Abstract: An air sending device is provided with a cross flow fan including an impeller in which a plurality of blades is arranged annularly. Each of the blades includes a pressure surface, a suction surface, an inner peripheral end face, and an outer peripheral end face. The pressure surface of the blade satisfies the following relationship: a curvature of a second pressure-surface side curved surface>a curvature of a third pressure-surface side curved surface>a curvature of a first pressure-surface side curved surface. When a first, a second, and a third pressure-surface side area of a surface of part of a pressure surface side of the blade are projected on a chord line connecting the inner and outer peripheral end of the blade, a length of the third pressure-surface side area>a length of the first pressure-surface side area>a length of the second pressure-surface side area.

Abstract: An indoor unit includes: a casing that has an air outlet and an air inlet, and inside which an air passage is formed; a cross flow fan disposed in the air passage and configured to blow out, through the air outlet, air sucked in from the air inlet; a stabilizer configured to stabilize vortex of air caused by circulation of air and generated inside the cross flow fan upon rotation thereof; and a guide wall having a surface defining an outlet side air passage being a part of the air passage, the part being in downstream of the cross flow fan, wherein the stabilizer has a first surface that defines a surface opposite to the guide wall in the outlet side air passage, and a part of the outlet side air passage is formed such that a distance in a vertical direction from the first surface to the guide wall gradually decreases toward the downstream.

Abstract: A 3D-modeling system includes a first discharge section, a second discharge section, a stage, a heating section, and a control section, wherein the control section performs a modeling process molding a first molded object and a second molded object on a modeling surface by controlling the first and second discharge sections to discharge modeling materials having different plasticization temperatures from each other from the first and second discharge sections and a heating process by controlling the heating section configured to heat the molding materials discharged from the first and second discharge sections at different temperatures from each other, and the modeling process is performed such that a period in which the modeling material discharged from the first discharge section is deposited on the modeling surface and a period in which the modeling material discharged from the second discharge section is deposited on the modeling surface overlap each other.

Abstract: A part includes a base material, a colored layer, an intermediate layer, and a water-repellent-surface layer. The colored layer contains 35 at % to 99 at % of C, 0 at % to less than 40 at % of Cr, 0 at % to less than 15 at % of N, and more than 0 at % to less than 15 at % of O. The intermediate layer contains at least one metal atom selected from Cr, Zr, and Si; and an oxygen atom. The intermediate layer exhibits a sputtering time of 0.

Abstract: Disclosed is a faucet valve including: a first valve body including a first slide surface, and formed from an alumina-based sintered body; and a second valve body including a second slide surface, and formed from an alumina-based sintered body, the first and second slide surfaces at least partially being in contact with each other with water in between. At least part of the second slide body is formed from a first amorphous carbon layer. The hardness of the first amorphous carbon layer is equal to or less than that of the alumina-based sintered body forming the first valve body. In the first amorphous carbon layer, a ratio (ID/IG) of a D peak to a G peak, measured by Raman spectroscopy, is greater than 0.5 but less than 1.9.

Abstract: In an inspection of an object of inspection with use of X-rays, X-rays are output from an X-ray source disposed fixedly into a range of a predetermined solid angle and, while the object of inspection is moved along a plane within the output range of the X-rays, the X-rays are detected, in positions included in the solid angle and at a plurality of revolved points around an axis oriented vertical to the plane along which the object of inspection is moved, with its detecting surface tilted down toward the axis. Thus, the object can be inspected based on the detected X-rays.
