In the process of cutting the outer circumference 10o of a hollow rotating shaft 10 by using a finishing turning tool 36, the position of the finishing turning tool 36 is adjusted in the direction orthogonal to the virtual reference shaft center VS so that the center position CPo of the outer circumference 10o of the hollow rotating shaft 10 is deviated from the virtual reference shaft center VS in the same direction as the direction of the deviation vector Di by an amount corresponding to the magnitude |Di| of the deviation vector Di. This can reduce the unbalance to zero also in the middle of the shaft and sufficiently reduce runout of the hollow rotating shaft 10 even if the rotation speed of the hollow rotating shaft 10 increases. Accordingly, it is possible to further improve the reliability of the hollow rotating shaft 10 at high rotation speed.

A liquid fuel production method of the present invention includes: a saccharification step in which a biomass is saccharified; a methane fermentation step in which a saccharified liquid acquired in the saccharification step undergoes methane fermentation; and a biogas to liquid (BTL) step in which a liquid fuel is generated from a biogas acquired in the methane fermentation step.


A power-receiving structure (10) is provided in a ship (1) and includes a power-receiving coil (7) capable of wirelessly receiving electric power from a power-supplying coil (5) on a land-side and an outer wall surface-forming section (9) forming an outer surface of side of the ship, and the power-receiving coil is provided on an inside of the ship from the outer wall surface-forming section, and an electromagnetic field-transmissive section (9a) formed of a material through which an electromagnetic field propagates is provided in an opposing portion to the power-receiving coil in the outer wall surface-forming section. According to the present invention, the power-receiving coil is not protruded from the outer surface of side of the ship and can wirelessly receive electric power from the power-supplying coil on the land-side through the electromagnetic field-transmissive section. Accordingly, the power-receiving coil does not disturb the navigation of the ship and is not required to be pulled into the ship after the supply of the electric power to the ship is finished.

A uniflow-scavenged two-cycle engine (100) includes: a cylinder (110) in which a combustion chamber (124) is formed; a piston (112); a scavenging chamber (122) that surrounds one end side of the cylinder in the stroke direction of the piston and to which compressed active gas is guided; a scavenging port (118) that is provided in a portion of the cylinder which is positioned in the scavenging chamber and suctions active gas from the scavenging chamber to the combustion chamber in response to a sliding motion of the piston; a fuel injection opening (126) that is provided on an outer side of the cylinder in a radial direction thereof from the scavenging port and injects fuel gas into the active gas which is suctioned into the scavenging port; and a fuel injecting valve (128) that opens and closes a fuel supply path (144) through which a fuel tank (140), in which the fuel gas is stored, communicates with the fuel injection opening. In addition, the fuel injecting valve is disposed in an isolated space (146) isolated from the scavenging chamber.


Provided is a first coil device that faces a second coil device in a facing direction, and wirelessly transmits or receives power, the first coil device including a first coil portion, and a first auxiliary magnetic member provided adjacent to the first coil portion in a first direction orthogonal to the facing direction. The first auxiliary magnetic member is configured to be closer to the second coil device with increasing distance in the first direction from the first coil portion.

To prevent a height difference from being produced between a metal sheath and a paint layer formed on a vane surface of a vane body. A coating apparatus includes a jig (10) adapted to support a guide vane (V) equipped with a metal sheath (S) for covering a leading edge portion (LE); a nozzle (4) adapted to spray paint onto a vane body (Va); a robot (5) adapted to move the nozzle; and a control unit (6) adapted to control a spraying operation of the nozzle (4) and robot (5). The jig (10) includes a movable covering body (15) adapted to separably cover the metal sheath (S) and cover an exposed portion (Ta) of adhesive between a lateral edge portion (Sr) of the metal sheath (S) and the vane surface (Vd) of the vane body (Va), and a covering body drive unit (20) adapted to move the movable covering body (15) between a state in which the movable covering body (15) covers the metal sheath (S) and a state in which the movable covering body (15) is separated from the metal sheath (S) while covering the metal sheath (S). The control unit (6) performs control to make transition from a sheath cladding coating mode to a finish coating mode.
