摘要： The present invention includes a control amount calculation unit which calculates two or more control amounts each indicating a driving condition of a rotary electric machine on the basis of output current from and a switching state in a power converter; a limitation range-provided command value generation unit which generates limitation range-provided command values relative to command values for the control amounts; and a switching state determination unit which determines a switching state such that each control amount falls within the limitation range of the corresponding limitation range-provided command value. For at least one of the limitation range-provided command values, the limitation range thereof is temporally changed on the basis of the driving condition of the rotary electric machine.

摘要： A power conversion device which reduces switching losses and stabilizes the output power. A switching-mode changer generates a reference signal for switching a mode of operation of the full-bridge circuit to a first switching mode or a second switching mode. In the first switching mode, an upper arm and a lower arm are switched synchronously, and a lower arm and an upper arm are non-conducting. In the second switching mode, the lower arm and the upper arm are switched synchronously, and the upper arm and the lower arm are non-conducting. The switching-mode changer adjusts the phase of the reference signal so that the reactive power is reduced.

摘要： This application discloses a control device for controlling a motor configured to drive an oscillatory cyclo-speed reducer including an oscillatory gear portion formed with at least one hole at an eccentric position. The control device includes an angle acquirer for acquiring input information about an input rotational angle indicating a rotational angle of the motor, an estimator for estimating an angular error between the input rotational angle and an output rotational angle indicating a rotational angle of the oscillatory cyclo-speed reducer based on a quantity of the hole(s) and a corrector for determining a compensation current value in correspondence to the angular error and setting a magnitude of a current to be supplied to the motor by correcting a command current value using the compensation current value.

摘要： Provided is an optical measurement apparatus including: a polarized light irradiation unit 10 that irradiates a subject Ob with irradiation light of which polarization is controlled; and a polarization imaging unit 20 that images a polarization state of measurement light occurring due to scattering, reflection, absorption, or the like of the irradiation light by the subject Ob, calculates all or a part of Stokes parameters of the measurement light, and measures a variation of a polarized component occurring between the irradiation light and the measurement light due to the subject Ob. Since the subject is irradiated with irradiation light of which a polarization state is controlled, it is possible to acquire subject information that is difficult to measure in a case of irradiating the subject with natural light, that is, non-polarized irradiation light, and it is also possible to suppress noise or a decrease in contrast that occurs when measuring polarization by irradiating the subject with irradiation light of which a polarization state is unstable.

摘要： An ultrasonic inspection device includes: a longitudinal ultrasonic sensor configured to emit and receive a longitudinal ultrasonic wave; and an ultrasonic transducer unit made of metal and having the shape of a polyhedron. The ultrasonic transducer unit includes: an output surface configured to be disposed facing an object to be inspected; an input surface on which the longitudinal ultrasonic sensor is disposed; and a conversion surface configured to, when the longitudinal ultrasonic wave input through the input surface is reflected by the conversion surface, convert the longitudinal ultrasonic wave into a transverse ultrasonic wave such that the transverse ultrasonic wave propagates toward the output surface, the conversion surface being tilted at a predetermined angle with respect to an in-plane direction of the output surface. Thermal conductivity of the ultrasonic transducer unit is lower than thermal conductivity of the object to be inspected.
