 * No type-A meeting in this week.
 * EQ stop, release sensor, dummy payload: The specification document and drawings were fixed. The bidding was announced on the 17th.
 * Installation procedure: The review was held on the 10th.
 * Standard filters: Cheking of 6 sets were finished and shipped to Kamioka.

  * Saito-san made the 1st version of the 2D drawing. Though we still have small modification, we can start cost estimate.
 * F7 LVDT
  * Virgo LVDT test is ongoing. The measured calibration factor and noise level is worse than expected. More tuning is required.

  * BF weight is lighter than the 3D model. (CAD: 50 kg, measured: 45 kg.) Shoda has not been able to find any reason yet. Further investigation will be done in next week.
