Patent number: 11913277Abstract: A method for manufacturing a glass panel unit includes an assembling step, a bonding step, a gas exhausting step, a sealing step, and an activating step. The bonding step includes melting a peripheral wall in a baking furnace at a first predetermined temperature to hermetically bond a first glass pane and a second glass pane together with the peripheral wall thus melted. The gas exhausting step includes exhausting a gas from an internal space through an exhaust port in the baking furnace to turn the internal space into a vacuum space. The sealing step includes locally heating to a temperature higher than a second predetermined temperature, and thereby melting, either a port sealing material or an exhaust pipe to seal the exhaust port and thereby obtain a work in progress. The activating step includes activating a gas adsorbent after the sealing step to obtain a glass panel unit.Type: GrantFiled: June 19, 2019Date of Patent: February 27, 2024Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Hiroyuki Abe, Eiichi Uriu, Kazuya Hasegawa, Tasuku Ishibashi, Masataka Nonaka, Takeshi Shimizu, Haruhiko Ishikawa

Patent number: 7976608Abstract: In a solder paste which is a mixture of a flux and low melting point metal particles, low melting point metal fine particles manufactured by a conventional method or apparatus therefor include particles having widely varying particle diameters. Accordingly, the solder paste could not completely fill the minute holes in a mask for application to minute solder portions by printing, or mask removability was poor. According to the present invention, a mixture of a heat resistant continuous phase liquid and coarse metal particles in molten state is passed through a porous membrane to form the coarse low melting point metal particles into fine particles with a predetermined diameter. An apparatus according to the present invention comprise a porous membrane between a heating and dispersing mechanism and a cooling mechanism, and a pressure vessel connected to the heating and dispersing mechanism for applying a high pressure to the heating and dispersing mechanism.Type: GrantFiled: March 9, 2005Date of Patent: July 12, 2011Assignees: Senju Metal Industry Co., Ltd., Miyazaki PrefectureInventors: Kiyoshi Torigoe, Masataka Shimizu, Kenji Yamamoto, Mitsuhiro Mizozoe, Hoshiro Takahashi, Tomohide Suzuki, Motohiro Murase

Patent number: 7938883Abstract: A method of making metallic iron in which a compact, containing iron oxide such as iron ore or the like and a carbonaceous reductant such as coal or the like, is used as material, and the iron oxide is reduced through the application of heat, thereby making metallic iron. In the course of this reduction, a shell composed of metallic iron is generated and grown on the surface of the compact, and slag aggregates inside the shell. This reduction continues until substantially no iron oxide is present within the metallic iron shell. Subsequently, heating is further performed to melt the metallic iron and slag. Molten metallic iron and molten slag are separated one from the other, thereby obtaining metallic iron with a relatively high metallization ratio.Type: GrantFiled: September 14, 2007Date of Patent: May 10, 2011Assignee: Kabushiki Kaisha Kobe Seiko ShoInventors: Takuya Negami, Kazuo Kunii, Shinichi Inaba, Masataka Shimizu, Isao Kobayashi, Yoshimichi Takenaka, Toshihide Matsumura, Akira Uragami, Takashi Kujirai, Osamu Tsuchiya, Kimio Sugiyama, Shuzo Ito, Shoichi Kikuchi
