Abstract: Methods of vulcanization using a high content sulfur polymer, instead of elemental sulfur, have been developed. These high sulfur content polymers are referred to as Chalcogenide Hybrid Inorganic/Organic Polymers (CHIP) materials and have good polymer compatibility in that they are soluble in a number of polymers. Furthermore, CHIP materials may have weaker bonds than the S—S bonds of elemental sulfur and thus provide for a higher crosslinking efficiency vulcanization.

The slider mechanism includes a first plate and a second plate slidably combined with the first plate. The second plate has a cam profile formed along siding direction. A resilience unit is mounted on the first plate to exert resilient force perpendicularly to moving direction of the second plate. A roller is rotatably attached to an end of the resilience unit. The roller runs along the cam profile while the portable terminal opens or closes. Formed at a desired position of the cam profile is a depression on which the roller rests to hold the terminal in place at closed or opened state, or at any other desired position.
