Abstract: A lathe system includes a spindle capable of gripping a bar and moving back and forth in an axial direction of the bar and a tool post to which a first tool is attached. The lathe system can manufacture a plurality of products having an identical shape from the bar by repeating a machining of the bar, a cutting off of a machined portion of the bar, and a grip change by the spindle, the grip change by the spindle comprising releasing the bar, moving back, and re-gripping the bar at a predetermined gripping position. The lathe system further includes a gripping position selecting unit capable of selecting a special gripping position at which the spindle re-grips the bar when a state of the machine tool system meets a predetermined condition, the special gripping position being different from the predetermined gripping position.

Abstract: A free-standing liner unit (1) is formed by integrating a planar outer tank liner plate (2), a planar secondary barrier plate (3), and a cold insulator layer (4) that is interposed between the outer tank liner plate (2) and the secondary barrier plate (3) into a single unit. According to this free-standing liner unit (1), when building a tank, it is possible to shorten the construction period by performing the formation of the outer tank shell plates and the formation of the tank internal structure concurrently with each other, and to achieve an improvement in the handleability of the free-standing liner unit (1).

Abstract: A method for constructing a cylindrical tank which has a metallic inner tank and a concrete outer tank includes a step of building up a PC wall in an outer circumferential edge portion of a base plate, a step of assembling an outer tank roof on the base plate other than the outer circumferential edge portion of the base plate, a step of lifting the outer tank roof which is on the base plate using a jack-up unit while the PC wall is being built up and then holding the outer tank roof on the PC wall, and a step of assembling the inner tank independently of the outer tank roof in a space under the outer tank roof which is created due to the lifting.
