Patent number: 10345014Abstract: Disclosed herein a technique for producing a gas mixture for controlling an oxygen concentration in the interior of a container while reducing the overall weight of the apparatus. For this purpose, a gas mixture supply device is provided for a container refrigeration apparatus. The gas mixture supply device is provided with adsorption columns. If one of the first and second adsorption columns is supplied with air, the adsorption columns are pressurized, and nitrogen in the air is adsorbed onto an adsorbent. If air is sucked from the other of the first and second adsorption columns, the adsorption columns are depressurized, and nitrogen adsorbed onto the adsorbent is desorbed. A gas mixture including the nitrogen desorbed from the adsorbent is supplied to the interior of a container.Type: GrantFiled: September 16, 2014Date of Patent: July 9, 2019Assignee: Daikin Industries, Ltd.Inventors: Naohiro Tanaka, Atsushi Ozato, Makoto Ikemiya, Tetsuya Ukon, Noritaka Kamei, Kazuma Yokohara

Patent number: 10034484Abstract: An oxygen concentration in the interior of a container is detected by an oxygen concentration detection sensor. If the oxygen concentration detected by the oxygen concentration detection sensor is higher than that of a gas mixture, the container is supplied with the gas mixture having an oxygen concentration lower than that of the outside air and higher than a target concentration. The oxygen concentration in the interior of the container is reduced to the vicinity of the oxygen concentration of the gas mixture by supplying the interior of the container with the gas mixture, and then is further reduced to the target concentration by respiration of plants. This appropriately controls the oxygen concentration in the interior of the container, and reduces a decrease in the degree of freshness of the plants.Type: GrantFiled: October 3, 2014Date of Patent: July 31, 2018Assignee: DAIKIN INDUSTRIES, LTD.Inventors: Naohiro Tanaka, Atsushi Ozato, Makoto Ikemiya, Tetsuya Ukon

Patent number: 9157422Abstract: A reciprocating pump includes a motor having a motor shaft, four cylinders, four pistons disposed in the cylinders and reciprocated by the motor shaft, a casing accommodating the motor shaft, and eight ducts. The four cylinders are disposed at positions offset 90 degrees from each other about the motor shaft. Cylinder shaft directions are perpendicular to a motor shaft direction. The eight ducts include four intake ducts and four exhaust ducts. Gas is introduced into the cylinders through the intake ducts and discharged from the cylinders through the exhaust ducts. The eight ducts are disposed in a region surrounded by the cylinders when viewed along the motor shaft direction. The eight ducts are arranged in four pairs with each pair disposed between adjacent cylinders about the motor shaft. The four pairs of ducts disposed between the adjacent cylinders extend along the motor shaft direction.Type: GrantFiled: September 7, 2012Date of Patent: October 13, 2015Assignee: Daikin Industries, Ltd.Inventors: Keita Kondou, Tetsuya Ukon, Munehiro Okamura

Publication number: 20140326122Abstract: A cutter prevents movement of a harness being cut. The cutter includes: a first cylindrical member and a second cylindrical member whose axial ends face each other, with a predetermined distance therebetween, and sandwich the harness in the axial direction; and a blade accommodated in the first cylindrical member to be slidable in the axial direction and including a cutting portion on a front side and a pusher on a back side. The first cylindrical member includes a back side tapered portion and a front side tapered portion at which an inner diameter of the first cylindrical member on an inner surface where the pusher slides is gradually reduced from a back side to a front side.Type: ApplicationFiled: November 28, 2012Publication date: November 6, 2014Applicant: Daikin Industries, Ltd.Inventors: Tetsuya Ukon, Teruaki Tsuchiya, Futoshi Okugawa

Patent number: 8653386Abstract: A blade (11), which includes a cutting portion (21) and an insulating portion (22), is used as a blade (11) of a cutting apparatus (10). The cutting portion (21) is made of a metal, and has a blade portion. The insulating portion (22) is formed by an insulating member, and forms a part that adjoins the blade portion in a direction opposite to an advance direction of the blade (11). The cutting apparatus (10) is configured so that, when cutting a current-carrying member (15), the blade (11) advances until the insulating portion (22) contacts cut faces of the current-carrying member (15) after the cutting portion (21) cuts the current-carrying member (15).Type: GrantFiled: September 3, 2008Date of Patent: February 18, 2014Assignee: Daikin Industries, Ltd.Inventors: Tetsuya Ukon, Teruaki Tsuchiya, Futoshi Okugawa
