 * Hirata-san:
  * Updated the 3D assembly model for BS (among other issues, it turned out that parts were not correctly mated near where the suspension sits on the hydraulic jacks in the tank).
  * Liaised with IJECT.
  * Made an inventory for Type B (BS and SR).
  * Packed and shipped second winch to Kamioka.
  * Packed some jigs for adjusting BF blades.
  * Attended NINS information security seminar.
  * Attended the public hearing for the Opt-IR Research Division Chief Election.
 * Mark, Fabian, Enzo
  * Cabled IM picos and used IM yaw pico for adjusting RM. (Later, a wire broke at the connector, disabling the IM yaw, but we were able to continue by manually rotting the pic.)
  * Helped Takahashi-san in adjusting BF.
  * Initial round of adjustment made transverse perfect but overshot in longitudinal and made vertical unstable.
  * Second round of adjustment made vertical stable but left longitudinal offset.
  * Concluded that we can probably manage without bringing the BF back to Mitaka, but it will take some careful surveying of the existing offset and several more days of adjustment.		 === Type B (Mark) ===
==== Past week report ====
At Kamioka (Mark, Ohishi-san, Fabian, Enzo, Hirata-san, Yoshioka-kun, Kozu-kun):
 * We solved the problem with the OSEMs: cables had been plugged into the LED current monitor outputs, not the PD outputs.
 * We solved a problem with the real-time model freezing which turned out to be the IO chassis having lost power.
 * We took some mass off the IM to allow for the weight of the cables, and readjusted it in pitch and roll.
 * We aligned the IM

==== Plan for week of 8/28 ====
Kamioka: Mark (except Tue), Ohishi-san, Fabian (except Tue), Enzo (except Tue), Hirata-san, Yoshioka-kun (Fri), Kozu-kun (Thu, Fri).
 * Fix/adjust IRM OSEMs.
 * Add BF cap; cable and test BF-1 and BF-2 picos.
 * Lift and weigh BF/IRM/IM/RM/BS; adjust ballast mass.
 * Crane in SF.
 * Suspend BF/IRM/IM/RM/BS.

==== Plan for week of 9/4 ====
 * Install SF cap; route cables.
 * Lift and weigh SF/BF/IRM/IM/RM/BS.
 * Adjust SF ballast.
