Just as an aside and not digging to deeply in IHI and Mitsubishi but there certainly seems to be a connection between the two companies.
1981 Japanese Aero Engines Corporation is established (jointly by Mitsubishi Heavy Industries, Ltd. and Kawasaki Heavy Industries, Ltd.).
That is taken from The History of IHI:

As for their being a connection today,
Knowing the details would make it easier to know the actual specifications of the snails.
