Patent number: 8499541Abstract: A two-shaft gas turbine is capable of starting premixed combustion without extinguishing a flame. The two-shaft gas turbine includes a combustor and a gas generator controller. The combustor has a premix burner that includes combustion regions in which premixed combustion is to be carried out individually. The gas generator controller controls the combustor. In a method for starting the premixed combustion in the combustor, the gas generator controller selects at least one of the combustion regions in which the premixed combustion is to be carried out, on the basis of a fuel-air ratio, and starts premix combustion in the selected combustion region or separately in each of the selected combustion regions. Further, as the fuel-air ratio is increased, the controller increases the number of the selected region in which the premixed combustion is carried out.Type: GrantFiled: March 22, 2011Date of Patent: August 6, 2013Assignee: Hitachi, Ltd.Inventors: Ryo Kawai, Hidetaro Murata, Takeo Saito, Nobuaki Kizuka, Kenji Nanataki

Patent number: 8041591Abstract: A format conversion decision definition generating unit 104 stores information whether or not a response message format from a service unit 134 may be utilized in all later service callings of a business process without format conversion in a repository 121 as format conversion decision information 127, by referring to business process definition information 105 and adapter definition information 106. Then, when a business process operation control unit 132 executes the business process, an adapter operation control unit 133 refers to the format conversion decision information 127 about a target service 134 at the time, and skips the format conversion when information indicating that the format conversion is unnecessary is stored in the format conversion decision information 127.Type: GrantFiled: June 22, 2007Date of Patent: October 18, 2011Assignee: Hitachi, Ltd.Inventors: Ryo Kawai, Jun Yoshida, Mitsunobu Tasaka, Atsushi Hatakeyama

Patent number: 6437424Abstract: A barrier film of a SiON film is formed below an interlayer insulating film which is a single layer film or laminated film of an TEOS film or SOG film covering a floating gate 4 and control gate 6. The SiON film which is good in moisture blocking but poor in coverage is covered with another TEOS film which is better in coverage than the SiON film, thereby improving the barrier property of the barrier film. Such a configuration prevents moisture or H atoms contained in the TEOS film or SOG film from being diffused and trapped by the tunneling oxide film 3, thereby improving the trap-up rate and hence endurance characteristic and extending the operation life of a memory cell.Type: GrantFiled: February 16, 2000Date of Patent: August 20, 2002Assignee: Sanyo Electric Co., Ltd.Inventors: Takashi Noma, Masaji Hara, Kimihide Saito, Ryo Kawai, Yoichi Kanuma, Kazuo Okada
