Oh, I see, Manabe san, great guy, we have spoken on the phone.
He is an mechanical engineer at a refinery here in Japan, on talented guy for sure.
Most of the English he uses, he checks by running it through a machine translator, this often give odd sayings and such, but you can get the idea of what he is talking about.
I'd love to meet him one day, I'm sure we would have a lot to chat about, but he really, REALLY lives at the other end of the country, and he works a lot, like me.
Still, it is a great site!
Cheers!
