 * Type B Past Week Summary
  * Fabian, Mark and Liu-kun did BS installation at Kamioka:
   * Built up the security structure to the ring below the BF.
   * Adjusted the crossbeams below the BF and installed the jacks and pushrods to support the BF.
   * Craned in the BF.
   * Hung the top plate of the IRM.
   * Practiced hooking the BF-IM maraging rod (by lowering the BF with the jacks) - success. Need to redo with hexagon cable clamp.
   * Took TFs from L, P and actuation at the RM to all DOFs at the BS.
  * Hirata-san:
   * Made 3D models of (revised) stub flag gluing jigs.
   * (For other groups)
    * Assembled two BFs.
    * Made drawings of PRM inner frame.
  * Mark checked lots of drawings by Hirata-san.
  * Mark worked on schedule.
  * Mark added the DIO card to a draft of the BS electronics diagram, D1503600. At first it appeared that the pinouts of the LPCD DIO connectors were completely incompatible with the DIO card cables, but it turns out (according to Miyakawa) that the LPCD chassis has a secret interface board (JGW-D1504332) not shown in the chassis drawing which should make everything work.
 * Longer term to-do list
  * Do Inventor assembly for SRx in chamber and on assembly frame (Hirata) - SR2/SR3 DONE, SRM ongoing.
   * Part "disk security" top has to be modified - screw positions do not match.
  * Write more of payload assembly procedure (Fabian) - ONGOING
  * Write more of BS Assembly Procedure [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=4235| E1504235]], [[https://onedrive.live.com/redir?resid=D5CCFA70A378E0D0!195&authkey=!AM_usynuo9QI57g&ithint=folder,webloc|E1504235 draft]] (Mark) - ONGOING
  * Lower breadboard installation to be incorporated into the procedure document.
  * Work on BS simulation (Fabian)
  * Do BS Simulink model (Mark, Kokeyama) - TM/IM/BF level DONE
  * Do 2D drawings of SR2 parts (Hirata)
  * Redesign SRx IM wire clamps for larger prisms, remachined RMs
  * Order SRM/PRM parts (Hirata/Shoda)
  * Order SRx fasteners (Hirata)		 === Type B (Mark) ===
==== Past week report ====
At Kamioka (Mark, Fabian, Hirata-san, Yoshioka-kun):
 * We reconfigured the top of the assembly frame.
 * We cleaned the assembly frame, blowing dust out of the grooves and wiping all surfaces.
 * We recentered the optic table in the bottom of the frame and adjusted the frame until the top was centered over the optic table. We also recentered the trolleys.
 * We re-installed, centered and leveled the IM.
 * We solved two issues with the new wire clamps:
  * Some holes were not properly threaded - Hirata-san retapped them.
  * Some locating pins were loose - we glued them.
 * We mounted the BS mirror box on the trolley and brought it under the IM.
 * We installed the winch system and the 300 µm wires for the BS.
 * We set up the optical lever.
 * Hirata-san finished the new BF. We moved the old BF out of the cleanbooth and the new one in.
 * We suspended the BS and set its height and pitch.
