摘要:
A wireless base station which controls joining of a plurality of wireless terminals to a wireless network, stores a maximum joining possible terminal number which indicates a maximum number of the wireless terminals of each terminal type that can join the wireless network simultaneously, and which is set in advance for each one of a plurality of terminal types that classify the wireless terminals, and a currently joining terminal number which indicates a number of the wireless terminals of each terminal type that are currently joining the wireless network, for each one of the plurality of the terminal types. Then, the wireless base station judges whether the joining of one wireless terminal of one terminal type which sent a request message to the wireless network is permitted or not, according to the maximum joining possible terminal number for the one terminal type and the currently joining terminal number stored for the one terminal type.

A capacitor device comprises a capacitor element and an interposer. The capacitor element has a connection surface and comprises an anode electrode and a cathode electrode. The anode electrode and the cathode electrode are formed, at least in part, on the connection surface. The interposer comprises an insulator substrate, a plurality of first anode terminals, a plurality of first cathode terminals, a second anode terminal, a second cathode terminal, an anode through-hole and a cathode through-hole. The insulator substrate has first and second surfaces and has no inner conductive layer. The first anode terminals and the first cathode terminals are formed on the first surface. The first anode terminals are more in number than the anode electrode of the capacitor element. The first cathode terminals are more in number than the cathode electrode of the capacitor element The second anode terminal and the second cathode terminal are formed on the second surface. The second anode terminal is connected to the anode electrode. The second cathode terminal is connected to the cathode electrode. The anode through-hole and the cathode through-hole are formed in the insulator substrate. The anode through-hole connects between the first anode terminals and the second anode terminal. The cathode through-hole connects between the first cathode terminals and the second cathode terminal.

The frequency of reading, by users, Web sites managed by Web masters is increased. A server computer of a service provider providing a variety of services can be accessed from one of the Web sites of registered Webmasters. The server computer registers a client who has accessed it through one of the Web sites. Only when the registered client accesses the service provider through the Web site, the client can receive any one of the services.
摘要:
An outside DTCP bridge for relaying information between an outside communication device connected to an outside network and a home communication device connected to a home network, carries out a first authentication and key exchange processing for purpose of copyright protection between the outside DTCP bridge and the home communication device as well as a second authentication and key exchange processing for purpose of copyright protection between the outside DTCP bridge and the outside communication device, and stores an identification information of the outside communication device. Then, transmission/reception of information between the home network and the outside network is carried out only when the outside communication device which made the access request is stored and both the first authentication and key exchange processing and the second authentication and key exchange processing succeed.
