Patent number: 11959147Abstract: A top-blowing lance nozzle is configured to freely switch an adequate expansion condition so as to control an oxygen-blowing amount and a jetting velocity independently of each other without requiring a plurality of lance nozzles or a mechanically movable part. A lance nozzle is configured to blow refining oxygen to molten iron charged in a reaction vessel while a gas is blown from a top-blowing lance to the molten iron. One or more blowing holes for blowing a working gas are on an inner wall side surface of the nozzle, at a site where the lance nozzle has a minimum cross-sectional area in a nozzle axis direction or at a neighboring site of the site.Type: GrantFiled: April 2, 2020Date of Patent: April 16, 2024Assignee: JFE STEEL CORPORATIONInventors: Yumi Murakami, Nobuhiko Oda, Yusuke Fujii, Goro Okuyama, Shota Amano, Shinji Koseki, Shingo Sato, Yukio Takahashi, Ryo Kawabata, Naoki Kikuchi, Atsuo Yuasa

Patent number: 6572941Abstract: A touch panel is constructed of a top sheet member having a resistive membrane on its inner surface and a base sheet member having a resistive membrane on its inner surface, the top and base sheet members facing each other with dot spacers being located in between. The top sheet member is formed by laminating a PET film, a polarizing film, a ¼&lgr; retardation film, and a light isotropic film in this order from its outer surface. The PET film has a thermal expansion coefficient lower than the other films underneath, such as the polarizing film. Accordingly, the PET film serves to keep the other films of the top sheet member from bulging outward when the temperature rises.Type: GrantFiled: May 18, 2000Date of Patent: June 3, 2003Assignee: Gunze LimitedInventors: Yukio Murakami, Shunsuke Hirano

Patent number: 6570707Abstract: A touch panel is constructed of a top sheet member having a resistive membrane on its inner surface and a base sheet member having a resistive membrane on its inner surface, the top and base sheet members facing each other with dot spacers being located in between. The top sheet member is formed by laminating a bulge-resistant film, a polarizing plate, a quarter wavelength plate, and a light isotropic film in this order from above. The base sheet member is constructed of a glass sheet and a reinforcement film whose thermal linear expansion coefficient is almost the same as the thermal linear expansion coefficient of the polarizing plate or the quarter wavelength plate included in the top sheet member, the reinforcement film being adhered to the lower surface of the glass sheet.Type: GrantFiled: November 8, 2000Date of Patent: May 27, 2003Assignee: Gunze LimitedInventors: Yukio Murakami, Shunsuke Hirano

Patent number: 6559834Abstract: A touch panel is constructed of a top sheet member having a resistive membrane on its inner surface and a base sheet member having a resistive membrane on its inner surface, the top and base sheet members facing each other with dot spacers being located in between. The top sheet member is formed by laminating a bulge-resistant film, a polarizing plate, a quarter wavelength plate, and a light isotropic film in this order from above. A PET film which is not heat-treated so as to have a higher thermal contraction rate than the other members of the top sheet member underneath such as the polarizing plate, is used as the bulge-resistant film. Since the bulge-resistant film contracts more than the polarizing plate under a high ambient temperature, after the ambient temperature returns to normal, the bulge-resistant film does not become slack against the polarizing plate. Accordingly, the top sheet member can be kept from bulging outward.Type: GrantFiled: September 1, 2000Date of Patent: May 6, 2003Assignees: Gunze Limited, Sumitomo Chemical Company, Ltd.Inventors: Yukio Murakami, Shunsuke Hirano, Keiichi Minakuchi

Patent number: 4932901Abstract: A single filament type wedge-base lamp has projections on opposite sides at opposite end portions of a flat base of the lamp, and the corresponding socket has a recess with clearance grooves corresponding in position to the projections. The socket for a double filament type wedge-base lamp has a recess without clearance grooves so that the single filament type wedge-base lamp, which has the projections thereon, is prevented from erroneously being inserted into the double-filament type lamp socket since the projections will interfere with the recess walls of the double-filament type lamp socket. If a double filament type lamp is inserted into the socket for a single filament type lamp, either one of the two filaments thereof will operate without posing a problem.Type: GrantFiled: August 29, 1988Date of Patent: June 12, 1990Assignee: Tokyo Electric Co., Ltd.Inventors: Yukio Murakami, Akira Toyoshima
