摘要:
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.
摘要:
A semiconductor memory includes a word line driving circuit whose output terminal is coupled to one end of each word line of a memory array, and also an auxiliary driving circuit which drives the other end of the word line upon receiving a selection signal transmitted to the other end of this word line. The auxiliary driving circuit comprises a level detector circuit which is dynamically driven by a timing signal, and a driving element which is driven by an output of the level detector circuit to drive the other end of the word line. When the word line is to be reset, the output of the level detector circuit is set at a level which brings the driving element into an "off" state. The auxiliary driving circuit of this arrangement permits the other end of the word line to change to a selection level quickly and to be reset quickly.

An updated part of map data is delivered while suppressing unwanted communication traffic and preventing contradiction in the updated map. A map delivering server (10) comprises a map data storage section (102) storing link data including the update dates and times and update infection range for each link, a network IF section (101) for receiving from a navigation terminal (20) 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 (103) for searching the map data storage section (102) 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 (103) is sent to the navigation terminal (20) through the network IF section (101).
摘要:
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.
