  • Patent number: 9896553
    Abstract: Provided are a method for manufacturing a rubber composition, which method can give a rubber composition provided with excellent reinforcement properties by improving the dispersibility of fibers in a rubber component when the fibers are added to the rubber, a rubber composition obtained using this method, a vulcanized rubber, and a tire. The method is a method for manufacturing a rubber composition comprising short fibers, comprising a dispersion preparation step for preparing a short fiber dispersion by adding the short fibers into a liquid, a mixed dispersion preparation step for preparing a mixed dispersion by adding at least one dispersant selected from the group consisting of carbon black and inorganic compounds into the short fiber dispersion, a mixing step for mixing the mixed dispersion and rubber latex to prepare a rubber-short fiber mixed solution, and a drying step for drying the rubber-short fiber mixed solution to give a rubber composition.

  • Publication number: 20140139647
    Abstract: According to an embodiment, a stereoscopic image display device includes a display unit, a first obtaining unit, a measuring unit, a determining unit, and a parallax control unit. The display unit displays thereon a stereoscopic image. The first obtaining unit obtains a captured image that is obtained by capturing a space including a viewing position in which a viewer supposed to view the stereoscopic image. The measuring unit measures an angle of convergence of the viewer who appears in the captured image that is obtained by the first obtaining unit. The determining unit determines based on the angle of convergence measured by the measuring unit whether the viewer is fatigued. The parallax control unit performs control to reduce an amount of parallax of the stereoscopic image when the determining unit determines that the viewer is fatigued.

  • Patent number: 8073957
    Abstract: A communication control system for intervening in the communication between a PC terminal in an external network and a portable telephone terminal with an electronic mail transmission/reception function in a mobile communication network has a database in which a portable telephone number and a mail account are stored in association with each other. Upon receipt of an access request with an FQDN to a predetermined portable telephone terminal from the PC terminal, the communication control system solves the name of the portable telephone terminal by searching the database on the basis of a host name (mail account name) extracted from the FQDN to acquire the telephone number corresponding to the host name (mail account name) as address information, thereby making a connection of the communication to the mobile communication terminal on the basis of the address information acquired by solving the name.

  • Patent number: 6716718
    Abstract: A trench is formed by performing an anisotropic etching treatment on a silicon substrate with the use of a mask pattern including a pad oxide film, a polysilicon film, and a silicon nitride film formed on the silicon substrate, as a mask. Next, the side surface of the polysilicon film is retreated by etching so that the part of an oxide film formed on the side surface of the polysilicon film may not be hung over the part of an oxide film formed on the side surface of the pad oxide film. Next, an oxide film is formed by performing a thermal oxidation treatment on the inner wall surface of the trench including the exposed side surface of the polysilicon film. This produces a semiconductor device that prevents voids from being formed in a trench isolation structure.
