Where can I get an English machine-translation of a Japanese patent or utility model document?

For Japanese patent and utility model douments from 1993 onwards, the Japanese Patent Office offers free online translation into English. The translation is available on the Patent Office's free-of-charge "IPDL" (Industrial Property Digital Library) internet service at http://www.ipdl.inpit.go.jp/homepg_e.ipdl.

 

On the IPDL page, select "Patent & Utility Model Gazette DB". Type the number of the searched publication, leading to the English abstract thereof (if available) in the Patent Abstract of Japan (PAJ) database. Clicking the "Detail" button on the top of the bastract page starts the machine translation of the published document.
