摘要： PURPOSE:To obtain a counting device without executing the erroneous counting to the mixing of foreign matters by using a color classified sensor. CONSTITUTION:A detecting part main body 1 is provided with a pipe 5, and is shaped of a perforated plate, and a cleaning body 6 and mixed foreign matters 7 pass through an aperture part together with a water flow. A color classified sensor 2 is arranged vertically to the aperture part of the detecting part main body 1, the cleaning body 6 to pass through the aperture part is detected by the color and the detected signal is sent to an arithmetic part 3. The body is transferred from the arithmetic part 3 to a displaying part 4 and the number of the passing of the cleaning bodies is displayed. Thus, only the cleaning body can be detected and counted, and therefore, the counting error can be eliminated.

摘要： PROBLEM TO BE SOLVED: To shorten time during which communication becomes impossible caused by a change in a communication path due to a maintenance work and occurrence of a fault in a line emulation device having redundant configuration of the communication path. SOLUTION: Upon switching of physical ports used for the communication, a frame for updating an MAC (Media Access Control) address learning table for informing another connected device of a change in MAC address of itself is issued. The device which receives the frame for updating updates the learning table based on information on a transmission source MAC address in the frame, does not handle the frame for updating as a user frame, and immediately cancels the frame.

摘要： PURPOSE:To obtain the title apparatus having a simple structure, reduced in pressure loss and capable of certainly removing foreign matter, by automatically operating a drift generating valve, a filter member and a foreign matter withdrawal valve arranged in specific positional relations to remove the foreign matter. CONSTITUTION:In this foreign matter removing apparatus 11, filter members 4 are provided around a partition plate 8 in a body 3 and a drift generating valve 5 is provided on the upstream side or lateral side of the partition plate 8, and foreign matter withdrawal pipe 6 and a foreign matter withdrawal valve 7 are provided on the downstream side of said partition plate 8. When foreign matter is adhered to the filter members 4 and differential pressure rises, the drift generating valve 5 is rotated so as to become parallel to the filter members 4 and parallel flow is generated to allow the foreign matter 10 adhered to the filter members 4 to move to the downstream side and, by opening the foreign matter withdrawal valve 7, said foreign matter is discharged out of the system through the foreign matter withdrawal pipe 6 provided on the downstream side. As a result, the apparatus having a simple structure, reduced in pressure loss and capable of certainly removing the foreign matter mixed with the cooling water used in a tubular heat exchanger can be obtained.

摘要： PROBLEM TO BE SOLVED: To realize a protection for an ATM(asynchronous transfer mode) areas simultaneously at a high speed. SOLUTION: An active VC (virtual connection) 10a and a standby VC 10b are provided between ATM communication equipments 1-1, 1-2, and a block between a line card 3-1 of the ATM communication equipment 1-1 and a line card 3-3 of the ATM communication equipment 1-2 is used for an OAM (operation and maintenance) monitor block and protection block. On the occurrence of a fault 16 in the VC 10a, the ATM communication equipment 1-2 uses an interface 6-3 to generate a protection request cell and sends it to the ATM communication equipment 1-1, which receives the cell by an interface 6-1 and replaces the active VC 10a with the standby VC 10b and sends a protection notice cell to the ATM communication equipment 1-2. The interface 5-3 replaces the active VC 10a with the standby VC 10b. Thus, the communication by the VC 10b is attained not via a control section 4.

摘要： PROBLEM TO BE SOLVED: To effectively utilize memory capacity of a routing table (cache memory) provided with each channel interface of a communication node device and to improve the retrieval hit rate of routing information. SOLUTION: Channel interfaces 1-1 to 1-n of a communication node device detect a connection interrupt flag included in a received packet to eliminate an unnecessary routing information entry from a sub routing table. In the case of downloading the routing information entry from a main routing table 55 because no object entry is in existence in the sub routing table at reception of a packet, when a connection setup flag is set to the received packet, the packet is registered as an entry with high priority entry.

摘要： PROBLEM TO BE SOLVED: To quickly execute congestion control by generating promptly an RM cell added with congestion information in a communication equipment in which congestion occurs, and transmitting it to a communication terminal or the communication equipment transmitting a cell to be the factor of cell buffer congestion. SOLUTION: When the quantity of inter-device cells accumulated in cell buffers 2a, 2b exceeds a threshold, the congestion is judged to have occurred, and a cell buffer detecting part 3 detects the identifier of the cell buffer in which the congestion occurred, and reports it to line dealing with parts 100a, 100b. Cell buffer identifier-to- received cell header information retrieving parts 5a, 5b generate newly a congestion reporting RM cell having the same VPI and VCI as the VPI snf VCI of the detected identifier in the header. Selector parts 7a, 7b receive the control of the information retrieving parts 5a, 5b, and insert the congestion reporting RM cell into the transmission cell, and output it to interfaces 300a, 300b, and transmit it directly to a cell transmitting origin making the congestion. Thus, response time till the communication terminal or the communication equipment transmitting the congestion factor cell slows down transmission cell speed is shortened.
