    • An electron device comprising (i) a semiconductor element which includes a semiconductor region A of a first conductivity type, a semiconductor region B of a second conductivity type adjoining the region A, and a semiconductor region C of the second conductivity type adjoining the region A and isolated from the region B by the region A, and in which on a surface extending from the region B via the region A to the region C, a gate electrode is provided through an insulating film, (ii) means for holding a potential of the gate electrode so that a potential of minority carriers in a surface portion of the region A underneath the gate electrode may become lower than a potential in an inner portion of the region A, (iii) means for applying a forward bias voltage between the region A and the region B, and (iv) means for applying to the region C a potential by which a potential for the minority carriers becomes lower in the region C than in the region B. The electron device is capable of such operations as amplification, oscillation and memory under an extraordinarily low supply voltage, and is extraordinarily low in the power consumption.

    • The present invention discloses a method and system for making losses due to the counterfeiting of RF-ID tags to a minimum, enhancing the reliability of RF-ID tag read-out and improving the overall reliability of the RF-ID tag system. An ID reader for communicating by radio with the RF-ID tag and reading tag data from the RF-ID tag transmits the data read-out results to a terminal management server connected to the ID reader. The terminal management server decodes the error correction signal from the read-out result data, also extracts the identification number section from the tag, and decides whether or not that identification number is valid. When determined to be a valid identification number, an inquiry is made to the system operation server connected over the network to find out if that identification number was previously read out and if that identification number might be counterfeit. The system operation server then refers to the log database, the blacklist database and process transition rule, calculates the probability of counterfeiting and automatically sends a warning message to the related department when there is a high probability of counterfeiting.
    • 本发明公开了一种由于RF-ID标签伪造造成损失的方法和系统,提高了RF-ID标签读出的可靠性,提高了RF-ID标签系统的整体可靠性。 通过无线电与RF-ID标签进行通信并从RF-ID标签读取标签数据的ID读取器将数据读出结果发送到连接到ID读取器的终端管理服务器。 终端管理服务器从读出结果数据解码纠错信号,还从标签中提取识别号码部分,并判定该识别号码是否有效。 当确定为有效的识别号码时,对通过网络连接的系统操作服务器进行查询,以查明该识别号码是否先前已被读出,并且该识别号码可能是伪造的。 然后系统操作服务器引用日志数据库,黑名单数据库和进程转移规则,计算假冒概率,当假冒机率很高时,自动向相关部门发送警告消息。
