Abstract: An electrostatic discharge device including a gate structure, a plurality of first doped regions, and a plurality of second doped regions. The gate structure is disposed on a substrate. The gate structure includes a body part and a plurality of extension parts. The extension parts are connected with the body part, and an extension direction of the body part is different from an extension direction of the extension parts. The first doped regions are located in the substrate between the extension parts. The second doped regions are located in the substrate at two outer sides of the extension parts. The first doped regions and the second doped regions have different conductivity types.

Abstract: The present disclosure relates to an improved hand grip 20,30, 30, 40, 50 for a shock imparting implement, like a golf club grip, that provides a selected portion A of the cap 22, 32, 42, 52 on the grip with a greater hardness than the portion B of the body 24, 34, 44, 54 of the grip. The selected portion A of the cap 22, 32, 42, 52 improves the torsional stiffness to resist twisting during the swing of the implement.
