Patent number: 7226354Abstract: A cabinet wherein air sucked from an inlet opening 4d of a shelf board combined inlet duct 4 by drive of an air purification unit 3 is passed through the shelf board combined inlet duct 4 and introduced into the inside of a case 3a, and by a dust collection filter 32 and an odor eliminating means 33. Air forced into the shelf board combined outlet duct 5 through the air duct 10 is exhausted through an outlet opening 5d of the shelf board combined outlet duct 5, and air curtain is formed along the opening of the storage section 11 of a cabinet 1. Therefore, air in the storage section 11 of the cabinet 1 is circulated and purified, while getting caught in a circulating airflow including the air curtain.Type: GrantFiled: May 29, 2002Date of Patent: June 5, 2007Assignee: Kongo Kabushiki KaishaInventors: Tomoyuki Kawano, Toshihiro Higashi, Hiroaki Koba, Ichiro Ikenaga, Kazuya Tokunaga, Satoru Yoshimitsu, Hitoshi Shibuya

Patent number: 7032762Abstract: The invention provides a relatively simple and inexpensive power-assisted movable rack system, movement of which is controlled by an operator. The movable rack system comprises a plurality of movable racks, each of which includes a plurality of wheels, a DC motor turning forward or backward and reciprocating the movable rack, a pair of direction switches provided at opposite positions in moving directions of the movable rack, and an actuating circuit rotating the DC motor in one direction during the operation of one of the direction switches and rotating the DC motor in an opposite direction during the operation of the other direction switch. The DC motor applies dynamic braking force, so that movable racks can be stopped with a short braking distance.Type: GrantFiled: August 27, 2001Date of Patent: April 25, 2006Assignee: Kongo Co., Ltd.Inventors: Kunio Miyazaki, Tomoyuki Kawano, Kazuya Tokunaga, Ichiro Ikenaga, Toshihiro Higashi

Publication number: 20040035060Abstract: A number of embodiments of moveable storage racks and/or partitions that can be installed in existing buildings without the necessity of installing guide rails for them. In addition, the movement may be controlled so that the partitions move either in a parallel fashion or they can be rotated through an arc. The partitions are supported on drive and guide belts that are mounted on the underside thereof and which eliminate the need for the guide rails and spread the weight of the partition over a greater area of the floor so as to permit use in buildings which were not originally designed for such systems.Type: ApplicationFiled: February 9, 2003Publication date: February 26, 2004Inventors: Kunio Miyazaki, Tomoyuki Kawano, Takuya Nakamura, Michihiko Higashinozono, Ichiro Ikenaga, Hiroyuki Kiyota, Kazuya Tokunaga
