Abstract: To provide a technique capable of forming stable droplets. There is provided a microparticle sorting device including a microchip including a main flow path through which a liquid containing a microparticle flows, a sheath liquid flow path that communicates with the main flow path and through which a sheath liquid flows, and a sheath liquid introduction portion that introduces the sheath liquid, in which the sheath liquid flowing through the sheath liquid introduction portion is vibrated. Furthermore, there is also provided a microparticle sorting method including, in a microchip including at least a main flow path through which a liquid containing a microparticle flows, a sheath liquid flow path that communicates with the main flow path and through which a sheath liquid flows, and a sheath liquid introduction portion that introduces the sheath liquid, vibrating the sheath liquid flowing through the sheath liquid introduction portion.

Abstract: To provide a technique capable of stably forming droplets. There is provided a microparticle sorting device and the like including: an imaging element configured to acquire an image of fluid and a droplet at a position where liquid discharged from an orifice that generates a stream of the fluid is converted into a droplet; and a processing unit configured to determine a harmonic superposition amplitude ratio, a harmonic phase difference, and a superimposed wave voltage on the basis of states of a satellite droplet and a break-off point in the image.

Abstract: To reduce the weight of the movable body while simplifying the structure. Included are: a first movable body that is movable in a first movement direction with respect to a base body; a second movable body that is positioned on an opposite side of the first movable body from the base body and movable in a second movement direction different from the first movement direction with respect to the first movable body; and a first drive body and a second drive body that each apply driving force to the second movable body, in which the first movable body and the second movable body are integrally moved in the first movement direction with respect to the base body by the driving force of at least one of the first drive body or the second drive body, and the second movable body is moved in the second movement direction with respect to the first movable body by the driving force of at least one of the first drive body or the second drive body.

Abstract: A recess is formed on the periphery of each of through-holes that go through a rim cavity, and the outer surface of a rim part is cut while a seal member for sealing the through-hole is positioned on the recess. It is thereby possible to stably manufacture a vehicle wheel in which swarf tends not to remain inside the rim cavity. Furthermore, it is not necessary to avoid the seal member for sealing the through-hole when cutting the outer surface of the rim part, and the outer surface of the rim part can be cut without any distinction having to be made between the periphery of the through-hole and the rest of the outer surface. Any increase in manufacturing costs can be minimized.

Abstract: According to one embodiment, a dynamo-electric machine includes a rotor, a stator, a frame, a shaft sealing device, and a gas purity maintainer. The gas purity maintainer includes an expansion tank, a first mist collecting section, a valve unit, a drain pot, and an instrument panel. The first mist collecting section is provided in the middle of a scavenging pipe extending from the expansion tank to discharge a coolant gas from the expansion tank. A downstream in the first mist collecting section is higher than an upstream.

Abstract: A vehicle wheel according to the present invention includes a hollow-state hollow portion and a solid-state non-hollow portion inside an outboard bead seat in a radial direction, which are provided in series in a circumferential direction of the wheel, the non-hollow portion having a cross section with a larger area than a hole cross section of a valve hole and having the valve hole formed therein. This structure prevents a sealing structure for ensuring hermetic performance from being complicated as compared to a wheel having the valve hole in the hollow portion, thus simplifying a mounting structure of an air valve. A method for manufacturing such a vehicle wheel allows formation of the valve hole in the non-hollow portion. Machining dust generated through a cutting process can thus be prevented from entering the hollow portion and remaining therein.

Abstract: A method for manufacturing a vehicle wheel is suggested in which the vehicle wheel can provide function and effect of preventing molding defects during molding of an outer rim portion and/or an inner rim portion having sound absorbing spaces 25 and of reducing acoustic cavity noise that occurs in a tire-internal space by use of the sound absorbing spaces. After a separation groove having a curved shape groove bottom surface 55a is formed between a ring-shaped wall portion and partition wall portions, the ring-shaped wall portion is bent toward a flange portion, and the ring-shaped wall portion and the flange portion are welded together. The sound absorbing spaces which communicate with each other via communication gaps defined according to the separation groove are thereby formed in the outer rim portion and/or the inner rim portion.
