Abstract: A method and apparatus determines an optimal design of an engineered structure formed of segments having different thicknesses. The techniques include receiving a design model for the engineered structure. The design model includes a finite element model of a spatial domain wherein the engineered structure is contained and an objective function to be optimized. Based on satisfying a converged objective function value and a lower bound of material density values, the techniques are able to produce a completed model of the engineered structure.

Abstract: The front part and the rear part of a diaper main body are each attracted by a first belt and a second belt arranged so as to separate from each other as the first belt and the second belt move to the downstream side of the conveying path. The diaper main body is attracted by the first belt only in a range other than a non-attracting range thereof covering from a crease to a prescribed position in a longitudinal direction. When the respective belts are moved, the front part and the rear part of the diaper main body are separated from each other in a state in which the diaper main body separates from the first belt in the non-attracting range. Then, respective side panels are folded inward between the front part and the rear part of the diaper main body that separate from each other.

A pair of shaping rolls that are parallel to each other include, on circumferential surfaces thereof, recessed and protruding shapes that mesh with each other at a face-to-face position. Rotating shafts of the pair of shaping rolls are cooperatively coupled with a rotational driving means through eccentric couplings. A downstream shaping roll includes, inside a roll main body, air passages that extend in a direction of a roll shaft center and air vent holes that connect the air passages to the circumferential surface. A communication member is disposed adjacent to the end of the roll main body and includes an air intake port that can communicate with the air passages in a first preset region in a circumferential direction, and an air supply port that can communicate with the air passages in a second preset region.

Abstract: First and second anvil rolls (10A, 10B) are arranged so that in the welding of webs, the webs are transported to pass through a first gap (?1) between the first anvil roll (10A) and a first horn (21), a third gap (?3) between the second anvil roll (10B) and a third horn (23), a fourth gap (?4between the second anvil roll (10B) and the fourth horn (24) and a second gap (?2) between the first anvil roll (10A) and the second horn (22) in this order.

Abstract: Partly-finished products having side panel pieces are supplied intermittently to places between welding surfaces of a horn and a rotating anvil. Thus, the side pieces of the partly-finished products, are welded continuously to each other with a predetermined pattern. The welding surfaces of the anvil are provided over an entire circumference about a rotating shaft so that the interval between the welding surfaces of the anvil and the horns is maintained at an interval at which the respective side panel pieces are continuously weldable to each other with the predetermined pattern regardless of a rotating position of the anvil.
