摘要： To provide a can manufacturing pump impeller in which a stress of a base portion of a blade is prevented from increasing while improving the strength of a joint portion of a hub and a boss. In order to reinforce a joint portion of a hub and a boss, a plate is jointed to the inside of an impeller. In order not to overlap a base portion of a blade and the plate with each other on the hub, an opening portion is provided in the plate around the base portion of the blade on the hub. As a shape of the opening portion, a semicircular shape, a semielliptical shape, a rectangular shape, or a trapezoidal shape can be selected. Further, as a plate shape, a flat plate structure, a shell structure, or a curved structure can be selected.

摘要： A hollow stepped article is formed from a solid blank to reduce the material cost, and cracking is prevented in a stepped portion of large diameter when a portion of the blank is de-formed by its radial expansion. A hollow, stepped shaft is formed by holding an upper and a lower part axially of a solid rod-like blank with an upper and a lower die, respectively, which have a stepped recess of large diameter in a region where they are op-posed to each other; compressing the blank from both its axially opposite sides with an upper and a lower punch each of which is smaller in diameter than the blank, thereby extruding the blank so that an axial hollow is formed therein about its axis in each of its upper and lower parts and that a portion of the blank op-posed to the stepped recess of large diameter expands in diameter and deforms into that recess while leaving a solid plug-like portion between the punches; and thereafter further compressively moving one of the punches to shear the solid plug-like portion and force it out of the blank, whereby the blank is formed with a stepped portion of large diameter by radially expanding deformation in a region intermediate between its op-posed ends or at one of these ends and with a continuous axial hollow about its axis.

摘要： An imaging device is composed of a main body casing and a monitor casing, which coincide with each other in their lengthwise direction when not in use at a first position and which, when in use at a second position, are swung relative to each other about a first pivot such that their lengthwise directions form an angle of 90 degrees. The monitor casing is made up of a first casing in which there exists the first pivot and a second casing which is joined to the first casing such that it swings about the second pivot. The first pivot is placed at a position displaced toward the left lateral side from the center of the width of the main body casing so that the second casing is positioned outside the left lateral side of the width of the main body casing when in use at the second position.
