Abstract: A moving-body light-emitting device for a vehicle includes: a light source including a light-emitting element; a substrate on which the light source is provided; a first lens that covers the light-emitting element and includes a curved surface that transmits light emitted from the light-emitting element, the curved surface including a first curved surface and a second curved surface; and a reflective surface that covers the first curved surface of the first lens and reflects the light transmitted through the first lens. The second curved surface of the first lens is not covered with the reflective surface, and transmits the light reflected by the reflective surface.

Abstract: A device control system includes: an instruction device that controls operation of an electrical device which requires key information to operate; and a terminal device that communicates with the instruction device. The terminal device includes a terminal communicator that: receives, from the instruction device, identification information for identifying the electrical device; and transmits, to a server, the identification information and use request information indicating a request for using the electrical device. The instruction device includes: an instruction communicator that receives, from the server, the key information and use period information indicating an available time period of the electrical device; and an instruction controller that, when the key information and the use period information are received via the instruction communicator, activates the electrical device for the available time period indicated in the use period information.

Abstract: A telephone directory database is established in a mobile phone terminal. When a calling operation is executed in the mobile phone terminal, data included in the telephone directory database is sent out into the data network. A server computer in the central office may receive the data. The received data is registered into a database for backup data in the server computer. The backup data for the telephone directory database is reliably prepared in the server computer in this manner. A user of the mobile phone terminal is allowed to easily reestablish the telephone directory database in a new mobile phone terminal based on the backup data.
