Publication number: 20120055360Abstract: 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).Type: ApplicationFiled: March 30, 2010Publication date: March 8, 2012Applicant: FUJIFILM CorporationInventors: Mitsuru Mushano, Masashi Norimatsu, Shuichi Otsuka

Publication number: 20120017787Abstract: 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.Type: ApplicationFiled: March 30, 2010Publication date: January 26, 2012Applicant: FUJIFILM CorporationInventors: Mitsuru Mushano, Masashi Norimatsu, Shuichi Otsuka

Patent number: 7175399Abstract: 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.Type: GrantFiled: July 2, 2003Date of Patent: February 13, 2007Assignee: Minebea Co., Ltd.Inventors: Kaoru Matsumoto, Shuichi Otsuka

Patent number: 6939113Abstract: 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.Type: GrantFiled: April 14, 2003Date of Patent: September 6, 2005Assignee: Minebea Co., Ltd.Inventors: Shuichi Otsuka, Jinko Ikeda

Patent number: 6866473Abstract: 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.Type: GrantFiled: April 10, 2003Date of Patent: March 15, 2005Assignee: Minebea Co., Ltd.Inventor: Shuichi Otsuka
