Hello Fuku,

I tried call yur house and also your mobile at 10 pm your time, no
answer?

1.  A.  Sorry about the big trouble with the hoses.
     B.  I will have Don Petersen order and ship new hoses but we can
not get the hoses to Takenaka in time for their first tests, it would
take almost 1 month to get new hoses made and shipped to Takenaka.
      C.I think you can make the existing hoses work if you have 2 each
2 inch return hoses to extend the return hose lengths.  Is that correct?
 Dohnen has many 2 inch hoses with connectors.  Ito-san will know if Dr.
Horikiri would let us use 2 of his hoses for one month.

2.  The delta p cells (with parts) left here 6 January for 2 day
shipment to you at MTS-J.  They arrived DHL Japan facility Tuesday, Jan
11, but were sent to the wrong facility, as of 06:27 11 January, they
were sent to the correct facility.  Airway bill number is 9105938343.
My guess is you will have the parts tomorrow.

3.  A.  Rod is working on getting the structural software.  You do know
that the standard software had a problem.  I have heard that the
software problem has been corrected, but I do not know if the new
software is available for shipment yet.
    B.  There is no remote control Pod (?, I think you mean remote
control station?)  in the BOM.     These are expensive, many, in fact
most, structural shipments do not have those, why is it now included in
the Takenaka job?

4.  N/A

5.  I will ask Rod to answer.  I understood that the controller had no
problem when here at MTS.  I would be surprised if we had to replace the
backplane.

6.  Rod says no ground is usually not a problem.  I did have a problem
in Dalian, it turned out the console wiring ground was not good so there
was a voltage difference of 50 volts beween the console ground and the
actuator.  Personally, I prefer to always have an actuator  ground.  It
is cheapest if you just buy wire and connecting lugs in Japan and
install the grounds.

Regards
Omar
