  • Patent number: 7981351
    Abstract: A method for thermally crystallizing a neck of a primary molded product for forming a bottle-shaped container made of polyethylene terephthalate as principal ingredient, said neck having a functional part and a neck ring at a lower end thereof, said functional part being formed with screw threads at an upper portion thereof and a bead ring below the screw threads, said method comprising: heating the neck, and then squeezing the bead ring heated to the heat-deformable temperature, from outside so as to form an outer diameter of the bead ring within a dimensional tolerance for deformation with regard to sealing effect.

  • Patent number: 5206673
    Abstract: A mirror Fresnel lens (12) is disposed on a base (11), on which a liquid crystal display (18) is mounted. The liquid crystal display (18) is provided with a polarization plate (24) only in the mirror Fresnel lens (12) side. Light from a light source (15) passes through the liquid crystal display (18), is reflected by the mirror Fresnel lens (12), again passes through the liquid crystal display (18), is converged by a projection lens 16 and reflected by the mirror (17) and eventually arrives at a screen (20). A separated polarization plate (25) is provided in a manner to overlap with the projection lens 16. The separated polarization plate (25) is paired with the polarization plate (24).
