Patent number: 7755798Abstract: The invention relates to picture color tone control for a printing press. A target color mixture halftone density for each ink supplying unit width when a printing picture is divided with an ink supplying unit width of ink supplying apparatus 6, 7 is set, and an actual color mixture halftone density for each ink supplying unit width of an actually printed sheet obtained by printing is measured using an IRGB densitometer 1. The color mixture halftone densities are individually converted into tone values. A changing ratio for the converted target tone values is set suitably and is reflected on the target tone values and then converted into a monochromatic halftone density. Then, a solid density difference corresponding to a difference between the target monochromatic halftone density and an actual monochromatic halftone density is determined, and the ink supplying amount is adjusted for each ink supplying unit width in response to the solid density difference.Type: GrantFiled: November 11, 2005Date of Patent: July 13, 2010Assignee: Mitsubishi Heavy Industries, LtdInventors: Ikuo Ozaki, Syuuchi Takemoto, Norifumi Tasaka

Patent number: 7692322Abstract: A wind turbine generator, an active damping method thereof, and a windmill tower in which vibrations of the wind turbine generator itself or the windmill tower can be reduced at low cost are provided. The acceleration due to vibrations of a nacelle (13) is detected with an accelerometer (17) attached to the nacelle (13). In an active damping unit (20), a pitch angle of windmill blades (12) for generating a thrust on the windmill blades (12) so as to cancel out the vibrations of the nacelle (13) is calculated on the basis of the acceleration, and the pitch angle is output as a blade-pitch-angle command ??* for damping. On the other hand, in a pitch-angle control unit (30), a pitch angle of the windmill blades (12) for controlling the output to be a predetermined value is calculated, and the pitch angle is output as a blade-pitch-angle command ?* for output control. The blade-pitch-angle command ??* for damping is combined with the blade-pitch-angle command ?* for output control using a subtracter (40).Type: GrantFiled: November 12, 2004Date of Patent: April 6, 2010Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Tsuyoshi Wakasa, Kazunari Ide, Yoshiyuki Hayashi, Masaaki Shibata

Patent number: 7482724Abstract: The present invention provides a technique for enabling permanent magnets constituting the field magnet system of an IPM electric rotating machine to be embedded in a rotor core in a shallower depth. The IPM electric rotating machine is composed of a stator and a rotor. The rotor includes a rotor core and permanent magnets constituting the field magnet system. The rotor core has a side face opposed to the stator, and the permanent magnets are shallowly embedded so that the distance between the pole face thereof and the rotor side face is reduced. Furthermore, two adjacent permanent magnets are intensively spaced so that the following formula holds: 0.3<(Lq?Ld)/Ld, where Lq is the q-axis inductance of the rotor, and Ld is the d-axis inductance thereof.Type: GrantFiled: February 3, 2005Date of Patent: January 27, 2009Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Kenji Fujiwara, Takatoshi Kogure, Akira Nishio, Tutomu Baba
