A source terminal measures characteristics of the path at the source terminal itself, produces a characteristics-measurement packet, and transmits the produced characteristics-measurement packet to a relay terminal. Upon receiving the characteristics-measurement packet, the relay terminal measures characteristics of the path at the relay terminal itself, renews the characteristics of the path included in the characteristics-measurement packet using the measured characteristics of the path, and transmits the characteristics of the wireless communication path to the destination terminal. The source terminal produces an admission-request packet and transmits the packet to the destination terminal. Upon receiving the admission-request packet, the destination terminal allows or rejects the traffic quality maintenance request according to the characteristics of the wireless communication path. The allowance or rejection of the quality maintenance request is transmitted to the source terminal with the admission-reply packet by the destination terminal.
摘要:
In a radio communication system, a relay route is established with a plurality of wireless devices constructing an MPR set for a wireless device as a root node by transmission and reception of a Hello packet. A wireless device other than that constructing the MPR set transmits neighboring wireless device information, information of a neighboring wireless device thereof, to the wireless device as the root node via the relay route. Based on the neighboring wireless device information received via the relay route, the wireless device as the root node generates and stores topology information indicating a topology of a plurality of wireless devices constructing the radio communication system. The wireless device as the root node transmits the topology information to a plurality of wireless devices on a regular basis, or transmits to a wireless device requiring the topology information. As a result, radio communication can be performed with reduced overhead.

This invention involves a fiberglass composition containing the following components: SiO2, Al2O3, CaO, MgO, B2O3, F2, TiO2, K2O, Na2O, Fe2O3 and SO3. The weight percentage of each of the components are as follows: SiO2 58˜65%, CaO 20˜26%, Al2O3 9˜17%, MgO 0.5˜1%, B2O3 0˜5%, F2 0˜1%, TiO2 0.1˜1%, K2O+Na2O 0˜0.8%, Fe2O3 0.1˜0.5%, SO3 0˜0.6%. The ternary system, SiO2—Al2O3—CaO, is basis of the fiberglass composition in this invention, which also has low quantities of MgO and B2O3. In addition, the total amount of alkaline earth oxide and the proportional relationship between MgO and CaO are rationally designed, which helps to improve the mechanical strength, heat resistance, and chemical stability of the glass. It also has excellent manufacturing performance. Moreover, the raw materials of the fiberglass composition in this invention are low in cost, and the invention meets environmental protection requirements.

A radio device, which is the source, transmits a route request packet (RREQ) to a radio device. In response to the route request packet (RREQ), the radio device transmits to the radio device a route setup packet (RSET) including a route Radio Device Radio Device Radio Device Radio Device by looking-up topology information (TPIF). In response to the route setup packet (RSET), the radio device produces a route notification packet (RNTF) and transmits the produced route notification packet (RNTF) to radio devices, and. In response to the route notification packet (RNTF), the radio device, which is the destination, produces a route reply packet (RREP) and transmits the produced route reply packet (RREP) to the radio device, which is the source.

An electrolysis device, for producing alkaline water from water, includes an electrolysis vessel, a pair of high porous electrodes arranged in the electrolysis vessel, and a cell unit arranged between the positive and negative electrodes. The pair of high porous electrodes respectively serve as a positive electrode and a negative electrode. The cell unit includes a bipolar membrane element and at least one cation exchangeable membrane. The bipolar membrane element has a cation exchangeable side and an anion exchangeable side. The cation exchangeable side is closer to the negative electrode than the anion exchangeable side. The cation exchangeable membrane is arranged between the anion exchangeable side of the bipolar membrane element and the positive electrode, so as to define an alkalic chamber between the bipolar membrane element and the cation exchangeable membrane.
