Publication number: 20120148391Abstract: A centrifugal compressor is equipped with a resin housing, that is made in a manner such that compression efficiency is not lost and merits such as weight and cost reduction are not cancelled out. The turbo charger housing comprises a volute section, a channel formation section, and an impeller that is fixed in the center of the channel formation section to a rotating shaft. An annular shroud is disposed in a recess formed on the inner wall of the channel formation section. The annular shroud forms the outer walls of a channel and a diffuser for compressed gas. The edge of the annular shroud spaced from a partition wall, which forms a portion of a bearing housing. If the resin housing undergoes thermal deformation, the dimensions of a gap between the annular shroud and the curved profile of a blade is maintained.Type: ApplicationFiled: March 17, 2010Publication date: June 14, 2012Applicant: MITSUBISHI HEAVY INDUSTRIES, LTD.,Inventors: Seiichi Ibaraki, Isao Tomita, Yasuaki Jinnai, Takashi Mikogami, Masaki Tojo, Akio Kitada

Patent number: 7839069Abstract: The orientation of fluorescent lamps is detected in a manufacturing method for a direct backlight unit that alternates orientations of adjacent fluorescent lamps. In a preparation step of the manufacturing method for the backlight unit of the present invention, a plurality of fluorescent lamps are prepared. In each of the fluorescent lamps, a length (a1) from a first sealed portion of a glass bulb (26) to a non-phosphor layer (32) area is shorter than a length (a2) from a second sealed portion to a non-phosphor layer (32) area (a1<a2). In a detection step, the difference between the lengths is detected with use of a sensor. In an installation step, the fluorescent lamps are arranged with use of the detection results so that the first and second ends alternate on a same side of a housing.Type: GrantFiled: February 21, 2007Date of Patent: November 23, 2010Assignee: Panasonic CorporationInventors: Akiko Nakanishi, Taizou Ono, Hirofumi Yamashita, Kazuhiro Kumada, Haruo Yamazaki, Shinji Kihara, Akio Kitada, Masanobu Murakami, Tomokazu Matsuura, Hiroshi Sakurai, Makoto Yokozeki, Takashi Maniwa, Shigeru Ido

Publication number: 20090096958Abstract: A cold cathode fluorescent lamp includes a glass bulb (16), a protective film (22) formed on an inner face of the glass bulb, and a phosphor layer (24) that overlaps the protective film and that contains blue phosphor particles (26B), green phosphor particles (26) and red phosphor particles (26). The glass bulb has been formed from soda glass, and the blue phosphor particles have been coated with a metal oxide (30). Also, the protective film is made of silica (SiO2). Since the protective film has been provided in the fluorescent lamp and since the blue phosphor particles, which readily deteriorate, have been coated with the metal oxide, a good luminance maintenance rate is obtained. In addition, although the glass bulb of the fluorescent lamp is made of soda glass, since the protective film is made of silica, the fluorescent lamp obtains an initial luminance equivalent to the initial luminance of a fluorescent lamp whose glass bulb is made of borosilicate glass.Type: ApplicationFiled: March 23, 2007Publication date: April 16, 2009Inventors: Tomokazu Matsuura, Akiko Nakanishi, Hideki Wada, Akio Kitada, Masanobu Murakami, Hiroshi Sakurai, Takashi Maniwa, Kazuhiro Kumada, Shigeru Ido, Makoto Yokozeki, Nozomu Hashimoto

Patent number: 7223145Abstract: An object of the present invention is to provide, without increasing the costs or decreasing the quantity of light, a fluorescent lamp that is less likely to have the bridge and the constituent tubes damaged while being handled and has improved handleability, as well as to provide a manufacturing method therefor. It is arranged so that the distance between the first and second constituent tubes gradually becomes smaller from the base side of the lamp toward the turning portion side of the lamp where the discharge paths turn. It is arranged so that the value of D2/D1 is within a range of 0.05 to 0.70 inclusive, where D1 is the distance between the first and second constituent tubes being measured at the bridge connecting points on the base side, and D2 is the shortest distance between the first and second constituent tubes on the turning portion side.Type: GrantFiled: August 15, 2005Date of Patent: May 29, 2007Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Yusuke Okazaki, Nobutaka Ota, Toshiyuki Namura, Akio Kitada, Tadashi Shimizu
