We present an overview of the cryogenic system of the next-generation infrared observatory mission SPICA. One of the most critical requirements for the SPICA mission is to cool the whole science equipment, including the 2.5 m telescope, to below 8...

ZrB_2-SiC-ZrC (ZSZ), which is known as one of ultra high temperature ceramics (UHTCs) composite material, with four different compositions containing 16 vol.%SiC and ZrB_2-16 vol.%SiC were sintered by spark plasma sintering. These sintered compact...
Ultra thin fiber reinforced plastic plates, with around l0μm thickness, were fabricated using the uni-directionally aligned carbon nanotube (CNT) sheet. The CNT sheets are drawn wound around the bobbin from the CNT array developed on the silica gl...
