    New measuring system for the distribution of a magnetic force by using an optical fiber (1993)

    Notizen: A new measuring system using an optical fiber and a position sensing photodetector was developed to measure a three-dimensional distribution of a magnetic force. A steel ball attached to a cantilever made of an optical fiber generated force in a magnetic field. The displacement of the ball due to the force was detected by a position-sensing photodetector with the capability of detecting two-directional coordinates of the position. By scanning the sensing system in a magnetic field, we obtained distributions of two-directional component of the magnetic force vector. The component represents the gradient of a squared magnetic field. The usefulness of the system for measuring the magnetic field distribution in a narrow clearance and for evaluating superconducting machine components such as magnetic bearings was verified experimentally.

    Optical and electrical properties of Ag-As-S glasses (1995)

    Notizen: Physical properties of Ag2S-As2S3 glassy alloys have been studied as a function of the Ag atomic concentration x. With an increase in x, the optical-absorption edge exhibits a red shift, while the steepness of the Urbach tail changes little. In the glasses with x≥15, the electrical conductivity is governed by Ag+ ionic conduction. The ionic conductivity exponentially increases with x, and in contrast the hole conductivity hardly changes with x; however, the activation energies for the ionic and the hole conductivity are nearly the same at about 0.4 eV for compositions with 15 ≤x≤35. These observations are discussed on the basis of atomic and electronic structures in Ag2S-As2S3 glasses. © 1995 American Institute of Physics.

    Photoelectric properties of Ag–As–S glasses (1995)

    Thema: Physik
    Notizen: Photoconductive and photovoltaic responses in glassy Ag–As–S ion-conducting semiconductors have been studied. The ac conductivity of the glass increases with illumination, while the increase is ascribed to enhanced ionic conduction caused by temperature rise and to interfacial photoeffects. Bulk photocurrent is not detected. By contrast, photovoltages appear in Ag–As–S samples having sandwich and floating electrodes. The photovoltaic characteristics are discussed in terms of classical electrodynamics assuming interaction between electronic carriers and Ag+ ions. © 1995 American Institute of Physics.

    High-rate growth at low temperatures by free-jet molecular flow: Surface-reaction film-formation technology (1988)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 52 (1988), S. 1173-1175

    Thema: Physik
    Notizen: Surface-reaction film-formation technology of epitaxial Si and polcrystalline silicon using free-jet molecular flow is proposed. High-rate (∼0.5 μm/min or higher) growth of homoepitaxial Si films with high crystallographic perfection has been achieved at temperatures as low as 600 °C without the chemical by-product deposition on the inner surface of the reaction chamber. This result also implies that this system has the cleaning-free function. The film-formation mechanism appears to be dominated by the chemical reaction on the substrate surface without the vapor phase reaction.

    Measurement of superconducting characteristics of high Tc materials by the magnetic force sensing system (1993)
    [S.l.] : American Institute of Physics (AIP)
    Review of Scientific Instruments 64 (1993), S. 1049-1052

    Notizen: A magnetic force sensing system using a highly sensitive force sensor was developed to measure the two-dimensional distribution of superconducting properties of high Tc materials. A probing tip made of a small piece of magnetized material was mounted on a cantilever scanned over superconducting surfaces. Magnetic properties of the superconductor generated force on the tip and the force was measured by an optical displacement sensor. Two kinds of YBCO superconductor were examined by the measuring system in order to compare their repulsive force and shielding characteristics. Two-dimensional distribution of repulsive force due to the Meissner effect of YBCO, which was fabricated by the melt powder melt growth (MPMG) process, showed evident nonuniformity which is attributed to the nonuniformity of chemical composition of the material. Although the MPMG materials are capable to be used as a magnetic shield, they have much larger residual flux than the materials fabricated by the solid phase reaction process.

    NbN/TiNx/NbN/TiNx/NbN double-barrier junction arrays for programmable voltage standards (2002)

    Thema: Physik
    Notizen: A series array of NbN/TiNx/NbN/TiNx/NbN double-barrier junctions was fabricated on Si wafers, and their current–voltage (I–V) characteristics were measured with and without microwave power in order to investigate their performance for programmable voltage standards. By adjusting the thickness of the TiNx barrier, nearly identical critical currents were obtained for 128 lower and 128 upper junctions in an array. When applying 8 GHz microwave power to an array, a large constant-voltage step (∼3 mA) appeared on the I–V curve. The zero-voltage critical current and the height of the first (n=1) constant-voltage step showed microwave-power dependences coincident with theoretical prediction. © 2002 American Institute of Physics.

    New findings in pharmacological effects induced by antihistamines: from PET studies to knock-out mice (1999)
    Oxford BSL : Blackwell Science Ltd
    Clinical & experimental allergy 29 (1999), S. 0

    Thema: Medizin
    Notizen: Antihistamines are efficacious drugs to be used for the symptomatic relief of allergic diseases. The safety issue of antihistamines is of central importance because of their widespread use in current medical practice. To better understand the pharmacological effects of antihistamines on the central nervous system (CNS), we used two kinds of new methods, positron emission tomography (PET) and gene targeting regarding on histamine H1 receptors. The histamine H1 receptor occupancy was examined in young male volunteers with[11C]-doxepin (a potent H1 antagonist) after the oral or intravenous administration of antihistamines. In other studies, the cognitive performance was also measured tachistoscopically before and after taking antihistamines. The mutant mice lacking H1 receptors were used in the behavioural and neurochemical experiments to re-evaluate the role of H1 receptors. The H1-receptor occupancy in the human frontal cortex caused by antihistamines is significantly correlated with the reported values of incidence of sleepiness in clinical trials, and the occupancy is well proportional to the impaired cognitive performance. The behavioural studies of the H1-receptor knock-out mice confirmed the role of H1 receptors in arousal, the sleep–wake cycle, locomotion, nociception and aggressive behaviour. The pharmacological effects induced by H1 antagonism were re-evaluated by the PET and gene-targetting. Although any serious effects could not be observed in mice by the destruction of the H1-receptor gene, the cognitive performance was impaired in humans after taking first generation antihistamines in recommended doses.

    Antihypertensive Activities of Peptides Derived from Porcine Skeletal Muscle Myosin in Spontaneously Hypertensive Rats (2002)

    Notizen: : Antihypertensive activities derived from porcine skeletal muscle proteins were investigated. Thermolysin hydrolysates of porcine muscle water-insoluble proteins demonstrated antihypertensive activities in spontaneously hypertensive rats when administrated in single oral doses. Hydrolysates of porcine myosin and peptides (Met-Asn-Pro-Pro-Lys, Ile-Thr-Thr-Asn-Pro, Met-Asn-Pro, Pro-Pro-Lys) with parts of the sequence of myosin showed antihypertensive activities. This is the first report of antihypertensive activities of peptides derived from muscle proteins of domestic animals. The hydrolysates of porcine muscle protein and their corresponding bioactive peptides might be utilized for physiologically functional foods.
