20110282966 | CONTENT DISTRIBUTION SYSTEM AND GATEWAY DEVICE, AND PROGRAM - A renderer (DMR) in a second local area network via an Internet is enabled to reproduce content in a first local area network. A content transmission system generates a virtual DMR corresponding to a DMR (content reproduction device) in a content reception system. A DMC (controller) and a DMS (content server) recognize the virtual DMR as if to be an actual DMR and communicate therewith. This enables content to be reproduced in an actual DMR in a different home network residing beyond the Internet without any modification on the DLNA standard. A transmission gateway device (transmission mechanism) relays communication destined for the virtual DMR (instructions and content) to a reception gateway device (reception mechanism). Also in the content reception system, the actual DMR is capable of processing communication from a different home network by communication only with the reception mechanism. This negates the need for modification on the DLNA standard. | 11-17-2011 |

20120031337 | DIVIDED ANNULAR RIB TYPE PLASMA PROCESSING APPARATUS - A plasma stream-derived deposited matter formed on an annular rib for droplet capture in a plasma processing apparatus is prevented from falling into a plasma generation portion and causing a short circuit. The annular rib for the droplet capture is divided into multiple rib segments.
