  * 30mHz IP for Type-A (Remote stopper).
  * Remote adjuster of F1 damper for Type-A/B.
  * H4 geophone for Type-B.
  * Accelerometer for Type-B.
  * BF damper for Type-B
  * Wide range OSEM for Type-B/Bp.
  * Improvement of the Type-C suspension.		   * 30mHz IP for Type-A (Remote stopper): What is merit? Simulation is necessary.
  * Remote adjuster of F1 damper for Type-A/B: Height adjustment at BF is more important.
  * H4 geophone for Type-B
  * Accelerometer for Type-B: Manufacturing is ongoing in ATC.
  * BF damper for Type-B: Design to avoid reinstallation of the tower.
  * Wide range OSEM for Type-B/Bp: Priority is not high.
  * Improvement of the Type-C suspension: 1-3Hz vibration made a jump in pitch. KFC suspension with size variation can be available.
