摘要： In a network system wherein a plurality of terminal devices communicates with each other via respective node devices over a ring transmission line, a transmitting node device can confirm whether a multicast information transmission has succeeded or failed. The transmitting node device send a response frame after a multicast information frame. A receiving node device relays the multicast information frame and a response frame from the upstream node device to the downstream one when the multicast information has been received successfully, or in case of a failure in receiving the multicast information, sends a response frame to the downstream node device by changing at least part of the response frame from the upstream node device. The transmitting node device can determine from a received response frame if there is one or more of the receiving node devices which cannot receive the multicast information.

摘要： Frontend LANs connecting plural stations are connected to plural nodes of a backbone LAN respectively. The backbone LAN is constituted by plural physical or logical links, and each node corresponds to each frontend LAN. A first data block is segmented into one or plural second data block units of fixed length and transferred to destination nodes, a bridge is provided in order to assemble the second data blocks into the first data block. The bridge can transmit the second data blocks to arbitrary links, and the receiving is performed through one link. The bridge a decoder also has a decoder for decoding whether the learning should be performed or not, based on the learning indication information existing in the second data block including the routing information.

摘要： In a network having a plurality of node apparatus connected to a transmission line, each node apparatus segmenting a transmission message into information blocks of a predetermined length and transmitting them to the transmission line in the form of a fixed length packet (cell) having a source address, each node apparatus sequentially stores packets having different source addresses in vacant memory blocks of a buffer memory. There is written in each memory block the packet data as well as a next address pointer indicating a memory block in which the next received packet having the same source address is stored. When a packet containing the last information block of a message is received, stored in a read address queue is the address indicating the memory block which stores the first information block of the same packet. Reading the first block of a message from the buffer memory is executed in accordance with an address read from the read address queue, and reading the following blocks is executed in accordance with the next address pointer. Read/write of the buffer memory is alternately executed in units of memory block.

摘要： A decoding circuit is operative to decode a differential Manchester code consisting of four symbols "J", "K", "1" and "0" each composed of two consecutive signal elements. For detection of the symbol "J" and consequent determination of the symbol boundary, the decoding circuit has a circuit configuration which takes advantage of the fact that the symbol "K" immediately follows the symbol "J" and three consecutive signal elements, two of which are included in the symbol "J" and one of which is for a symbol immediately preceding the symbol "J", have the same polarity. To prevent an error that a second occurrence of the symbol "J" is detected after completion of detection of the symbol "J", the decoding circuit has an additional circuit configuration which inhibits the detection of the symbol "J" until the symbol "0" or the symbol "1", for example, is detected.

摘要： An engine powered machine is provided with a high-performance exhaust gas purification system and is capable of promptly raising a temperature of an operator's cab to a comfortable temperature. The exhaust gas purification system that makes use of an NOx removal catalyst and a reducing agent is provided with a reducing agent heater for heating a reducing agent, which is stored in a reducing agent tank, with heat of an engine cooling medium and an on/off device for controlling an introduction of the engine cooling medium into the reducing agent heater. When a temperature of the engine cooling medium is higher than a first predetermined temperature, a temperature of the reducing agent in the tank is lower than a second predetermined temperature and a temperature in an operator's cab is lower than a third predetermined temperature, a controller switches the on/off device into a closed state to increase a flow rate of the engine cooling medium to be guided to a heat exchanger of a heating apparatus.

摘要： A priority valve 7 is disposed between a hydraulic pump 2 and a steering valve 4 and is used to supply priority steering cylinders 103a and 103b with pressurized oil discharged from the hydraulic pump 2 by controlling the differential pressure across a meter-in hydraulic line of the steering valve 4 such that the differential pressure is kept at a target value. A pressure sensor 31 for detecting the load pressures of the steering cylinders 103a and 103b is provided. On the basis of the detected load pressures, the target value set for the priority valve 7 is modified by devices including a controller 32, a solenoid valve 33, a pilot hydraulic line 29, and a pressure receiving unit 24c of the priority valve 7. The above configuration enables suppression of a shock occurring at the start of turning of the steering wheel.
