Abstract: A unison ring of a gas turbine engine includes: an annular body including fiber-reinforced resin or circular-arc bodies including the fiber-reinforced resin, the fiber-reinforced resin including resin and reinforced fibers; and pin holes in which a pin is in a radial direction orthogonal to an axial direction of the unison ring. A main orientation of the reinforced fibers of the fiber-reinforced resin is directed in a circumferential direction of the unison ring.

Abstract: According to one embodiment, a semiconductor memory device includes a stacked layer body including conductive and insulating layers alternately stacked in a first direction, partition structures each extending in first and second directions in the stacked layer body, and an intermediate structure extending from an upper end and terminating at a position between upper and lower ends of the stacked layer body between adjacent partition structures. The partition structures include a first partition structure including first and second portions arranged in the second direction, the first portion extends from the upper end to the lower end, and the second portion is located between adjacent first portions, extends from the upper end and terminates at the position between the upper and lower ends.
