摘要： Using three-dimensional shape data, the shape of a blade, which is an additive manufacturing product, is divided into multiple layers according to the height of a bead. Each layer of the additive manufacturing product that has been divided into multiple layers is divided by fitting regions of a set shape. By determining connecting lines for connecting the divided regions to each other and computing the extension directions of protrusions, planned lines for bead formation along said extension directions are determined. The additive manufacturing product is shaped by forming beads along planned bead formation lines.

摘要： Provided is a reliquefaction device with which a gas gasified from a liquid can be efficiently reliquefied. A plurality of flow passages include: a mixing flow passage which is connected to the downstream end section of one among a liquid flow passage and a gas flow passage and allows a fluid mixture to flow so that a reliquefaction promoting liquid flowing through the liquid flow passage and a reliquefaction target gas flowing through the gas flow passage are mixed and the reliquefaction of the reliquefaction target gas is promoted by direct heat exchange; and a gas cooling flow passage which allows a coolant to flow and cool the reliquefaction target gas by means of indirect heat exchange with the reliquefaction target gas through a separation wall, thereby suppressing the gasification of the reliquefaction promoting liquid when the reliquefaction target gas is mixed with the reliquefaction promoting liquid flowing through the liquid flow passage.

摘要： A compressed air energy storage power generation apparatus includes a power demand receiving unit that receives a power demand value of a consumer facility. The apparatus includes a first air supply valve that adjusts a flow rate of compressed air to be supplied from a low-pressure tank to an expander, a second air supply valve that adjusts a flow rate of compressed air to be supplied from a high-pressure tank to the expander, and a control device configured to open the first air supply valve according to the power demand value in a state where the second air supply valve is closed when the power demand value is less than a predetermined threshold, and to open the second air supply valve according to the power demand value when the power demand value is equal to or greater than the predetermined threshold.

摘要： Provided is a tire testing machine including a tire stripper capable of separating the tire from the upper rim well. The tire stripper includes first and second pressing mechanisms pressing the tire downward, a linking mechanism linking the first and second pressing mechanisms so as to cause them to move in directions of coming close to or separating from each other while keeping a mutually symmetrical positional relationship across the upper spindles radially thereof, and a positioning mechanism operating the linking mechanism to allow the first and second pressing mechanisms to be positioned.

摘要： A method for manufacturing a built-up object, in which the built-up object includes a plurality of blades provided around a shaft body at circumferential intervals, and concave portions provided between adjacent ones of the blades, each of the concave portions having a curved shape in a section perpendicular to an axial direction, the method includes: a building step of depositing weld beads obtained by melting and solidifying a filler material on a circumferential surface of a base material having a circular shape in a sectional view and having a larger diameter than a bottom portion circle passing through bottom portions of the concave portions, thereby forming built-up portions to serve as the blades; and a cutting step of cutting parts of surfaces of the built-up portions and the circumferential surface of the base material, thereby forming the blades and the concave portions between the blades.
