    摘要: A substrate 1 for growing nitride semiconductor has a first and second face and has a thermal expansion coefficient that is larger than that of the nitride semiconductor. At least n-type nitride semiconductor layers 3 to 5, an active layer 6 and p-type nitride semiconductor layers 7 to 8 are laminated to form a stack of nitride semiconductor on the first face of the substrate 1. A first bonding layer including more than one metal layer is formed on the p-type nitride semiconductor layer 8. A supporting substrate having a first and second face has a thermal expansion coefficient that is larger than that of the nitride semiconductor and is equal or smaller than that of the substrate 1 for growing nitride semiconductor. A second bonding layer including more than one metal layer is formed on the first face of the supporting substrate. The first bonding layer 9 and the second bonding layer 11 are faced with each other and, then, pressed with heat to bond together. After that, the substrate 1 for growing nitride semiconductor is removed from the stack of nitride semiconductor so that a nitride semiconductor device is provided.

    摘要: Windings of each phase in a three-phase AC motor are independent of one another. A motor control unit gives, to windings of each phase (U, V and W-phase), currents (IU, IV, IW) obtained by adding, to a fundamental sine wave current, a current having a frequency which is three times as high as that of the fundamental sine wave current. That is, IU=I·sin ωt+Ia·sin 3ωt: IV=I·sin(ωt+2/3π)+Ia·sin 3ωt: IW=I·sin(ωt+4/3π)+Ia·sin 3ωt Also, amplitude Ia of a current having a frequency which is three times as high as that of the fundamental sine wave current is set to a predetermined value smaller than amplitude I of the fundamental sine wave current.

    摘要: A discrete-type repetitive control unit which enables stable repetitive control even if a state variable of a controlled object is not observable, using time delay elements (Z.sup.-1). The number of time delay elements is equal to or greater than a value obtained by dividing a cycle period of a cyclic target input by a period of sampling the deviation between a controlled object output and the cyclic target input. Periodically applied to each of the time delay elements is a sum obtained by adding the product of the deviation and a first gain (h1, - - - , hn) associated with the time delay element, to the product of an input (u(k)) of the controlled object and a second gain (m1, - - - , mn) associated with the time delay element, and to an output (Wn(n+n), - - - , W1(k+1)) of a preceding element. The control unit periodically applies to the controlled object a sum (u(k)) obtained by adding the product of the deviation and a third gain (h0) to an output (W1(k)) of the last time delay element. The control unit achieves a stable operation of the controlled object with the flexibility to respond to variation in the cycle period of the target input and without causing a delay in following the target input which periodically changes in a single changing pattern.

    摘要: A servo motor controlling method for controlling both speed and current of a servo motor under digital control. An integration gain unit (22) and a loop proportional gain unit (26) of the current controlling loop are subjected to correction by respective gain units (23, 27) so as to be increased depending upon the rotational speed of the servo motor. Since a current loop gain is increased depending upon the rotational speed of the servo motor, the oscillation of the current loop does not occur at the time of low speed drive and stop, and the shortage of torque due to the lowering of the current loop gain at the time of high speed drive can be prevented.

    摘要: An output torque of a servomotor is controlled to prevent overrun of an injection mechanism in an injection molding machine. The injection mechanism is driven by the servomotor to perform an injection operation of the injection mechanism. The injection molding machine includes a torque limit circuit which limits a value of a torque instruction output from a servo circuit of the injection mechanism operating in an injection direction to a value of a torque limit instruction from a numerical control apparatus and does not perform a torque limit operation of a drive instruction in a direction opposite to the injection direction. Therefore, the servomotor for driving the injection mechanism can be rapidly decelerated to prevent overrun of the injection mechanism.
