Friction stir lap welding (FSLW) between SPC270 steel sheet and A6061 aluminum alloy sheet were investigated with the effect of tilt angle and plunge depth of the welding tool. Tilt angle of 3 degree improved the material flow and suppressed generation of defect in the weld. The weld strength with tilt angle increased with the plunge depth of the welding tool and achieved maximum value of 212 MPa at 0.15 mm of plunge depth. From the TEM observation, uniform reaction layer of 450 nm was formed on the weld interface. On the weld interface, probe rotation and movement fabricated weld bead like structure on the steel surface and formed hook like structure on the cross section. Although the weld without tilt angle had a groove like defect, the weld strength was 208 MPa at 0.06mm of plunge depth. The weld interface was composed of laminated structures with different composition of aluminum and iron with 400 nm in each layer. This achieved by the mixing and pressurization by the probe on the weld interface.

With AKARI, we carried out near-infrared spectroscopy of the nearby barred spiral galaxy, NGC 1097, categorized as Seyfert 1 with a circumnuclear starburst ring. Our observations mapped the galactic center region. As a result, we obtain the spatial distributions of the polycyclic aromatic hydrocarbon $3.3{\mu}m$ and the aliphatic hydrocarbon $3.4-3.6{\mu}m$ emission. The former is detected from all the observed regions and the latter is enhanced near the bar connecting the ring with the nucleus. In addition, we detect absorption features due to $H_2O$ ice and CO/SiO at the ring and the galactic center, while we detect the hydrogen recombination line $Br{\alpha}$ only from the ring. Hence the observed spectra change dramatically within the central 1 kpc region.
