Abstract: A power actuation structure for turning electric power ON and OFF of a computer host through an extension mechanism without wiring includes a switch located on a circuit board of the computer host. The computer host has partitions to define installation areas for holding electronic devices. Each of the partitions has a displacement section corresponding to the switch. The displacement section has an actuator which may be driven to compress the switch to set the electric power ON or OFF.

Abstract: The golf ball has a solid core and a cover surrounding the core. The solid core is formed of a rubber composition that has a co-crosslinking agent and preferably an organic sulfur compound blended therein, with a portion of the co-crosslinking agent and the organic sulfur compound being micro-encapsulated within a thermoplastic resin, and a remaining portion of the co-crosslinking agent being in a non-encapsulated state. This improves dispersibility of the co-crosslinking agent and the organic sulfur compound within the rubber composition, and enables adjustment of the crosslinking pattern of the rubber molecule main chains. Thus, resilience and durability of the golf ball are improved.
