摘要： The prior art information system could not migrate a file in a file sharing system provided by a file storage to a plurality of cloud storages having different forms of connection and different properties, and therefore, could not manage the files via a single Stub information. The present invention provides a data mover program in a file storage to select one or more migration destination cloud storages based on a migration policy, a connection information table of cloud storages and a property information table of cloud storages. Then, a Stub information of the migrated file is created, and an identification information of the file in the cloud storage is stored in a file information table. When access occurs from a client to a file storage, the data mover program downloads a file from the cloud storage stored in the file information table corresponding to the Stub information and provides the file to the client.
摘要翻译：现有技术的信息系统不能将由文件存储器提供的文件共享系统中的文件迁移到具有不同形式的连接和不同属性的多个云存储器中，因此无法通过单个存根信息来管理文件。本发明提供一种文件存储器中的数据移动器程序，用于基于迁移策略选择一个或多个迁移目的地云存储，云存储的连接信息表和云存储的属性信息表。然后，创建迁移文件的存根信息，将云存储中的文件的识别信息存储在文件信息表中。当从客户端到文件存储进行访问时，数据移动器程序从与存根信息相对应的文件信息表中存储的云存储中下载文件，并将该文件提供给客户端。

摘要： An electromagnetic flowmeter using a square wave excitation method includes a differential amplifier which outputs a detection signal; an analog-digital converter which converts the detection signal into a digital detection signal; a timing control circuit which generates a sampling signal for sampling the digital detection signal; an calculation unit which executes a flow rate calculation process and a abnormality judging process at a same time. The flow rate calculation process acquires a flow velocity output signal by sampling the digital detection signal in a flat portion in a positive/negative excitation section. The abnormality judging process acquires a differential output signal by sampling the digital detection signal in a rising/falling portion in the positive/negative excitation section, and obtains a differential noise from the flow velocity output signal and a differential output signal, and judges abnormality of the exciting current by comparing a differential noise with a detection threshold level.

摘要： Each time the file access request is received, it is discriminated whether there is an ACL which corresponds with the file system of the type following the switching in the file designated by the file access request. In cases where the judgment result is that there is no such ACL, an ACL which corresponds with the file system of the type following the switching is generated on the basis of an ACL which corresponds with the file system of the type prior to the switching which is associated with the designated file, and the ACL thus generated is used to control access in accordance with the received file access request.
摘要翻译：每当接收到文件访问请求时，区分是否存在与由文件访问请求指定的文件切换之后的类型的文件系统相对应的ACL。在判断结果是不存在这样的ACL的情况下，根据与切换前的类型的文件系统对应的ACL来生成与切换后的类型的文件系统对应的ACL，与指定的文件相关联，并且由此生成的ACL被用于根据接收到的文件访问请求来控制访问。
