摘要： A compressor for a refrigeration machine is provided without any problems of reduction in the life of a thrust bearing structure even when a substitutive coolant not containing any chlorine is used. In the compressor for a refrigeration machine having a thrust bearing made of steel for supporting a thrust load applied to a drive shaft, a thrust bearing surface made of a material different from that of the drive shaft is formed in the thrust bearing by means of a surface treatment. Alternatively a washer defining the thrust bearing surface may be surface treated to provide a material different from that of the drive shaft. The washer may also be made of a material different from that of the drive shaft. According to the the present invention, even when a boundary lubricating state is produced between the drive shaft and the thrust bearing surface sticking is prevented. As a result, the life of the thrust bearing structure of the drive shaft can be made longer and a problem of reduction in the life of the thrust bearing structure can be avoided even when a substitutive coolant not containing any chlorine is utilized.

摘要： A lever is supported by a lever supporting portion. The lever is urged by a first spring and a second spring. The urging force of the first spring varies over the entire operational range of the lever. The second spring and a third spring are provided serially through a movable supporting member. The displacement of the movable supporting member is restricted by a fixed supporting member. If the urging force of the second spring exceeds the urging force of the third spring, the restriction on the displacement of the movable supporting member is removed. Therefore, the present configuration provides a player with feeling similar to that the player perceives when he manipulates a damper pedal of an acoustic piano.

摘要： A key structure includes a top plate which is formed by laminating a half-transparent resin surface layer member on a resin bottom side member using two-color injection molding, and the top plate is secured on a wooden key base. A plurality of concave grooves and protrusions, and a plurality of protrusion and troughs are respectively formed together in straight lines in the long direction of the key structure on a rear face of the surface layer member and a top face of the rear side member. Outside light is reflected from the top ends of the protrusion and the troughs, whereby a faint and natural vertically-striped pattern, which corresponds to a concave-convex part formed by the concave grooves and the protrusions, is perceived as resembling an edge grain of ivory.
