does "Mitsubishi pencil co" have anything to do with the car manufacturers?

[viva le Eire!]

i have a Mitsubishi pen and was wondering if the company is owned by the same people as the car company!
i have a thing called a digivox that decodes the TV stations to get digital TV for a once off fee, no contract, no monthly payment and that is also made my mitsubishi, is that the same company too?
