Abstract: The purpose of the present invention is to provide a lubricating oil composition capable of achieving good wear resistance and good scoring resistance of a bearing in addition to further fuel saving while maintaining durability and seizure resistance that can be used as a gear oil for a high-output, high-speed gear mechanism. A lubricating oil composition containing a combination of Fischer-Tropsch derived base oil having a low kinematic viscosity at high temperature, polyalphaolefin having a high kinematic viscosity at high temperature, and ester compound of a trivalent or higher polyol having a low kinematic viscosity at high temperature, and further contains a partial ester compound of an unsaturated fatty acid and a polyol, including a monoester compound of the unsaturated fatty acid and the polyol.

Abstract: A pressure-applying device includes a pressure-applying portion that applies pressure to a pressure-receiving object and a pressing portion that presses the pressure-applying portion toward the pressure-receiving object, the pressing portion having a hardness higher than a hardness of the pressure-applying portion. The pressure-applying portion includes plural projections that project from a back surface of the pressure-applying portion that faces the pressing portion toward a pressing surface of the pressing portion that faces the pressure-applying portion.

Abstract: A two-layer inside/outside air vehicular air-conditioning system which suppresses odor inside an air-conditioning case or inside a vehicular compartment is provided with an exhaust controller which uses an outside air intake port as an air exhaust port and which uses a compartment-side air discharge port opening/closing device to close all compartment-side air discharge ports. The exhaust controller also operates one or both of the blowers to cause air inside the first air passage and the second air passage to be exhausted via the air exhaust port.

Abstract: A two-layer inside/outside air type of vehicular air-conditioning system which takes measures against odor is provided, in particular, a two-layer inside/outside air type of vehicular air-conditioning system which does not require the provision of a new exhaust port or duct in the vehicle for dealing with odor is provided. That is, a two-layer inside/outside air type vehicular air-conditioning system is provided which suppresses odor inside an air-conditioning case or inside a compartment by being provided with an exhaust controlling means which uses one outside air intake port as an air exhaust port, uses compartment-side air discharge port opening/closing means to close all compartment-side air discharge ports, and operates one of the blowing means and does not operate the other of the blowing means so as to make air inside the first air passage and second air passage be exhausted from the air exhaust port.

Abstract: An air conditioning system for vehicles prevents pressure loss in an air conditioner casing from increasing by air-conditioning a passenger compartment while detouring around an air cleaning unit when the air conditioning situation is in an irregular air conditioning range, and improves passengers' comfort by cleaning and air-conditioning air by way of the air cleaning unit when the air conditioning situation is in a regular air conditioning range.

Abstract: A heat exchanger made of aluminum includes a plurality of tubes made of aluminum through which a fluid to be heat exchanged flows, the tubes having a metal surface of aluminum; fins made of aluminum arranged between the tubes for accelerating heat exchange between the fluid to be heat-exchanged and air, the fins having a metal surface of aluminum; a first protecting film of a chemical conversion coating formed on the metal surfaces of the tubes and fins and containing a metal component; and a second protecting film of an antimicrobial agent coating on the first protecting film, at least on the fins among the tubes and fins, the second protecting film having a chemical bond with the metal component of the first protecting film. An example of the antimicrobial agent is 2,2'-dithiobis(pyridine-1-oxide).
