摘要:
A plurality of virtual client processes for accessing a server are simultaneously operated on test execution terminal, when accessing the server by each virtual client process, respectively unique virtual network addresses are set, a source network address in a transmission packet is rewritten into the set virtual network address from an actual network address, a destination network address in a reception packet from the server is rewritten into the actual network address from the virtual network address, and this packet is transferred to the client with this virtual network address set therein. Load tests of accesses to the server from a multiplicity of client terminals can be executed by a small number of test terminals without depending on network protocols.

A hot-water supply system 200 includes: a first tank 5 for storing hot water for heating; a second tank 6 for storing hot water to be supplied to a hot-water tap 3; a heater circulation path 51 for supplying the hot water of the first tank 5 to a heater 4; a first path 53 that includes a first heat transfer portion 10a surrounding the exposed portion of the second tank to the inside of the first tank 5 and that connects the first tank 5 to a forward portion of the heater circulation path 51 so that the hot water of the first tank 5 can be supplied to the heater 4 through the first heat transfer portion 10a; and a second path 55 that includes a second heat transfer portion 11a disposed along the first heat transfer portion 10a, and that allows heat exchange between the hot water of the second tank 6 and the hot water flowing through the first heat transfer portion 10a due to the flow, in the second heat transfer portion 11a, of the hot water of the second tank 6.
摘要:
A terminal apparatus is capable of efficiently managing the status of shared device(s) on the network in a unified manner, constantly, with the latest status information, thereby permitting a user easily to understand the status of the desired shared device. For each of the terminal apparatuses on the network, there are provided server and client. These function in the same manner regardless of whether the information exchange is with another apparatus or within one apparatus. The server means acquires and provides the information of the shared device, required from the client of another apparatus or the same apparatus.

A chemical heat-storage apparatus 100 is provided with: a container 202 accommodating a heat storage material 210 that has a higher specific gravity than water and exothermically reacts with water; a heat exchanger 209 that is provided inside the container 202 and that gives heat to the heat storage material 210 in a heat storage process as well as absorbing heat from the heat storage material 210 in a heat release process; a water flow path 204 that has openings 203 opening downwardly and that is provided below the heat exchanger 209 inside the container 202 so as to supply, to the inside of the container 202, the water to react with the heat storage material 210; and a distribution plate 206 that is provided below the heat exchanger 209 inside the container 202 and above the opening 203 and that has a plurality of through holes 205 for introducing the water supplied to the inside of the container 202 from a lower part to an upper part.
摘要:
It is an object of this invention to allow a user to perform operations while he or she is unconscious of the types of interfaces of various image input devices on a network. An image input server device on a network is searched for, device control information of an image input device locally connected to the found image input server is obtained from the server, and virtual device information based on a universal image in-out interface is generated from the obtained device control information. An image reading session is executed in collaboration with the image input server device by using the virtual device information and information of communication with the image input server device. An image input server device to which an image input device is locally connected receives a session request from a client on a network and determines the type of requesting client from the session request. Different image reading sessions are executed when the determination result indicates that the requesting client is a dedicated client and that the requesting client is a universal client.
