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: 11938728Abstract: A liquid ejecting head includes: head chips including a first-head-chip and a second-head-chip; a holder holding the head chips; and a heater along a direction parallel to a nozzle surface. The first-head-chip and the second-head-chip are disposed to be offset from each other in both a first-direction and a second-direction parallel to the nozzle surface and intersecting with each other. When a first-side is one of the four sides of a virtual rectangle circumscribing the aggregate of the head chips and a second-side and a third-side are coupled to both ends of the first-side, the first-head-chip is in contact with the first-side and the third-side and the second-head chip is in contact with the second-side. The heater overlaps the head chips. A first-region surrounded by the first-side, the second-side, the first-head-chip, and the second-head-chip includes a first-outside-part positioned outside the outer edge of the heater.Type: GrantFiled: March 23, 2022Date of Patent: March 26, 2024Assignee: SEIKO EPSON CORPORATIONInventors: Takahiro Kanegae, Katsuhiro Okubo, Kentaro Murakami, Shingo Tomimatsu, Hiroki Kobayashi, Haruhisa Uezawa

Patent number: 11713826Abstract: A control valve includes: a second inner circumferential portion capable of holding a first spring, in a first communication passage provided at a first discharge opening of a housing; and a recessed portion recessed in a radial direction, at a position that is a part of a region in a circumferential direction of the second circumferential portion and overlaps a second communication passage opening in a biasing direction of the first spring. Therefore, when inserting the first spring into the first communication passage, it is possible to hold the first spring with the inner circumferential surface of the second inner circumferential portion. Consequently, the first spring is appropriately mounted in the second circumferential portion, thereby preventing a mounting defect of the first spring.Type: GrantFiled: September 3, 2020Date of Patent: August 1, 2023Assignee: HITACHI ASTEMO, LTD.Inventor: Shingo Murakami
