Patent number: 8658086Abstract: A method and a system for producing a change in a medium. The method places in a vicinity of the medium at least one energy modulation agent. The method applies an initiation energy to the medium. The initiation energy interacts with the energy modulation agent to directly or indirectly produce the change in the medium. The system includes an initiation energy source configured to apply an initiation energy to the medium to activate the energy modulation agent.Type: GrantFiled: December 13, 2012Date of Patent: February 25, 2014Assignee: Immunolight, LLC.Inventor: Frederic A. Bourke, Jr.

Publication number: 20140039084Abstract: The present invention aims to provide a surface modification method for a rubber vulcanizate or a thermoplastic elastomer, which can impart excellent sliding properties and excellent durability against repeated sliding motion and can allow the surface to maintain the sealing properties, without using expensive self-lubricating plastics. The present invention relates to a surface modification method for modifying a rubber vulcanizate or a thermoplastic elastomer as an object to be modified, the method including: step 1 of forming polymerization initiation points on the object to be modified; step 2 of radically polymerizing a monomer, starting from the polymerization initiation points, by irradiation with LED light at 300 nm to 400 nm to grow polymer chains on a surface of the object to be modified; and step 3 of esterifying, transesterifying or amidating side chains of the polymer chains.Type: ApplicationFiled: August 1, 2013Publication date: February 6, 2014Applicant: SUMITOMO RUBBER INDUSTRIES, LTD.Inventor: Yasuhisa MINAGAWA
