these well-balanced values enable us to apply the materials for high-frequency recording head.

    New crystalline soft magnetic alloy with high saturation magnetization (invited) (1987)
    [S.l.] : American Institute of Physics (AIP)

    Notes: Extensive study was made on Fe-base crystalline alloys in search for new soft magnetic materials with high saturation magnetization by means of sputtering technique. It revealed that newly found FeGaSi and FeAlGe alloy systems possessed excellent soft magnetic properties with remarkably higher saturation magnetization. These new alloy films, annealed in vacuum at 500 °C for 1 h, show the magnetic properties of Bs=13 and 15 kG, Hc=0.09 and 0.20 Oe, and μ1 MHz=2000 and 1800 for the FeGaSi and FeAlGe alloy films of 2 μm in thickness, respectively. These values are superior to those of FeAlSi (sendust) alloy which is a typical soft magnetic material with high saturation magnetization. Results of the Co-added systems of FeCoGaSi and FeCoAlGe alloys are also presented. Discussions are given on various systems of Fe base crystalline alloy films studied, which are classified into four types of groups with respect to magnetic softness.

    Vascular compromise in chronic volvulus with midgut malrotation (1987)
    Springer
    Pediatric radiology 17 (1987), S. 277-281

    Notes: Abstract Three cases of chronic volvulus of the small bowel in midgut malrotation are presented, all of whom manifested similar angiographic findings: proximal occlusion of the superior mesenteric artery and vein and development of collateral vessels. These findings may indicate the pathophysiology of chronic volvulus in midgut malrotation; the volvulus is progressive and eventually results in the twisting of the mesenteric root itself, but because of its chronic nature collateral circulation develops, eliminating bowel necrosis. Computed tomography (CT), performed in two cases, revealed dilated, tortuous vessels in the mesentery in addition to the known CT finding of a whirl-like pattern of the volvulated small bowel loops. Sonography, performed in one case, showed an unique feature of whirling sonolucent layers probably representing the volvulated small bowel loops intermixed with dilated mesenteric collateral vessels. We would like to emphasize the usefulness of CT and sonography in the early diagnosis of those cases with vague and nonspecific clinical manifestations.

    The effect of the dw gene on the muscle protein turnover rate in chickens (1987)
    Springer
    Biochemical genetics 25 (1987), S. 253-258

    ISSN: 1573-4927

    Notes: Abstract Fractional rates (%/day) of muscle protein synthesis and degradation of the genotypes Dw/Dw and dw/dw of male White Plymouth Rock chickens were determined by measuring the output of Nτ-methylhistidine (Nτ-MH) in the excreta at 2, 4, and 8 weeks of age. The fractional growth rate of dw/dw was significantly lower (P〈0.05) than that of Dw/Dw at 2 weeks of age but not at 4 and 8 weeks of age. No significant differences in the degradation rate (K d; %/day) were found at any age. A significant difference (P〈0.05) between genotypes in the rate of synthesis (K s; %/day) was found at 2 weeks of age (Dw/Dw=11.8, dw/dw=9.9) but not at 4 and 8 weeks of age. These results suggest that the dw gene has a depressing effect on the synthesis rate of muscle protein, and the difference between genotypes in the growth rate at the early stage is a reflection of this effect.

    Photosensitive resins containing p-dimethylaminobenzylidene derivatives and diphenyliodonium salt as photoinitiators (1987)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: A series of p-dimethylaminobenzylidene derivatives was able to sensitize the photodecomposition of diphenyliodonium salt to afford highly photosensitive negative-type resins. When a polymer-bearing methacryloylated group in the side chain was sensitized with a combination of the p-dimethylaminobenzylidene compounds and the iodonium salt, the polymer demonstrated high sensitivity even to 488 nm light emitted from an Argon laser. The same photoinitiator systems were applicable to insolubilize poly(glycidyl methacrylate) through cationic photopolymerization. The storage stability of these types of photoinitiators depends on the structure of the benzylidene compounds; decreasing the basicity of the amino group enhanced the thermal stability.
