  • Patent number: 6328128
    Abstract: An electric power steering apparatus has a torque sensor which, if the torsion of a torsion bar is within a predetermined angle, linearly outputs a detection signal converted by a first conversion ratio with respect to the torsion, and if the torsion has exceeded the predetermined angle and is within a limit angle, the torsion sensor outputs a detection signal converted by a second conversion ratio which is lower than the first conversion ratio. Further, if the detection signal has exceeded an upper threshold or dropped below a lower threshold, which thresholds being set outside the range of the detection signal outputted from the torsion sensor in its normal state in which the torsion of the torsion bar is within the limit angle, a determination is made that an abnormality has occurred in the torsion sensor.

  • Patent number: 6328857
    Abstract: Sputtering method and apparatus for forming a coating on both sides of a flat substrate or on the entire surface of a bulky substrate without involving rotation of the substrate. At least one pair of sputtering cathodes each having a target attached thereto are arranged in a film-forming chamber capable of controlling a vacuum atmosphere with their target sides facing each other, and a substrate is disposed in front of the targets. A voltage is applied to the sputtering cathodes in such a manner that the polarity alternates between the sputtering cathodes making the pair to induce a glow discharge between the sputtering cathodes. The target on each sputtering cathode is thereby sputtered and deposited on the substrate.
