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: 11940458Abstract: A measurement tool includes: a measurement tool body including a sample collection unit for collecting a liquid sample by a capillary phenomenon, and a liquid feed channel; and a lid body attachable to and detachable from the measurement tool body. The liquid feed channel includes an upstream side channel and a downstream side channel. A space is defined, into which an upstream side end of the sample collection unit and a downstream side end of the upstream side channel open, when the lid body is attached to the measurement tool body. The downstream side channel is connected to a downstream side end of the sample collection unit. The space is open when the lid body is separated from the measurement tool body, and the space is closed and the upstream side channel and the sample collection unit are connected when the lid body is attached to the measurement tool body.Type: GrantFiled: November 21, 2019Date of Patent: March 26, 2024Assignee: SEKISUI CHEMICAL CO., LTD.Inventors: Tsutomu Nakamura, Kazuhiko Imamura, Nobuhiko Inui, Ryousuke Takahashi

Patent number: 8334344Abstract: The sliding material is obtainable by extrusion of a raw material containing an olefin-based polymer and a silicone compound as the essential components. A part of the olefin-based polymer forms a crosslinked material in the sliding material. The crosslinked material forms domains to disperse in the sliding material so as to prevent uneven distribution of the silicone compound in the extrusion direction. The residual fraction of hot xylene reflux of the sliding material is in a range from 33 to 75% by weight based on the total weight of the sliding material, and the content of the silicone compound based on the total weight of the sliding material is in a range from 5 to 35% by weight.Type: GrantFiled: May 13, 2009Date of Patent: December 18, 2012Assignee: Shin-Etsu Polymer Co., Ltd.Inventors: Masayuki Honda, Nobuyasu Noda, Hajime Tsujihana, Fukuji Watanobe, Nobuhiko Takahashi, Tsuneo Usuda

Patent number: 6036251Abstract: A car trim including a plurality of ribs formed integrally and arranged vertically at a predetermined interval on a predetermined site of the rear face 1a of trim main body 1 for absorbing energy of collision, each rib being formed in a rectangular tube, each rib side wall 4a being tapared with thinning toward its distal end, and a rigidity changing portion P being disposed by integrally forming an auxiliary rib piece 5 on the rib side wall 4a for introducing buckling transformation of the rib 4 at a predetemined position in the rib side wall 4a. The rib also includes a first energy absorbing portion 5 and a second energy absorbing portion 6 formed in such a multi-stepped manner that the number of rib walls in the former step is different from that number in the latter step.Type: GrantFiled: June 14, 1999Date of Patent: March 14, 2000Assignees: Kasai Kogyo Kabushiki Kaisha, Nissan Motor Co., Ltd.Inventors: Fumio Yagishita, Kazushi Yasue, Nobuhiko Takahashi, Akira Kawai

Patent number: 5730783Abstract: A process for concentrating ozone, which includes switching a plurality of adsorption columns each packed with an adsorbent capable of preferentially adsorbing ozone thereon sequentially to an adsorption step where the adsorbent is maintained at a low temperature to adsorb ozone thereon; a desorption step where the adsorbent is heated to desorb ozone therefrom, and a scavenger gas is introduced in a substantially fixed amount into the adsorption column to discharge the thus desorbed ozone being carried on the scavenger gas; and a cooling step where the adsorbent having completed the desorption step is cooled to the same low temperature level as in the adsorption step. Heating of the adsorbent in the desorption step is carried out depending on the time elapsed after desorption is started or on the ozone concentration of the gas discharged from the adsorption column performing the desorption step. A gas having a predetermined pressure is employed as the scavenger gas in the desorption step.Type: GrantFiled: October 4, 1996Date of Patent: March 24, 1998Assignee: Nippon Sanso CorporationInventors: Hiroshi Sanui, Nobuhiko Takahashi, Shigeyuki Yamamoto

Patent number: 5584525Abstract: An automotive seat comprises a seat slide device mounted on a vehicle floor between a side sill and a tunnel portion. The seat slide device includes a movable rail which moves in a given direction along the side sill. A seat cushion frame is mounted on the movable rail to move therewith, and a seatback frame is pivotally connected to the seat cushion frame through paired pivot devices. A reinforcing structure is incorporated with at least one of the seat cushion frame and the paired pivot devices to provide the seat with a tough resistance against a side vehicle collision. The reinforcing structure includes a reinforcing beam secured to two mounting brackets secured by respective flange plates to the side sill and the tunnel portion. In another aspect of the invention, another bracket is secure to the top of the tunnel portion and also secured to the corresponding flange plate of the reinforcing beam.Type: GrantFiled: March 2, 1994Date of Patent: December 17, 1996Assignees: Nissan Motor Co., Ltd., Ikeda Bussan Co., Ltd.Inventors: Nobuyuki Nakano, Nobuhiko Takahashi

Patent number: 5507554Abstract: In a motor vehicle, there are arranged abreast first and second seats. Each seat includes a seat cushion, a seatback pivotally connected to the seat cushion, and a power reclining device for pivoting the seatback to a desired angular position. A load transmitting center structure is mounted on the vehicle floor between the first and second seats. A manual switch is used which, when operated, pivots the seatback of the second seat to a desired angular position. At least the second seat has a reinforcing structure installed therein. The reinforcing structure exhibits the maximum performance in cooperation with the load transmitting center structure when the seatback of the second seat is within a given angular range.Type: GrantFiled: October 14, 1994Date of Patent: April 16, 1996Assignee: Ikeda Bussan Co., Ltd.Inventors: Nobuyuki Nakano, Nobuhiko Takahashi
