摘要:
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.

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.

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.

Disclosed is a polyoxyalkylene derivative which is useful for a carboxyl group-containing polyurethane resin, can easily introduce a carboxyl group into a polyurethane resin skeleton, and has a low melting point or is in a liquid state at normal temperature. The polyoxyalkylene derivative is represented by formula (I): ##STR1## wherein R.sub.1 represents a hydrogen atom or an alkyl group having from 1 to 3 carbon atoms; R.sub.2 represents an alkylene group having from 1 to 6 carbon atoms or an arylene group having from 6 to 8 carbon atoms; A represents an alkylene group having from 4 to 7 carbon atoms; B represents an alkylene group having from 2 to 6 carbon atoms; l represents from 0 to 2; m represents from 0.1 to 35; n represents from 0.1 to 50; and 0.5
摘要:
Multimedia data in an object structure include entity objects and relation objects, wherein each entity object has data representing a media element as internal data, and each relation object represents a relation between the entity objects. A relation object is searched according to information specified by a search command, and a searched relation object and internal data of an entity object related thereto are displayed on the screen of a display unit as a set of display elements. To generate a digest of the multimedia data, a matching between a structure portion of a user model and a structure portion of a system model is examined. The user model is generated according to a request of the user and arranged in layers, while the system model has been previously generated. The multimedia data are arranged in layers according to the importance of respective data elements constituting the multimedia data. According to an examination result, a user model structure portion is selectively replaced by a system model structure portion, and the replaced user model is adjusted so as to display the same.

A drawing processing system includes file storage equipment for storing drawing data in the form of pages through division of the drawing data, a memory for storing coordinate correcting values for managing pages in a continuated manner, and a temporary memory for storing page data for executing drawing edition processing. The drawing data are transferred from the file storage equipment to the temporary memory in a continuated manner, while the coordinate correcting values being added thereto. A joined drawing is prepared by combining together the pages along the boundaries thereof on the basis of the drawing data as transferred and by erasing the boundaries between the connected pages. Graphic edition processings such as displacement, joining, separation or the like can be then performed in the joined drawing.
