A socket connector configured such that elongated guide holes are formed in the housing so as to receive guide members of a device to be connected, and a slide member is attached to the housing to be slidable in the longitudinal direction of the elongated guide holes so as to restrict the guide members to their initial positions. By examining a processor’s instruction set and execution unit implementation’s critical timing paths, instructions are classified into speed classes. The modifier component may in some embodiments be an ethylene \u03b1-olefin copolymer with a density \u22670.
