No. Mitsubishi Electric and Mitsubishi Heavy Industries are two
separate, and sometimes competing companies. They both share a
common heritage going back to Mitsubishi Shipbuilding and
Engineering Company. Mitsubishi Electric was spun off as a new and
separate company in 1921 and focuses on advanced electronic
products.
Mitsubishi Heavy Industries is more in the industrial space,
such as forklifts etc.
