 * Put a report here  * Modification
  * The design is basically fixed. Checking is ongoing. (Saito, Shoda)
  * The structural analysis by Obuchi-san is being summarized. (Shoda)
  * The 1st cost estimation is sent from a company. Our order will be a open quatation.(Shoda)
  * Specsheet is almost ready (except for the updates on the parts list). (Shoda)
  * We will ask the cost estimate again with the additional parts and the proper form. (Shoda)
    IM flags, IM ballast masses, and correts will be ordered together with the modification parts.

 * Additional ordering for PRs.
  * additional masses for BF: the old IM ballast masses can be used for the BF additional mass. Because of the lot of ambiguity in BF weight, we will just use the old IM ballst masses for the BF additional masses (at least for the test hanging).
  * 1st wire breakers seem to be at Kashiwa now. Shoda will look for them on 12th.
  * Hirata-san updated the design of the IM flags, which will be ordered together with the modifiaction parts.

 * Rods
  * details of the rods are sent to Takahashi-san via e-mail.
  * Shoda asked Mirapro to analyse the suspension rods for OB. I am now asked to provide further information.

 * '''A/I'''
  * Preparing for the order (Checking 2D drawings, Finish the structural analysis summary.) (Saito, Shoda)
  * Making the design document (Shoda, Fujii)
