 * Hirata-san:
  * Made cables for LVDT.
  * Made drawings for new wire clamps.
  * Asked ATC for manufacturing parts.(and modified drawings.)
  * Asked quotes for SDC coating for hooks.
  * Sent packing tools for BF.
  * Talked with i-ject about quotes for payload.
 * Mark and Fabian at Kamioka (plus Enzo for 2 days):
  * Finished rebalance of IM
  * Reinstalled IRM, adjusted OSEMs
  * Replaced broken Type 3 cable on IM-H1 OSEM.
  * Fixed issues with k1visbs real-time model.
  * Started TFs from IRM OSEMs to IRM and IM OSEMs.		 === Type B (Mark) ===
==== Past week report ====
At Kamioka (Mark, Ohishi-san, Enzo, Yoshioka-kun, Kozu-kun):
 * We finished installing the RM OSEMs and installed the new Type5-2.2 and 5-2.4 OSEM cables.
 * We hung the RM and set its pitch.
 * We doubled-checked the BS and RM pitch, tightened the clamps and removed the winch system.
 * We installed the bottom section of the security structure to protect the RM/BS.
 * We lifted the IM/RM/BS section and weighed it. It was about 1.25 kg too heavy for the new BF, so we improvised a lighter set of ballast masses.
 * We installed the section of the security structure up to the BF ring, and the BF crossbars and jacks of the assembly frame.
 * We brought in the new BF.
 * We installed the BF-IRM rods and IRM top plate.
 * We reinstalled the IM flags and other items that had been taken off to use the winch system.
 * We hooked the BF-IM rod (with hex cable clamp). (We did not unlock the BF keystone.)
 * We cabled and tested the IM-PIT, IM-ROL and IM-YAW picos and the BF FR stepper (but not, yet, the BF LVDT).
