    • The present invention relates to a terminal structure. The terminal structure includes: a terminal having: a conductor layer containing at least one metal selected from gold, silver, and copper; a first layer containing nickel and phosphorus, laid on the conductor layer; a second layer having a smaller atomic ratio of nickel to phosphorus than the first layer and containing Ni3P, laid on the first layer; a third layer containing a first intermetallic compound of an Ni—P—Sn type, laid on the second layer; and a fourth layer containing a second intermetallic compound of an Ni—Cu—Sn type, laid on the third layer; and a solder layer on the fourth layer of the terminal. Ra2 is larger than Ra1, where Ra1 is a surface roughness of the third layer on the second layer side and Ra2 is a surface roughness of the third layer on the fourth layer side.

    • A general purpose engine is provided with an engine main body, a rotary shaft, and an axial gap type motor/generator. The rotary shaft is rotated by a driving force of the engine main body. The rotary shaft includes a first shaft part disposed on one side portion of the engine main body and a second shaft part disposed on another side portion of the engine main body. The axial gap type motor/generator is attached integrally to the second shaft part. The axial gap type motor/generator is provided with a power generating rotor that rotates integrally with said rotary shaft, and a stator that is attached to the engine main body. The stator is disposed on a side closer to the engine main body than the power generating rotor and at a remove from the power generating rotor.
    • 通用发动机设置有发动机主体,旋转轴和轴向间隙型电动机/发电机。 旋转轴由发动机主体的驱动力旋转。 旋转轴包括设置在发动机主体的一侧部的第一轴部和设置在发动机主体的另一侧部的第二轴部。 轴向间隙型马达/发电机与第二轴部一体地安装。 轴向间隙型马达/发电机具有与所述旋转轴一体地旋转的发电转子和附接到发动机主体的定子。 定子配置在比发电用转子更靠近发动机主体的一侧并与发电转子相脱离。

    • An integrated database system comprises a plurality of database systems connected to one another through a network, each of the plurality of database systems managing its own stored data independently of the other database systems and accessing the stored data in accordance with an access request, and an integrated database unit connected to the network. The integrated database unit includes a directory database which stores a correspondence between each of the data stored in the plurality of database systems and a database system in which each of the data is stored, a directory control unit which acquires, by using the directory database, directory information corresponding to target data of the accepted access request, a database identifying unit which identifies a database system, and a database control unit which issues, on the basis of the acquired directory information, an access request to the database system having the target data of the accepted access request. The database system includes a database server unit which accesses a database in accordance with the access request issued by the integrated database unit.
    • 集成数据库系统包括通过网络彼此连接的多个数据库系统,多个数据库系统中的每一个数据库系统独立于其他数据库系统管理其自己存储的数据,并根据访问请求访问所存储的数据,以及 集成数据库单元连接到网络。 集成数据库单元包括目录数据库,其存储多个数据库系统中存储的每个数据与存储每个数据的数据库系统之间的对应关系,目录控制单元通过使用目录数据库获取, 对应于所接受的访问请求的目标数据的目录信息,标识数据库系统的数据库识别单元以及数据库控制单元,其基于所获取的目录信息,向具有目标数据的数据库系统发出访问请求 的接受访问请求。 数据库系统包括数据库服务器单元,其根据由综合数据库单元发出的访问请求来访问数据库。
