Patent number: 11440448Abstract: There are improved a vibration absorption characteristic and an impact absorption characteristic. In a suspension mechanism 1 of the present invention, first and second dampers (150, 160) are suspended in parallel between an upper frame (120) and a lower frame (110) with mounting angles different from each other. For this reason, the smaller mounting angle the damper has, the smaller a vertical component of damping force becomes, and the damping force which acts on the upper frame (120) and the lower frame (110) which move up and down relatively is moderate in effectiveness as compared with a case of disposing all the dampers at the same mounting angle. Thus, a sense of incongruity in which strong damping force acts abruptly is suppressed and the vibration absorption characteristic and the impact absorption characteristic are improved, which leads to improvement in ride comfort.Type: GrantFiled: May 20, 2019Date of Patent: September 13, 2022Assignee: DELTA KOGYO CO., LTD.Inventors: Etsunori Fujita, Eiji Sugimoto, Yumi Ogura, Soichi Makita, Masahiro Mashino, Shigeyuki Kojima, Atsushi Nishida, Jun Fukuda, Ryuji Kuwano

Patent number: 10968974Abstract: A damper includes: a line-shaped member wound around an outer peripheral surface of a piston which makes a relative motion in a cylinder; and a viscous fluid made to adhere to the line-shaped member and exhibiting viscous damping force. The relative motion of the cylinder and the piston produces tension, and in the line-shaped member, as an amplitude is smaller, its contiguously wound portions each try to deform to twist along a circumferential direction of the line-shaped member itself, and as the amplitude is larger, the contiguously wound portions try to deform as a unit. When the amplitude is small, frictional resistance decreases, resulting in smooth motion of the piston, and appropriate damping force is obtained due to the viscous damping force of the viscous fluid. When the amplitude is large, as a result of the increased tendency that the contiguously wound portions of the line-shaped member try to deform as a unit, friction damping force acts relatively greatly.Type: GrantFiled: August 4, 2017Date of Patent: April 6, 2021Assignee: DELTA TOOLING CO., LTD.Inventors: Etsunori Fujita, Yumi Ogura, Ryuji Kuwano, Jiro Kondo, Jun Fukuda

Patent number: 10363839Abstract: A seat slide adjuster suited to weight-saving has a structure in which two rows of engaged portions are provided at a predetermined interval in a direction orthogonal to a longitudinal direction of a locking plate that constitutes a locking mechanism, and the engaged portions engage with locking tooth parts on both sides of a lower rail during locking. Force that works between the locking plate and the lower rail acts on the locking tooth parts on both sides in a well-balanced manner and is not biased to either side. As a result, the durability of the components thereof can be improved. In addition, because two rows of hole portions in the locking plate engage, rattling of the locking plate is not likely to occur.Type: GrantFiled: October 11, 2016Date of Patent: July 30, 2019Assignee: DELTA KOGYO CO., LTD.Inventors: Jun Fukuda, Katsuhiro Inoue

Patent number: 8395260Abstract: A semiconductor device and manufacturing method thereof improving moisture resistance of a FeRAM. After a probe test using a pad, a metal film is formed to cover the pad in an opening of a protective film and a region from the pad to an opening outer periphery of the protective film. On the metal film, a metal bump is formed. The metal film is formed to have a two-layer structure of the first and second metal films. Materials of the lower and upper layers are selected mainly in consideration of adhesion to the protective film and adhesion to the metal bump, respectively. Film formation conditions thereof are set to provide metal films with a desired quality and thickness. Thus, penetration of moisture from the pad or the periphery into a ferroelectric capacitor can be prevented and therefore, occurrence of potential inversion abnormalities due to penetrated moisture can be effectively suppressed.Type: GrantFiled: November 18, 2011Date of Patent: March 12, 2013Assignee: Fujitsu Semiconductor LimitedInventors: Hirohisa Matsuki, Jun Fukuda
