Abstract: An image processing apparatus includes an image data acquiring unit that acquires image data, and a transmitting unit that, if a first destination specified as a destination of the image data by a user is not safe, transmits the image data to a second destination different from the first destination, and transmits information indicating the second destination to the first destination.

Abstract: A piezoelectric stack includes a porous resin sheet, and a surface coating layer disposed on an exterior surface of the porous resin sheet, the exterior surface including at least one of a front surface and a back surface of the porous resin sheet, the surface coating layer having a volume resistivity of not less than 1×1013 ?·cm, the porous resin sheet and the surface coating layer having different elastic moduli.

Abstract: A collective system for billing management of each game machine installed in shops or the like via communication network. A limit is set to the usable number, while the game machine is ensured continuous use as long as it is properly used and the billing is carried out regularly during the continuous use on a pay-per-use basis. The play count is counted up every time one game is played, and when the play count has reached or exceeded a count limit, the use of the game machine is restricted. The game machine is connected to a billing server via a communication network. The billing server includes a count limit renewing unit which renews the count limit of the game machine that has transmitted billing information, and transmits the new count limit back to the game machine every time the billing server receives the billing information from the game machine.
