A ceramic top coat is formed over a heat resistant alloy including Ni as a main component through a bond coat which contains Ni essentially as a main component, Cr, and Al. The alloy for the bond coat can include Si in the range from 0 to 10 wt.%. As a result, in a long time operation, the spalling damage of a ceramic top coat is not easily created and the deterioration of the mechanical properties is small.

The invention provides a laminated core 10 including a plurality of segment core sheets 13 spirally wound and laminated in layers while connecting portions 12 connecting the adjacent segment core sheets 13 are bent, ends of the segment core sheets 13 are aligned with each other and the connecting portions 12 in the adjacent layers are circumferentially displaced relative to each other, the connecting portions 12 located in outer peripheral areas 11 of the segment core sheets 13, the laminated core 10 comprising: a concave cutout 22 formed on a radially outward side of the connecting portion 12, the concave cutout 22 accommodating a radially expanded part 21 within an outer circle of the laminated core 10, the radially expanded part 21 formed in the connecting portion 12 radially outward atthe bending of the connecting portion 12; an interior cutout 23 formed on a radially inward side of the connecting portion 12, the interior cutout 23 defining a bent position of the connecting portion 12; and depressed receptacles 16, 17 respectively formed on a top side and a bottom side of a radially outward area of the segment core sheet 13 except for the connecting portions 12, the depressedreceptacles 16, 17 each receiving a thickness-direction expanded part 15 formed in the connecting portion 12 in a thickness direction thereof at the bending of the connecting portion 12.

A composite motor includes: a rotor of at least for polarities in which N pole and S pole are alternately arranged in the circumferential direction; a stator core having stator magnetic circuits which are magnetically separated in a range of 360 degrees of electrical angle; and (N-1) sets of winding of an N-phase motor (N is a positive integer). The composite motor is configured so that the current in the windings effectively functions on the magnetic circuits.

The invention provides an scroll expander to improve both the reliability and performance. Lubricating oil 6 held at a suction pressure is supplied into a counter-lap side end plate rear face 13d of a revolving scroll 13. Communicating passages 30a and 30b to communicate the end plate rear face 13d and the lap bottom 13b of the revolving scroll center portion are formed to the end plate 13a. Thereby, since the lubricating oil 6 is supplied into a suction part, and discharged lubricating and sealing a fixed scroll 12 and the revolving scroll 13 successively following the expansion process, so as to provide the relible scroll expander.

In the present invention, a mixed powder (100) filling the inside of a container cavity (24) is transferred into the cavity of a first die, a first applied pressure is applied to the mixed powder (100) in the first die (31), molding an intermediate powder compact (110), the post-molding first die (31) and intermediate powder compact (110) are heated, causing the intermediate powder compact (110) to be warmed to the melting-point-equivalent temperature of a lubricant, the post-warming intermediate powder compact (110) is transferred into the cavity of a second die (61) and a second applied pressure is applied, thus molding a high-density completed powder compact.

Provided is a compressor equipped with an oil separation mechanism unit (40) that separates oil from a refrigerant gas discharged from a compression mechanism part (10), with the oil separation mechanism unit (40) having: a cylindrical space (41) in which the refrigerant gas is caused to rotate; an inflow part (42) that introduces the refrigerant gas discharged from the compression mechanism part (10) into the cylindrical space (41); a delivery outlet (43) that delivers the refrigerant gas, from which the oil has been separated, from the cylindrical space (41) to one space (31) within a container; and a discharge port (44) that discharges the separated oil from the cylindrical space (41) to the other space (32) within the container. The delivery outlet (43) is provided with an impactor (49) with a prescribed distance therebetween. Thus, the electric motor part is highly efficient, and the compressor has improved volumetric efficiency and low oil circulation.
