[_Microft]

Slightly OT, just in case someone has a similar problem: I (ab)used Wikipedia as special dictionary (1) during my thesis by means of a script that looked up the english article to the search-word and extracted the title of the link to the article in my mother tongue out of it. Admittedly it was a crude solution but it worked well enough then.

(1) It was meant to be used for technical terms that wouldn't be in most normal dictionaries.

I used to use this trick as well. Wikipedia is easily the best jp <-> en technical dictionary I've ever used.
