    摘要: A method and system is provided for determining at least one operating characteristic associated with an inductor in a power converter system. The operating characteristic may be current through the inductor. The power converter system may be of the type used in a hybrid electric vehicle (HEV) to convert electric power from a high-voltage traction battery to drive an electric motor and/or a generator in the HEV.

    摘要: An optical disc drive includes: an optical head with an actuator and a photodetector; a tracking driver outputting a drive signal to the actuator; a first tracking error signal generator for generating a first tracking error signal based on an output signal of the photodetector; first and second lens position control sections for respectively outputting first and second lens position control signals to the tracking driver; and a selector for selectively supplying the first tracking error signal to the first or second lens position control section according to a moving velocity of the optical head during a seek operation. The first lens position control signal is obtained by extracting signal components, of which the frequencies are equal to or lower than a predetermined frequency, from the first tracking error signal. The second lens position control signal is obtained by extracting DC components of the first tracking error signal at on-track points thereof.

    摘要: A hydrogen plasma downstream treatment equipment comprises a first gas supply source for supplying a hydrogen gas, a second gas supply source for supplying a nitrogen fluoride gas, and a tube-like chamber used for surface treatment of a semiconductor layer by use of the hydrogen gas and the nitrogen fluoride gas. The chamber includes a plasma generator for activating the hydrogen gas and the nitrogen fluoride gas by introducing the nitrogen fluoride gas in which a flow rate ratio of the hydrogen gas and the nitrogen fluoride gas is in excess of 4, a processor placed in a downstream of the plasma generator to place the semiconductor layer therein, and gas flow controlling means for controlling the first gas supply source and the second gas supply source so as to set a flow rate of the nitrogen fluoride gas four times a flow rate of the hydrogen gas.

    摘要: A motor drive method is provided which is capable of preventing suspension of operation of an industrial robot, and preventing deviation of the track of movement from a command track, attributable to an overload state of a motor. Output torque command values for motors for various axes of the robot are detected (S1). When any one of the detected values exceeds a predetermined value, which is determined in accordance with the maximum output torque of each corresponding one of the motors for the various axes, an amount of move command per unit time, for every one of the axes, is reduced. The amount of move command per unit time is reduced by using the torque command values thus increased, the product of an override value and a coefficient obtained in accordance with the differential of the torque command values (S3, S6 and S14), whereby the overload state of the motor is prevented.
