Abstract: In an engine oil filter system in which: a filter-attachment base is joined to one side surface of an engine; and an oil filter which filters lubricating oil supplied to the engine from an oil pump is attached to the filter-attachment base, an oil cooler for cooling down the lubricating oil transferred between the engine and the oil filter is formed integrally with the filter-attachment base. Accordingly, it is possible to provide an inexpensive engine oil filter system which includes an oil cooler constituted by utilizing a filter-attachment base, and which thus eliminates the need to modify an oil filter and also the need to form, on an engine, an attachment portion to which the oil cooler is exclusively attached.

Abstract: Provided are a polarization plate which has a high mechanical strength, which does not impair a visibility even under a high temperature and high humidity, which is excellent in flexibility and abrasion resistance, and which reduces a visible disturbance such as color unevenness due to a size change, as well as a liquid crystal display device using the polarization plate.
