An uncoated, highly reflective, impact-resistant injection-molded article which comprises a rubber ingredient and a thermoplastic resin, characterized in that the rubber ingredient has been dispersed in the thermoplastic resin, the rubber ingredient has a coefficient of linear expansion of 12. The expander may be hydraulically actuated. Similarly, when a device on the local network sends an object to the UPnP MS, the UPnP MS and SIP UA cooperate to enable the SIP UA to send the content of the object as SIP content to a remote SIP terminal.
