Multi-Point Die Support System for Large Deep Drawings: Development of Manufacturing Technology Endowed with a High Affinity to Information Technology
Abstract: Numerical analysis systems such as FEM have been utilized successfully for predicting accuracy and defects of a product in metal forming; however, they have limitations of ability dealing with the problem due to uncertainty of the actual condition. An analysis model seems to be doomed to never meet for it because of the machine difference and uncertainty of the motion and shape of a tool depending on the play and elastic deformation of a manufacturing machine. For instance, dies of large deep drawings tend to be easy to deform elastically during the process and it is affected by the die-setup and the machine difference (i.e. difference of rigidity of the machine and floor, motion of the slide and reaction of the cushion), therefore, actual contact condition between a die and a press tend to be different form the numerical model. Today, automobile manufacturers are aim to improve design quality of dies with employing information technology (IT) including numerical analysis, and to speed up the design for so-called no trial manufacture; however the above problem is a crucial barrier to it. The author have proposed development of manufacturing technology(MT) endowed with a high affinity to numerical analysis and other information technology(IT) as one of possible solutions for it. For large deep drawing, the author developed the multi-point die support system that supports a die with multiple points with embedded load sensors. The system supports the die more stable than with normal surface support of the die, and provides information about the contact condition between the die and the machine in the process. The author utilized the information for the analysis of elastic deformation of dies for deep drawing for the panels of automobiles in the actual condition. In addition, the author tried to control the surface accuracy of the products by changing the distribution of support points with regarding the information or inserting semi-active controlled support units under the support points.

Application of TRC High Aluminum Content Magnesium Alloys for Hot Forging
Possibilities of hot forging of high
aluminum content magnesium alloys sheets manufactured by horizontal twin-roll
casting process have been discussed. Mg-11%Al-1%Zn, Mg-12%Al-1%Zn and
Mg-13%Al-1%Zn which contains relatively high aluminum content magnesium alloys
were applied for twin-roll casting, and a hot forging test was performed to
manufacture high strength magnesium alloy components economically. In twin-roll
casting, casting condition for thick sheet for hot forging was investigated. It
has been found that twin-roll casting of about 10 mm thick magnesium alloy sheet
was possible at a roll speed of 2.5 m/min. The grain size of cast strip was
about 50 to 70
Biography: Hisaki Watari has received his PhD in Mechanical System Engineering, from Gunma University, Japan in 2006. He has been researching into properties of magnesium alloy by rapid cooling by using twin roll casting in these fifteen years in Gunma University and Oyama National Colleague of Technology in Japan, in UMIST in the UK. He is now the chair of the Japan Association of Aluminum Forging Technology. He has published more than 130 papers in journals and conducting works relating metal forming of light metals, such as aluminum and magnesium alloys.

Nanostructured Material for Optical Gas Sensing Devices
Abstract: The accurate detection of gases using their optical properties is highly important in industrial, and environmental applications. The optical detection technique is considered as one of the accurate technique for gas detection and has advanced very rapidly due to rapid progress in detectors and light sources. Basically in optical methods, the optical absorption and scattering of gas at certain wavelength are measured. The distribution of absorption with wavelength provide information on the nature of gas and its concentration. This presentation will review some recent development of optical gas sensors, starting with detection material such as metal oxide nanowires and nanorods that have been synthesized by varieties of techniques such as vacuum evaporation, laser ablation, magnetron sputtering and sol-gel and spectroscopy system. The presentation also includes some of our recent results in using ZnO nanorod for carbon monoxide gas detection.
Keywords: Metal oxide; ZnO; exciton; nanowires; nanorods; gas sensor; sol-gel,carbon monoxide.

Wonderful work with wood
Abstract: In this study wood polymer composite (WPC) were characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), thermo-gravimetric analysis (TGA) 3-point bending test, free-free-vibration. FTIR result showed that WPCs had more than one carbonyl absorbance band between 1745 and 1690 cm-1. The crystallinity index from XRD (CIXRD) varied for various WPC compared with raw wood. The SEM micrograph of WPC had smoother surface compared with raw wood. The modulus of elasticity (MOE), modulus of rupture (MOR), and dynamic Young's modulus (Ed) of WPCs were higher than raw wood. The raw wood exhibited a higher water uptake compared with WPC. The TGA results showed that WPCs were thermally less stable between 267 and 400 ºC than raw wood.
Key words: WPC, MOR,MOE, TGA, XRD, SEM.
