Abstract: A switch station including an ATM switch; a memory storing control data for operations of the switch station; an intra-station device, accommodating a subscriber line, performing communication operation on subscriber ATM cell; a control processor generating control information in link access protocol (LAP) format; and an interface unit converting LAP control information into ATM cell to the intra-station device through the ATM switch, wherein the control information is communicated according to LAP, the intra-station device receives the control information and transmits a direct memory access request to obtain control data stored in the memory, the interface unit obtains and converts the data format of the control data into ATM cell to transmit to the intra-station device through the switch, and the intra-station device performs the communication operation on the subscriber ATM cell based on the control data received through the switch.

Abstract: The quality and performance of the connectionless communications system are improved. When a BOM is received, the destination address DA of the L3-PDU stored in the payload of the BOM is retrieved, and the tag information is obtained from the DA (S11). The output message identifier MID is reserved (S12), and the tag information and output MID are assigned to the BOM (S13). Then, the tag information and output MID are written to the table. When a COM is received, the tag information and output MID are retrieved using the MID of the COM as a key, and the information is provided for the COM (S31 and S32). When an EOM is received, the tag information and output MID are retrieved using the MID of the EOM as a key, and the information is provided for the EOM (S41 and S42). Then, the output MID is released (S43).

Abstract: In a fixed-length cell handling-type exchange, a private line connection is set by automatically reserving a usable path and a necessary band at a designated time. The exchange includes a storage unit which has a connection reservation information storage unit which stores private line connection reservation information and control unit which includes a command reception unit for receiving a command having the private line connection reservation information. A reservation information management unit stores the private line connection reservation information received by the command reception unit into the connection reservation information storage unit of the storage unit. A time information confirming unit confirms the period of the private line connection by referring to the connection reservation information storage unit at constant time intervals.

Abstract: A method of treating steel sheets which have good corrosion resistance after forming, which comprises coating a steel sheet with a solution which contains:(a) water-soluble or water-dispersible lithium silicate at a concentration of 2 to 250 g/l, which lithium silicate is a mixture of silicic acid or silicate and lithium salt in a molar ratio of 20:1 to 1:1.(b) at least one water-soluble or water-dispersible saturated or unsaturated fatty acid compound, higher alcohol wax, polyethylene type resin, fluorine type resin or silicone type resin at a concentration of 1 to 250 g/l.

Abstract: A steel sheet is provided herein which has been treated to form thereon a first very thin layer of tin and a second layer of hydrated chromium oxide. This treated steel sheet can effectively be coated with an organic coating, and can be used for producing cans for foodstuffs and carbonated beverages.

Abstract: A steel sheet which has been treated to form thereon a first layer of an iron-tin alloy and a second layer of hydrated chromium oxide. This treated steel sheet can be effectively coated with an organic coating, and is useful in forming cans for foodstuffs and carbonated beverages.

Abstract: A method of providing a composite coated steel sheet is provided herein by dipping a steel sheet into a suspension solution consisting of a water-soluble and/or water-dispersible organic polymer resin, a water-dispersible sol of a metal compound and an infusible powder of a water-insoluble polymer resin, removing the coated steel sheet from the suspension and curing the coated composite by heat treatment. In certain cases, a metal powder, an alloy powder of said metal and a powder of a difficultly water-soluble or water-insoluble compound of said metal may be used in the suspension solution.
