Abstract: A manufacturing system of an additive manufacturing body is provided, by which the accuracy of evaluating a defect during additive manufacturing and the quality of the body can be improved. A manufacturing system of an additive manufacturing body of the present invention includes: an additive manufacturing device; an inspection device having a camera for photographing the powder layer or the solidified layer; and a control device that controls the additive manufacturing device and the inspection device, in which: the camera can photograph the powder layer for each powder layer forming step that is performed repeatedly, or can photograph the solidified layer for each solidified layer forming step that is performed repeatedly; and the control device selects a photographing condition of the camera according to the conditions of the additive manufacturing process.

Abstract: Provided is a heat-resistant titanium (Ti) alloy member having excellent mechanical characteristics and oxidation resistance at high temperatures and having less mechanical anisotropy, a method for producing such a titanium alloy member, and a product including such an alloy member. A titanium-based alloy member includes titanium (Ti) as a major element and at least 0.5 to 2.0 mass % of boron (B) and has a dispersion of fiber-like TiB particles precipitated in a polycrystal matrix phase, the TiB particles each having a long axis of 1 to 10 ?m and a short axis of 0.01 to 0.5 ?m or less and having an aspect ratio of 2 to 1000, the TiB particles precipitating in a crystallographically random direction in each of crystal grains of the matrix phase.

Abstract: The present invention is a lithium-ion secondary battery system having a lithium-ion secondary battery, potential measuring sections, a voltage applying section, an electric current measuring section, and a switching section.
