Abstract: A flexible member is provided which can have excellent load resistance and flexibility while being more compact. This flexible member has a main body part in which multiple wave washers having closed ring shapes is stacked in an axial direction and joined to each other by multiple joint parts, and the main body part is able to be bent with respect to the axial direction due to elastic deformation of the wave washers. Each of the joint parts includes: a pair of welded parts in linear shape, being gradually separated from each other in a circumferential direction from an inner circumferential side toward an outer circumferential side of the wave washer.

Abstract: Disclosed is a stage including a shaft, a first supporting plate over the shaft, a heater arranged in a trench formed in the first supporting plate, and a gas-supplying tube arranged in the shaft and configured to blow a gas to the first supporting plate. The first supporting plate may have a disk shape, and a cross section of the gas-supplying tube parallel to a surface of the first supporting plate may overlap a center of the disk shape. The first supporting plate may be configured to block the gas so that the gas is not released to a chamber in which the stage is arranged.

Abstract: A rotor includes a rotor core configured by laminated steel plates and a magnet insertion hole extending along an axial direction of the rotor core, with a resin interposed between a permanent magnet placed in the magnet insertion hole and an inner wall face of the magnet insertion hole. In a manufacturing method for this rotor, in a first process, the permanent magnet and the resin are integrated together to manufacture a resin-coated permanent magnet that is capable of being press-fitted into the magnet insertion hole. Next, in a second process, the resin-coated permanent magnet is press-fitted into the magnet insertion hole. Next, in a third process, the post-second-process rotor core is heated to a temperature that is at least the temperature at which the resin softens. Accordingly, the softened resin is pressed in a rotor radial direction against the inner wall face of the magnet insertion hole and deformed so as to be fitted closely against undulations of the inner wall face of the magnet insertion hole. Next, in a fourth process, the post-third process rotor core is cooled.
