  • Patent number: 6973708
    Abstract: A method for reducing ac loss in a superconducting coil of cable-in-conduit type superconductor made from chrome-coated compound superconducting strands, characterized in that when a superconducting coil is produced by the wind-and-react technique, bending or twist strain is applied in an amount of 0.15˜0.3% to the conductor cable portion after it has been heat-treated to form the superconducting compound, thereby separating the individual superconducting strands the chrome coat on which sintered as the result of heat treatment and further characterized in that the applied bending or twist strain is thereafter reverted to 0.1% or less, thereby reducing the ac loss of the superconducting coil.

  • Patent number: 6148257
    Abstract: In a vehicle equipped with a continuously variable transmission, sensors detect a vehicle speed, an accelerator depression degree and an output rotation speed of the transmission. The minimum required drive shaft drive torque is calculated from the vehicle speed and the accelerator depression degree. A target input rotation speed of the transmission for achieving the minimum required drive shaft drive torque with the least engine fuel consumption is calculated according to the vehicle speed. The input rotation speed is controlled to this target input rotation speed. The target engine output torque to generate the minimum required drive shaft drive torque is calculated, and an engine throttle opening is controlled to obtain this torque. As a result, the required vehicle drive force is obtained with the minimum engine fuel consumption.
