In a wireless telecommunication system, a power control apparatus performs a data telecommunication with a control target apparatus and receives data arrival acknowledgement information transmitted therefrom in a data retransmission layer. Then it judges a reception quality of the control target apparatus by using the received data arrival acknowledgement information and changes a target power quality which is set up for the control target apparatus based on a result of the judgment. And it notifies the control target apparatus of the changed target power quality.

A bipolar plate for a fuel cell comprises a substrate formed of stainless steel; an oriented amorphous carbon film formed at least on a surface of the substrate facing an electrode, and containing C as a main component, 3 to 20 at. % of N, and more than 0 at. % and not more than 20 at. % of H, and when the total amount of the C is taken as 100 at. %, the amount of C having an sp2 hybrid orbital (Csp2) being not less than 70 at. % and less than 100 at. %, and (002) planes of graphite being oriented along a thickness direction; a mixed layer generated in an interface between the substrate and the oriented amorphous carbon film and containing at least one kind of constituent atoms of each of the substrate and the oriented amorphous carbon film; and a plurality of projections protruding from the mixed layer into the oriented amorphous carbon film and having a mean length of 10 to 150 nm.
摘要:
A wireless communication system includes a multi service supplying unit which transmits the same data to a plurality of user equipment and a quality evaluation result collecting unit which collects quality evaluation results of a multi service from the plurality of user equipment. The wireless communication system includes a resource controlling unit which controls shared wireless communication resources used for the multi service according to the quality evaluation results.
摘要:
In a wireless base station, a specific information receiver receives specific information delivered from a higher-level device to a wireless terminal. A specific information deliverer delivers the specific information to the wireless terminal via multiple physical channels activated in a wireless base station. Where a common channel via which information is periodically broadcast to multiple wireless terminals and a shared channel of which available radio resources are allocated to wireless terminals to transmit voice data and the like to the terminals are activated in the wireless base station, for example, the specific information deliverer can deliver the specific information using the common channel if the wireless terminal is in a standby state, and can deliver the specific information using the shared channel if the wireless terminal is in a communicating state.
摘要:
A mobile communication system includes a plurality of radio base stations forming respective radio zones and a mobile station selecting a wait zone and a base station to which a request for a message channel is to be issued. Each of the plurality of radio base stations is assigned an order of priority. Information relating to the order of priority is used by the mobile station to select a wait zone and a base station to which a request for a message channel is to be issued.
摘要:
A method for producing a fuel cell separator which suppresses increase in an electrical conductivity of a coolant to reduce the contact resistance. A method for producing the fuel cell separator for separating gases between adjacent cells for the fuel cell which includes forming a separator substrate having projections and recesses from a metal material such as a titanium material or a stainless steal, and forming an electrical-conductive layer with an electrical conductor of gold or the like only on the projections of the separator substrate.
摘要:
