摘要:
At a CRC transmission side of a cross connect equipment, a CRC operation is applied to received channel data of each channel independently and sequentially in every sub frame having the same number of channels, series of which sub frames set up a main frame. The resultant CRC code of each channel obtained in a preceding sub frame is coupled to the received channel data of the corresponding channel to apply the same CRC operation to the thus received channel data, thereby the accumulated result of each channel is added in the last sub frame. At a CRC reception side, a cyclic CRC operation similar to that achieved at the CRC transmission side is applied to an outgoing channel data provided with the resultant CRC codes for each channel to obtain CRC results. During the cyclic CRC operation, a CRC error that once occurs is held during the main frame.

A time switch control system having a cross-connect function is used for digital time-division. Multiplex communications permit desired channel settings and reduce power consumption. Identifying circuits identify which time-slot signals are to be retained by an input signal retaining memory, and output identification information to the retention memory, and to a retention memory controller. The retention memory controller stores therein the identification information from the identifying circuits, then reads out the identification information, and controls the input signal retaining memory in accordance with the contents of the identification information. Only the specified time-slot signals are stored and retained by the input signal retaining memory, thereby reducing power requirements. Exchange/output circuits exchange the time-slot signals stored in the input signal retaining memory in accordance with channel setting information, and output the exchanged signals.

A digital signal transmission system includes a synchronization pattern detection circuit for detecting a synchronization pattern in response to a received transmitted digital signal, a pseudo synchronization detection circuit for detecting a pseudo synchronization pattern in the form of cyclic redundancy code in response to a received transmitted digital signal, and a synchronization protection circuit for counting the synchronization pattern detection signals produced when synchronization patterns are detected in response to a synchronization pattern detection signal from the synchronization pattern detection circuit. The synchronization protection circuit includes a main synchronization counter circuit and an auxiliary synchronization counter circuit. The count of protection steps for the confirmation of synchronization recovery of the auxiliary synchronization counter circuit in accordance with synchronization or asynchronization of the main synchronization counter circuit is variable.

A coating machine enables the inside of a paint chamber to be washed clean with less amount of use of thinner by increasing washing efficiency and is capable of forming a coating with uniform coating thickness by always uniformly jetting a paint over 360° about a rotary atomizing head and the rotary atomizing head of the coating machine. The coating machine includes the rotary atomizing head in which the paint chamber is formed in the clearance between an outer bell fitted to the tip of a tubular rotating shaft and an inner bell fitted to the front side of the outer bell. Fins agitating, in the paint chamber, a washing fluid supplied from a thin tubular nozzle inserted into the tubular rotating shaft are radially formed on the rear surface side of the inner bell. An annular paint groove temporarily accumulating the paint is formed in the inner surface of the rim part of the outer bell on which the paint jetted from the paint jetting holes formed at the peripheral surface part of the paint chamber is extended.
