  • Publication number: 20210272777
    Abstract: The present invention realizes a plasma treatment device with which a film deposition rate and film thickness of a film formed on a substrate can be made uniform. A plasma treatment device (1) includes: a plurality of antennas (20) for plasma generation arranged in a vacuum chamber (10); and a plurality of groups of multiple gas injection ports (30) arranged in the vicinity of lines (L1) that are substantially perpendicular to longitudinal directions (D1) of the plurality of antennas (20) and extend in a direction in which the plurality of antennas (20) are arranged with respect to each other. The plasma treatment device further includes a gas flow-rate control unit for controlling flow rates of gas injected from each of groups of the multiple gas injection ports (30).

  • Publication number: 20210262351
    Abstract: A rotary machine includes a rotor shaft that is rotatable about an axis, a plurality of blades extending radially outward from the rotor shaft and arranged in a circumferential direction, and a casing that covers the rotor shaft and the plurality of blades from an outer peripheral side. Each of the plurality of blades includes a blade body including a leading edge facing forward in a rotational direction of the rotor shaft, a trailing edge facing backward, and a tip facing radially outward, and a weight of the blade body is different between at least two of the plurality of blades.

  • Publication number: 20200400038
    Abstract: A rotary machine includes a rotary shaft configured to rotate around an axis and a blade row including a plurality of blades at intervals in a circumferential direction of the axis. Each of the blades includes a fiber laminate obtained by laminating a plurality of fiber sheets and a resin used for forming an outer shape of the blade by impregnating the fiber laminate. At least two of the blades in the blade row have fiber laminates having different structures.

  • Publication number: 20190087530
    Abstract: A method for designing the cross-sectional shape of the fuselage of a flying body having the fuselage extending in the roll axial direction, the section being taken on a plane perpendicular to the roll axial direction. This method is provided with: an initial setting step S12 for setting an initial cross-sectional shape, which is the initial cross-sectional shape of the fuselage having a cross-sectional shape that is not truly circular; load application steps S14, S21, S28 for analytically or experimentally preloading the fuselage having the initial cross-sectional shape; and a design shape setting step S17 for acquiring the cross-sectional shape of the preloaded fuselage as the design cross-sectional shape of the fuselage.
