Abstract: In a service providing system, a first database holds plural kinds of balloon data, in which each of plural pieces of three-dimensional real space range information and an identifier for identifying the three-dimensional real space range information is related, and a second database holds a service execution file in which each of plural pieces of three-dimensional space region information related to each identifier and service information in each three-dimensional space region are related. An extracting unit extracts, using position on a user terminal and an identifier, a service execution file corresponding to a three-dimensional space region. A service execution processing unit performs an executing process of a service corresponding to service information held in the extracted service execution file. The service system provides various kinds of services information at any time, effectively use the hardware, and limit the access. The user obtains service information available in a wide area.

Abstract: A SAW device comprises a single crystal piezo-electric strate (made, for example, of LiTaO3 or LiNbO3), and an interdigital transducer (IDT) formed of a material mainly containing Al and disposed on the piezo-electric substrate. The piezo-electric strate contains an additive (for example, Fe, Mn, Cu, Ti), and an orientation rotated by an angle in a range of 42° to 48° (more preferably 46°±0.3°) from a Y-axis toward a Z-axis about an X-axis. The IDT presents a normalized thickness h/? (h: thickness of electrode, and ?: spacing between digits of the IDT) of 7% to 11%. A more appropriate substrate cut angle can be shown for the SAW device which employs a piezo-electric substrate containing an additive, to improve the electric characteristics thereof.

Abstract: An information providing service method comprising the steps of selecting an object displayed on a map in a user terminal, transmitting coordinate information relating to an object selected in the terminal and display object attribute information representing attributes of service information to be provided by the object to a server connected to the terminal over a network, transmitting spatial range information, attribute information and a URL based on the transmitted coordinate information and display object attribute information from the server to the terminal, and displaying an information bubble along with the object at a position indicated by the transmitted spatial range information on a display unit of the terminal, whereby the service information is provided such that the service information is linked with map information of the terminal to the user, and the information bubble is displayed in an appropriate size on the map information.
