The optical film includes, in the following order, a base material, an alignment film, and a liquid crystal layer, in which the alignment film contains at least one specific compound selected from the group consisting of a polymerizable macromolecule having a polymerizable group in a side chain and a polymer thereof, and a secondary ion intensity derived from the specific compound in the alignment film is measured by a time-of-flight secondary ion mass spectrometry while irradiating the alignment film with an ion beam from a surface on a liquid crystal layer side toward a surface on abase material side, a maximum value of the secondary ion intensity derived from the specific compound is present in a region from the surface of the base material to a 100 nm thickness position.

Abstract: A method of manufacturing an armature coil includes steps of arranging a plurality of coil conductors of the armature coil between an end metal die and a back portion metal die on a lower metal die; pressing, with the upper metal die in a pressing direction, the plurality of the coil conductors arranged between the end metal die and the back portion metal die on the lower metal die; and removing coil conductors that become formed in a convex shape and a concave shape from the lower metal die. The upper metal die may be provided with an inclined portion on a lower metal die side of the upper metal die, and the upper metal die may be configured to be pressed such that a space is formed by the dies, the space having a width that gets gradually narrower.

Abstract: Provided is in an armature coil formed by arranging a plurality of coil conductors on a lower metal die having a tapered groove that is narrower toward an inner side. The coils are pressed using an upper metal die having an end portion narrower than the width of the groove.

Abstract: 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.

Abstract: Provided is a coating apparatus, which has satisfactory operability at a time of installing or exchanging a spray nozzle, is not complicated in structure, and is advantageous in terms of layout. A rotary drum (2) is rotated around an axis (A) inclined with respect to a horizontal line, and has an opening (5) at one end on an inclination upper side. A spray nozzle unit (10) is removably attached to a swing arm (34), and the swing arm (34) can swing with respect to a swing axis (34c). Owing to the swing operation of the swing arm (34), the swing nozzle unit (10) can be moved between the inside and the outside of the rotary drum (2).

Abstract: A method of manufacturing a stator of a rotating electric machine includes a conductor end shaping process for shaping multiple lead wires aligned side by side in a single layer into a specific form in a plane in which the lead wires are initially aligned before a flat-patterned winding assembly configured by aligning multiple line conductors side by side and shaping the line conductors in spiral form is fitted into multiple slots formed in a flat stator core plate. The shaping process includes the steps of shaping the lead wires into bent form by using a stairstep conductor shaping jig under conditions where the lead wires are separated from one another along a direction generally perpendicular to the plane in which the lead wires are initially aligned, and causing the lead wires to return to positions in the initial alignment plane thereof by removing the stairstep conductor shaping jig.
