Publication number: 20180185783Abstract: [Problem] Providing a carbon dioxide-containing gas recovery-apparatus which is low in cost and can improve a carbon dioxide-containing gas recovery efficiency. [Overcoming Means] A pump housing 11 of the carbon dioxide-containing gas recovery apparatus 10 is formed with a first chamber 23 and a second chamber 26 partitioned by a partition wall 20a. The first and second chambers 23 and 26 communicate with each other through a third chamber 20. The first chamber 23 communicates with a water supply opening and a carbon dioxide-containing gas inlet. When blown against water filling the first chamber, a carbon dioxide-containing gas is dissolved in the water, and the carbon dioxide-containing gas remaining undissolved exists as bubbles A in the water. When a pair of six-blade rotors 40 oppositely disposed on two axes 41a and 41b in the third chamber 20 compress the bubbles A to be refined into bubbles B, the carbon dioxide-containing gas can further be dissolved in the water by a compression action.Type: ApplicationFiled: June 21, 2016Publication date: July 5, 2018Inventors: Yasuna YOKOI, Toshiaki KATO, Hideyuki OKANO, Yoshinobu ITO

Patent number: 8961658Abstract: A mist/dust collector includes a tank body, a recovery tank having a demister member, a spraying unit spraying water or coolant fluid from a nozzle, an impeller mounted on a main shaft located in the tank body, so as to be rotatable by air flow, a disc rotary brush and a shaking-off member mounted on the shaft. A suction unit is actuated to draw air containing mist and dust into the tank body interior maintained in a negative pressure state. The impeller is rotated by collision of water or coolant fluid at a predetermined pressure, and the rotary brush and the shaking-off member are rotated simultaneously with the impeller, so that mist and dust are separated from air by a centrifugal action of the rotary brush and the shaking-off member. Mist and dust remaining in the air flowing into the recovery tank are collected by the demister member.Type: GrantFiled: December 17, 2013Date of Patent: February 24, 2015Assignee: Anlet Co., Ltd.Inventors: Yasuna Yokoi, Yoshinobu Ito, Toshiaki Kato, Kouiti Kume, Hideyuki Okano

Patent number: 7233331Abstract: A parallel processing system and method for performing processing tasks in parallel on a plurality of processors breaks down a processing task into a plurality of self-contained task objects, each of which has one or more “data-waiting” slots for receiving a respective data input required for performing a computational step. The task objects are maintained in a “waiting” state while awaiting one or more inputs to fill its slots. When all slots are filled, the task object is placed in an “active” state and can be performed on a processor without waiting for any other input. The “active” tasks objects are placed in a queue and assigned to a next available processor. The status of the task object is changed to a “dead” state when the computation has been completed, and dead task objects are removed from memory at periodic intervals.Type: GrantFiled: March 14, 2001Date of Patent: June 19, 2007Assignee: Square Enix Co., Ltd.Inventor: Toshiaki Kato
