Patent number: 9869614Abstract: A sampling apparatus includes a pressure-reducing safety unit, which includes a device accommodation chamber that accommodates safety devices and a cylinder connection chamber, and a cylinder unit. The cylinder unit removably accommodates a cylinder, excluding an exposed portion where a front end portion of the cylinder, a mouthpiece, and a cylinder on-off valve are exposed, in an openable/closable casing. The exposed portion of the cylinder is formed so as to be insertable from the open surface portion of the cylinder connection chamber into the cylinder connection chamber, the mouthpiece of the cylinder and a hydrogen outlet of a supply pipe of the device accommodation chamber are connected by using a flexible hose, and thereby a sample of hydrogen gas is taken into the cylinder.Type: GrantFiled: June 8, 2017Date of Patent: January 16, 2018Assignee: IWATANI CORPORATIONInventors: Kazuto Matsumoto, Shinichi Omoteda, Ken Nishida, Goichi Inoue

Patent number: 8012241Abstract: The present invention provides a method and an apparatus for condensing ozone arranged so as to efficiently take out the ozone gas of a predetermined concentration, although its construction is simple. The method for condensing the ozone gas comprises acting ozone-oxygen mixture gas on an adsorbing cylinder which is filled in its interior area with an adsorbent so as to selectively adsorb the ozone gas to an adsorbent and desorbing the selectively adsorbed ozone gas so as to condense and purify the ozone gas. The method further includes acting the ozone-oxygen mixture gas on the adsorbent in non-cooled state to selectively adsorb the ozone gas to the adsorbent and vacuuming the adsorbing cylinder on performing desorption-operation of the ozone gas to desorb the ozone gas from the adsorbent.Type: GrantFiled: November 24, 2006Date of Patent: September 6, 2011Assignee: Iwatani CorporationInventors: Kunihiko Koike, Sadaki Nakamura, Koichi Izumi, Goichi Inoue

Patent number: 6344130Abstract: A method for generating highly concentrated ozone gas by adsorbing ozone gas generated by an ozonizer with an absorbent within an adsorption column and then separating highly concentrated ozone gas from the adsorption column. Three adsorption columns are arranged in parallel. Each of the adsorption columns is controlled to repeat four steps of an ozone gas adsorbing step, a stabilizing and pressurizing step, an ozone gas desorbing step and a cooling down step. Each of the ozone gas adsorbing step and the ozone gas desorbing step has operation time set twice the operation time of each of the stabilizing and pressurizing step and the cooling down step. An ozone gas concentrating unit comprises three adsorption columns which are set to operate one after another by ⅓ cycle lag. Highly concentrated ozone gas separated at the desorbing step of each adsorption column is once stored in an ozone gas storage vessel.Type: GrantFiled: November 19, 1999Date of Patent: February 5, 2002Assignee: Iwatani Sangyo Kabushiki Kaisha (Iwatani International Corporation)Inventors: Kunihiko Koike, Goichi Inoue, Tatsuo Fukuda
