According to an embodiment, a liquid ejection device that performs preprocessing to apply a processing liquid from an applying unit to a recording medium before ejecting a liquid droplet onto the recording medium to form an image, the liquid ejection device includes an acquiring unit and a correcting unit. The acquiring unit acquires a capture image that is of an image formed on the recording medium and that is captured by a capturing unit. The correcting unit corrects a state of the processing liquid applied by the applying unit based on a state of the liquid droplet indicated by the capture image.

A tooth groove is provided at a border portion between a tooth body portion and a protrusion. The angle between a tooth body portion lateral face which is a lateral face in the circumferential direction of the tooth body portion and a tooth body portion stop portion which is a face, of the tooth groove, continued from the tooth body portion lateral face is the right angle or an acute angle. The protrusion is rotated toward the outer side in the circumferential direction, to bring a protrusion stop portion into close contact with the tooth body portion stop portion, the protrusion stop portion being an outer-circumferential-side lateral face of the protrusion, thereby forming a shoe in a tooth.

The present invention provides an automotive dynamoelectric stator that enables vibration resistance of a lead portion to be ensured and reductions in area of the lead portion and a coil end group that is exposed to a cooling airflow to be suppressed without increasing work or cost. In a dynamoelectric machine according to the present invention, first lead portions that connect a plurality of windings to configure phase windings are each led axially outward from a rear-end coil end group, and then disposed so as to extend parallel to an axially outer peripheral surface of the rear-end coil end group so as to cross at least one other first lead portion, and so as to be separated from the axially outer peripheral surface of the rear-end coil end group.

Automotive dynamoelectric stator

Respective divided segments of a collet are moved radially outward by moving an arbor axially. The respective divided segments thereby press an inner circumferential surface of a stator core of a stator from radially inside such that the stator is held coaxially by the collet. Next, shaping rollers are lowered so as to press an outer circumferential surface of the stator core. The stator is rotated by rotating the collet in that state. Thus, the inner circumferential surface of the stator core is compressed and plastically deformed so as to conform to the collet and the outer circumferential surface of the stator core is compressed and plastically deformed by the shaping rollers, correcting the inner circumferential surface and the outer circumferential surface of the stator core so as to be coaxial and so as to have a high degree of roundness.

A manufacturing apparatus that executes the above steps is also disclosed.
