    Abstract: PROBLEM TO BE SOLVED: To propose a ceramic bushing reducing conventional defects.
    SOLUTION: This invention relates to a ceramic-based bushing 10 for mounting in a turbomachine casing to provide a smooth bearing for a pivot of a variable-pitch vane. The bushing is constituted by a metal jacket 11 and a ceramic ring 16 secured to the inside wall 11a of the metal jacket 11 by brazing. The invention also provides a turbomachine compressor having variable-pitch stator vanes with pivots mounted in the casing by means of such bushings.

    Abstract: PROBLEM TO BE SOLVED: To provide a compressor exerting an excellent compression function for a long period of time, by surely suppressing an addition reaction of refrigerant containing a compound having carbon double bond. SOLUTION: The compressor uses the refrigerant containing the compound having double bond. The compressor uses, as a coat layer of an internal constructional element of the compressor, any one of Fe-P electroplating coat, Fe-W electroplating coat, Fe-C electroplating coat, Fe-N electroplating coat, Co electroplating coat, Co-W electroplating coat, Cr electroplating coat, Cr-Mo electroplating coat, resin coating film, and a DLC surface treatment coat.

    Abstract: PROBLEM TO BE SOLVED: To provide a system for preventing wear on a tip shroud 106 of a turbine blade 100 in a turbine engine. SOLUTION: This system includes a pocket 212 formed in a contact surface 200 of the tip shroud 106 and a plug 211 that fits within the pocket 212 and has a durable outer surface 214. The durable outer surface 214 may include a cobalt-based hardfacing powder. The pocket may be machined out of the contact surface 200, and the plug 211 may include a plug of predetermined size that fits snugly into the pocket 212. In some embodiments, the durable outer surface 214 may substantially align with the contact surface 200 after the plug 211 is fitted into the pocket 212. In other embodiments, the durable outer surface 214 may remain slightly raised from the contact surface 200 after the plug 211 has been fitted into the pocket 212. COPYRIGHT: (C)2008,JPO&INPIT
