Orion
ORION is japanese company, founded 1958 by Shigemasa Otake. In an interview, Alan Sugar has confirmed that Amstrad planned to export CPCs to "far east", using Orion as a partner. As far as known, the partnership didn't worked in that direction - there have been no CPCs sold using the Orion brand. However, it worked the opposite way around: Amstrads CTM640/CTM644 and GT64/GT65 monitors contain cathode ray tubes from ORION.
