Akutsu and Takahashi washed 36 pieces of OSEM coil bodies with acetone in a ultrasonic bath. They are now located at the ATC ISO-1 clean booth to dry. Later, Akutsu will put vac seals to the coil to fix the wire edges, and pack into clean bags, and send to KEK for baking.

The number is just determined by the fact (1) PR2, 3, BS OSEMs are urgent, so 30 pieces are needed, (2) the ultrasonic bath can contain 12 pieces at once.
