摘要： A magnetic field generator includes a plurality of magnets on support members disposed opposite to each other across a gap. The plurality of magnets include: first magnets having a magnetization direction orthogonal to a support surface of each of the support members; and second magnets having a magnetization direction parallel to the support surface, and form a Halbach magnet array. Either of the first magnets or the second magnets has a first dimension orthogonal to the support surface which is smaller than a first dimension of the other of the first magnets or the second magnets, either of the first magnets or the second magnets being formed into a recessed shape as viewed from a side of the gap.

摘要： Provided is a method for manufacturing an Ni-based alloy member in which the equilibrium amount of γ′ phase precipitation at 700° C. is from 30 to 70 volume %. The method includes the steps of preparing an Ni-based alloy powder having a predetermined chemical composition; forming a precursor body wherein an average grain diameter of the γ phase grains is 50 μm or less, by using the Ni-based alloy powder; and heating the precursor body to a temperature at least the γ′ phase solvus temperature and subsequently slow-cooling the heated precursor body from the temperature to a temperature at least 100° C. lower than the γ′ phase solvus temperature at a cooling rate of 100° C./h or lower. There is obtained a softened body in that the γ′ phase particles of at least 20 volume % precipitate between/among the γ phase grains having an average grain diameter of 50 μm or less.

摘要： A repair method of a stator iron core which has a slot for accommodating a stator coil, and is formed by laminating silicon steel sheets. The method is implemented by moving a part of the silicon steel sheets which form the stator iron core while holding the stator coil in the slot to form a gap between the laminated silicon steel sheets of the stator iron core in the existence of a damaged part, and adding an insulation to the damaged part of the silicon steel sheet from the gap formed between the laminated silicon steel sheets to repair the damaged part of the silicon steel sheet.

摘要： An automatic landing system includes an imaging device mounted on a vertical take-off and landing aircraft; a relative-position acquisition unit that performs image processing on an image of a marker at a target landing point, and that acquires a relative position between the aircraft and the target landing point; a relative-altitude acquisition unit for acquiring a relative altitude between the aircraft and the target landing point; and a control unit for controlling the aircraft in a plurality of control modes so that the relative position becomes zero. The control modes include a hovering mode in which the relative altitude of the aircraft is lowered to a predetermined relative altitude when the relative position is within a first threshold value. A transition to a landing mode occurs upon satisfying predetermined conditions including the relative position being within a predetermined threshold value less than the first threshold value.

摘要： A burner assembly includes a plurality of bumers for mixing fuel and air. Each of the plurality of burners includes: at least one fuel nozzle for injecting the fuel; and a mixing passage into which the fuel injected from the at least one fuel nozzle and the air are introduced. Each fuel nozzle includes a protruding portion protruding upstream of an inlet of the mixing passage in a flow direction of the air. Each fuel nozzle includes a fuel injection hole formed on a side surface of the protruding portion. At least a portion of a first air passage for flowing the air is formed inside the protruding portion. The first air passage includes: an inlet formed on a surface of the protruding portion on an upstream side of the fuel injection hole in the flow direction of the air; and an outlet formed on a side surface of the protruding portion or a passage wall of the mixing passage. At least a portion of the outlet is formed downstream of the fuel injection hole in the flow direction of the air.

摘要： This exhaust gas processing equipment is provided with an exhaust line through which exhaust gas discharged from a boiler circulates, a carbon dioxide recovering device for recovering carbon dioxide included in the exhaust gas, and an exhaust gas heating device provided downstream of the carbon dioxide recovering device to heat the exhaust gas. The carbon dioxide recovering device includes a first medium line through which a first medium circulates, and a second medium line through which a second medium higher in temperature than the first medium circulates. The exhaust gas heating device includes a first heating unit for heating the exhaust gas by means of heat exchange with the first medium, and a second heating unit for heating the exhaust gas passing through the first heating unit even more by heat exchange with the second medium.

摘要： An opposed-piston engine according to an embodiment is a first fuel injection device configured to inject fuel from a circumferential wall surface of at least one cylinder into the cylinder, and a second fuel injection device disposed to be displaced in a circumferential direction so as to be opposite to the first fuel injection device across an axial center of the cylinder. Each of the first fuel injection device and the second fuel injection device includes a plurality of injection holes having different injection directions, in a cross-section orthogonal to the axial direction. A direction directed by a first downstream injection hole is configured to pass through a second injection region, and a direction directed by a second downstream injection hole is configured to pass through a first injection region.
