newbie ?s

A couple of questions just to prove my abysmal ignorance to anyone who wasn't sure.
1) I know that the Subaru logo is a stylized rendition of the constellation Pleiades, and that Alcyone is the brightest star in Pleiades, but is Alcyone also what the Japanese SVX was called?
2) What is the cool looking 'horns' logo really supposed to be? It looks like a very stylized longhorn steer to me, but i really like it.
Thanks for any info. Marc
