    摘要: [Objectives] The present invention provides a non-aqueous secondary battery in which a material containing Si and O as constituent elements is used in a negative electrode. The present invention provides a non-aqueous secondary battery having good charge discharge cycle characteristics, and suppressing the battery swelling associated with the charge and the discharge. Also, the present invention relates to a negative electrode that can provide the non-aqueous secondary battery. [Solution] The negative electrode includes a negative electrode active material, including a composite of a material containing Si and O as constitution elements (atom ratio x of O to Si is 0.5≦x≦1.5) in combination with a carbon material, and graphite. The graphite has an average particle diameter dg (μm) of 4 to 20 μm. The material containing Si and O as constitution elements has an average particle diameter ds (μm) of 1 μm or more. The ratio ds/dg (i.e., ds to dg) is 0.05 to 1. The material containing Si and O as constitution elements has a crystallite diameter of 50 nm or less, the crystallite diameter is calculated from a half width at a (220) plane of Si obtained by an X-ray diffraction method, using Scherrer Formula. In 100 mass % of the composite of the material containing Si and O as constitution elements, and the carbon material, a ratio of the material containing Si and O as constitution elements is 70 to 95 mass %.

    摘要: A housing assembly for a fan unit includes an upper housing having a lower engaging portion adjacent to its lower end surface and a lower housing having an upper engaging portion adjacent to its upper end surface. When one of the upper and lower housings rotates relative to the other about a center axis of the housings in a first direction with the opposing end surfaces of the housings in axial contact, the lower and upper engaging portions engage with each other. While the lower and upper engaging portions are in engagement, one of the lower and upper engaging portions presses the other in both axial directions to cause elastic axial deformation of the other; and one of the lower and upper engaging portions presses the other toward both the first direction and a second direction opposite thereto to cause elastic circumferential deformation of the other.
