A cap attached to an article having an opening, the cap including a cap body and at least one locking member that is slidably attached inward and outward from a center and comes in press-contact with an inner circumferential surface of the article to be locked to the cap body, in which the locking member slidably engages with other locking members on both sides, slides inward toward the center, thereby pushes the other locking members inward, and releases the locking.

An objective of the present invention is to efficiently perform a platform level test on a computer system comprising virtual machines that are automatically built according to predefined templates. A virtual machine test system according to the present invention creates a virtual machine according to a system template defining a combination of a network topology type of virtual machines and a role of each of the virtual machines, and performs a platform level test according to a test item defined for each of the combination (refer to FIG.).

Virtual machine test system, virtual machine test method

This object is aimed to provide an advertisement providing system, etc. that defines a web API that contributes to the creation of an advertisement attached webpage for making it possible to distribute referral fees of the advertisement. A system carries out processing while taking a session ID generated by an advertisement intermediary service () among a website (), a web API () and the advertisement intermediary service (), wherein the website () creates a webpage including a result of processing by the web API (), a link for acquiring a resource of advertisement information, and a link having as a parameter a session ID which is called on selection of an advertisement. And returns the webpage to a web browser (), and the advertisement intermediary service () records an advertisement information request in association with the session ID when the web browser () requests the advertisement intermediary service () for an advertisement information resource and then returns the advertisement information resource to the web browser (), thereby attaining the object.

Information providing method and advertisement providing method

There is a need to improve access speed for a file in a storage system that is provided with multiple storage units having different access speeds. The storage system () includes an access frequency acquiring part () that divides a past constant accessed data acquisition period into multiple unit periods, and obtains an access frequency for file stored in any of the multiple storage units (and), a similarity degree calculating part () that obtains, for each file, a similarity degree between the access frequency to the file for each unit period, and the access frequency to every other file for each unit period, a grouping process part () that groups one or more other files having a similarity degree equal to or higher than a predetermined value, in an identical group, and a file relocation part () that places a file belonging to the identical group into a storage unit () having a high access speed, when the file stored in the storage units (and) is accessed and there exists any other file within the identical group to which the file belongs.

Storage system, data relocation method thereof, and recording medium that records data relocation program

Structured documents written in a document structure definition language may be inconsistent with a predetermined document structure definition when they are encrypted partly or electronically signed. The document structure inspection method according to the present invention applies a document structure alteration rule to a document structure definition expressing the structure of such structured documents and effects conversion to generate a second document structure definition. The second document structure definition is then checked to determine whether it is consistent with a corresponding, predetermined document structure definition. The document structure alteration rule includes, for instance, a replacement rule for replacing an element contained in a document structure definition by another element, and an addition rule for adding an element to a location after the target document structure definition element.
