 * Type B Past Week Summary
  * 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.		 === Type B (Mark) ===
