  • Publication number: 20100101831
    Abstract: The present invention relates to an electrical contact material having a surface layer made of a noble metal or an alloy having the noble metal as its main component, a method for manufacturing the same and an electrical contact using the same. Recently, electrical contact materials having excellent abrasion resistance are used for sliding electrical contacts such as a connector terminal of an automobile harness, a contact switch mounted in a cellular phone and terminals of a memory card. Although there have been known ones having an organic coating film composed of either aliphatic amine or mercaptan or a mixture of the both provided on the electrical contact material described above as the electrical contact materials having excellent abrasion resistance, they have had problems that even though they are effective with a low load of 0.5 N or below, abrasion accelerates when the load exceeds 0.5 N and sliding characteristics drop under a high-temperature environment.

  • Publication number: 20100086392
    Abstract: A method is provided of manufacturing semiconductor devices formed on a semiconductor wafer, including placing the wafer in a semiconductor container and conveying the container to a semiconductor manufacturing apparatus. An opening of the container is opposed to an opening of the apparatus such that an opener of the apparatus holds a lid of the opening the container. A key of the opener is inserted to a latch groove of the lid, and the key is rotated to contact a latch of the lid. The openings are connected such that a velocity differential pressure ratio obtained by dividing the maximum velocity when the opener holding the lid horizontally moves away from the opening of the container, by the differential pressure between the inside pressure and the outside pressure of the apparatus, is set to be 0.06 ((m/s)/Pa) or less, and then the wafer is processed.
