I would like to inform you of problems on the images of publications.
The Japanese characters are unreadable on the front page of the WO2013/001945(A1).
Also, we can see something like a piece of paper on page 23 of the WO2008/023816.
I have transmitted your findings to the PCT operations team for correction (There will be probably a republication). Thanks a lot for pointing these defects to us.
