摘要:
In a hybrid integrated circuit device of the present invention, leads are fixedly attached on the upper surface of a circuit board. The lead includes an island portion, a slope portion, and a lead portion. A transistor and a diode are mounted on the upper surface of the island portion. Electrodes provided on the upper surfaces of the transistor and the diode are connected to a bonding portion through a fine metal wire. The bonding portion of the lead is disposed at a higher position than the island portion. Thus, the fine metal wires connected to the bonding portion are separated from each other.

A communication device includes a receiving unit configured to receive a frame via a connected packet network, a transmitting unit configured to transmit the received frame and a self-originating frame to the packet network, a monitoring unit configured to monitor a flow rate of the transmitted frames, a transmission cycle setting unit configured to cause a transmission cycle of the self-originating OAM frame to be a predetermined transmission cycle set for a normal condition when the flow rate of the frames is greater than or equal to a predetermined threshold, and a transmission cycle calculating unit configured to calculate a transmission cycle of the OAM frame that can compensate for a shortfall in the number of the transmitted frames, the transmission cycle calculating unit being configured to cause the calculated transmission cycle to be a transmission cycle of the self-originating OAM frame when the flow rate of the frames is less than the predetermined threshold.

A transmission source node transmits diagnostic frames where a TTL value is set to the number of hops that is counted until an intermediate node. A relay node decrements the TTL value of the received diagnostic frames, counts the number of diagnostic frames where the decremented TTL value is 0, and recognizes continuity between the transmission source node and the relay node based on the number of transmitted diagnostic frames transmitted from the transmission source node and the number of diagnostic frames where the decremented TTL value is 0.

A communication apparatus comprises: a memory unit which correlates a label assigned to a packet and an address of a source of the packet, and memorizes them as an entry; a receiving unit which receives a packet from a network; a learning unit which judges whether or not there exists an entry corresponding to the received packet in the memory unit, and in case there exists no entry corresponding to the received packet in the memory unit, stores a label assigned to the received packet and an address of a source of the received packet in the memory unit; and a processing unit which, in case there exists an entry corresponding to the received packet in the memory unit, assigns an address corresponding to the received packet to the received packet.
摘要:
Between a first pair of termination nodes, a first current-use packet transmission path and at least one first spare packet transmission path are defined. Between a second pair of termination nodes, a second current-use packet transmission path and at least one second spare packet transmission path are defined. When no network fault occurs, packets are transmitted between the pairs of nodes in a 1:1 transfer mode in which the pairs transfer packets via both current-use packet transmission paths only. When a network fault occurs in the first current-use packet transmission path, both transmissions are switched from a 1:1 transfer mode to a 1+1 transfer mode, in which the first pair of nodes transfer packets by using the first current-use packet transmission path and the first spare packet transmission path, and the second pair transfer packets by using the second current-use packet transmission path and the second spare packet transmission path.

摘要:
A packet transmission system includes a plurality of nodes connected by a packet transmission path. A current-use packet transmission path is used as the packet transmission path when a fault does not occur, and a spare packet transmission path is used as the packet transmission path when the fault has occurred. Each of the plurality of nodes includes: a transfer mode switching section configured to switch a transfer mode when transferring a received packet to a destination node to a 1:1 transfer mode or a 1+1 transfer mode, wherein the packet is transferred by the current-use packet transmission path in the 1:1 transfer mode, but the spare packet transmission path is not used, and the packet is transferred by the current-use packet transmission path and the spare packet transmission path in the 1+1 transfer mode; a path controller configured to instruct the transfer mode switching section to switch the transfer mode; a packet transferring section configured to transfer the received packet in the 1:1 transfer mode when the fault does not occur in the packet transmission network; and a reception path selecting section configured to select one of the packets received from the current-use packet transmission path and the spare packet transmission path in the 1+1 transfer mode.
摘要:
This communication system is equipped with a plurality of transceiver devices each composed of a transmission device that transmits unit data and a reception device that receives unit data from the transmission device. The transmission devices are connected in series. Each of the transmission devices stores identification information for identifying the device itself. The transmission device accepts unit data from a front stage side. The transmission device generates identification information for identifying one of the transmission devices from information included in the accepted unit data, in accordance with a predetermined generation process. In a case that the generated identification information corresponds to the stored identification information, the transmission device transmits the accepted unit data to the reception device. In a case that the generated identification information does not correspond to the stored identification information, the transmission device sends the accepted unit data to a back stage side.

A projection image display device including a display plane for displaying an image, a projection mechanism projecting an image on the display plane, and an imaging mechanism arranged on the same side of the display plane as the projection mechanism for imaging the display plane. The imaging mechanism is arranged at a position where a position symmetric with respect to the display plane of the projection mechanism is out of the range of the field angle of the imaging mechanism. By arranging the imaging mechanism at a position where no direct reflecting light of the light source of the projection mechanism comes, it is possible to prevent generation of a hot spot.
