A lubricating oil for a compression-type refrigerator using a hydrofluorocarbon refrigerant including a polyvinyl ether-based compound containing in the molecule an alkylene glycol unit or a polyoxyalkylene glycol unit and a polyvinyl ether unit and having a molecular weight in the range of 300 to 3,000, and a refrigeration apparatus using the lubricating oil. A cylindrical skin positioned about the cylindrical rib and mounting structure allows the structure to slide in and out of the skin. A propeller-like member associated with the tail portion and secured by a tube-like element causes the lure to spin when it is retrieved. The MIF code file is formatted so that it is compatible with the pagination program, and the resulting file is flowed directly to the pagination program.
