    摘要： According to a method of erasing data in a non-volatile semiconductor memory device, block-round type overerase verify is performed. Specifically, overerase verify and write back are performed sequentially from a first address to a last address. That is, even when a write back pulse is applied after a certain address is selected and verify is performed, address increment from one address to another is performed, regardless of whether verify has been performed or not. Therefore, it is not that the same address is cumulatively rewritten, but write back to a memory cell corresponding to a defective address is sequentially and gradually performed. Accordingly, as write to a memory cell in an overerased state can evenly be performed, influence by off-leakage is suppressed, and a memory cell having threshold voltage distribution with less variation can be implemented.

    摘要翻译： 根据擦除非易失性半导体存储器件中的数据的方法，执行块式过程验证。 具体来说，过度验证和回写是从第一个地址到最后一个地址顺序执行的。 也就是说，即使在选择了某个地址并进行验证之后应用写回脉冲的情况下，执行从一个地址到另一个地址的地址增量，而不管是否执行了验证。 因此，不是相同的地址被累积地重写，而是顺序地逐渐执行写入与缺陷地址对应的存储单元。 因此，能够均匀地进行对高电平状态的存储单元的写入，能够抑制泄漏的影响，能够实现具有小变化的阈值电压分布的存储单元。

    摘要： When a data write sequence is started, initially, write data is latched in a data latch circuit corresponding to one memory mat. Then, a program pulse is applied to the memory mat, and data read from a memory cell, which is a data write target bit in the memory mat, is performed. Thereafter, verify determination of the memory mat is performed. After a verify operation for the memory mat is completed, a program pulse is applied to another memory mat, and a verify operation for another memory mat is performed.

    摘要： A bearing assembly includes an IC tag with information to be reliably exchanged between the IC tag and an external reader/writer, and a rolling bearing including outer and inner races and rolling elements disposed between the outer and inner races. The IC tag communicates with the external reader/writer device without contacting the reader/writer device, is attached to a metal member of the rolling bearing, includes a tag antenna, and is configured so information can be exchanged between the tag antenna and a reader/writer antenna of the reader/writer device by forming a closed magnetic circuit between the tag antenna and the reader/writer antenna. The IC tag is received in a hole in a metal member surface. The tag antenna includes at least two protrusions facing the opening of the hole and arranged so magnetic fluxes leaving/entering the protrusions pass inside the edge defining the hole opening and extend outside the hole.

    摘要： A searchable encryption resistant to frequency analysis. A conversion rule management device generates a conversion rule table associating a search keyword with a conversion keyword group. Based on the conversion rule table, a data registration device generates registration data associating encrypted data with an encrypted keyword, and registers the registration data in a server device. An information processing device obtains from the conversion rule table a conversion keyword group associated with a specified search keyword, generates an encrypted keyword group, and requests a data search by specifying the encrypted keyword group. Using as a search key an encrypted keyword included in the encrypted keyword group, the server device searches for encrypted data associated with the search key, and returns searched encrypted data. The information processing device decrypts the searched encrypted data, and outputs as a search result search data obtained by decryption.
