    Notes: A novel ridge waveguide laser diode has been developed in which the ridge is buried in a newly developed polyimide with a low thermal expansion coefficient close to that of AlGaAs which reduces the thermal stress to the junction and simplifies the wafer processing. A planar configuration, which is suitable for optoelectronic integration and an episide down mount for high-power operation, has been achieved by an etch-back process. Under cw operation, a low threshold current of 15 mA at 25 °C, a characteristic temperature T0 of 145 K, and maximum power output higher than 30 mW/facet have been obtained in a molecular-beam-epitaxial-grown graded-index separate confinement heterostructure single-quantum-well laser emitting at 780 nm.

    Notes: A new seed structure, partially thickened silicon films on insulator (PTS), is proposed for multilevel seeded-laterally epitaxial silicon films on insulator (SOI). Two-level seeded-laterally epitaxial silicon films on thick SiO2 (2.5 μm) were successfully fabricated, using the PTS structure in conjunction with the electron-beam technique. The SOI surface flatness after recrystallization was also improved by the PTS. Through computer simulation of the electron-beam recrystallization process, it is determined that the PTS structure enhances the lateral heat conduction within the SOI. This is important in smoothly melting the seed and field SOI regions.

    Notes: A new electron-beam annealing technique, an amplitude modulated pseudoline electron beam, has been proposed for recrystallization of large-area silicon layers on insulating materials (SOI). The technique utilizes an amplitude modulated sinusoidal wave for high-frequency beam oscillation. Through computer simulation of the temperature distribution for the sample surface, precise control of the position probability density profile of the line beam proved to be essential in realizing wide and uniform annealing. An optimum oscillation waveform was determined from the simulation. A large-area SOI, 4 mm (D'Alembertian), was successfully recrystallized.

    Development of a large volume negative-ion source for ITER neutral beam injector : Papers from the Ninth International Conference on Ion Sources (2002)

    Notes: Development of the negative-ion sources has been conducted to realize a high power neutral beam injector for International Thermonuclear Experimental Reactor (ITER). A high negative-ion current density of 31 mA/cm2 (H−) at a very low pressure of 0.1 Pa has been produced in a cesium seeded multicusp plasma generator which has the same concept of the ITER source. For a vacuum insulated accelerator, a voltage holding experiment of long distance vacuum gaps up to ∼1.8 m has been performed. It was clarified that the transition region of product pressure distance (pd) from the vacuum breakdown to the gas discharge is about 0.2 Pa m which is high enough from the operating region of the ITER source. A prototype vacuum insulated accelerator was fabricated based on the experiment and tested. A high-energy H− beam acceleration up to 970 keV, 37 mA, and 1 s has been successfully demonstrated. © 2002 American Institute of Physics.

    Neutral beams for the International Thermonuclear Experimental Reactor : The 8th international conference on ion sources (2000)

    Notes: Receiving higher emphasis on the neutral beam (NB) off-axis current drive, the NB system is being highlighted for the steady state operation of the International Thermonuclear Experimental Reactor (ITER). To fulfill the physics requirement of heating and current drive, the NB system delivers ∼50 MW of D0 beams at 1 MeV into the ITER plasmas. The NB injector was designed so as to minimize the axial length, to avoid cost impact on the building. It was estimated by nuclear analyses that the insulation gas around the beam source would cause radiation induced conductivity, which would result in a power dissipation of 〉100 kW in the gas itself. As a result the present design utilizes vacuum insulation around the beam source. Since the vacuum pressure inside/outside the beam source ranges 10−1–10−2 Pa, both gas (glow) and vacuum arc discharges are taken into account in the design. © 2000 American Institute of Physics.

    Notes: The purpose of this study was to investigate the vibratory characteristics of three designs of the Class I Kennedy maxillary removable partial denture frameworks as the basic study. Their major connectors comprised a U-shaped palatal connector (UPC), single palatal bar (SPB), and anterior–posterior palatal bars (APB). Frequency response functions were measured when the framework was impacted. The modal shape was observed and the decay rate was calculated using modal analysis software. The results showed that the vibratory properties of each framework differed from each other. Within the range of frequencies from 10 to 2000 Hz, the UPC type had seven natural frequencies, while the SPB and the APB types had six. The UPC type had a greater number of natural modes accompanied by elastic deformation, including fluttering and twisting, than the other type, and the UPC type was considered to be unfavourable. The decay rate of the APB type was significantly higher than those of the UPC and the SPB types (P 〈 0·01).

    Notes: In order to establish an objective method of evaluating ladies' garment fabrics by connecting the mechanical properties of ladies' garment fabrics to subjective evaluation, subjective assessments were examined by judges who work at textile mills or in the textile trade. We examined a method of deriving objective equations, a total hand value (THV) equation and a total appearance value (TAV) equation. The THV equation was derived directly from the mechanical properties of the fabrics and the TAV equation was derived from three mechanical parameters which are related to the beauty of garment appearance. In the case of the THV objective equation, the accuracy of regression was high within the same groups of judges; however, in the case of the TAV objective equation, accuracy was slightly low. Because there were few subjects and that caused deviation, the accuracy of prediction was slightly low; however, the objective evaluation was adequate.

    Notes: Abstract This report describes a dot enzyme-linked immunosorbent assay (Dot-ELISA) for detecting circulating antigens in the sera of dogs infected with Dirofilaria immitis (D. immitis). Circulating D. immitis antigens could be detected in 24 of 25 infected dogs. The remaining animal had two immature worms. However, non-infected dogs and dogs infected with other parasites were all negative, Few cross-reactions to different parasite antigens were observed. The advantages of the Dot-ELISA include; 1) there is no need for pretreatment and dilution of sera and samples could be immediately bound to nitrocellulose paper set into microfiltration apparatus, 2) this assay could be carried out within 2 h at room temperature, 3) the resulting enzyme-reaction could be measured by both visual observation and densitometric reading.

    Immunological evidence for two types of PQQ-dependent d-glucose dehydrogenase in bacterial membranes and the location of the enzyme in Escherichia coli (1986)

    Notes: Abstract Using an antibody raised against d-glucose dehydrogenase (EC 1.1.99.17) purified from Pseudomonas fluorescens, immuno-cross-reactivity with the enzymes from several bacterial strains and localization of the enzyme in Escherichia coli were examined. The antibody cross-reacted with glucose dehydrogenases from various Gram-negative bacteria examined. As a result, it became apparent that the enzymes from Gluconobacter, Acetobacter, Pseudomonas and Acinetobacter, which existed as holoenzymes in the membranes, had lower molecular weights than those from E. coli and Klebsiella, which were apoenzymes.Treatment with trypsin of right-side out and inside-out membrane vesicles from E. coli clearly demonstrated that d-glucose dehydrogenase was located on the outer surface of the cytoplasmic membrane of E. coli, as had been suggested for Pseudomonas.

    Induction of cartilage and bone by dentin demineralized in citric acid (1986)

    Notes: The capacity of a roll of dentin demineralized by either 0.6N HCl, pH 1 for 3 minutes or 3 hours, or by 3M (9N) citric acid, pH 1, for 3 minutes, to induce cartilage and bone when implanted in muscle, was investigated. Serial sections of specimens were examined 7, 10, 14. 17, and 21 days after implantation, and randomly selected sections analyzed histomorphometrically. Cartilage was induced on the internal aspect of the citric acid-demineralized dentin roll, but significantly less than that induced after demineralization with HCl. The quantity of bone deposited subsequently did not significantly exceed the amount of cartilage that preceded it in relation to any of the preparations used. The results suggest that citric acid-demineralized dentin induces chondrogenesis and osteogenesis when implanted in muscle, but does so less effectively than does HCl-demineralized dentin, and only within the confines of a microenvironment. It is therefore unlikely that citric acid demineralization of root surface results in induction of cementum by this mechanism.
