=== Minutes ===
 0-1 Assembly model (Ishizaki)
  * Step: From EQ stop, next with chamber.
 0-2 Simulation (Okutomi)
  * Problem: Conversion to Simulink was ok. The structure of control has a problem in Matlab. Reconstructing now.
 3-5 ACC preparation (Sato)
  * Space: Make working space in the 20m lab.
 5-1 Manufacturing of blade (Takahashi)
  * Design: 5 blades are used for 200kg load.
 5-6 Design of damper (Sato)
  * Device: Asking design of LVDT-Act. to VIRGO. The device is located at the center of mass.
 6-1 Design of EQ stop (Ishizaki)
  * Structure analysis: Two cases were calculated. Share stress was 1/6 of limit, and principal stress was 1/7 of limit respectively in the maximum case.
  * Modeling: Making with consideration of procedure and tools.
  * Frame lock: Maximum stress was 160MPa with thickness of 30mm (limit 180MPa).
 6-4 Design of release sensor (Sato)
  * Position: Inner side of the stage. Need to addtional machining to the EQ stop plate.
  * Electronics: Circuit is simple in the test (handmade).
 8-1 Design of dummy payload (Okutomi, Ishizaki)
  * Condition: 25cm mirror, alignment by moving mass. Make a cartoon.
  * Actuation: Length control is necessary? Check PZT actuator.
 9-1 Establishment of procedure (Takahashi, Okutomi)
  * Test plan: Prepare for 2 sets of release sensors. Check FR for 2 BFs.
