Patent number: 11235346Abstract: The facility includes a first connection mechanism connecting a filter unit to a floor discharging section to establish communication between an opening portion of the floor discharging section and an upper face opening portion of the filter unit and a second connection mechanism connecting the filter unit to an exhausting chamber to establish communication between an opening portion of the exhausting chamber and a side face opening portion of the filter unit. The first connection mechanism includes a seal portion that comes into contact with an entire circumference of an outer face of an upper end portion of the filter unit, thus preventing leakage of exhaust gas. The seal portion includes an introducing portion for introducing the upper end portion of the filter unit to the seal portion from a horizontal direction.Type: GrantFiled: August 27, 2020Date of Patent: February 1, 2022Assignee: Taikisha Ltd.Inventors: Kozo Ishida, Toshihiko Koike, Hisao Nakajima, Tomotaka Miwa, Hiroshi Iwakiri

Patent number: 9968956Abstract: By setting a robot installing area at a higher pressure than an adjacent painting area, there is formed an air flow which flows from the robot installing area into the painting area. With this, in a painting facility in which a painting object is painted by paint spraying from a sprayer while displacing the painting object held to an arm leading end portion of a painting robot relative to the sprayer by an action of the painting robot, adhesion of paint to the painting robot and to a painting area lateral wall is prevented.Type: GrantFiled: April 7, 2015Date of Patent: May 15, 2018Assignee: Taikisha Ltd.Inventor: Tomotaka Miwa

Patent number: 7740026Abstract: A thermal storage type gas treating apparatus has a high sealing performance while achieving a simple apparatus construction. The thermal storage type gas treating apparatus includes a valve member rotatable to place successively a supply port for a gas to be treated and an exhaust port for a treated gas formed in the valve member, in an opposed and communicating relationship with supply and exhaust ports formed in a distributor, thereby successively passing gas to be treated and treated gas through a plurality of thermal storage chambers communicating at one end with a combustion chamber. The valve member is supported to be displaceable toward and away from the distributor. A valve biasing device is provided for pressing the valve body to the distributor, while being inoperative with respect to a gas chamber device.Type: GrantFiled: June 28, 2005Date of Patent: June 22, 2010Assignee: Taikisha Ltd.Inventors: Yoshiaki Matsui, Yuji Nagata, Satoshi Horisawa, Tomotaka Miwa
