Abstract: A first transmission system includes at least one gear disposed on a second axis, the at least one gear including a first outer gear disposed on an outermost side in a radial direction, and a second transmission system includes at least one gear disposed on the second axis, the at least one gear including a second outer gear disposed on an outermost side in the radial direction. The first outer gear and the second outer gear are spaced apart from each other in an axial direction. An oil cooler is disposed between the first outer gear and the second outer gear in the axial direction in such a manner as to overlap at least either the first outer gear or the second outer gear as viewed in the axial direction.

Abstract: A water discharge device that discharges water while reciprocally vibrating the water. The water discharge device includes a water discharge device body and a vibration generating element. The vibration generating element includes a water supply path, a collision portion, a vortex street path, and a discharge path. The vortex street path is formed by fitting an upstream fitting portion of an upstream member and a downstream fitting portion of a downstream member to each other. The upstream member or the downstream member is provided with a vibration reducing portion that reduces vibration of the upstream member due to vortices generated in the vortex street path. The upstream fitting portion or the downstream fitting portion is elastically deformed by a predetermined amount due to the provision of the vibration reducing portion.

Abstract: There have been cases where transistors formed using oxide semiconductors are inferior in reliability to transistors formed using amorphous silicon. Thus, in the present invention, a semiconductor device including a highly reliable transistor formed using an oxide semiconductor is manufactured. An oxide semiconductor film is deposited by a sputtering method, using a sputtering target including an oxide semiconductor having crystallinity, and in which the direction of the c-axis of a crystal is parallel to a normal vector of the top surface of the oxide semiconductor. The target is formed by mixing raw materials so that its composition ratio can obtain a crystal structure.

Abstract: A coil component includes a core including a winding core portion and a pair of flange portions provided at both ends of the winding core portion, electrode portions provided in the flange portions, a wire wound around the winding core portion, and a magnetic plate fixed to the flange portions. The magnetic plate includes an annular first planar portion, a second planar portion that is located inside the inner circumference of the first planar portion and has a step between the first and the second planar portions, and a connection surface portion connecting the inner circumference of the first planar portion to the outer circumference of the second planar portion. The connection surface portion is configured by annularly disposing at least three slopes inclined with respect to the direction orthogonal to the first planar portion and has chamfered portions each being disposed between adjacent slopes.

Abstract: A thermal spray material includes granules of an oxyfluoride of yttrium (YOF). The granules may contain a fluoride of yttrium (YF3). The granules preferably have an oxygen content of 0.3 to 13.1 mass %. The granules preferably have a fracture strength of 0.3 MPa or more and less than 10 MPa. Part of yttrium (Y) of the granules may be displaced with at least one rare earth element (Ln) except yttrium, the molar fraction of Ln relative to the sum of Y and Ln being preferably 0.2 or less.

Abstract: A vessel propulsion apparatus includes a nozzle, a deflector, and a forward bucket (hereinafter referred to as “F bucket”). In a state in which the F bucket is in a closed position and the deflector is positioned at a left side, water jetted obliquely rearward to the left from the deflector is guided by the F bucket in a left guiding direction that is tilted further to the left than a direction of jetting of water from the deflector. In a state in which the F bucket is in the closed position and the deflector is positioned at a right side, water jetted obliquely rearward to the right from the deflector is guided by the F bucket in a right guiding direction that is tilted further to the right than the direction of jetting of water from the deflector.

Abstract: This invention is a method for producing a cerium-based abrasive which includes: a step of grinding raw material for the cerium-based abrasive; a step of roasting the ground raw material; and a step of subjecting the roasted raw material to wet processing, the method being characterized in that it further includes a lower-temperature re-roasting step of heating the wet-processed raw material at 200 to 700° C. In the invention disclosed in this application, an abrasive with particularly preferable properties can be produced by fully drying the wet-processed raw material in a drying step, and subsequently subjecting the dried raw material to the lower-temperature re-roasting step.
