Abstract: A system smoothly performing information processing is realized by dynamically making a decision, when it becomes necessary for an agent currently located at a platform to make use of another platform, with regard to whether to cause the agent to move to the other platform or cause the agent to cooperate with another agent that exists at the other platform. The dynamic decision is made in response to situations, resulting in enabling the unified utilization of mobile and stationary agents. The decision of using either movement or cooperation is typically made based on platform information and agent information. Even if planning changes the plan of an agent and regardless of what agent is using which platform's resources, it is possible to easily establish whether movement or cooperation is to be used, based on the platform profile and agent attributes. Such a system can perform information processing in response to changing situations.

Abstract: Systems and methods for using a main script program include a function that prompts a user to enter an input script program while a main script program executes. An ACL (Access Control List) defines commands used by the input script program. When a user executes the main script program, a prompt function prompts the user to enter the input script program. Program execution continues and the user's computer determines whether the input script program is executable based upon the ACL contained in the main script program. Accordingly, the input script program may only execute a specified range of authorized commands.

Abstract: A mobile agent mediates cooperation among schedulers by executing a cooperation protocol. For heuristics such as strategies and the order in which variables are decided, which are used as criteria of selecting the value of a variable from candidates, when the heuristics are to be built into a solving method of a constraint satisfaction problem, processes with regard to these heuristics are so substantially localized as to be capable of parallel execution. These processes capable of parallel execution, as autonomous operations of different mobile agents, can be under modeling in natural form, resulting in easy installation. This facilitates software construction for reflecting the heuristics in a solving method of a constraint satisfaction problem, as well as improves the maintainability and extendibility of software.

Abstract: An apparatus collects information stored in a host computer through a network. A correspondence acquirement unit acquires a correspondence between an information identifier of requested information and host identifiers of a plurality of host computers each of which stores the requested information. A first decision unit decides at least one host computer to retrieve the requested information by referring to the correspondence. A second decision unit decides a retrieval method used for each host computer decided by the first decision unit from a plurality of retrieval methods. A retrieval unit indicates retrieval of the requested information based on the retrieval method decided by the second decision unit and each host computer decided by the first decision unit.

The table stores a plurality of transfer address data corresponding to each one of the destination data.

Abstract: A system and method for processing a large constraint satisfaction problem quickly, including a subset generating module (1), which divides a set of alternatives provided for a plurality of parts of a given problem into a plurality of subsets, such that each subset has not more than two alternatives for each part. For each subset generated by the division, a solution calculation module (2) finds a solution by calculating combinations of alternatives satisfying a constraint between alternatives selected for each two parts. The calculation of a solution for a subset, such that each subset has not more than two alternatives for each part, requires a very short period of processing time, even if the parts are many. Thus, the sum of the times required for finding a solution for all the subsets is much shorter than the time required for finding a solution for the original problem without such processing.

Abstract: A system and method for executing a plurality of programs for control of objects, in which states of the objects are first transmitted to the programs. The programs to which the states of the objects are transmitted are then independently executed. The executed results are evaluated, modified and then transmitted to the objects. Thereby the structure of the programs can be simplified, sequential development of the programs can be realized, and program maintenance can be facilitated. Further, a fault tolerance to bugs on software can be enhanced and perfect operation of the software functions can be realized.

Abstract: It is an object of this invention to provide a data processing system, computer network, and data processing method which enable alternate programs to run without degrading the system processing performance. When control of a program executed by the executing means 1 reaches a pre-defined execution checkpoint, the notifying means 3 issues an interrupt instruction and the sending/receiving means 4 sends this instruction to other nodes. In a node where this interrupt instruction is received, the interrupt controlling means 5 causes the executing means 1 to interrupt processing if program control has not yet reached a pre-defined execution checkpoint in the node.

Abstract: When inexecutable event occurs, an event format conversion rules table is referred to in order to convert the format of the event, then the communication message including the converted event is transmitted through a network. If the communication message is received through the network, the converted event is re-converted into an event that has an executable format by referring to the event format conversion rules table.An event filter refers to an event filter table that has processing necessity information for each event and sends only an event that needs to be processed to an event processing portion. Even if the local system cannot execute an event, the event is transmitted to another system through a communicating portion.

Abstract: A high-reliability file system which surely keeps multiple file data on one drive even if some drives have failed. If renewal of a plurality of blocks of a disk by data in a buffer is necessary, a buffer manager renews the disk by all the data in the buffer which are to be renewed in the future. Flush management is carried out by the drive and the buffer manager. If another drive is "examining" or "renewing" when a flush (renewal) is to be executed, a sequencing means temporarily restrains the buffer manager from starting the flush.

Abstract: In a method of testing a color cathode ray tube, an electron gun assembly is energized to emit electron beams and only a horizontal deflection magnetic field is applied to the electron beams so that a line image is displayed on a screen. A degaussing coil is located in front of the panel and a degaussing magnetic field having a frequency the same as that of a commercial power source. Thereafter, the degaussing coil is moved in a direction away from the panel and is deenergized when the coil is removed from the panel at a predetermined distance. A vertical deflecting coil is energized to display an image and a picture quality of the tube is tested.

Abstract: A program execution system for a program having one or more versions includes a program storing unit for storing a plurality of program versions, an exclusive condition storing unit for storing invocation data for abnormal termination of a process, an executing unit for selecting a version form among one or more versions of the program corresponding to the process to be invoked, a detecting unit for detecting an abnormality of the process during the execution, and an updating unit for transferring the invocation data. If the currently executing code version fails, the program execution system selects another version for execution, thus minimizing system interruption and improving system reliability.

Abstract: A method for manufacturing a curved rubber pipe is provided with a guide member (3) arranged concentrically with a mandrel (2, 402). A straight rubber semi-finished product (4) of an unvulcanized or semi-vulcanized rubber is inserted into the guide member (3). A die lubricant can be applied only to the inside of the rubber semi-finished product (4) over its whole length. The rubber semi-finished product (4) is fitted on the mandrel (2, 402) by pushing the product by a head (7) mounted on a leading end of an arm (6). One end of the curved rubber pipe (1) is gripped after vulcanizing by a gripping member (10) and is extracted from the mandrel (2, 402). By this method, it is possible to fit and smoothly extract the rubber semi-finished product (4). The method can also easily be automated.
