=== Type-A (Takahashi) ===
==== Past week report ====

[X-end]

4th(Mon)
  * Implemented the release sensors on the end plate for F1.
  * Put the F1 on the end plate.
  * Suspended the F2 and follows from the F1.
5th(Tue)
  * Calibrated the LVDT in F1.
  * Tuned the F1. The condition was changed by closing the cap. The lowest frequency was larger than 0.4Hz.
  * Assembled the twist pair flat cables.
  * Assembled the bridge frame.
6th(Wed)
  * Tuned the F1 changing the compression of blades.
7th(Thu)
  * Continued the F1 tuning. The lowest frequency was about 0.4 Hz.
  * Started the cabling between the F2 and the F1.
8th(Fri)
  * Continued the cabling.

==== Plan for coming weeks ====
 * Lift down the F2 and F1 into the corrugate tube.
 * Adjust the load on BF from the cross tube.
 * Finish the installation of F1.
