    • An imidazole-isocyanuric acid adduct having the following general formula is disclosed: ##STR1## wherein R.sub.1 is a member selected from the group consisting of a hydrogen atom, a .beta.-cyanoethyl group and a .beta.-[3,5-diamino-S-triazinyl-(1)]-ethyl group, R.sub.2 stands for a monovalent hydrocarbon group having up to 17 carbon atoms, R.sub.3 is a member selected from the group consisting of a hydrogen atom and an alkyl group having up to 4 carbon atoms, with the proviso that when R.sub.1 is a hydrogen atom, R.sub.2 is a methyl or phenyl group and R.sub.3 is a hydrogen atom and when R.sub.1 is a .beta.-cyanoethyl group, R.sub.2 is a phenyl group and R.sub.3 is a hydrogen atom, and n is a number of from 0 to 2.This adduct has peculiar characteristics not possessed by ordinary salts. Namely, the adduct is stable in water, and it decomposes in a solvent or under heating. The adduct is valuable as a curing agent for epoxy resins, and it can be utilized for purification of imidazoles.
    • 公开了具有以下通式的咪唑 - 异氰脲酸加合物:其中R 1是选自氢原子,β-氰基乙基和β-[3,5-二氨基-S- 三嗪基 - (1)] - 乙基,R 2表示具有至多17个碳原子的一价烃基,R 3是选自氢原子和具有至多4个碳原子的烷基的成员,其中 条件是当R1是氢原子时,R2是甲基或苯基,R3是氢原子,当R1是β-氰基乙基时,R2是苯基,R3是氢原子,n是 从0至2.该加合物具有普通盐不具有的特有特性。 即,加合物在水中稳定,在溶剂中或加热下分解。 加合物作为环氧树脂的固化剂是有价值的,可用于咪唑的纯化。

    • A semiconductor memory device includes a memory which comprises a confidential information area storing confidential information and a flag. A controller reads the flag from the memory when instructed to erase or write data in the confidential information area, determines whether the flag is set, erases or writes data in the confidential information area when the flag is clear, and abandons a process requested by an erase or write instruction when the flag is set. An authenticator uses data in the confidential information area to execute an operation for authentication. A management information area may store management information for associated pages. The flag may include a bit string and a complementary bit string to improve reliability of the flag. The confidential information area may store dummy data when the memory is used for uses other than an application with an authentication function, so no problem arises using a normal controller.
    • 半导体存储器件包括存储机密信息区域和标志的存储器。 当指示擦除或写入机密信息区中的数据时,控制器从存储器中读取该标志,当该标志清除时,确定在机密信息区中是否设置,擦除或写入数据,并放弃由 设置标志时擦除或写入指令。 验证者使用机密信息区域中的数据来执行认证操作。 管理信息区域可以存储关联页面的管理信息。 标志可以包括位串和互补位串,以提高标志的可靠性。 当存储器被用于除具有认证功能的应用程序之外的使用时,机密信息区域可以存储虚拟数据,因此使用普通控制器不会出现问题。
