  • Patent number: 10421318
    Abstract: A pneumatic tire includes film layers of thermoplastic resin or thermoplastic elastomer composition made by blending an elastomer with the thermoplastic resin, which are superposed by winding the film layer in the circumferential direction of the tire multiple times, a thickness of the film layer is in a range of 0.02 mm to 0.2 mm and a thickness of the rubber layer is in a range of 0.1 mm to 1.2 mm, and the tire wherein a rubber film is interposed between the film layers. The pneumatic tire is produced by preparing a laminated body in which the rubber layer is stuck to at least one surface of the film layer; interposing the rubber layer between the film layers by winding the laminated body in the circumferential direction of the tire multiple times; forming an uncured tire which includes the film layers and the rubber layers; and curing the tire.

  • Patent number: 9962892
    Abstract: Provided is a pneumatic tire improved in the durability at a splice part (2) of a tire-constituting member (1) and in the uniformity of the tire, and a process for producing the same. The pneumatic tire includes a tire-constituting member (1) having a splice part (2) on which a thin film (3) made of a thermoplastic resin or a thermoplastic elastomer composition is coated and fusion-bonded. In addition, the process for producing the pneumatic tire includes a step of heating the thin films (3) each arranged at the splice part (2) of an inner liner layer (14) or the splice part (2) of a carcass layer (13) so as to thermally fusing the thermoplastic resin or the thermoplastic elastomer composition constituting the thin films (3).

  • Patent number: 8050535
    Abstract: A contents display control means displays video contents in a contents display screen area, a virtual space display control means displays a two-dimensional or a three-dimensional virtual space and an object appearing in the two-dimensional or the three-dimensional virtual space in a virtual space display screen area, and a motion control means controls, when the video contents is displayed in the contents display screen area, a motion of the object, with reference to additional information of the video contents and motion control information specifying the motion of the object when the additional information satisfies a certain condition. Accordingly, a novel video contents display method can be provided with the use of the additional information multiplexed into the video contents.
