Patent number: 8229000Abstract: An apparatus and method are provided for enabling inhibition or reduction in the amount of processing to decode and to re-encode image data to be compatible with a transmission capacity upon delivery of converted images. Image data converter 205 converts and transfers an image of a conversion start frame in an intra-mode. Switch 206 transfers the image in the intra-mode, which was transferred by image data converter 205, as the conversion start frame, and transfers image data 103 demultiplexed from received data 100 for the remaining frames. Data synchronization/output unit 208 establishes the synchronization of image with audio by temporally adjusting audio data backward when the converted image data increases in size.Type: GrantFiled: September 5, 2006Date of Patent: July 24, 2012Assignee: NEC CorporationInventors: Hironori Ito, Kazunori Osawa

Publication number: 20100314357Abstract: A resin-molded vacuum valve has an internally hermetically sealed vacuum vessel, a fixed axis having a fixed electrode at one end thereof, and a movable axis having a movable electrode at one end thereof and facing the fixed axis in the vacuum vessel. The fixed and movable electrodes are fixedly and movably attached, respectively, to respective ends of the vacuum vessel with a contact therebetween. Further, a conductor connected to the fixed axis extends from a pull-out opening. First, second, and third electric field concentration alleviating shields are disposed near the fixed axis, near the movable axis, and near the pull-out opening, respectively. Buffer layers cover the outer peripheries of the vacuum valve and the conductor, and a resin insulator allows the movable axis to be movable, and buries and fixes the fixed axis, the vacuum vessel, the conductor, the buffer layers, and the electric field concentration alleviating shields.Type: ApplicationFiled: June 12, 2009Publication date: December 16, 2010Inventors: Masato KOBAYASHI, Kenji TSUCHIYA, Kazunori OSAWA, Akinori YOSHITANI, Yukihiro UOZUMI
