Abstract: The single sign-on is implemented without requiring knowledge of a lower layer such as HTTP and HTML by using a single sign-on module which stores knowledge to store single sign-on and a single sign-on server which analyzes log-in communication of an EIS (Enterprise Information System) and selects and executes an applicable single sign-on module. Since the single sign-on can be implemented without requiring knowledge of a lower layer such as HTTP and HTML from a system engineer, the single sign-on can be implemented in a short period and at low cost.

Abstract: There is provided a method of efficiently accessing information located on Web pages in a ubiquitous environment such as a home, an office and on a travel. A gateway server is located between a client and Web servers for providing the contents. The gateway server traps a request of a browser operating in the client and records an access history. On the access records, the display form of a link in the contents is changed, and the service of managing the accessed information is presented to the client. Further, the user may optionally set an attribute to the contents and change the display form of the accessed link according to the set attribute.

Abstract: The search method comprises a first step of receiving a service inquiry request; a second step of making an inquiry about policy information of a client 100 who requested service and obtaining the policy information of the client 100 from a policy database 103; a third step of sending a request to search for a server matching the service sought after by the request and obtaining information showing the server matching the service from a registry 109; a fourth step of extracting a server meeting the policy information of the client obtained in the second step out of servers related to the information obtained in the third step; and a fifth step of transmitting information showing the server extracted in the fourth step to the source of the request to search for service.

Abstract: In a computer system including a plurality of computers interconnected through a network, a specific computer A in the computer system manages the computer resource information and the operating condition information such as for a CPU, a file and a memory and the user resource information such as file data and a program of each computer of the computer system. When a user issues a request from a computer C to log in to the computer system, the request is reported to the computer A, and the information related to the user is returned to the computer C with reference to the user resource information held by the computer A. Then, the computer C acquires the file and the usable program held by the user in the computer system and executes a process, whereby the whole system can be used as resources of each user.

Abstract: Each of a plurality of simulation programs is linked with a data conversion library and is executed as a simulation process. A data conversion process is executed in correspondence with each simulation process. In exchanging data resulted from simulation by the simulation process of one of the simulation programs with simulation processes of the other simulation programs, the data conversion process provided for a sending simulation process determines a receiving simulation process to which the data is to be sent, and sends the data to the data conversion process corresponding to the receiving simulation process. The data conversion process for the receiving simulation process performs data conversion for absorbing difference between the base of the sending simulation process and the base of the receiving simulation process, and transfers the data after the conversion to the receiving simulation process.

Abstract: A styrenic resin plate excellent in ink-acceptability and paintability is manufactured by applying an emulsion coating comprising a hydrophobic synthetic resin, a hydrophilic polymer, a finely pulverized inorganic filler and water or an emulsion coating obtained by adding to a mixture of said components a solution of an isocyanate compound possessed of at least two functionalities in a hydrophobic solvent to one side or both sides of a styrenic resin plate, preferably a foamed plate of styrenic resin, uniformly by means of a roll coater, a spray coater or the like and drying the applied coat of emulsion coating to form a surface layer on said resin plate. The present styrenic resin plate excellent in ink-acceptability, paintability is used as displays, advertizing boards, etc.
