    Notes: Functions of interlinings to the shell fabric are to improve the garment formability for a beautiful silhouette and elastic potential to the deformed fabric during wearing, and also are to enhance appearance and wearing properties of the garment. The objective of this study is to analyse suitability of nonwoven fusible interlining to the thin worsted fabric with various fabric structural parameters. For the purpose of this study, specimens with various weft yarn twists and weft densities of thin worsted fabrics are prepared. Three nonwoven fusible interlinings with different structure which were made of nylon/polyester were used for adhering to the thin worsted fabrics. Mechanical properties of these 24 adhesive fabrics fused with three nonwoven interlinings are measured by the KES-FB System for analysing the suitability of nonwoven fusible interlinings to the thin worsted fabrics with various fabric structural parameters. Some mechanical properties of fused fabrics are analysed and discussed with repetition of dry cleaning of adhesive fabrics for performing effects of dry cleaning to the suitability of nonwoven fusible interlining to the shell fabrics.

    Adsorption of oxygen on the paramagnetic defect centers in aluminophosphate molecular sieves (1997)
    Springer

    Notes: Abstract Temperature-programmed desorption (TPD) and electron spin resonance (ESR) techniques have been employed to investigate the oxygen adsorbed on the paramagnetic defect centers in dehydroxylated AlPO4-20, AlPO4-11, AlPO4-5, and VPI-5 molecular sieves. Two different adsorption sites are observed for the small-pore AlPO4-20, where oxygen is entrapped within the intracrystalline voids generated during the calcination step, as well as within the β-cages. However, the unidimensional molecular sieves AlPO4-11, AlPO4-5, and VPI-5 have only one type of adsorption site within their inner pores. The apparent activation energies of desorption (12.0-21.7 kcal mol-1) determined from the oxygen TPD results demonstrate that, as the pore size of the AlPO4 molecular sieve is larger, the interaction between the adsorbed oxygen and the molecular sieve framework becomes weaker.

    Notes: Issues of ferroelectric high-density memories (〉64Mb) indispensable for upcoming ubiquitous era have been on the cell integration less than 0.1um2 and reliabilities. Thus nanoscale control of microstructures of ferroelectric films with large switching polarization has been one of the issues to obtain the uniform electrical properties for realization of high-density memories. In this study the grain orientations and distributions of BT-based films by spin-on coatings were examinedby EBSD (electron backscatter diffraction) technique. Ferroelectric domain characteristics by PFM (piezo-response force microscope) were also performed to study the dependence of reliabilities on the grain orientations and distributions. It is believed that understandings of the nucleation and growth mechanisms of the a- or b-axis oriented films during the thermal processes such as RTA and furnace annealing affecting on grain orientation and uniformity could be possible based on this experimental results

    Notes: The purpose of this study was to investigate the effect of vibration device in gas transferrate for usage as intravenous lung assist device. Specific attention was focused on the effect ofmembrane vibration. Quantitative experimental measurements were performed to evaluate theperformance of the device, and to identify membrane vibration dependence on hemolysis. Scalinganalysis was then used to infer the dimensionless groups that correlate the performance of avibrated hollow tube membrane oxygenator. The experimental design and procedure are then givenfor a device for assessing the effectiveness of membrane vibrations. This ILAD is used to providesome insight into how wall vibrations might enhance the performance of an intravascular lung assistdevice. The time and the frequency response of PVDF sensor were investigated through variousfrequencies in the ILAD. In these devices, the flow of blood and the source of oxygen wereseparated by a semipermeable membrane allows oxygen to diffuse into and out of the f1uid,respectively. The results of experiments have shown vibrating ILAD performs effectively

    Notes: The micromanipulator is basically required sufficient workspace and high naturalfrequency. However, previous designs are hard to satisfy the required workspace and naturalfrequency simultaneously. In this study, a previous design was analyzed from the viewpoint of theaxiomatic design. Then, a new design parameter as displacement amplifier which transforms acoupled design into a decoupled design, was suggested. And a design procedure based on axiomaticdesign was developed. A spatial 3-DOF parallel-type micromanipulator was chosen as an exemplarydevice. According to the suggested design procedure, the micromanipulator having the requirednatural frequency was designed in the first step, and then the displacement amplifier satisfying therequired work space was designed sequentially. To check the effectiveness of the manipulator anddisplacement amplifier, simulations and experiments were performed. Those are verified that thedisplacement amplifiers implemened work very well for satisfying the required task workspace

    Notes: The effectiveness of the visual feedback to improve ability with the sense and muscularstrength of human in our bicycle system was quantitatively verified in our study. Experiments wereperformed to find the factors related to the training of equilibrium sense. The subjects consisted ofyoung and the aged and the group of young people was compared against the group of the aged. Weinvestigated three different training modes, non-visual feedback (NVF), visual feedback of theweight (VFW), and visual feedback of the center of pressure (VFC) and measured the riding timeand speed, the weight shift, and the center of pressure (COP) for twenties and seventies. The resultsshowed that the running capability of the young and the aged became much better after repeatedtraining. In addition, it was found out that the ability to control postural balance and the capabilityof equilibrium sense were improved with the presentation of the visual feedback information. Theseresults will be effective in the diagnosis of equilibrium sense and vestibular function with the aged

    Notes: The purpose of this study is to estimate structural characteristic for air inlet part of ramjet in condition of flight at 12-15km height. Because air inlet part of ramjet is heated up to 700oK, high temperature properties such as Young’s modulus, thermal expansion coefficients and thermal conductivity coefficients are applied to the analysis. The analysis of transient temperature and thermal stress was performed by the finite element method with nonlinear code ABAQUS. The analysis was performed using several thermal coefficient and material properties to select preliminary design model for flight condition. Thermal boundary conditions were applied at ramjet inlet part until 0.01sec. The results of the analysis recommend tendency of thermal stress and temperature distribution. These are useful to select the structural material and to determine shape of air inlet part which satisfy the structural design safety

    Notes: We have investigated the field limiting ring (FLR) geometry dependence of breakdownvoltage characteristics for a junction barrier Schottky (JBS)-assisted FLR SiC-SBD. The SiC-SBDshaving a guard ring-assisted FLR surrounding a Schottky contact edge and an internal ring insideSchottky contact were fabricated. The breakdown voltage characteristics of the JBS-assisted FLRSiC-SBD are significantly dependent on the width, spacing, and number of FLR. The breakdownvoltage characteristic is improved as either the FLR width and FLR number increase or the FLRspacing decreases. Approximately 1650 V maximal breakdown voltage, corresponding to 82% idealbreakdown voltage, is observed with seven FLRs having 5 2m width and 1 2m spacing
