Type B Past Week Summary
- Mark and Hirata-san at Mitaka
  - Gathered parts for cable making.
- Mark and Hirata-san at Kamioka:
  - Replaced the floor panels that had been taken from the PR2 area (filling in the hole in the floor) and found/installed two new panels to act as bridges near the BS assembly frame.
  - Installed two more LPCDs and the stepper motor driver in the PR2 rack.
  - Ran cables from the rack to the second and third sat amps (for the IRM OSEMs).
  - Added a second DIO card in the rack and connected it to the BIO inputs and outputs of the new LPCDs.
  - Started making extension cables for RM-H2 and -H3 OSEMs but gave up due to complicated grounding arrangement.
  - Washed four 40-cm D-Sub-9 ribbon cables to use as temporary extensions (maybe also for H1/H4).
  - Added extension to the IM pico cable for the BF yaw pico.
  - Made LVDT adapter cable.
- Mark worked on schedule.

 Line 6:
-  * Mark 
   * Updated the BS circuit diagram [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=3600|D1503600]]:
    * Added information on the binary IO.
    * Renamed channels to conform to Okutomi-kun's new scheme.
    * Made the ADC/DAC channel assignment consistent and more logical.
    * Updated the stepper motor sections with info about the new driver chassis.
   * Worked on schedule.
   * Updated the installation procedure with lessons learned from the last few weeks.
   * Downloaded Hirata-san's Inventor model of the BS in the tank and starting thinking about installation of the suspension and lower bread board.
   * Mark and Hirata-san worked on collecting parts and tools that will be needed for cabling of the BS next week. (11 special-purpose cables need to be made for the picos/steppers/OSEMs/LVDT on the RM/IRM/IM/BF and, time permitting, 2 more for the SF.)
  * Hirata-san
   * Updated the BS 3D Assembly with the new rods and receptacles.
   * Made 2D drawings of SR2 and SR3 (ongoing).
   * Made SRM 3D assembly (ongoing)
   * Asked for and got quotes for hexagon cable clamps. Takahashi-san ordered the PEEK components. Next week Hirata-san will look for parts that should already be at Kamioka. 
   * Washed screws for hexagon cable clamps and shim rings for Fabian.
+  * Mark and Hirata-san at Mitaka
