Abstract: According to one embodiment, a superconducting coil apparatus comprising at least one superconducting coil formed of a plurality of turns under a definition that one turn is a portion of a superconducting wire annularly wound for one round, wherein: the superconducting coil has a shape along an outer peripheral surface of a tubular structure having a tubular shape; each of the plurality of turns has a coil longitudinal portion extending along an axial direction of the tubular structure and a coil end portion extending from the coil longitudinal portion along a circumferential direction of the tubular structure; and a boundary line indicating a border between the coil longitudinal portion and the coil end portion at each of the plurality of turns is inclined with respect to a reference line extending in the circumferential direction of the tubular structure in a side view of the tubular structure.

Abstract: Provided is a cosmetic liquid applicator that allows easy determination as to the completion state of replacement of an application liquid tank. The cosmetic liquid applicator includes a front barrel to which an application liquid tank for storing a liquid cosmetic to be fed to an applying part is attached and a rear barrel attached to the front barrel to cover the application liquid tank. The front barrel has on its peripheral surface a male threaded portion and a first engagement portion formed in the circumferential direction and located in the rear of the male threaded portion while the rear barrel has on its inner circumferential surface a female threaded portion to mate with the male threaded portion and a second engagement portion to be engaged with the first engagement portion.

Abstract: A fuel injector has a body extending in an axial direction. The body includes: an axial passage formed so as to extend in the axial direction; a radial passage formed so as to communicate at one end with the axial passage and to open at another end to an outer surface of the body; and an internal passage including a first opening and a second opening open to the outer surface, and formed so as to extend inside the body from the first opening to the second opening. The first opening and the second opening are located opposite to each other across a third opening, through which the radial passage opens to the outer surface, in a circumferential direction centered on an axis of the body.

Abstract: An object is to provide a chlorinated polyolefin resin that has excellent solution stability and excellent adhesion to polyolefin substrates including a polyethylene substrate. The chlorinated polyolefin resin is a chlorinated product of a copolymer having a structural unit derived from ethylene, in which a content ratio of the ethylene structural unit in the copolymer is 50 mol % to 90 mol %.
