'''Summary''': Ikeda-san worked on following items;

(1) He measured the length of the network cable (15956), and now is preparing to order all cables we need with DGS group.

(2) He got message from manufacturer that it is difficult to operate the picomotor for long time more 24 hours. (15958). So he is now considering to request AEL group to make the circuit box that turns power on and off with BIO signal like the stepper motor circuit.

(3) He made the new MEDM screen for stepper motor on MN stage which is developed by Nishimoto-kun. We can open the screen from [sitemap]/[STEPPING MOTOR]/[CRY_OVERVIEW] (15965).

=== VIS/PRM ===
'''Summary''':

(1) Miyo fixed the swapped cabling on the BF-damper for PRM with Nakagaki-san, and after that, the noise coupling of the transfer function at higher frequency is decreased to the same behavior of other PR suspensions (15994). By the way, the same noise coupling was reported in Type-A suspension [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=12678|12678]]. Is it caused by the same error?

(2) Ikeda-san touched the picomotor of PRM for his first operation (15957) before measure the calibration factor between picomotor and OSEM.
