Abstract: Backup system and method that can determine a backup destination in consideration of disaster are provided. There are provided: a data acquisition unit 110 that acquires disaster information, network information, and node information; a replication group construction unit 130 that generates, based on the disaster information, and the like, replication group information including association information between a first node that stores original data and one or more second nodes that are candidates for backup destination of the original data, and saves the replication group information in a storage unit 120; a replication destination node calculation unit 140 that, when executing backup of the original data, calculates the second node as backup destination from the replication group; and a replication processing unit 230 that replicates and stores the original data into the storage of the second node.

The seat 4R further has a detacher 43 that detachably attaches the seat back 42 to the vehicle body 1.

Abstract: A temperature detection device and method that can simply and accurately detect the presence or absence of abnormal heating of a conveyor belt. Correlation data between an electrical resistance value of a passive IC tag embedded in a conveyor belt and a temperature of the IC tag when it is activated is grasped in advance when the tag receives a transmitted radio wave from a non-contact detector. Data of electrical resistance value when the IC tag is activated is received by the detector through a returned radio wave returned from the tag in response to the transmitted radio wave transmitted from the detector toward the tag embedded in the conveyor belt running. A temperature at a position of the conveyor belt where the tag is embedded is calculated in accordance with the data of the electrical resistance value received and the correlation data.

Abstract: An embedded body including, at one end portion of a coaxial cable, one side antenna unit and an IC tag that is passive and connected to the one side antenna unit, and another side antenna unit at the other end portion of the coaxial cable is embedded in a conveyor belt. The one side antenna unit and the IC tag, and the other side antenna unit disposed with an interval in a width direction and the coaxial cable is embedded extending in the width direction. A calculation unit determines whether a detector has received a radio wave emitted from the IC tag through the coaxial cable and the other side antenna unit in response to a radio wave emitted from the detector, and then whether a vertical tear has been generated in the conveyor belt based on the determination result.

Abstract: A conveyor belt is formed by covering a belt core body with a cover rubber. The cover rubber has a fine ridged/grooved structure formed on at least a portion of a surface thereof, and has a surface roughness of 1 ?m or more and 12 ?m or less, a degree of sharpness of 2 or more and 9 or less, and a specular gloss at an angle of incidence of 60° of 0.1 or more and 10 or less due to the fine ridged/grooved structure. The surface roughness is preferably 2 ?m or more and 5 ?m or less, and the degree of sharpness is preferably 3 or more and 5 or less, and the specular gloss at an angle of incidence of 60° is preferably 0.1 or more and 3 or less. Such conveyor belt is less likely to have a poor appearance due to bloom.
