摘要： Radio devices (31 to 43) receive a prescribed number of Hello packets from each of n radio devices existing within one hop from each radio device, detects six pairs of maximum and minimum values MAX[1] and MIN[1] to MAX[6] and MIN[6] based on the plurality of reception signal strengths of the plurality of received Hello packets, detects two adjacent maximum values having the largest difference among six pairs of maximum and minimum values D_MAX[1] and D_MIN[1] to D_MAX[6] and D_MIN[6] when the six maximum values MAX[1] to MAX[6] are in descending order, and determines the average of two minimum values corresponding to the detected two maximum values as a threshold. The radio devices (31 to 43) each produce a routing table including routes having reception signal strengths equal to or more than the threshold.

摘要： The route maintenance unit outputs a period setting request to the period setting unit when the communication unit normally receives a Hello packet for the first time. The period setting unit sets a link connection confirmation period in response to the period setting request and outputs the set period to the route maintenance unit. The route maintenance unit maintains a radio link between the radio device in which the route maintenance unit is provided and an adjacent device upon receiving a data packet other than a Hello packet from the adjacent radio device even if a Hello packet is not received in the link connection confirmation period. Consequently, route disconnection or switching occurs less often.

摘要翻译： 当通信单元首次正常接收到Hello分组时，路由维护单元向周期设置单元输出周期设置请求。 周期设定单元响应于周期设置请求设置链路连接确认周期，并将设置的周期输出到路线维护单元。 路由维护单元在从邻接无线设备接收到除了Hello报文以外的数据分组的情况下，即使没有在链路中接收到Hello分组，也保持在提供路由维护单元的无线设备与相邻设备之间的无线链路 连接确认期。 因此，路由断开或切换较少发生。

摘要： The ignition timing is sustained at an initial value during a predetermined time beginning at a start of an engine, and is retarded after the predetermined time is elapsed to heat a catalyst at an early time. The predetermined time ends when the negative pressure of an intake pipe or the negative pressure of a brake booster reaches to a predetermined value. That is, the predetermined time is a period, which begins at a start of the engine and ends when a proper negative pressure can be sustained in the brake booster. As a result, it is possible to assure a negative pressure in the brake booster at an early time and to reduce exhaust emission at a start of the engine simultaneously.

摘要： A CDMA system includes first and second correlators, a delay buffer, a transmission-line correcting section, and a transmission-line estimating section. The delay buffer is supplied with the data for each symbol extracted from the first correlator to adjust a difference in timing at which the data is output from the first correlator, the difference being caused by a difference in spreading coefficient. The transmission-line correcting section is supplied with an output signal of the delay buffer. The estimating section is supplied with the data for each symbol extracted from the second correlator to obtain a transmission-line response from pilot information and supply transmission-line estimated value information to the transmission-line correcting section using the transmission-line response as an estimated value. The transmission-line correcting section makes a transmission-line correction to the information of the information channel based on the transmission-line estimated value information obtained by the transmission-line estimating section.

摘要： This invention aims at providing a catalyst body exhibiting a lower degradation of a catalyst due to thermal durability and capable of keeping higher catalyst performance for a long time. A catalyst component such as Pt is directly supported by Zr, W, etc, replacing elements inside a support such as Al of cordierite to provide a catalyst body without forming a coating layer. A combination of the catalyst component and the element inside the support is selected so that support strength is greater than 5 eV by simulation using a density functional method. Coarsening of catalyst particles can be suppressed and a high-performance catalyst body excellent in thermal durability can be obtained.

摘要： An endoscope shape detection system has a CPU included in a control unit. The CPU performs frequency sampling on digital data to calculate coordinates indicating the spatial positions of source coils incorporated in an insertion unit of an endoscope and of marker coils. An inserted state of the insertion unit of the endoscope is estimated based on the calculated coordinate data indicating the positions of the source coils. Display data based on which shape of the endoscope depicted is produced from the calculated coordinate data indicating the positions of the source coils, and output to a video RAM. Display data based on which marker coils are depicted is produced from the calculated coordinate data indicating the positions of the marker coils, and output to the video RAM. Consequently, the positions of the markers are depicted together with the shape of the endoscope. The positional relationship between the insertion unit of the endoscope and a patient's body can therefore be ascertained.

摘要： In a fuel injection control system for an internal combustion engine, a fuel atomization device is provided to atomize fuel injected at the time of engine starting. The fuel atomization device may be a type which increases fuel pressure to a higher value at the time of engine starting than after the engine starting. Alternatively, the fuel atomization device may be a type which supplies assist air to the injected fuel. An intake valve is opened for a longer period at the time of engine starting than after the engine starting, so that more fuel may be supplied to an engine cylinder. A fuel leakage which may occur during engine stop is estimated, and the amount of fuel to be injected at the time of next engine starting after the engine stop is corrected by the estimated amount of fuel leakage. Fuel injection timing at the time of engine starting is retarded relative to that of post-engine starting. The amount of injected fuel adhered to an intake port and not supplied into an engine cylinder after the closing of the intake valve is estimated, and the amount of fuel to be injected next is corrected thereby.
