A waveguide converter includes a waveguide including a hollow section through which a signal is transmitted and a first opening formed on a cross section of the hollow section in a direction orthogonal to a transmission direction of the signal, and a circuit board including on a same surface a signal line, a conductor patch connected to the signal line, and a second opening surrounding the conductor patch. The waveguide is fixed onto the circuit board. The first opening surrounds the second opening. The conductor patch includes a rectangular section which has short sides in parallel with short sides of the first opening, and has a first long side and a second long side connected to the signal line in parallel with long sides of the first opening, and protruding portions which are provided so as to touch the short sides near both ends of the second long side, respectively.

When a problem occurs in a computer system, the following processing is performed. That is, a troubleshooting procedure that includes, at least, operation content and input request for system information, presented to an operator, and in which command to acquire system information related to the input request from the information source of the system information are assigned to the input request, is referenced. Furthermore, in accordance with the command, system information is collected from an information source where system information exists. Then, after those input request for system information have been removed from the troubleshooting procedure, the resultant troubleshooting procedure is presented to the operator. Thus, the workload of the operator in the troubleshooting operation can be significantly reduced, and the time until the operation is completed is shortened, making rapid troubleshooting possible.

A recording medium stores a program which causes a computer to execute a process for responding to failure of a management subject apparatus, based on incident information. The program causes the computer to execute a management procedure. The procedure manages steps of the response to the failure with the incident information. A response knowledge acquisition procedure referring to failure response information in which is described response knowledge corresponding to each step of the response to the failure, and acquires response knowledge for the failure in accordance with the step of the response to the failure managed by the failure response step management procedure with the incident information. A response knowledge process execution procedure executes a process in accordance with the response knowledge for the failure acquired by the response knowledge acquisition procedure.

The communication availability information between a plurality of transmitters and a plurality of destinations before the communication state between a transmitter and a destinations in a communication network changes from available to unavailable is compared, layer by layer from an upper layer toward a lower layer, with the communication availability information after change, and destinations in paths where the communication state has changed from available to unavailable are grouped. Thus, the communication network is divided into a plurality of affected ranges and an interface of a device located at the border between the affected ranges is deduced as a fault occurrence point.

According to this invention, it is possible to display the overall configuration of a network and, at the same time, an important part of the network in detail according to the objective of monitoring so as to be able to grasp/monitor the important part of the network in detail, while globally grasping/monitoring the network configuration, for the purpose of an efficient monitoring operation on the network configuration. A network configuration management apparatusfor managing the configuration of a networkformed by connecting a plurality of network devices comprises a topology information acquiring sectionfor acquiring topology information on each of the network devices and a degree of importance determining sectionfor computationally determining the degree of importance of each of the network devices, using the topology information acquired by the topology information acquiring section. The apparatusdisplays a network map on the basis of the computationally determined degrees of importance.

An amplifier apparatus including a first dividing circuit disposed at the input side of an amplifier, for dividing an input signal into a primary signal to be amplified by the amplifier and an auxiliary signal for distortion detection, a distortion compensating signal generating circuit for generating a distortion compensating signal, based on the auxiliary signal and the output of the amplifier, to compensate a distortion component contained in the output of the primary amplifier and inputting the generated signal into the amplifier, and a primary signal combining circuit for combining the primary signal obtained by the first dividing circuit 1 with the distortion compensating signal. The result is that even using an auxiliary amplifier whose gain is small or without using such auxiliary amplifier in a feedback system, the distortion component contained in the output of the amplifier can be effectively compensated.
