To make you fellers really happy, the Japanese do not use Phillips screws at all. They resemble Phillips screws, but are just different enough to evade the patents. That's why Phillips screwdrivers are not entirely satisfactory on Japanese machinery. I don't know what the Japanese call their version.

Edited to add: (I looked it up)
JIS  
Commonly found in Japanese equipment. Looks like a Phillips screw, but is designed not to cam out and will, therefore, be damaged by a Phillips screwdriver if it is too tight. Heads are usually identifiable by a single dot to one side of the cross slot. The standard number is JIS B 1012:1985 (End edit)

Most of the time, I use a Phillips screwdriver one size too large. That is, on a screw which would seem to need a #1 Phillips, a #2 works better. That seems to avoid stripping most of them, if the bit will fit into the hole. It may, or may not, work for you.
