摘要:
A first demultiplexer and a second demultiplexer receive and demultiplex STM-64 data to generate parallel data. A FEC frame generating encoder carries out error correction encoding operation in a column direction of the parallel data that constitutes a matrix, adds a resulting error correcting code to the parallel data, carries out error correction encoding operation in a row direction of the parallel data, and further adds a resulting error-correcting code to the parallel data. A first multiplexer and a second multiplexer multiplex the error-correction-encoded parallel data, and output the data as a FEC frame.

A parallel precoder circuit executes a differential encoding operation on an n-row parallel input information series, and outputs an n-row parallel output information series, where 2≦n. Output sets of differential encoding operation circuits each of which having a largest column number from among differential encoding operation circuits disposed in first row to (n−1)th row become first-row to (n−1)th-row parallel outputs information series, and an output set of an nth-row delay circuit becomes nth-row parallel output information series.

摘要:
This invention provides a package-type oil-cooled air compressor in which the housing is divided into two chambers, in one of which, a first chamber, are located the compressor unit, motor used to drive the compressor unit, air intake filter and intake regulator valve connected to the compressor unit, and in the other of which, a second chamber, are located the oil cooler and sirocco fan. An air duct connects the two chambers. Air outlets are formed in each of the chambers and an air inlet is formed in the second chamber. Air is introduced through the rotation of the sirocco fan into the second chamber via the air inlet. A portion of this air is directed into the first chamber via the air duct where a part is used to supply the compressor unit and the remainder flows over the components located in the first chamber to cool them and leaves via the outlet formed in the first chamber. The air that is not directed into the first chamber via the duct leaves the outlet formed in the second chamber after flowing over the oil cooler.
摘要:
A first frame counter generates a position signal for an input subframe address which is synchronized with an input clock signal based on an input frame phase signal. The first frame counter also generates a write address enabling signal. A subframe type detector generates a write/read control signal based on an input frame signal. Depending upon the position signal for the input subframe address, the write address enabling signal and the write/read control signal, a first subframe phase synchronization device and a second to nth subframe phase synchronization device control a buffer corresponding to 1/m of a frame data amount by a write address, where m (n>=m) is a multiplexing number. The first subframe phase synchronization device and the second to mth subframe phase synchronization device writes data corresponding to a first to mth input subframe signal based on the input frame signal into a buffer respectively. An input relative phase is synchronized with a standard relative phase. The synchronized signal is output as a synchronized frame signal.
