摘要： An electrical discharge machine feeds an electrode wire received within a guide tube to a process region of a machined article. The electrical discharge machine includes a cylindrical hollow driving shaft arranged in a vertical direction, which has a space for receiving the guide tube with the electrode wire along a vertical central axis. A head assembly includes a first holding member for holding the guide tube, and a second holding member for holding the electrode wire extending from a bottom opening of the guide tube. The head assembly is detachably coupled with a bottom portion of the driving shaft. Therefore, the electrode wire can be replaced by replacing the head assembly.

摘要： A detected value indicating a machining state is filtered and a machining gap between an electrode and a workpiece is adjusted by using a control variable obtained through the filtering. Therefore, machining speed can be improved by maintaining a stable machining state through suppression of a disturbance in a gap distance control system due to eccentricity of an electrode, due to fluctuations in electric characteristics at feeding brush sections, and due to mechanical resonance of the electrode driving system.

摘要： In a parallel processor system comprising a plurality of processor elements constituting a network, a source processor element wishing to broadcast data to a plurality of destination processor elements sends a broadcast request message containing the target data to a broadcast exchanger. The broadcast exchanger converts the received message into a broadcast message and sends it over the network to the destinations. A plurality of broadcast request messages, if transmitted parallelly to the broadcast exchanger, are serialized thereby so that only one broadcast message will be transmitted at a time over the network. This prevents deadlock from occurring between different broadcast messages. The routes for transmitting broadcast request messages and those for transmitting broadcast messages are arranged so as not to overlap with one another. This suppresses deadlock between any broadcast request message and broadcast message. The broadcast exchanger is replaced alternatively with one of the partial networks. These schemes all apply where long messages are transmitted through worm-hole routing.

摘要： A computer system is composed of a processor 10, a memory control circuit 70, and interleaved bank memories 41 through 44. The memory control circuit contains random access queue entries 71 through 73 commonly used by all memories 41 through 44. A bypass 80 allows direct bank access without writing memory access requests to the queue entries 71 through 73. Sequence is maintained by the in-bank access sequence assurance circuits 90. Because the queue entries 71 through 73 allow memory control without providing the number of entries in an integral multiple of the number of banks, the entire circuit scale is reduced. All bank busy circuits in the system are integrated on a single LSI to reduce delay, thereby enhancing processing speed. The bypass 80 eliminates queue read/write cycles from data access time, thereby enhancing processing speed.
