Abstract: An energy storage device includes an electrode body and an outer packaging. The outer packaging seals the electrode body. The outer packaging is constituted by a film-like outer packaging member. The outer packaging includes a first sealing portion sealed by joining surfaces that face each other in a state in which the outer packaging member is wrapped around the electrode body. A base portion of the first sealing portion is formed at the boundary between a first surface and a second surface of the outer packaging. The first surface has a larger area than the second surface. The first sealing portion does not overlap the first surface in a plan view.

Abstract: An electricity storage device has an electricity storage element sealed in a package member of a laminate material including a thermal adhesive resin layer. The package member has a housing portion having a substantially rectangular opening and formed to have a predetermined depth; a flange portion protruding outward from the circumferential edge of the opening; and a lid portion covering the opening and thermally bonded to the flange portion. The electricity storage element has a pair of electrode terminals protruding respectively from opposite longer-side edges of the opening and held between the flange portion and the lid portion.

Abstract: 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.

Abstract: There is provided a titanyl sulfate hydrate powder comprising 25 to 40% by mass of titanium element in terms of TiO2, 40 to 60% by mass of sulfur element in terms of H2SO4, and niobium element in such an amount that a molar ratio of niobium element to titanium element (Nb/Ti) is 0.00005 to 0.012, with a molar ratio of the sulfur element content to the titanium element content (S/Ti) being 1.1 to 1.5, and comprising crystalline titanyl sulfate dihydrate (TiOSO4.2H2O). Thus, the present invention can provide a titanyl sulfate hydrate powder with a high dissolution rate in water and a production method therefor, as well as a method for producing an aqueous titanyl sulfate solution, a method for producing an electrolyte and a method for producing a redox flow battery, using the titanyl sulfate hydrate powder.

Abstract: 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.

Abstract: 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.

Abstract: 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.
