Abstract: A local area network system in which a logical ring is formed by at least part of said node stations to pass a token frame from one station to another in an endless and cyclic fashion allowing each of said node stations which has received is allowed to transmit data, and said data comprises event data. Since only the stations holding the token are allowed to transmit cyclic data and event data, each station is not required to be equipped with a monitoring timer so that not only the LAN can be constructed economically but also transmission efficiency can be improved through speed up in determining the completion of data transmission.

Abstract: A system of conveyors and handlers for manufacturing copper clad laminates is disclosed. The system has a layup station including at least two clean rooms in which B-stage and copper foil sheets are respectively placed. A sandwich comprising a copper foil sheet placed into contact with a press plate is conveyed from the first to the second clean room where a B-stage sheet is positioned against the copper foil. The resulting uncured laminate is then transferred with its press plate to a stacking station until a predetermined number of laminates, separated by press plates, is stacked into a "book". One or more books are then conveyed through press loading equipment where heat and pressure are applied to cure the laminates. The books are then transferred to a breakdown station where the cured laminates and press plates are successively and sequentially stripped from the book. The press plates are conveyed back to the layup station for recycling into "new" books with each press plate cleaned immediately prior to reentering the first clean room. To minimize the migration of B-stage dust or fibers from the second to the first clean room, the ambient atmospheric air pressure within the first clean room is maintained at a greater pressure than the air pressure within the second clean room.

Abstract: A fast packet switch comprises one buffer (200) directly connected between a plurality of input ports and a plurality of output ports to effect rapid throughput of data packets. A pointer to a location in the buffer is allocated by a buffer manager (206) upon receipt of notification of an incoming packet at the receiving input port and the input port delivers the packet as it is received to the location designated by the pointer. After the data packet is received, the input port delivers the pointer and a destination address for the packet to a router (208), which selects one of the plurality of output ports based on the destination address. The router queues the pointer in a queue for the selected output port. The output port then retrieves the data packet from the buffer using the pointer to determine the location, and transmits the data packet. After the transmission is complete, the output port returns the pointer to the buffer manager. This packet switch may be pipelined to receive, route, and transmit simultaneously on adjacent data packets. <IMAGE>
