This copper alloy for electronic devices includes Mg at a content of 3.3 at % or more and 6.9 at % or less, with a remainder substantially being Cu and unavoidable impurities. When a concentration of Mg is given as X at %, an electrical conductivity (% IACS) is in a range of {1.7241/(0.0347X^(2)+0.6569X+1.7)}100, and a stress relaxation rate at 150 C. after 1,000 hours is in a range of 50% or less.


A deposition apparatus for cutting tools with a coating film capable of depositing the coating film in an appropriate temperature condition is provided. The deposition apparatus includes: a deposition chamber in which a coating film is formed on the cutting tools; a pre-treatment chamber and post-treatment chamber, each of which is connected to the deposition chamber through a vacuum valve; and a conveying line that conveys the cutting tools from the pre-treatment chamber to the post-treatment chamber going through the deposition chamber, the in-line deposition apparatus using a conveyed carrier on which rods supporting cutting tools are provided in a standing state along a conveying direction. The deposition chamber includes: a deposition region; a conveying apparatus; a heating region; and a carrier-waiting region.

An oil-water separation apparatus is provided which can easily separate and collect oil from a liquid mixture containing water and oil at low cost. The oil-water separation apparatus includes an oil-water-separating member configured to separate a liquid mixture containing water and oil into moisture and oil, and a liquid reservoir subdivided into an upper region and a lower region by the oil-water-separating member. The oil-water separation apparatus filters the liquid mixture by gravity. The oil-water-separating member includes a base which includes a channel for the liquid mixture. The oil-water-separating member is formed in the base, and the oil-water-separating member contains a fluorine compound which has an oil-repellency-imparting group and a hydrophilicity-imparting group. A drain port for discharging the moisture is formed in the lower region of the liquid reservoir.


The hydrophilic oil repellent includes one or more types of nitrogen-containing fluorine-based compounds. The nitrogen-containing fluorine-based compound includes any one hydrophilicity imparting group selected from the group consisting of anion type hydrophilicity imparting groups, cation type hydrophilicity imparting groups, and amphoteric type hydrophilicity imparting groups in the molecule.
