  • Publication number: 20120055360
    Abstract: In a relief printing plate according to an aspect of the present invention, the relief can be formed to have resistance to pressure applied to the apex thereof thanks to the depth (d) and the ridge tilt angle (x). In particular, the resistance to pressure against a relief serving as a highlight halftone dot can be improved to prevent the relief from falling over by the pressure applied to the apex of the relief. Thereby, the relief serving as a highlight halftone dot can be made not to be dipped in a cell of the ink roller (e.g., anilox roller).

  • Publication number: 20120017787
    Abstract: According to an aspect of the invention, on the relief printing plate where a relief serving as a halftone dot is formed on a surface of a plate material, an elliptical frustoconical relief is formed as the relief as well as the minor direction of the elliptical frustum matches the printing direction so that the longitudinal section of the relief in the same direction as in the printing direction is smaller than the longitudinal section of the relief in a direction orthogonal to the printing direction. Thereby, the relief having the aforementioned sectional shape has resistance to pressure as a whole of the relief as well as flexibility in the printing direction.

  • Patent number: 7363235
    Abstract: The image storing apparatus stores an image uploaded from a customer via a network on a large-capacity medium by associating it with customer information indicating the customer, image attribute information or image selection information so as to manage the image of the customer. And if capacity, quantity, a recording period or a current date of the images of a certain customer exceeds a predetermined threshold, one image or a plurality of images of the customer are moved to another medium so as to secure storage capacity of the above described large-capacity medium.

  • Patent number: 7175399
    Abstract: An apparatus for a serial ventilation device that increases airflow compared to conventional devices without increasing the size is presented. The first ventilator is mounted on the intake opening side of the serial ventilation device, with the front surface of its blades facing the air intake side. The second ventilator is mounted on the exhaust opening side of the serial ventilation device, with the front surface of its blades facing the air exhaust side. Thus a first ventilator, which ventilates from the rear side of the ventilator, and a second ventilator, which ventilates from the front side of the ventilator, operate as a whole. Both ventilators are connected serially such that their rotation shafts are positioned coaxially, while the number of blades of the two ventilators are different.

  • Patent number: 6939113
    Abstract: A fan with increased air flow having a casing in which an air passage hole is formed. A motor is connected to this casing and is held in the center of the air passage hole by a motor base positioned within the air passage hole. Multiple blades are rotated by the motor and covey air from the air passage hole intake port side to the exhaust port side. The annular outer wall of the fan is inclined with respect to the center axis towards the air passage hole exhaust port. By this means, a fan is capable of attaining a greater airflow volume than conventional fans, while having the same outward shape as a conventional fan.

  • Patent number: 6866473
    Abstract: This invention is designed to reduce a harsh noise, by suppressing a wind noise generated at a wind-receiving end, which is caused by forming the wind-receiving end of an outlet port for air so as to be parallel to a side extending along the direction of the rotation axis of a vane of an impeller. The wind-receiving end of the outlet port is provided in the form of steps or with inclination with respect to a side extending along the direction of the rotation axis of a vane of the impeller so that the wind sent and blown out by the vanes of the impeller is prevented from blowing against the wind-receiving end all at once throughout its entire width.

  • Patent number: 6655918
    Abstract: In an impeller of an axial-flow blower driven by an outer rotor type motor, the impeller is formed in sections so that individual impeller sections 5F and 5R can easily be formed by molding with an axial coupling type die, and also which are arranged in series to construct the entire impeller, thereby realizing an impeller structure in which adjacent impeller blades overlap each other. The number of impeller blades of the front section impeller is more than that of the rear section impeller to reduce the noise generated during the rotation of the impeller.

  • Patent number: 6511300
    Abstract: An impeller arrangement in which adjacent blades (ventilating surfaces) are overlapped with each other as viewed in the axial direction is realized easily and cost-effectively even in a synthetic-resin-molded product. In an impeller for an axial flow type blower driven by an outer rotor type motor which is integrated to a rotatably supported shaft and a motor yoke to be rotated about the shaft around an outer side of a stator together with the motor yoke for ventilation, the impeller comprises a plurality of impellers (divided impellers, for example, a front side divided impeller and a rear side divided wheel), so that each of the divided impellers can be molded by a simple molding method using axially coupled type metal dies.
