Abstract: In a communication terminal using UIM, when a message disabling use of a content is received not by a communication terminal containing the content to disabled, but by another communication terminal containing the same content, the content stored in a storage unit of the communication terminal which has received the message is not disabled. Mobile phone 100-1 using UIM stores a program in correlation with a telephone number stored in the UIM. When mobile phone 100-1 receives a management message to delete a program, mobile phone 100-1 interprets the content of the management message. Mobile phone 100-1 obtains a telephone number from the UIM, and deletes the content stored in correlation with the telephone number according to the management message interpreted.

Abstract: Data indicating information relating to a mobile communication terminal is sent from the mobile communication terminal at a designated opportunity and the status of the mobile communication terminal is managed by a server apparatus. An AP managing server 500 sends to a mobile telephone device 600 an identifier indicating a timing for sending information relating to an application program to the AP managing server 500. When the identifier indicating the timing for sending information relating to an application program to the AP managing server 500 is received, the mobile telephone device 600 sends the information relating to the application program to the AP managing server 500 on the basis of the timing indicated by the received identifier.

Abstract: A pressure-sensitive adhesive double-coated sheet comprising a substrate, a pressure-sensitive adhesive layer (A) formed on one side of the substrate and a pressure-sensitive adhesive layer (B) formed on the other side of the substrate, wherein at least the pressure-sensitive adhesive layer (A) is formed with a pressure-sensitive adhesive comprising a butyl rubber as base material, and after the pressure-sensitive adhesive double-coated sheet is allowed to stand at 60° C. for five days while being placed between a moisture vapor-permeable waterproof sheet attached to the adhesive layer (A) and an aluminum plate attached to the adhesive layer (B), an expansion coefficient of the moisture vapor-permeable waterproof sheet is 0.5% or less. The pressure-sensitive adhesive double-coated sheet can allow the moisture vapor-permeable waterproof sheet to less expand over time when attached between the moisture vapor-permeable waterproof sheet and the adherend in a waterproof airtight structure of a construction.

The first guide is formed of a leaf spring and configured to urge the retaining member toward the second guide.

Abstract: In a communication terminal using UIM, when a message disabling use of a content is received not by a communication terminal containing the content to disabled, but by another communication terminal containing the same content, the content stored in a storage unit of the communication terminal which has received the message is not disabled. Mobile phone 100-1 using UIM stores a program in correlation with a telephone number stored in the UIM. When mobile phone 100-1 receives a management message to delete a program, mobile phone 100-1 interprets the content of the management message. Mobile phone 100-1 obtains a telephone number from the UIM, and deletes the content stored in correlation with the telephone number according to the management message interpreted.
