Abstract: A hot bulge forming die apparatus forms a preheated tubular material 10a into a tubular material 10d. The hot bulge forming die apparatus includes a lower die 21B having a cavity surface 211B and an upper die 31B having a cavity surface 311B. An elongated hole 215 is formed in a circumferential edge portion 215 of the lower die 21B so as to extend outwards, and a projection 315 is formed on a circumferential edge portion 314 of the upper die 31B so as to fit in the elongated hole 215. When the dies are clamped together, the projection 315 formed on the circumferential edge portion 314 of the upper die 31B fits in the elongated hole 215 formed in the circumferential edge portion 214 of the lower die 21B.

Abstract: In a hot bulge forming apparatus 1, a preheated tubular material 10b is disposed in a cavity 33A defined by dies 21A, 31A, air is supplied into an interior of the tubular material 10b so that the tubular material 10b is pressed against cavity surfaces 211A, 311A by the pressure of the air to thereby form the tubular material 10b into a shape defined by the cavity 33A. Thereafter, the resulting tubular material 10c is disposed in a cavity 33B defined by dies 21B, 31B, and air is supplied into an interior of the tubular material 10c so that the tubular material 10c is pressed against cavity surfaces 211B, 311B by the pressure of the air to thereby form the tubular material 10c into a shape defined by the cavity 33B while the tubular material 10c is cooled by the cavity surfaces 211B, 311B. Projecting portions 331 each having an arc-shaped section are formed at portions of the cavity surfaces 211A, 311A against which lengthwise end sides of the tubular material 10b are pressed.

Abstract: A print processing apparatus using a computer system, the computer system having: a computer; a printer connected with the computer; and a printer driver specific to the printer, for sending printing data from an application having a printing function to the printer directly or via an operating system, which print processing apparatus comprises: a display for displaying print setting items of the application and print setting items of the printer driver simultaneously on particular screens when printing operation is carried out using the application; and a print support software for extracting an overlapping item between the print setting items of the application and the print setting items of the printer driver so as to prevent contents of the overlapping item from conflicting with each other.
