Abstract: An information management system comprises information processing unit 51 which reads out self ID number data and reference ID number data from each RFID tag, and additionally writes all the self ID number data and reference ID number data into an ID table. The data in each row of the ID table is the self ID number data and reference ID number data that are stored in each RFID tag. “0” is set to all rows of a link flag setting region, and it is checked whether a value in the M-th row of the reference ID number data is equal to a value in the N-th row of the self ID number data. If both are equal, then “1” is set to the N-th row in the link flag setting region. These processing operations are repeated for all rows of the ID table.

Abstract: In an electronic tag data read/write apparatus, an electronic tag receives a response request from a reader/writer, generates a random number in a random number generator, stores the random number in a memory, and transmits the generated random number to the reader/writer. The reader/writer conducts masking processing on write data on the basis of the random number every size of the received random number, repeats the masking processing until all of the write data are subjected to masking processing, and then transmits the masked write data to the electronic tag collectively. The electronic tag conducts deciphering processing on the received masked write data every size of the random number stored in the memory, repeats the deciphering processing until all of the masked write data are deciphered, and writes the write data into the memory.

Abstract: For making difficult to copy data of a RFID tag, while enabling to detect it when copying the data, easily, but without exerting ill influences upon the existing specification thereof, within the RFID tag 100 is provided a readout exclusive bank, other than banks provided in accordance with the existing specification. RFID identification information is stored into the readout exclusive bank of the RFID tag 100, when the RFID tag 100 is shipped out of a maker. A user who wishes to guarantee properness of UII data produces cryptograph calculation result data through encrypting the RFID identification information and the UII data, when writing the UII data into the RFID tag 100, and stores the cryptograph calculation result data into a USER bank within the RFID tag 100.

Abstract: An electronic device system has an electronic device including at least one pair of an identifier and a validity flag. Identifier information and condition are registered into the identifier within the electronic device. When an access is made to the electronic device using an ordinary command, no response will be made since the validity flag is “irresponsive”. An identifier is transmitted to the electronic device using an identifier control command and if the condition is satisfied, the validity flag is set to be “responsive”, and thus operation to the electronic device becomes executable hereinafter. If the condition is not satisfied, the validity flag is set to be “irresponsive”, and thus no response will be made by the electronic device.

Abstract: In a traceability system, information of a change in distribution situation and form of an individual article, and information of identification of the individual article is collected from each of distribution sites, and collected information is strung in accordance with a predetermined rule. A flow of distribution is known and managed based on the strung information. This makes it possible to know a location from which the individual article is distributed and a route through which the individual article is distributed, thus allowing safety management of the individual article.

Abstract: Using a chrome plating bath containing organic sulfonic acid, plating is conducted by application of a pulse current to thereby form a crack-free lower chrome layer on a steel substrate. The lower chrome layer has a compressive residual stress of 100 MPa or more and a crystal grain size of from 9 nm to less than 16 nm. Subsequently, by application of a direct current, a cracked upper chrome layer is formed on the lower chrome layer, to thereby obtain a chrome plated part. The lower chrome layer imparts the chrome plated part with heat resistance and corrosion resistance, and the upper chrome layer imparts the chrome plated part with wear resistance and good sliding properties.
