Patent number: 7472651Abstract: In a vessel (2) to which waste liquid (11) which contains ink pigment, water and cleaning liquid used in a printer is supplied, a metal electrode plate (30a, 30b) which allows the waste liquid (11) to flow therethrough is disposed to partition the inside of the vessel (2) into a first region (a) and a second region (b). A high voltage from a high-voltage power supply (7) is applied to the metal electrode plate (30a, 30b) while a grounding electrode (20) is connected to the first chamber (a) to generate an electrostatic field between the metal electrode plate (30a, 30b) and the grounding electrode (20) so that the water and the ink pigment are electrostatically agglomerated from the waste liquid (11) making use of electrophoresis of the ink pigment by the electrostatic field thereby to separate the waste liquid in the first region (a) into the cleaning liquid, water and ink pigment.Type: GrantFiled: March 19, 2003Date of Patent: January 6, 2009Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Hitoshi Isono, Shoichi Aoki, Junichi Ibushi, Masayuki Eda, Minoru Sueda, Masahiro Harada, Seiji Enma, Osamu Shinya, Shinji Ueoku

Publication number: 20070028786Abstract: A calender for a sheet of paper comprising a metal roll which is rotated by a first driving unit. The calender further comprises a rotatable cylindrical jacket, a pressurizing shoe, and a plurality of support members. The cylindrical jacket is disposed opposite the metal roll to form a calender nip so that the sheet of paper is continuously passed through the calender nip. The pressurizing shoe is provided within the jacket at the position of the calender nip and presses the interior surface of the jacket radially outward to pressurize the calender nip. The support members are disposed inside the jacket so that they are equally balanced in the peripheral direction of the jacket.Type: ApplicationFiled: October 10, 2006Publication date: February 8, 2007Applicant: MITSUBISHI HEAVY INDUSTRIES, LTD.Inventors: Setsuo Suzuki, Takeshi Matsuo, Junichi Ibushi, Hatsuo Mori, Fujio Shinoki

Publication number: 20050103460Abstract: In a twin wire former, white-water withdrawal means (20) for withdrawing white water (15) dewatered to the opposite side of a roll is arranged to the upstream side of a pressure element (30) to suppress the interference of the dewatered white water (15) with the pressure element (30). This renders it possible to prevent damage to the pressure element (30) that is caused by a collision with white water (15) during dewatering and to manufacture defect-free paper that has even dispersion of fibers.Type: ApplicationFiled: February 10, 2003Publication date: May 19, 2005Inventors: Kazuhiko Masuda, Hiroshi Iwata, Masanobu Matsumoto, Junichi Ibushi

Patent number: 6873264Abstract: A rotational phase difference detecting system, a method that is capable of very accurately detecting a rotational phase difference between a plurality of rotating bodies, a machine operating-state monitoring system, and a method employing the rotational phase difference detecting system. The detecting system has a first rotating body with a first mark, a second rotating body with a second mark, a mark sensor for detecting the first mark, a first camera for imaging the second mark when the mark sensor detects the first mark, and a display section for displaying the second mark imaged by the first camera. The rotational phase difference is detected from a position of an image of the second mark displayed on the display section and is thus detected very accurately with a simple construction comprising the mark sensor, the first camera, and the display section.Type: GrantFiled: April 24, 2001Date of Patent: March 29, 2005Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Atsushi Ikeda, Hiroshi Yamashita, Masahiro Yamaguchi, Junichi Ibushi

Patent number: 4716687Abstract: An improved method and apparatus for grinding a rotary body, in which a rotatably supported grindstone is positioned in such manner that an extension of a rotary axis of the grindstone does not intersect a rotary axis of the rotary body and the rotary axis of the grindstone is inclined with respect to a plane perpendicular to the rotary axis of the rotary body to be ground. The rotary body to be ground is rotatably driven, and the grindstone is pressed against the outer circumferential surface of the rotary body to be ground in order that the outer circumferential surface of the rotary body to be ground can be ground by a relative slip produced at a contact point between the outer circumferential surface of the rotary body to be ground and the grindstone.Type: GrantFiled: February 3, 1986Date of Patent: January 5, 1988Assignee: Mitsubishi Jukogyo Kabushiki KaishaInventors: Hidehiko Tsukamoto, Kanji Hayashi, Tsunetaka Sumomogi, Masashi Oya, Junichi Ibushi, Katsuaki Takasaki, Masao Arikawa, Tateo Tanimoto, Kunio Yamamoto, Kanehisa Miyaguchi, Yoshiki Mito, Tamenari Doho

Patent number: 4671017Abstract: A method and apparatus for grinding a roll in a rolling mill on an on-line grinding basis, are improved in that a freely rotatable grinding body such and is a grindstone is pressed against a surface of the roll to be ground as directed in the direction making a predetermined angle with respect to the axis of the roll. The roll is rotated so that the surface of the roll may be ground by a relative slip between the grinding body and the roll caused by their different circumferential velocities.Type: GrantFiled: January 9, 1986Date of Patent: June 9, 1987Assignee: Mitsubishi Jukogyo Kabushiki KaishaInventors: Kazuo Ideue, Masashi Oya, Kanji Hayashi, Tsuneo Egawa, Hiroaki Shimazutsu, Junichi Ibushi, Kunio Yamamoto, Kanehisa Miyaguchi, Tamenari Doho
