  • Publication number: 20030049071
    Abstract: A ball joint comprises a ball stud having a stud portion at a middle thereof, a ball portion and a screw portion at opposite sides of the stud portion, and a seat surface portion facing the screw portion between the respective portions, and a bearing member into which the ball portion is slidably fitted so as to universally pivotably-support the ball stud, so that the stud portion is inserted through a mounting member, and a nut is screwed with the screw portion projected from the mounting member, and the seat surface portion abuts and is fastened to the mounting member by fastening the nut to the mounting member. The seat surface portion abutting the mounting member is subjected to a co-rotation preventing process which prevents the ball stud from co-rotating along with the nut when the nut is fastened.

  • Patent number: 6395588
    Abstract: The impurity concentration contained in a layer on an electron supply layer of a high electron mobility field effect transistor is set in the range of 1˜1016 to 1˜1017 atoms/cm3, or the bandgap of a Schottky layer is set wider than that of the electron supply layer. Otherwise, in the steps of manufacturing the high electron mobility field effect transistor, after a silicon nitride film has been formed on a GaAs buried layer in which a second recess is formed and in a region on the inside of a first recess formed in a GaAs contact layer, the GaAs buried layer is still heated.
