To eliminate interruption of a service used by a user and reset of communication caused by switching of an operating server such as a process migration or the like. On receiving a session migration start request, server/network cooperation control means 2 issues an operating server-switching control start notification to an operating server switching control means 3 (step S702). On receiving the operating server switching control start notification, the operating server switching control means 3 switches an operating server. Next, on receiving an operating server switching control completion notification, the server/network cooperation control means 2 sends a connection destination target network-switching request to a connection control means 4 (step S707). The connection control means 4 switches the connection destination target network of the user corresponding to a user name whose connection destination target network is to be switched, from a target network including a main server to a switch destination target network including a backup server (step S708).

Disclosed is a network system comprising: a plurality of routers 704 and 705 connected to each other through a network; pseudo redundant configuration setting means 702 and 703 which are connected respectively to the routers and which perform a communication using a redundancy protocol with respective routers; and association control means 701 connected to the pseudo redundant configuration setting means 702 and 703, wherein when a server 716 is a backup server and its backup state needs to be maintained, the pseudo redundant configuration setting means 703 issues a signal for maintaining a standby state to the router 705, and when servers are switched between a standby state and operating state, the association control means 701 transmits a switching instruction for switching between a standby state and operating state to the pseudo redundant configuration setting means 702 and 703.

In application of a green-house effect, under such a concept as to collect solar energy passively into the house and to exhaust moist air passively from the house, an all weather passive-type solar Ogako drying house which is available for all day through a year was made up improving an agricultural vinyl-house in which Ogako is dried continuously during carriage on the belt conveyors due to solar energy and auxiliary heat, and then moist air yielded when drying Ogako is exhausted through an insulated cylinder. In this case, Ogako means sawdust or tipped small particles of wood which is raw material in order to produce a woody pellet fuel.

Provided is a thin client system that automatically allows two types of user terminals, a network-boot-type user terminal and a screen-transfer-type user terminal, to share the same execution environment. A screen-transfer/network-boot switching system serves as a server function switching device used in the thin client system, including a server function switching section and a terminal process proxy execution section. The server function switching section accepts a connection request from the user terminal, and determines attribute of the user terminal. If the user terminal is the network-boot-type user terminal, the boot image transfer section transfers a boot image to the user terminal. If the user terminal is the screen-transfer-type user terminal, the boot image transfer section transmits a boot image to the terminal process proxy execution section. Moreover, the terminal process proxy execution section transmits screen information to the user terminal.

A method, system and program processing unit for a robot, by which the safety during execution of a program is improved. The program processing unit comprises a program interpreter, a command rejection device and a command execution device. When the program interpreter sends a command in a program to the command rejection device, the command rejection device searches a command rejection rule storage section for a command rejection rule corresponding to the command, and if the rule is detected, retlieves input values from one or more sensors and the source information of the program from a source information storage section, judges command rejection conditions included in the rule based on the sensor information, source information, the command and its parameters, dismisses the command when the conditions are met, and sends the command to the command execution device when the conditions are not met.

In a distributed processing in which multiple operation transportation methods can be used, a method is proposed which efficiently selects an operation transportation method in accordance with conditions of the distributed system. In view of this, a first computer is provided which includes: a first operation transportation portion which conducts multiple transportation methods that transports, for example, processes to a computer to execute them; a second operation transportation portion; and a selection information storing portion storing information used for selection from the multiple transportation methods. Further, a second computer is provided which includes a first operation receiving portion that conducts operations in accordance with the multiple transportation methods. The first computer includes a transportation request portion which detects information from the selection information storing portion for selecting a transportation method that is operable for the second computer and which selects the first operation transportation portion based on the detection result, and the first operation transportation portion selected by the transportation request portion transports, for example, a process to the first operation receiving portion of the second computer.
