A clamp ring and process for manufacturing a clamp ring to effectively reduce, if not eliminate, waste scrap from the manufacturing process. 1 to 20 parts by weight of hydrophobic inorganic oxide fine particles having hydrophobic groups and having an average particle size of 0. The device may also be used to provide perfusion support in low flow disease states such as hemorrhagic shock and cardiac arrest. Each of the touch zones has a zone sensing element for defining the zone coordinate. The employees themselves are empowered to be reengineering experts through the application of these techniques in a joint session, guided by the workshop leader.
