摘要:
The present invention provides a refrigerating machine oil composition for use in a compressor for a refrigerator in which a sliding surface of at least a part of constitutional members of the compressor is coated with a lubrication film-forming composition containing a resin having a heat distortion temperature of 100° C. or higher as a binder, and a solid lubricant, wherein the refrigerating machine oil composition contains a base oil made of a polyoxyalkylene glycol having a kinematic viscosity of from 3 to 50 mm2/s as measured at 100° C., and a compound selected from the group consisting of amide compounds, amidated amino acid compounds and aliphatic amines having a specific structural formula which compound is contained in an amount of from 0.01 to 1% by mass on the basis of a total amount of the refrigerating machine oil composition, the refrigerating machine oil composition being capable of ensuring a good lubrication of sliding portions of the compressor upon starting operation of the compressor and during the operation; a compressor using the refrigerating machine oil composition; and a refrigerating apparatus including the compressor.

A scroll type compressor has a rotary shaft, a fixed scroll member, a movable scroll member and a rib. The fixed scroll member has a fixed end plate and a fixed scroll wall. The fixed end plate has first and second sides. The fixed scroll wall is formed on the first side. The movable scroll member has a movable end plate and a movable scroll wall. The movable scroll wall is formed on the movable end plate. The movable scroll member is adapted to make an orbital motion in accordance with the rotation of the rotary shaft whereby a compression chamber to decrease the volume of the compression chamber with the orbital motion of the movable scroll member is formed between the fixed scroll member and the movable scroll member. The rib is provided on the second side so as to extend behind the inner end of the fixed scroll wall.

An automatic ID assigning device for LAN instruments connected in a network assigns ID numbers from a master LAN instrument to respective slave LAN instruments connecting sequentially to the master LAN instrument. A first slave LAN instrument stores, as its own self ID, an ID number supplied in an ID assignment command signal supplied from the master LAN instruments through a data line connecting ports of respective slave LAN instruments. The slave LAN instrument returns an ID assignment acknowledging signal to the master LAN instrument and connects upper and lower ports of the slave LAN instrument together. The master LAN instrument updates a connecting number table of the ports of the slave IDs upon receipt of the assignment acknowledging signals and transmits a subsequent ID assigning command signal to another slave LAN instrument through the data line and through the connected ports of slave LAN instruments to which ID numbers have already been assigned. The upper and lower ports, i.e., the input and output administrative data lines, of the slave LAN instruments to which ID numbers have not yet been assigned are not connected to each other.
