=== Type-A (Takahashi) ===
 * [[http://gwwiki.icrr.u-tokyo.ac.jp/JGWwiki/KAGRA/Subgroups/VIS/TypeA/Meeting|Minutes of Type-A Meeting]]
 * Pre-isolator: Started the assembly of pre-isolator in ATC. Measured the sensitivities of 3 ACCs at the site. 
 * EQ stop, release sensor, dummy payload: Production is on going.
 * BF damper: The bidding was announced on 14th. Open bidding is on 9th November.
 * Maraging wire: Obuchi-san redesigned of the wire for Type-A with safety margin of 2.
 * Installation: Making assy. drawings. Designed the hoist tool.

=== Type B (Mark) ===
 * Type B Past Week Summary
  * Fabian, Mark and Liu-kun did BS installation at Kamioka:
   * Replaced the thrust bearing in the BF with a stainless version. While replacing the picomotor spring, they found several issues with screws.
   * Removed the sheet metal cable clamp on the bottom of the BF and installed a redesigned one.
   * They installed the "flying saucer" cable clamp on the maraging rod between the IM and BF, and attached the cables. There was an issue with the cables from the bottom OSEMs, which are too short by about 300 mm.
   * Ruspended the IM. Relative to the mass budget, about 700 g of trim mass had to be taken off to get good balance. There was also a problem with rubbing. It turned out that the keystone and the attached central PEEK coil former for the LVDT were at an angle, and the inside of the coil former was fouling on the outside of the pole piece for the magnets. It's not yet clear why the keystone was misaligned.
  * Hirata-san: 
   * Made drawings of (revised) stub flag gluing jigs.
   * Worked on BS full-assembly drawings for Saito-sensei.
   * (For other groups) 
    * Made a 3D model of maraging wires.
    * Finished making drawings of PRM inner frame.
    * Worked on re-setting up PC after crash.
 * 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 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-Bp (Shoda) ===
 * BFRM
  * Still waiting for ordering process.
  * Maraging rod drawing is approved.
  * Some minor updates are done.
  * I and Saito-san agreed that the assembly test will be done in Mitaka.

 * Stab Flags
  * Hirata-san made the drawings. We will ask for the cost estimation soon.

 * Assembly frame
  * Asking cost estimate

 * Install procedure
  * I will draw some pictures how to install whole suspension chain into the chamber.

 * Flag removing jig.
  * Being late. Simon told me that it is safe to have the OSEM flags because of the circuits preparation.

=== IMMT (Ohishi) ===
 * Put a report here

=== Watchdog system (Tanaka) ===
 * Conference material PCB Design Draft version.[[http://gwdoc.icrr.u-tokyo.ac.jp/DocDB/0057/E1605760/001/Project_WDS_PCB_Design_Ver_0th-161021.pdf|PDF]]
