Patent number: 6809278Abstract: The electronic equipment makes manipulation surface of a pushbutton accurately project through a button hole formed in a face panel and can prevent play of the pushbutton even when positioning accuracy of the button hole is poor. The electronic equipment is configured such that an outer button and an inner button are mounted in a state that the buttons are movable relative to each other and engaging projections formed on the outer button are respectively positioned to engaging holes formed in the face panel. Due to such a constitution, even when an axis of the button hole of the face panel and an axis of a guide portion of a chassis are displaced form each other, it is possible to make a manipulation surface of the outer button accurately project through the button hole and, at the same time, it is possible to prevent play of the outer button.Type: GrantFiled: March 18, 2004Date of Patent: October 26, 2004Assignee: Matsushita Electric Industrial Co., Ltd.Inventor: Yasuhiro Tsubaki

Patent number: 6614000Abstract: The present invention is an organic halogen compound decomposition device which utilizes a plasma, wherein a stable and reliable ignition at operation commencement is possible, and where following ignition, a good plasma form can be maintained and stable operation is possible. The organic halogen compound decomposition device is equipped with a cylindrical waveguide 7 made up of an outer conductor 8 and an inner conductor 9, and a dual construction discharge tube 5 made up of an inner tube 11 and an outer tube 12 which is provided inside the cylindrical waveguide 7 and on an identical axis. Furthermore, a probe antenna 9a formed from an extension of the inner conductor 9 is positioned so as to encircle the discharge tube 5, and the tip of the inner tube 11 is positioned further inwards than the tip of the probe antenna 9a.Type: GrantFiled: December 12, 2000Date of Patent: September 2, 2003Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Masahiro Bessho, Toshio Hattori, Yasuhiro Tsubaki

Patent number: 6605750Abstract: A product gas generated through the decomposition reaction of organohalogen compounds and steam is neutralized with an alkali solution and is left to stand for a predetermined period of time, while a neutralization product generated in this neutralization reaction is caused to precipitate in the alkali solution and is then removed. In order to remove the neutralization product completely, a takeout tube 71 is disposed to plunge into a waste gas processing tank 41 and a disk-shaped plate 71a is fastened at the distal end of the takeout tube 71 in parallel to the bottom surface of the waste gas processing tank 41, while the takeout tube 71 opens in the lower surface of the plate 71a at the center thereof. Thus the solid-liquid separation efficiency of the neutralization product and the alkali solution is improved and the quantity of alkali solution remaining in the neutralization product that is disposed of as waste is decreased.Type: GrantFiled: December 8, 2000Date of Patent: August 12, 2003Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Masahiro Bessho, Toshio Hattori, Yasuhiro Tsubaki, Takayoshi Hamada

Patent number: 5586456Abstract: In a dry cleaner, after clothes 2 is washed, the washing solvent contained in the washed clothes 2 is dissolved into a liquid perfluorocarbon 4a being heated at its boiling point or thereabout in order to remove the washing solvent. Thereafter, drying of the clothes 2 is performed by mainly aiming to evaporate the liquid perfluorocarbon 4a contained in the clothes 2. Since the drying is targeted on the liquid perfluorocarbon, the time required for drying clothes can markedly reduced.Type: GrantFiled: September 19, 1995Date of Patent: December 24, 1996Assignee: Mitsubishi Jukogyo Kabushiki KaishaInventors: Hiroyuki Takagawa, Yasuhiro Tsubaki, Yoshio Miyairi, Toshio Hattori, Haruo Hagiwara

Patent number: 5195252Abstract: The present invention is directed to a technique which comprises the steps of stopping the rotation of a treating drum in a deodorizing step, introducing the outside air into a treating tank through an upper opening provided in the upper portion of the treating tank or the upper portion of a recovery air duct, simultaneously exhausting a solvent gas from the treating tank through a lower opening provided in the lower portion of the treating tank or a button trap portion so slowly as not to agitate the solvent gas in the treating tank by an exhaust means connected to a solvent recovery device in the condition that the treating drum is stopped, in order to replace the solvent gas in the treating tank with the outside air, and reusing the solvent gas through the solvent recovery device once or several times. In addition, the present invention is further directed to an improvement of the above-mentioned technique.Type: GrantFiled: August 16, 1991Date of Patent: March 23, 1993Assignee: Mitsubishi Jukogyo Kabushiki KaishaInventors: Kiyomi Yamada, Haruo Hagiwara, Nobuharu Takagi, Hideo Tsukamoto, Yasuhiro Tsubaki, Toshio Hattori
