Patent number: 9322388Abstract: Provided is a wave-power generator capable of adjusting a natural period (natural frequency) in response to a changing wave period. The wave-power generator includes a weight that is installed in a floating body via a spring and that linearly reciprocates in response to a fluctuation of a water surface and a generator that generates power by being driven based on the linear reciprocating motion of the weight. An additional-mass body for adding a mass to the mass of the weight is further included.Type: GrantFiled: March 15, 2012Date of Patent: April 26, 2016Assignees: MITSUBISHI HEAVY INDUSTRIES, CO., LTD., THE UNIVERSITY OF TOKYOInventors: Kentaro Hayashi, Takeshi Yasunaga, Shunichi Ikesue, Makoto Ohta, Masami Miura, Yasuyoshi Takamoto, Yoshinori Kobayashi, Hideaki Hashimoto, Shozo Kaneko, Akira Hashimoto

Patent number: 8671641Abstract: Providing a half precast slab even in a case where the thickness of the slab in the site condition is too thick to apply conventional precast construction techniques. A half precast slab including a plurality of floor concrete form members and, each floor concrete form member being provided with: a bottom slab of a long length, in response to the floor concrete form member; a pair of side walls installed upright along each longitudinal edge of the bottom slab, in response to the floor concrete form member; thereby, each floor concrete form member is arranged so as to be parallel to each other and be tightly connected to the adjacent floor concrete form member, along the direction perpendicular to the longitudinal direction of each floor concrete form member; the height of the side walls other than the side walls on the most outer edge sides of the whole floor concrete form members is set at a common height that is smaller than the height of the side walls on the most outer edge sides.Type: GrantFiled: February 15, 2013Date of Patent: March 18, 2014Assignee: Mitsubishi Heavy Industries, Co., Ltd.Inventors: Takeo Takakura, Satoru Tanaka, Yumi Tanaka, Toshiaki Kato, Naoyuki Kita, Nobuyuki Kawabata

Patent number: 8636615Abstract: A planetary gear train is provided with: a planetary gear; a planetary pin for supporting the planetary gear; a carrier for supporting the planetary pin; and a housing for accommodating at least a portion of the carrier, the planetary gear and the planetary pin. The planetary gear is rotatable with respect to the planetary pin by a bearing. An oiling flow path for supplying lubricant oil to the bearing is formed inside the carrier. The carrier receives the lubricant oil into the oiling flow path from an oiling member stationarily fixed to the housing. The inlet for receiving the lubricant oil into the oiling flow path of the carrier from the oiling member is positioned inside the housing.Type: GrantFiled: February 27, 2013Date of Patent: January 28, 2014Assignees: Mitsubishi Heavy Industries, Co., Ltd, Ishibashi Manufacturing Co., Ltd.Inventors: Kazutaka Suzuki, Kazufumi Takayanagi, Takafumi Yoshida, Tadasuke Nishioka, Toshiharu Goya, Motohisa Uesato, Masahiro Kusaka

Patent number: 6668538Abstract: A combined cycle system includes a gas turbine (8) having a generator (1), a compressor (2), a combustor (3), a blade cooling air cooler (4), a fan (5), and a turbine (6); a steam turbine (29) having a high pressure turbine (21), an intermediate pressure turbine (22), and a low pressure turbine (23); and a waste heat recovery boiler (9). Saturated water from a high pressure pump (27) is partially led into a heat exchanger (110) for cooling steam to be supplied into a moving blade (52) and a stationary blade (53). Also, outlet steam from the high pressure turbine (21) is led into the moving blade (52), the stationary blade (53), and the combustor transition piece (54) for cooling thereof, and the steam is then supplied to an inlet of the intermediate pressure turbine (22). Further, the outlet steam from the high pressure turbine (21) is led into the turbine (6) for cooling blades thereof.Type: GrantFiled: October 24, 2002Date of Patent: December 30, 2003Assignee: Mitsubishi Heavy Industries Co., Ltd.Inventors: Hideaki Sugishita, Sunao Aoki, Kazuo Uematsu, Keizo Tsukagoshi
