  • Publication number: 20090298730
    Abstract: The invention provides a metalworking oil composition which is used for a very small amount of oil-feeding type metalworking method, said composition comprising a base oil selected from the group consisting of natural fats and oils, derivatives thereof and synthetic ester oils; and an antirust agent comprising a sorbitan fatty acid ester and a phospholipid, and a metalworking method using the composition and metalwork obtained by the metalworking method. The oil composition shows excellent lubricity and antirust property and is suitably used for metalworking of metallic materials such as cast iron, steel, stainless steel, and nonferrous metal (such as Al alloy and Mg alloy) by a method in which a very small amount of oil is supplied.

  • Publication number: 20090267750
    Abstract: More rapid and effective communication is performed between mobile units that cannot communicate directly due to impediments to communication that block signals. A mobile unit communication apparatus (1), including a wireless transceiver (9), is provided at a mobile unit. At the mobile unit communication apparatus (1), a surrounding object detection unit (6) detects objects surrounding the mobile unit. The surrounding communication impediment detection unit (7) detects a likelihood of an impediment to communication in the surroundings of the mobile unit from conditions for surrounding objects detected by the surrounding object detection unit (6). A relay communication unit (16) transmits information received by the wireless transceiver (9) from the wireless transceiver (9).
