Patent number: 5624231Abstract: A turbine blade performs internal cooling by a cooling gas flowing through internal cooling flow passages and FCFC cooling by a cooling gas jetted out through film holes arranged on the substantially whole area of the blade surface. The film holes are arranged in rows extending in the span direction at predetermined pitches in the chord direction. The dimensions of the elements of the turbine blade are determined by a mathematical formula 5.ltoreq.L/N.multidot.D.ltoreq.50, where L is the length of any interval of the surface of the cooled turbine blade, N is the number of rows of the film holes in the interval and D is an average diameter of the film holes in the interval. With this arrangement, the maximum cooling efficiency at a small amount of cooling gas flow is attained, and both the quantity of heat per unit area of the blade surface transmitted from the main flow gas to the blade surface and the thermal stresses are reduced.Type: GrantFiled: December 28, 1994Date of Patent: April 29, 1997Assignee: Kabushiki Kaisha ToshibaInventors: Fumio Ohtomo, Yoshitaka Fukuyama, Yuji Nakata, Asako Inomata, Hisashi Matsuda, Shoko Ito

Patent number: 5538394Abstract: A cooling flow passage assembly consisting of pressure side cooling flow passages extending in a span direction and suction side cooling flow passages extending in the span direction and serially connected to the pressure side cooling flow passages is formed in a turbine blade. A cooling medium flows through the pressure side cooling flow passages in the direction toward the tip portion and through the suction side cooling flow passages in the direction toward the root. Cooling effect is improved by a Coriolis force. The number of the suction side cooling flow passages is larger than the number of the pressure side cooling flow passages. At least one of the suction side cooling flow passages forms at least one most downstream cooling flow passage. The cooling medium flows through the most downstream cooling flow passage and is exhausted outside of the turbine blade through nozzles, whereby the flow of the cooling medium through the most downstream cooling flow passage is speeded up.Type: GrantFiled: December 28, 1994Date of Patent: July 23, 1996Assignee: Kabushiki Kaisha ToshibaInventors: Asako Inomata, Hisashi Matsuda, Yoshitaka Fukuyama, Fumio Ohtomo, Yuji Nakata, Hideo Nomoto

Patent number: 4952803Abstract: A double focusing mass spectrometer is used as the second mass analyzer of a Mass Spectrometry/Mass Spectrometry Instrument comprising a uniform electric field and a magnetic sector. Fragment ions produced from precursor ions of a certain ionic species are introduced into a uniform electric field.

Patent number: 4866267Abstract: A double-focusing mass spectrometer comprising a Wien filter and a homogeneous magnetic field. Daughter ions produced from parent ions of a certain ionic species differ in mass but have velocities substantially equal to that of the parent ions. The Wien filter is set up such that the velocities of the daughter ions satisfy the Wien condition. Thus, the daughter ions originated from the specified parent ions pass through the filter and are dispersed according to mass by the homogeneous magnetic field and focused into a focal plane. A two-dimensional ion detector is disposed along this focal plane in order to simultaneously detect said daughter ions and to obtain a spectrum of the daughter ions.Type: GrantFiled: April 12, 1988Date of Patent: September 12, 1989Assignee: JEOL Ltd.Inventors: Hisashi Matsuda, Motohiro Naito

Patent number: 4418280Abstract: A double focusing mass spectrometer having a diverging electrostatic field, a converging electrostatic field and a converging magnetic field. The two electrostatic fields are connected with each other without substantial free space therebetween.
