摘要： A delayed fracture is effectively prevented by appropriately setting a shape and working stress, and working environment of a high strength member having more than 1,000 MPa of tensile strength. For this end, the relationship between a maximum value of diffusible hydrogen contents of unfailed specimens (Hc) and Weibull stress are found and the content of diffusible hydrogen entered into steel from the environment due to corrosion during the use of the steel member (He) is also found. Then, Weibull stress in the Hc that is equal to the He is found, thus determining the shape and working stress of the steel member so as to provide stress below the Weibull stress.

摘要： A method of rolling a material in two more continuous passes is disclosed. The method includes rolling the material with a flattened-shaped caliber in a first pass, and subsequently rolling with a square-shaped caliber in a second pass. The rolling is performed with a first pass caliber having a flattened shape, wherein the ratio of the length (2A01) of minor axis of the first pass caliber to an initial width (2A0) is (A01/A0)≦0.75; and a second pass caliber, wherein the ratio of a diagonal dimension (2AS1) of the second pass caliber to the length (2B1) of the major axis of the material after the first pass is (AS1/B1)≦0.75 to introduce the large strain into the material.

摘要： A method of rolling with a flattened-shaped caliber in a 1st pass and subsequently roiling with a square-shaped caliber in a 2nd pass In a caliber rolling of two or more continuous passes. The rolling is performed with a caliber which sets the ratio of the minor axis (2A01) of a 1st pass flattened to a material opposite side dimension (2A0) to A01/A0≦0.75 and the ratio of a 2nd pass vertical diagonal dimension 2As1 to the major axis 2B1 of a material after the 1st pass to As1/B1≦0.75 to introduce the large strain into the material.

摘要： Mask layout data of a lithographic mask includes polygons that each include horizontal and vertical edges. Each of a number of target edge pairs is defined by two edges of one or more of the polygons. A search box having a boundary coincident with a given edge of the edges of the polygons is specified. Whether the search box includes at least one edge of the edges of the polygons in addition to the given edge is determined. Where the search box includes at least one edge, at least one of the target edge pairs is specified as including the given edge and one of the at least one edge. For each target edge pair that has been specified, a manufacturability penalty value is determined. A dynamic manufacturability constraint table and a non-zero multiplier table are maintained.
