Abstract: Inclined surfaces are formed in areas adjacent to a tooth protruding from the inner circumferential surface of the yoke, on both sides in a motor rotation circumferential direction, and the inclined surfaces are inclined or curved toward a protruding direction of the tooth as a distance from the tooth increases in the motor rotation circumferential direction. The conductive wire includes parts extending in the motor rotation circumferential direction on both sides of the tooth in the motor rotational shaft direction in each of first to n-th turns, and bent portions bending in a thickness direction of the conductive wire are formed in the parts so as to align in a winding axis direction through the width of the conductive wire. Portions of the conductive wire on are inclined toward the protruding direction of the associated tooth as the distance from the bent portion increases in the motor rotation circumferential direction.

Abstract: An insulator includes a part to be wound with a coil of a wiring wire with a circular cross section; first and second flanges. The first flange is formed at the side of the part closer to a core segment. The second flange is formed at the side closer to a distal end of a tooth. The part to be wound with the coil has a slope continuous with the first flange and inclined so that a height from an upper surface of the tooth increases from the first flange toward the second flange.

Abstract: A microelement includes: a base being a body of the microelement, the base including a liquid inlet for a liquid to be introduced, a liquid outlet for the liquid to be discharged, and a groove for the liquid to flow from the liquid inlet toward the liquid outlet; a cover that covers the groove of the base; and a liquid flow controller film segment that is fixed to an inner surface of the cover so as to be opposite to the groove. The liquid flow controller film segment is arc-shaped curved-band-like extending in a direction crossing a flow direction of the liquid and has a radius about a center-corresponding position of the cover corresponding to a center of the liquid outlet of the groove. The liquid flow controller film segment is exposed in the groove and disposed on the downstream side to an exposed surface at the inner surface of the cover in the flow direction of the liquid in the groove. The liquid flow controller film segment has a contact angle that is greater than a contact angle of the exposed surface at the inner surface of the cover.

Abstract: An insulator includes a part to be wound with a coil; a first flange; and a second flange. The first flange is formed at the side of the part closer to a core segment, and includes a coil guide groove that guides the coil to the part. The second flange is formed at the side of the part closer to a distal end of a teeth. The coil guide groove includes a first guide groove and a second guide groove symmetrical with respect to a radial plane. Each of the first and second guide grooves and—extends at an acute angle from an inner surface of the first flange.

Abstract: A coil is a coil of a conductive wire that has a quadrangular cross section, that is spirally wound and laminated to have a series of turns including first to n-th turns (n is an integer of 3 or more), and that is provided, on at least some of the first to n-th turns in the coil, with deformed portions representing recesses each having a shape different from a shape of another portion of the conductive wire. In each of the first and n-th turns respectively lying at both ends of the series of turns, an outer surface lying on a side opposite to a center of the series of turns extends flush along with a plane intersecting the series of turns.

Abstract: A coil device includes a first coil including a plate-shaped first coil body having a first and second end. The first coil body is spirally wound on a columnar portion along the extending direction of the columnar portion such that the second end is positioned on one side in the extending direction relative to the first end. The coil device further includes a second coil including a plate-shaped second coil body having a third end and a fourth end. The second coil body is spirally wound on the columnar portion along the extending direction such that the third end is positioned on the one side in the extending direction relative to the second end of the first coil, and the fourth end is positioned on the one side in the extending direction relative to the third end. The second coil is in electrically parallel connection with the first coil.
