Abstract: A heat exchanger includes: a first flow passage where first liquid flows; a second flow passage where second liquid flows; and a heat exchanger main body configured to exchange heat between the first liquid and the second liquid. The heat exchanger main body includes a cross-sectional area adjuster configured to change a flow passage cross-sectional area of at least one of the first flow passage and the second flow passage by thermal deformation. The cross-sectional area adjuster adjusts a value of the flow passage cross-sectional area in a low temperature range to be larger than a value of the flow passage cross-sectional area in a high temperature range.

Abstract: A lubrication structure includes a liquid drop splashing device and an electret portion. The liquid drop splashing device is configured to turn a lubricating liquid for lubricating machine-element components into liquid drops. The liquid drop splashing device is configured to splash the lubricating liquid turned into the liquid drops. The machine-element components configure contact parts. Each contact part is a part where corresponding adjacent machine-element components come into contact with each other. An electret portion is provided to a vicinity of each contact part. The electret portion is composed of an electret.

Abstract: A pair of toothed wheels that mesh with each other includes a plateau portion. The surface of the plateau portion is a plateau-structure surface formed on each tooth face of each of the pair of the toothed wheels, with peak portions of convexities, out of a plurality of concavities and the convexities provided on the each tooth face, being flat. A reduced valley depth Rvk of the plateau portion of one of the pair of the toothed wheels as defined in JISB0671-2 is greater than the reduced valley depth Rvk of the plateau portion of the other of the pair of the toothed wheels. The area occupied by the concavities in the plateau portion of the one of the toothed wheels is larger than the area occupied by the concavities in the plateau portion of the other toothed wheel.

Abstract: In a slip ring system (20) that includes: a slip ring (21) that is provided on a first rotating shaft (12) rotating about an axis (Ax); and a brush (22) that is provided in a case (11) and is pressed against the slip ring (21) and that transfers electricity between the slip ring (21) and the brush (22), a housing room (29) that is provided in the case (11) and houses the slip ring (21) and the brush (22) is provided, and a fluorinated liquid (FL) is filled in the housing room (29).
