    Abstract: A wide-neck synthetic resin container has a neck, a body and a bottom. A top side of the neck is sealed by a cap. The neck includes a neck tubular section, an engagement section protruding outward therefrom and engaging the cap, and a flange protruding outward at the top side. The flange protrudes less than the engagement section. The neck's top side includes a first top side formed by the neck tubular section, and a second top side formed by the flange that is the same height level with the first top side and increases an area of the top side. The neck tubular section has a uniform thickness at an area immediately below the flange and an area where the engagement section is formed. A thickness of the flange is smaller than that of the neck tubular section, and the neck has been crystallized.

  • Patent number: 9802729
    Abstract: A blow molding method includes a primary blow molding step that molds a preform (200) in a primary blow mold (300A) that includes a primary temperature control section (330) to obtain an intermediate molded article (202), a shrinkage step that discharges blow air from the intermediate molded article to shrink the intermediate molded article, and a secondary blow molding step that blow-molds the intermediate molded article (204) that has shrunken in a secondary blow mold that includes a secondary temperature control section (430) to obtain a final molded article.

  • Patent number: 9358739
    Abstract: An invention of a method for production of a heat-resistant container, in which a raised bottom portion is displaced inwardly by reduction in internal pressure, is disclosed. The method is characterized by forming a raised bottom portion 11 smaller in wall thickness than a surrounding wall portion 12a by first blow molding using a heat-treating blow mold; and pushing up the raised bottom portion 11 by a secondary bottom mold, in performing second blow molding using a final blow mold, to increase the wall thickness of the surrounding wall portion 12a (ground portion 12) relative to the raised bottom portion.

  • Publication number: 20160096309
    Abstract: A neck crystallization method includes inserting a core into the neck, heating the neck using a heater group disposed along a transfer direction while rotating the preform on its axis, and transferring the preform along the transfer direction in a state in which the core is inserted into the neck, and cooling the neck of the preform in a state in which the core is inserted into the neck. The heating of the neck includes a first step that drives first heaters positioned on the upstream side in the transfer direction at a first power, and a second step that drives second heaters positioned on the downstream side of the first heaters at a second power that is lower than the first power until the temperature of the neck reaches a crystallization temperature zone.

  • Patent number: 8766705
    Abstract: An arrangement for detecting local light irradiation in an illegal attack attempt to intentionally induce a malfunction or faulty condition is formed on a small chip occupancy area so as to provide high detection sensitivity. In a region containing a logic circuit, a plurality of series-coupled detection inverters are distributively disposed as photodetector elements having a constant logical value of primary-stage input. When at least one of the series-coupled detection inverters is irradiated with light, an output thereof is inverted, thereby producing a final output through the series-coupled detection inverters. Based on the final output thus produced, local light irradiation can be detected.

  • Patent number: 8121013
    Abstract: An optical pickup apparatus changes a propagation direction of luminous fluxes, out of a laser light reflected by a disc, in four luminous flux regions set about a laser optical axis so as to mutually disperse these luminous fluxes. A signal light region in which only a signal light is present appears on a detection surface of a photodetector. A plurality of sensors for a signal light are placed at positions irradiated with the signal light within the region. When an arithmetic process is performed on a detection signal outputted from each sensor, a DC component occurring in a tracking error signal is suppressed.

  • Patent number: 8098704
    Abstract: A monolithic red/infrared semiconductor laser device is joined to a blue-violet semiconductor laser device. The distance between a blue-violet emission point in the blue-violet semiconductor laser device and an infrared emission point in an infrared semiconductor laser device is significantly shorter than the distance between a red emission point in a red semiconductor laser device and the infrared emission point. A blue-violet laser beam, a red laser beam, and an infrared laser beam respectively emitted from the blue-violet emission point, the red emission point, and the infrared emission point are introduced into a photodetector after being incident on an optical disk by an optical system comprising a polarizing beam splitter, a collimator lens, a beam expander, a ?/4 plate, an objective lens, a cylindrical lens, and an optical axis correction element.
