Abstract: A compressor and a refrigerating machine which enable an easy disposal of a lubricant, are friendly to the natural environment, and have simple configurations, are provided. The compressor which is used in a refrigerating machine including an evaporator and a condenser and adapted for compressing refrigerant gas evaporated in the evaporator to convey the compressed refrigerant gas to the condenser, includes: a motor; a housing having a compression chamber inside; a rotary member which has a rotating shaft and is rotated by a driving force of the motor so as to compress water vapor serving as the refrigerant gas in the compression chamber; a bearing for supporting the rotating shaft of the rotary member in the housing; and a lubricant supplier for supplying water serving as a lubricant to the bearing.

Abstract: Heterogeneous surface with polar functional groups as nucleation points. These nucleation points cause precipitation of a substance, for example ice or salt, in a fluid at these nucleation points under suitable physical conditions because the Gibbs free energy of the system is lower at the nucleation points than between the nucleation points, where said system comprises said surface and said fluid with said substance near said surface.

Abstract: In the condenser provided with two of the degassing chambers separated by a cooling fluid, communication between the degassing chambers is prevented even if a pressure difference is increased between the degassing chambers.

Abstract: A method of producing a vacuum between two glass sheets to form an insulating glazing. One of the sheets has a hole drilled in its thickness. Spacers are placed between the two glass sheets with the sealing joint being placed around the periphery of the sheets. A vacuum is created between the sheets through the hole which is then closed. The spacers are fixed on one of the sheets by bonding with a mineral compound covering at least the bonding zones on the glass sheet. The second sheet is placed on the spacers and on the peripheral sealing joint. The peripheral sealing and the bonding with the spacers are simultaneously effected by raising the temperature.
