    Abstract: An apparatus for estimating a transfer function of at target object having divided systems is disclosed. The apparatus acquires an estimation equation to estimate the transfer function of the target object, and determines, for each arithmetic operation in the estimation equation, whether the arithmetic operation is an addition or a multiplication. For the multiplication, the apparatus performs the multiplication of frequency response characteristics in the frequency domain. For addition, the apparatus converts the frequency response characteristics into time response characteristics, performs the addition of the time response characteristics in the time domain, and reconverts a result of the addition into the frequency domain.

    Abstract: An object of the present invention is to provide a polyester resin that has a high degree of freedom in design and that can have excellent biodegradability even with an increased molecular weight. A polyester of the present invention contains a hydroxy group-containing dicarboxylic acid component and a diol component (excluding a hydroxy group-containing dicarboxylic acid component) as copolymerization components, wherein more than 50 mol % of an aliphatic diol component is contained in 100 mol % of the diol component, the polyester has a number average molecular weight of 3000 or higher, and the polyester has a total hydroxyl value of 1000 eq/ton or higher.

    Abstract: In a first control state, it is determined which one of a first failure pattern (FP1) and a second failure pattern (FP2) is a failure pattern (FT), and in a second control state, it is determined which one of a first lower-stage-side failure pattern (LF1) and a second lower-stage-side failure pattern (LF2) is a lower-stage-side failure pattern (LF), and it is determined which one of a set of upper-stage-side arms of a first inverter (11), a set of lower-stage-side arms of the first inverter (12), a set of upper-stage-side arms of a second inverter (12), and a set of lower-stage-side arms of the second inverter (12) is failure-side arms, based on a result of the determination in the first control state and a result of the determination in the second control state.
