    摘要: A semiconductor device includes a first group III-V nitride semiconductor layer, a second group III-V nitride semiconductor layer having a larger band gap than the first group Ill-V nitride semiconductor layer and at least one ohmic electrode successively formed on a substrate. The ohmic electrode is formed so as to have a base portion penetrating the second group III-V nitride semiconductor layer and reaching a portion of the first group III-V nitride semiconductor layer disposed beneath a two-dimensional electron gas layer. An impurity doped layer is formed in portions of the first group III-V nitride semiconductor layer and the second group III-V nitride semiconductor layer in contact with the ohmic electrode.

    摘要: Data is read out from a disk in which the data is recorded in the perpendicular magnetic recording system by a head, amplified by a head preamplifier, and signal-processed by a read channel LSI. A read-out processing unit of a HDD controller sends out signals processed by the read channel LSI as an output of the perpendicular magnetic recording system. Further, a cut-off frequency controlling unit of the HDD controller determines a cut-off frequency of a high-pass filter of the head preamplifier based on a data transfer rate read out by the read-out processing unit, controls a cut-off frequency changing unit, and changes the value of the cut-off frequency.

    摘要: A first calculation device is provided that calculates a ratio of a target torque equivalent value of an engine to a maximum torque equivalent value of the engine, as a pressure ratio equivalent value. A second calculation device is also provided that calculates a flow velocity of air to flowing through a throttle valve in the engine, based on the pressure ratio equivalent value calculated by the first calculation device. A third calculation device is further provided that calculates a target throttle valve opening, based on the flow velocity calculated by the second calculation device. With this configuration, the target opening of a throttle valve corresponding to the requested engine torque, without using the pressures before and after the throttle valve section.
