Disclosed herewith is a terminal for receiving data distributed from a host computer. The terminal includes a database for storing data distributed from the host computer and a schedule manager for managing the schedule of the terminal. Upon receiving an update request for the data stored in the database, the terminal extracts a time band in which the usage frequency of the terminal is kept low as an updatable time through the schedule manager and sends an update request to the host computer in response to the received request. The terminal calculates a processing time required to update object data, as well as a value denoting the usefulness of the object data according to the update information received from the host computer and including the object data, then decides a processing order for the object data according to the processing time and the usefulness value calculated respectively for the object data, thereby updating the data stored in the database according to the decided processing order. Useful data is updated preferentially in the time band in which the usage frequency of the terminal is low.

A map display method whereby the contents of a road map displayed can be easily and clearly grasped regardless of the running conditions of a vehicle. In a summarized map displayed on a display screen, an area including a vehicle position, a destinationand a guide routebetween them is displayed in simplified fashion. At a position far from the destination, as shown in FIG.A, a summarized map of a wide area is displayed and objects including a roadand a facilityare limited to a greater degree. With the approach of the vehicle positionto the destination, as shown in FIG.B, the contraction scale is decreased and a summarized map of a middle area is displayed, while at the same time increasing the objects displayed. With a further approach of the vehicle positionto the destination, as shown in FIG.C, a narrower area is displayed in summarization, while at the same time displaying substantially all the objects, thereby making it possible to grasp the neighborhood of the destinationin detail.

Map display method

An updated part of map data is delivered while suppressing unwanted communication traffic and preventing contradiction in the updated map. A map delivering server () comprises a map data storage section () storing link data including the update dates and times and update infection range for each link, a network IF section () for receiving from a navigation terminal () a map delivery request containing the requested area of map delivery and the previous request data and time of map delivery of the requested area, and a map element search section () for searching the map data storage section () for the link data associated with the update infection range including the link at least a part of which belongs to the requested area of the map delivery request and associated with the update date and time later than the previous request date and time contained in the map delivery request. The link data found by the map element search section () is sent to the navigation terminal () through the network IF section ().

In a semiconductor integrated circuit device and a method of designing the same, design information about circuit cells each having a desired function are described as objects according to selected purposes. The pieces of design information are registered in a cell library as cell information capable of forming any of substrate potential fixed cells and substrate potential variable cells. Further, a data sheet common to the substrate potential fixed cell and the substrate potential variable cell is offered to a user, so that the user is able to make a selection according to the user's purposes. The substrate potential fixed cells and the substrate potential variable cells are mixed together on a semiconductor chip so as to be properly used according to the functions or the like of circuit portions in which the cells are used.

A controller of a navigation terminal (navigation apparatus) is configured to find a plurality of paths from a current position of a vehicle and a destination based on a plurality of different and prioritized path-finding conditions, respectively, and causes a display to show the plurality of paths which includes a navigating path found on the basis of a top-priority path-finding condition and at least one alternative path found on the other path-finding condition(s). In response to detection of deviation of the vehicle, the priority assigned to a path-finding condition based on which a specific alternative path along which the vehicle is running is changed into a top priority, and path-finding operation is performed again for paths from the current position of the vehicle to the destination to show a new navigating path and at least one new alternative path in the display.

A car navigation system by which a user can easily grasp a drop-in target in the course of a route. In a summary road map displayed in a two- or one-window display representation, contents of a two-dimensional road map is properly selected and simplified, roads are made linear, roads connected to an intersection are made orthogonal so that the user can easily see it, the position of a vehicle is expressed by a mark, and even the running route is expressed with a predetermined color or the like. Accordingly, the system offers the user such a display form as able to easily refer to. When the user specifies a target at which the user wants to drop in, the drop-in target is displayed at a corresponding position on the summary road map in the form of a land mark.

For interactive operation between different enterprises or organizations, it is necessary to provide high-quality map information by not only displaying the results of retrieval from the map information servers of those organizations in a superimposed manner but also performing distributed retrieval on the basis of a relationship matched in sense between the servers. Thus, an interface is provided in which the optimum relationships between objects provided from the map servers distributed on the Internet environment and objects defined by a desired application are generated and a work of confirmation and modification by a user can easily be done. Thereby, a cost required for a complicated relating procedure indispensable to an interactive operating system is reduced.

Map information supply device for mobile units

A portable terminal with the function of walking navigation. The portable terminal displays information on its narrow screen so as to make it easy for the user (walker) to understand and realize an interface that enables the user to understand inputs of retrieving conditions intuitively, thereby saving the input labor. Assume now that a user (walker)is lost while walking towards a destination. In such a case, the present invention enables necessary information to be compressed, for example, so as to display both direction and distance to the destination from a present place with an orientation and a length of an arrow on a small screen and further so as to match the orientation of the arrow with the direction of the destination in the actual space. If the user (walker)specifies a compressed information item, orfor inquiry, the present invention controls so that the arrow always points the direction of the destination corresponding to each of those compressed information items, and. The condition of retrieval can also be set by turning, for example, the tip of the portable terminal directly in the desired direction h, or

Portable terminal with the function of walking navigation

Semiconductor integrated circuit device

A portable terminal has a function of walking navigation. The direction of a destination is displayed by an indicating arrow that always points in the direction of the destination. In the navigation processing, the user enters data to select a menu and/or set retrieving conditions on the setup screen. At first, the user gets the location information of the portable terminal, represented by a latitude/longitude or coordinates and an altitude, for example. Then, the user gets the direction information of the portable terminal, which is the direction of the tip of the portable terminal as determined by a compass, a gyro, or a clinometer. The location information and the direction information are set as terminal information for the retrieving conditions. The system controls retrieving of the database and retrieves the information corresponding to the selected menu, such as route guidance.
