摘要： A grinding apparatus for grinding a spline ball groove on a workpiece comprises a rod-shaped grindstone, having a distal end portion with a curved surface corresponding to the groove to be ground, and a spindle mechanism for rotating the grindstone. The spindle mechanism and the grindstone are supported by means of a supporter in a manner such that they are inclined at a given angle to an axis of the workpiece. A rotary dresser, which has a dress groove corresponding to the curved surface of the distal end portion of the grindstones is disposed near the grinding apparatus. The grindstone can be reciprocated along the axis of the workpiece by a drive mechanism between the workpiece and the dresser without changing its angle of inclination.

摘要： In a linear motor, a can has a two-layer structure including an inner can 2 and an outer can 3, and an inner passage 7 formed between an armature winding 9 and the inner can 2 and an outer passage 8 formed between the inner can 2 and the outer can 3 are constituted by each can. Communicating portions 7A and 8A for causing the inner passage 7 and the outer passage 8 to communicate with each other are provided in the vicinity of a refrigerant supply port 5 in each of the cans 2 and 3 in such a manner that a refrigerant supplied from the refrigerant supply port 5 branches into the inner passage 7 and the outer passage 8 and thus flows. Consequently, it is possible to obtain a linear motor armature and a linear motor having a high cooling capability which can prevent the deformation of the can by using a conventional inactive refrigerant to improve the passage for the refrigerant.
