 * Type B Past Week Summary
  * Mark and Fabian worked at Kamioka:
   * All the parts for the security structure were located. The clamp pieces for the IM are being taken back to Mitaka to have extra screw holes added.
   * The BS/PR2/SR2 area was cleaned and tidied to allow floor removal and assembly frame construction.
   * 21 "Type 1" cables (PI-Flange, Signal) and 15 "Type 5" cables (OSEM) were tested. They all passed. Sufficient tested "Type 2" cables (PI-Flange, Motor) were located in the PR3 area.
   * Hirata-san worked on the Inventor assembly, adding views (originally defined by Mark) of the different phases of construction.
   * Hirata-san shipped 7 SFs and some parts to Kamioka.
   * Hirata-san made assembly drawings of the damper rings and cable clamps for SR.
   * Hirata-san liaised with Mirapro about the frame assembly.
 * Type B ongoing issues
  * Wires
   * Need to decide RM wire thickness and order BS and RM wires. Lead time is a few days from Nilaco.
  * OSEMs
   * Akutsu-san is working to get wide-mouth OSEMs
  * Longer cables for BF->PI and SF->PI.
   * Takahashi-san has ordered extra connectors (due any day) and will get a company to make the cables.
  * Feedthrough Adapters
   * Need large quantity of male and female D-Sub 9, IDC ribbon connectors - Takahashi-san is getting a quote.
  * Can we make SR wire breakers bigger?
   * Fukushima-san will start on machining test soon (as of 5/27).
  * Installation stuff
   * Crane scale - RECEIVED
  * Ballast masses for payload
   * Initial batch received - ordered extra smaller ones to allow for adjustments.
  * Lower breadboard stuff
   * Installation to be incorporated into the procedure document. Mark/Takahashi to discuss.
   * Breadboard springs (in manufacture, expected end of July)
   * Nail-head parts: quote from Mirapro received, not urgent, will be combined with assembly frame order.
  * Documents
   * 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]]
