A method for producing contrast rich, permanent and slag-free characterizations, particularly on polished semiconductor disks is described, in which the surface for generating the surface pattern is partially melted by laser radiation. According to the invention, a surface segment corresponding to 1.5 to 6.5 times the surface area of the desired surface pattern is irradiated, and the semiconductor...

A simple low cost building arbor having a wide range of axial length or bead set length variation. The arbor has no moving parts which are not of rubber or rubber-like material and is operable by air pressure alone. An expandable ring expands, by air pressure, to hold a bead ring in axial position and independently a turn-up bladder is expanded to turn a ply sleeve end about the bead ring. Operati...
