Publication number: 20130320604Abstract: Provided is a viscous-fluid-enclosing damper which attenuates, by using viscous resistance of a vibration-damping composition, vibrations transmitted between a support and an object to be supported, the support and object being attached to a closed container enclosing the vibration-damping composition of a viscous fluid. The viscous-fluid-enclosing damper alters few vibration-damping properties even when used under high temperatures and/or conditions where the vibrations are repeatedly generated for a prolonged period. Also provided is the vibration-damping composition which is used for the viscous-fluid-enclosing damper. The viscous fluid contains a viscous liquid having dispersed therein at least one type of heat-resistant resin particles and a dripping inhibitor, the particles being selected from polyethylene and nylon having an average molecular weight of from 50×104 to 600×104 and an average particle size of from 10 ?m to 200 ?m and preferably from 10 ?m to 160 ?m.Type: ApplicationFiled: May 28, 2013Publication date: December 5, 2013Inventors: Junji Ohki, Akira Naito

Patent number: 7447521Abstract: A microprocessor used in a pair with a baseband processor for performing the baseband processing, is provided with a central processing unit for calculation processing, a counter capable of measuring time in the calculation processing by the central processing unit, and an interface which enables the baseband processor to read the counter. By making the baseband processor read the counter, the processing by the baseband processor is synchronized with the processing by the central processing unit in the microprocessor. Consequently, it is possible to establish synchronization between video and voice when the video processing and the voice processing are separately performed by different processors.Type: GrantFiled: June 28, 2007Date of Patent: November 4, 2008Assignee: Renesas Technology Corp.Inventors: Tetsuya Nakagawa, Katsuhiko Ishida, Akira Naito
