An environment adjustment system includes an acquisition unit configured to acquire environmental information of an environment related to a user, a drafting unit configured to draft an action plan to recommend to the user based on the environmental information, a transmission unit configured to transmit the action plan to the user's terminal, and a confirming unit configured to confirm whether the user has performed the action plan. When the drafting unit drafts a new action plan for another user or for the user, it drafts the new action plan using a result of the confirmation by the confirming unit.

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.

Heat exchanger

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.

Lubrication structure and transmission

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.

Toothed wheels and transmission

This lubricating deviceis equipped with an oil panthat stores therein lubricating oil, a micro bubble generatorthat mixes the lubricating oil with air to produce micro bubbles and supplies the lubricating oil in the oil panwith the micro bubbles, and an oil pumpthat pressurizes the lubricating oil in the oil panto supply the micro bubble generatortherewith. Further, in this lubricating device, the micro bubble generatorhas an air inlet portiondisposed inside the oil panat a predetermined position with respect to an oil surface height (oil level) of the lubricating oil in the oil pan

Lubricating device

A switching apparatus is provided in a hydraulic control apparatus having a fluid transmission apparatus; a lockup clutch; a switching valve that controls engagement of the lockup clutch; and a control oil pressure generation apparatus that pressurizes oil and outputs a control oil pressure to control activation of the switching valve. The switching apparatus executes a control to warm the oil input into the control oil pressure generation apparatus if the temperature of the oil is below a predetermined temperature and prohibits execution of the control to warm the oil input into the control oil pressure generation apparatus if the temperature of the oil equals or exceeds the predetermined temperature.
