  The development of gaseous detectors has been exciting again since the
appearance of a MicroStrip Gas Chamber(MSGC) in 1988, which is made using a
micro-electronics technology. These days lots of variations of the advanced
gaseous detectors are being intensively studied in the world.
  We have developed the two-dimensional MSGC having a 10 cm square detection
area and the ultra fast readout system for a real time X-ray imaging. The MSGC
was made using Multi-Chip Module (MCM) technology, and has a very thin
substrate of 17 $\mu$m, lots of thin anodes and back strips both with 200
$\mu$m pitches. This enables us to get fast digital X-ray images with recording
both the timing and an energy of each X-ray photon. In addition, an
intermediate gas multiplier has been realized using a capillary plate having a
conductive surface of a capillary. The MSGC combined with the conductive
capillary plate can be steadily operated with a high gain under intense
irradiation. Here we also report new approaches of X-ray crystal structure
analyses using timing information obtained by the MSGC.
