摘要： A centrifugal fan is provided that includes a main plate configured to be rotated about a rotational axis, a shroud, having a suction opening, and a plurality of blades arranged in a circumferential direction between the main plate and the shroud to allow air suctioned in through the suction opening to flow from a front edge to a rear edge of each blade. Assuming a first cross section, a second cross section, a third cross section, and a fourth cross section of each blade sequentially taken at layers from the shroud to the main plate, a front edge of the first cross section is located farther from the rotational axis than a front edge of the fourth cross section, and a rear edge of the first cross section is located closer to the rotational axis than a rear edge of the fourth cross section.

摘要： In certain embodiments described herein, a heated line forming system includes a heating coil system configured to produce a heated line on a surface of a metal part. The heated line forming system also includes an air knife cooling system configured to maintain a dry area for the heated line, and to direct a coolant (e.g., cooling water, liquified gases such as liquid argon, solidified gases such as carbon dioxide snow, and so forth) around the heated line via a spray mechanism such that the coolant does not flow or splash into the heated line on the metal part. In certain embodiments, the heated line forming system includes multiple induction coils arranged along a line and spaced a short distance apart, but which, when operated simultaneously together, form a heated line on a surface of a metal part.

摘要： A method for forming an undercut portion of a formed article formed by plastically deforming a plate-shaped workpiece and a method for manufacturing a formed article having an undercut portion are provided. In these methods, the undercut portion is formed by press working performed using a punch and a die. These methods make the forming work more economical and more efficient. An outer portion of a plate member 91 (plate-shaped workpiece) located outward of a portion where an inwardly inclined portion 94 (undercut portion) is to be formed is bent by an angle determined such that an undercut surface 94a which constitutes the inwardly inclined portion 94 becomes parallel to the pressing direction of a punch 110. In addition, a peripheral wall portion 93 inclined by an angle corresponding to the bending angle is formed on the outer portion. The bent portion of the plate member 91 having the inclined peripheral wall portion 93 is bent back in the opposite direction so as to cause the inwardly inclined portion 94 to rise up from the surface of the plate member 91.
