Abstract: From three-dimensional numerical data of surface irregularities of a tire inner surface in a tire of a construction where a sheet member is disposed on the tire circumference, a tire inner surface image is formed for which height direction data of the surface irregularities of the tire inner surface are expressed as pixel gradation values, and the tire circumferential direction and the tire width direction on the tire inner surface correspond to either of the longitudinal direction and the lateral direction of the image. A surface irregularity enhanced image is generated by subjecting this tire inner surface image to spatial frequency processing using a low-pass filter for the tire width direction and a band-pass filter for the tire circumferential direction. A determination is made of whether a recessed region exists which indicates a bonding defect of the end portions of the sheet member.

Abstract: An imaging device inserted into an opening of a tire includes a light source, a mirror, and a camera and is configured so that the mirror revolves around a rotation shaft while an orientation of a surface of the mirror changes. The mirror is set in an imaging position by being revolved around the rotation shaft to be inserted into a tire cavity region. The tread inner surface of the tire is scanned with slit light by being irradiated with the slit light. During the scanning with the slit light, a line irradiation region on the tread inner surface formed through the irradiation of the slit light is imaged via the mirror by the camera from a direction tilted with respect to the tire circumferential direction, and image data is output.

Abstract: An outer packaging material for a battery or capacitor includes, a base layer, a barrier layer, an adhesive layer and a sealant layer which are sequentially laminated, has high adhesion between the barrier layer and the adhesive layer and is a good moisture barrier. The adhesive layer includes a maleic anhydride-modified polypropylene, wherein ? and ?, defined below, satisfy all the following conditions: ??0.09; ??10; and ???2.0; wherein a represents a ratio (A1790/A840) of a peak height (A1790) at 1790 cm-1 to a peak height (A840) at 840 cm-1 in infrared absorption spectrum of the maleic anhydride-modified polypropylene and ? represents a thickness of the adhesive layer in ?m.

Abstract: Disclosed is a tire marking system for marking tire identification information onto tires based on tire information in each of bar code labels adhered to the tires. The tire marking system includes a database server which includes a first database containing data of tire production plan information including tire quantity information and data of tire identification information, and a second database containing data for managing whether marking of the tire identification information is performed onto the tires. The tire marking system further includes client computers connected to the database server via communication media, and a image reading device and a tire marking device which are connected to each of the client computers. When the tire marking device completes the marking, in the second database of the database server, data of the marked tire identification information is updated to indicate that the marking is completed.
