摘要： A method for producing a sintered body is provided. The method for producing the sintered body comprising: forming a green body by molding a composition for forming a green body into a specified shape to obtain the green body, the composition comprising powder constituted of a metallic material and a binder containing a first resin which is decomposable by ozone; first debinding the green body by exposing the green body to a high ozone content atmosphere to decompose the first resin and remove the decomposed first resin form the green body to obtain a brown body; exposing the thus obtained brown body at least once to a low ozone content atmosphere whose ozone concentration is lower than an ozone concentration of the high ozone content atmosphere to obtain an intermediate brown body; and sintering the intermediate brown body which has been exposed to the low ozone content atmosphere to obtain the sintered body. By using the composition mentioned above, it is possible to safely, easily and cost-effectively produce a metal sintered body having a reduced metal oxide amount and improved properties (dimensional accuracy). Such a sintered body is also provided.

摘要： Image data encoded in units of a tile is processed to define a hierarchical structure by repeatedly forming one tile group from adjacent tiles and another tile group from adjacent tile groups. Plural partially encoded data a tile located at a terminal of the hierarchical structure are arranged in ascending order of priority of decryption to define a tree having as nodes tile groups, tiles, and partially encoded data. Encryption key information is generated for a node located at an uppermost layer of the tree and, up to a node located at a terminal, encryption key information is generated for a node of interest based on encryption key information for a node at an upper layer. When a node of partially encoded data is designated as an object to be encrypted, partially encoded data at a higher layer containing the designated object is set as an object to be encrypted.

摘要： A code stream and data indicating a normalization method are inputted to a normalization processing unit 21, and the normalization processing unit applies normalization processing to the code stream to generate a normalized code stream. Next, when signature data is inputted, a verification processing unit 22 performs encryption and decryption processing with respect to the signature data using a public key Kp and calculates a Hash value (first Hash value) and, on the other hand, calculates a Hash value of the normalized code stream (second Hash value). Next, the verification processing unit compares the first Hash value and the second Hash value and, if the first Hash value and the second Hash value are equal, judges that the code stream is not falsified. On the other hand, if the first Hash value and the second Hash value are not equal, the verification processing unit judges that the code stream is falsified.
