 * Type B Past Week Summary
  * Fabian took photos of the cleanroom in the ATC to help decide whether it is a good place to assemble PIs for Type A/B.
  * Hirata-san wiped one set each of wires for the BS and RM (addition sets pending).
  * Hirata-san washed remachined locking parts for the IM and screws for jacks.
  * Hirata-san liaised with Ikenoue-san of ATC to get winch parts designed for the new wire thicknesses.
  * Hirata-san worked on the Inventor 3D assembly of the SR2.
  * The scale for checking the masses of the IM parts was received.
  * Fabian and Hirata-san identified an issue with the lock screws between the IM and IRM. The screws were too tight in the holes and adjusting the size with a die caused large flakes of the black coating to come off. (These screws were ordered before the current screw policy was instituted.) Hirata-san will order better screws from Misumi and have additional machining done on them.
  * Fabian tracked down the calibration factors for the geophones and generated a calibrated plot.
 * Type B Past Week Summary - week of 8/8
  * Mark, Fabian and Hirata-san cleaned glue off the dummy BS, attached Akutsu-san's new SS mirror plates, reglued the flags and prisms, and removed the gluing hardware, so the dummy BS is ready for shipping. Tatsumi-san's refinements to the tooling (especially the new flag holders) worked very smoothly. We were more generous with the glue and much more careful with the alignment of the prisms to the barrel, both during rehearsal and the final gluing.
  * Mark wrote up the gluing procedure as a new document [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=5505| E1605505]]. (The original plan was to do an addendum to Tatsumi-san's PR gluing procedure JGW-E1504248, but there was too much material.)
  * Hirata-san organized with Takahashi-san to get the BS payload masses shipped to Kamioka. They will go in an air-ride truck on Wed 8/17 together with a load of Type A stuff, and will arrive early on Thu 8/17.
  * Hirata-san shipped the collection of Type B fasteners to Kamioka, to arrive Mon 8/15.
  * Hirata-san measured another standard filter and cleaned various parts for people.
  * Hirata-san worked on the SR2 Inventor assembly. He spotted a problem with the orientation: given the position of the pistons in the SR2 tank (according to the assembly from Mirapro), mating the standard Type B SR chain and the chamber in the natural way puts the optic at 90° to what it needs to be. A similar problem was found in the Type B Test at Mitaka, and it was eventually worked around, but with some difficulty. Hirata-san will investigate the best way of making a correction.
  * Komori-kun, Kuwahara-kun and Akutsu-san calibrated an initial batch of 7 wide-mouthed OSEMs.
  * Fabian worked on the payload assembly procedure.
 * Type B Past Week Summary - week of 8/15
  * Hirata-san shipped the fasteners to Kamioka, and they arrived Tuesday.
  * Hirata-san shipped a large load of Type A and Type B items, which Mark and Fabian received on Thursday 8/18.
  * Akutsu-san shipped the first 7 OSEMs.
  * Mark, Fabian and Zhao-kun did a major cleanup and reorganization of the BS clean booth at Kamioka, putting PR2 stuff in boxes, vacuuming and wiping, and making space.
  * Mark, Fabian and Zhao-kun set the crossbeams of the assembly frame to their correct positions and installed the EQ stop ring on top, ready to receive the IM. This is the first actual installation activity for Type B.
