  * Fabian took photos of the cleanroom in the ATC.
  * Hirata-san ordered wire for the BS.
  * Fabian weighed the masses that he'd been constructing in the cleanroom and found a 600 g discrepancy from the Inventor.
  * Hirata-san ordered a medium-capacity scale to help check the masses of the parts.
  * 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 ordered and received wire for the BS and RM (will be cleaned 7/19).
  * Hirata-san received remachined locking parts for the IM (will be cleaned 7/19).
  * Hirata-san ordered additional Misumi parts to be used with the IM locking parts.
  * Fabian and Hirata-san weighed the masses that they've been constructing in the cleanroom and found a 600 g discrepancy from the Inventor (too light) for the IM.
  * Hirata-san ordered a medium-capacity scale to weigh the masses of the individual parts more precisely.
  * Hirose-san and his team successfully removed the misglued prisms from the dummy BS.
  * Fabian travelled to Kashiwa and removed most of the glue from the face of the dummy BS (where the flags had been). There is still some adhesive remaining on both the face and barrel, which will require more work and a second trip.
  * Shoda-san took a suitable segment of geophone noise data for analysis. Fabian will track down the calibration factors.
