A fuzzy extractor includes an initial key generating part including a true random number generator, and a key regenerating part. The true random number generator generates a true random number using a read-out signal read from the reading part or a pixel signal read from the pixels of the pixel part in a true random number generation mode. The initial key generating part generates helper data and an initial key based on the true random number generated by the true random number generator and variation information acquired as a response when the initial key is generated. The key regenerating part generates, when a key is regenerated, a unique key based on helper data acquired when the initial key is generated and variation information acquired as a response including an error when the key is regenerated.

An information processing device includes acquisition means for acquiring a plurality of tree structure data in which information groups are represented by tree structures and merge means for generating merged tree structure data merging the plurality of tree structure data. The merge means merges, for information satisfying a condition indicating that a certain distance from other information in the tree structure data is maintained, a subtree at a level below the information in the tree structure data, into the merged tree structure data, wherein the information satisfying the condition is included in a node selected from the plurality of tree structure data; and reorganizing for information satisfying a condition indicating that the distance between pieces of information is short, a merged subtree by merging subtrees below the information in the tree structure data into the information.

A placement device may reduce the cost for placing an object when a placement destination, in which an object is placed, changes due to the addition of a placement destination. A placement device may: determine, upon receiving object information assigned to an object, as the placement destination in which the object is placed from among one or more placement destinations each having an assigned set value, the placement destination added most recently and assigned a set value larger than a characteristic value derived uniquely based on the object information; and change, when a placement destination is added, based on an available capacity representing the amount of objects that can be newly placed in the placement destinations, the set value assigned to at least one of the placement destinations such that the determined placement destination does not change to a placement destination other than the placement destination added last.

Placement device, placement method and recording medium, that stores placement program information processing device

An apparatus for placement of an object includes a placement site search unit. The placement site search unit searches a placement site of the object based on a first vector element that has organized first identifiers for first placement sites existing in a system and on a second vector element that has organized second identifiers for second placement sites not existing in the system (FIG.1).

A material for a gasket, wherein a chromate or non-chromate film, a phenol resin primer layer and a polyol-crosslinkable fluororubber layer are formed on one or both surfaces of a steel plate in this sequence from the side of the steel plate; the polyol-crosslinkable fluororubber layer is a rubber layer obtained by applying a fluororubber composition that comprises fluororubber, a polyol-based cross-linking agent, an amine-based cross-linking accelerator and silica to the phenol resin primer layer, followed by heating; and the amine-based cross-linking accelerator is a tertiary amine or a salt of a tertiary amine obtained by a reaction between a tertiary amine and an acid. Provided is a material for a gasket mounted in an engine of a vehicle that, in the actual use environment, does not suffer rubber peeling in a part where it contacts water or an anti-freezing solution even if the gasket is used in a state where it contacts different types of metals and, in a sealing part around a combustion room, abrasion or ply separation of a rubber layer hardly occurs.

Material for gasket

Provided is a sealing material that exhibits excellent sealing property at a low contact pressure and a method for producing the same. A sealing material according to the present invention is a sealing material including a metal plate and a foamed rubber layer formed on one surface, or each of both surfaces, of the metal plate, in which the foamed rubber layer has a closed cell rate of 50% or more, and a surface of the foamed rubber layer has a maximum height determined by a method in conformity to JIS B 0601-2001 of 40 &#x3bc;m or less.

A distributed storage system comprises a plurality of data storage nodes that store a plurality of object data items in a distributed manner. The plurality of object data items are respectively characterized by a data coordinate and identified by a data identifier. The plurality of data storage nodes are respectively assigned a node coordinate in a space identical to that of the data coordinate. After selecting as first data storage nodes from among the plurality of data storage nodes a plurality of data storage nodes each assigned a node coordinate having a relatively short distance from a data coordinate characterizing each of the plurality of object data items, any of the object data item is respectively stored in a data storage node determined based on a data identifier that identifies the object data item from among the plurality of first data storage nodes.

Distributed storage system and distributed storage method

Disclosed is an object arrangement apparatus which arranges a plurality of objects approximately uniformly to a plurality of arrangement destinations by a comparatively easy processing configuration. This object arrangement apparatus includes an arrangement destination determination means. The arrangement destination determination means refers to sequence information generated based on unique information for objects and refers to corresponding information between arrangement destination identifiers identifying arrangement destinations of the objects and second numbers associated with the arrangement destination identifiers. The arrangement destination determination means generates first numbers by using the sequence information, the first numbers not having a correlation therebetween when the first numbers are generated with different sequence information, and repeats generating a new first number until the first number matches the second number contained in the corresponding information. The arrangement destination determination means determines, when the first number matches any of the second numbers, to arrange the object to an arrangement destination corresponding to the arrangement destination identifier related to the matched second number.
