A press-forming device includes a punch and a die, as a mold to be measured, and a strain measurement means arranged within the mold and measuring a strain amount generated by press-forming. The strain measurement means is positioned at the press-direction side relative to a radius end of a die shoulder on the material flow-out side when the mold is positioned at a lower dead point of press-forming. The strain measurement means is preferably positioned within a region defined by a surface which is away from the center of curvature of a curved surface of the mold by the distance ten times R, where R is a curvature radius of the curved surface.

The present invention provides a flame retardant polyester resin composition that is free from halogen and can have a high level of initial flame retardancy and maintain flammability even after a long-term heat aging test. By allowing an organophosphorous flame retardant (B) represented by the general formula (1) below: (where n=2 to 20) and a nitrogen compound (C) to be contained at a specific ratio with respect to a thermoplastic polyester resin (A), it is possible to obtain a flame retardant polyester resin composition that can have a high level of initial flame retardancy and maintain flammability even after a long-term heat aging test.

An object of the invention is to provide a simulation method and a simulation apparatus of the image of a twisted yarn capable of forming an image close to the actuality. When the images of twisted threads (1, 2) are inputted, abstracted models (3, 4) of the twisted yarns having a constant elliptical cross-section are obtained as shown in (b). A projected image (6) of the twisted yarns as shown in (c) is obtained when the models shown in (b) are viewed from the right side and one of two abstracted models (3, 4) located on the left side is concealed. The projected image (6) of the twisted yarns is formed by copying the images of the twisted yarns (1, 2) on to parts corresponding to the abstracted models (3, 4) of respective twisted yarns.
