Dissimilar metals of 6022 aluminum alloy and galvannealed steel were joined successfully by laser brazing with new zinc brazing filler metal which was added Si. Si addition in the filler metal has great effects in preventing the growth of the IMC layer such as Fe2Al5 and minimizing its thickness. The peel strength of the joint with ZnSi filler metal increased by 3.5 times from that of joint with ZnAl filler metal. Fracture occurred at aluminum HAZ for joint with ZnSi filler metal and at brazing interface for joint with ZnAl filler metal. From TEM observation and diffraction analysis of brazing interface with ZnSi filler metal, Fe3Al2Si3 that had the same lattice spacing as α-Fe was observed. Thus, Fe3Al2Si3 that formed on the surface of steel prevented the formation of brittle intermetallic compound like Fe2Al5. © 2012, JAPAN WELDING SOCIETY. All rights reserved.

A manganese-based solid solution with the composition of Li 1.95Mn 0.9Co 0.15O 3 was synthesized by a simplified coprecipitation method, followed by a combustion technique, and its electrochemical characteristics as a lithium-battery cathode were investigated. Rietveld refinement based on neutron diffraction data revealed that the material is assigned to an Li 2MnO 3-type structure model with a monoclinic cell due to the space group symmetry of C2m. In cycling of the LiLiLi 1.95Mn 0.9Co 0.15O 3 cell in the potential range of 2.0-4.8 V at current densities of 30 mAg -1, the discharge capacity characteristically increases from 46.3 to 196.5 mAhg -1 as the cycle increases from 1 to 11, and a discharge capacity of >175.5 mAhg -1 is obtained between the 23rd and 58th cycles with small capacity fading of 2.41. The results of cyclic voltammogram (CV) and X-ray photoelectron spectroscopy (XPS) measurements showed that the manganese redox reaction (Mn 3+Mn 4+) in the Li 1.95Mn 0.9Co 0.15O 3 system is progressively activated during the first ten-odd cycles, following continuous occurrence of the extraction of oxygen molecules from the electrode material over these charge processes. It could be assumed that such behaviors significantly influence the electrochemical characteristics of the Li 1.95Mn 0.9Co 0.15O 3 system. © 2012 The Electrochemical Society.

A reduction of visceral fat is important for improvement of metabolic risk. This study was designed to compare the effects of a web-based program alone or together with measurement and self-awareness of accumulated visceral fat in Japanese workers. A new noninvasive device to measure visceral fat accumulation was introduced, and efficacy on weight-loss and improvement of healthy behaviors were examined. This study was conducted according to Helsinki declaration and approved by the ethical committee of Japan Hospital Organization, National Kyoto Hospital. Two-hundred and sixteen overweight and obese males with BMI of more than 23 participated from 8 healthcare offices of 3 Japanese private companies. Subjects were randomly allocated into control group, Web-based weight-loss program (Web), or Web + Visceral fat measurement group (Web + VFA). Eighty-one percent of participants completed the study. Reductions of body weight, waist circumference, and BMI were the largest in Web + VFA group, and the differences between groups were significant by ANOVA. Improvements of healthy behaviors were the largest in Web + VFA group, and the differences of healthy eating improvement scores between Web + VFA and control groups were significant. Our findings suggest that measurement and awareness of visceral fat are effective in weight reduction in overweight and obese males in the workplace.

We address the problem of 6D pose estimation of a textureless and shiny object from single-view 2D images, for a bin-picking task. For a textureless object like a mechanical part, conventional visual feature matching usually fails due to the absence of rich texture features. Hierarchical template matching assumes that few templates can cover all object appearances. However, the appearance of a shiny object largely depends on its pose and illumination. Furthermore, in a bin-picking task, we must cope with partial occlusions, shadows, and inter-reflections. © 2012 IEEE.

Blow forming accompanied with superplasticity makes possible the forming of complex parts, which cannot be formed by cold press forming. The conventional superplastic AA5083 alloy 'ALNOVI-1' developed by the Furukawa-Sky Aluminum Corp. shows high superplasticity because of its fine grain and is widely used for blow forming. However, for mass production of components, an Al-Mg alloy with finer-sized grains is needed. In this research, the newly developed high Mn version of the Al-Mg alloy 'ALNOVI-U' is used, and this material possesses grains finer than those of the conventional AA5083 alloy. The effects of finer grain size on the blow formability at high strain rates over 10-2/s and the properties of the resulting moldings were studied. © (2013) Trans Tech Publications, Switzerland.

A numerical analysis has been performed for a developing turbulent flow in a rotating U-bend of strong curvature with rib-roughened walls using an anisotropic turbulent model. In this calculation, an algebraic Reynolds stress model is used to precisely predict Reynolds stresses, and a boundary-fitted coordinate system is introduced as a method of coordinate transformation to set the exact boundary conditions along the complicated shape of U-bend with rib-roughened walls. Calculated results for mean velocity and Reynolds stresses are compared to the experimental data in order to validate the proposed numerical method and the algebraic Reynolds stress model. Although agreement is certainly not perfect in all details, the present method can predict characteristic velocity profiles and reproduce the separated flow generated near the outer wall, which is located just downstream of the curved duct. The Reynolds stresses predicted by the proposed turbulent model agree well with the experimental data, except in regions of flow separation. © 2010 Taylor & Francis.

MIG is a conventional one-sided welding technique. Although it is an effective technique for aluminium structures, which are increasingly adopted for use in pipes and cast components, the large variation in work accuracy resulting from the very large heat input can be a problem. To produce an all-aluminium body, a welding technology with low heat input and low deformation was developed through a hybrid technique that combines the use of a laser with MIG welding. The resulting hybrid welding process described in this report contributed to improved body accuracy. © 2013 Copyright Taylor and Francis Group, LLC.

The simplified one-step hydrothermal synthesis, in which SiO 2 is directly reacted with aqueous NaOH in the presence or absence of tetrapropylammonium bromide (TPABr) and tetrabutylammonium bromide (TBABr) as the template compound, was investigated. The reaction in the absence of the template compounds leads to the production of pure magadiite, whereas pure Si-ZSM-5 is produced by the reaction in the presence of TPABr. On the other hand, crystalline magadiite/Si-ZSM-11 composites are synthesized by the reaction in the presence of TBABr. Furthermore, for the composites, the particle sizes of the magadiite and Si-ZSM-11 may be influenced by the TBABr concentrations. It was also found that the compositions of magadiite and Si-ZSM-11 in the composites can be controlled by regulating the NaOH concentrations. © 2010 The American Ceramic Society.

During the planning of Honda's new plant in Ogawa Japan, which is the new benchmark for developed countries power train plants, there was a project requirement established for a significant reduction in initial investment. In order to improve the competitive edge of module machines, which is the foundation of Honda's existing powertrain machining lines, Honda targeted a reduction in the number of module machines through concurrent machining of multiple workpieces, and minimization of transfer time. By developing exclusive jigs for cylinder heads and blocks, this project was able to meet the original project reduction requirements. In addition, Honda was able to shorten the loading and unloading times of a module machine by developing an exclusive transfer machine specifically for cylinder heads.

Today, conventional requests for automation and modern requests for flexibility in handling product diversity and changes in production volume regarding assembly operation are increasing. In order to satisfy those, the "Innovative Automation Cell" (Refer to Figure 1) has been proposed as an innovative assembly production system in lieu of an assembly line operation, which has been continuing with the use of automatic conveyance. Furthermore, technical developments were implemented, such as "Real-time Position Attitude Correction Technology" and "High-speed Emergency Recovery System", as well as "Assembly Operation Support System", to make an easy system for an operator, so as to minimize reduction of run rate in mass production practices. This article addresses the concept of the "Innovative Automation Cell", the details of the developed technology, the effects of introduction to mass production, and future issues. Proposed concept is more than double in production efficiency compared to manual assembly. Copyright © 2015 SAE International.
