Abstract

A recycled resin material data management system comprises an input device, a processing device, and an output device. The input device acquires measurement data of recycled resin material, or waste resin material that is the raw material of the recycled resin material. The processing device calculates a characteristic amount pertaining to the composition and/or the physical properties of the recycled resin material or the waste resin material, on the basis of the measurement data, predicts the remaining life of the recycled resin material or the waste resin material on the basis of the characteristic amount thereof, and discriminates whether mechanical recycling or chemical recycling is to be applied to the waste resin material. The output device outputs at least one among the measurement data, the characteristic amount data, the remaining life data, and the discrimination result. Due to this configuration, low-quality waste resin material can be effectively utilized as much as possible, and the quality of recycled resin material can be ensured.

Abstract

This system receives, from a user, an input of domain knowledge relating to a reproduction object by a simulator, and stores, in a storage device, influencing factor candidate data which is based on the domain knowledge and which represents the parent‐child relationship between factors. On the basis of data representing simulation results and the influencing factor candidate data, the system generates a first causal sequence model for entities relating to simulation differences (differences between the simulation results and actual results), regarding the entities and candidate factors influencing the entities. Further, on the basis of actual result data representing the actual results and the influencing factor candidate data, the system generates a second causal sequence model for the entities, regarding the entities and candidate factors influencing the entities. The system extracts one or more differences between the first causal sequence model and the second causal sequence model.

The power conversion device comprises: a control logic unit that generates PWM commands for switching the power semiconductor element having one or more gate control terminals; and a gate drive unit that generates the gate commands by delaying the PWM commands by a predetermined time. The control logic unit observes the pulse states of the PWM commands when receiving a detection signal indicating an abnormality in the power conversion device and superimposes a pulse signal as an emergency stop command on the PWM commands at a timing that satisfies the minimum on-time specified in the use conditions of the power semiconductor element. The gate drive unit turns off the gate commands to the one or more gate control terminals on the basis of the PWM commands on which the emergency stop command is superimposed.

Abstract

This power conversion device comprises: a first leg in which a first upper arm and a first lower arm are connected in series; a second leg in which a second upper arm and a second lower arm are connected in series; a smoothing capacitor connected in parallel with the first leg and the second leg; a first auxiliary inductor, one end of which is connected to the connection point between the first upper arm and the first lower arm; a second auxiliary inductor, one end of which is connected to the connection point between the second upper arm and the second lower arm; and a smoothing inductor, one end of which is connected to the other end of the first auxiliary inductor and the other end of the second auxiliary inductor. The power conversion device performs power conversion between a power supply system connected between the other end of the smoothing inductor and one end of the smoothing capacitor and a power supply system connected between both ends of the smoothing capacitor. This makes it possible to reduce switching loss while reducing the size of the smoothing inductor, thereby enabling to achieve a reduction in size and an increase in efficiency.

Abstract

According to the present invention, if, when a calculated unconfirmed stopping limit position is compared with operation timetable course information D5 received from an operation management device 12, said stopping limit position is not on the compared course, a traveling schedule course (route B) for the operation timetable information D5 and a congruent course Y, which is a congruent portion of a course on which it is possible to travel based on the calculated non-confirmed stopping limit position, are extracted. A new stopping limit position G3 is calculated on the outside of a route indication portion 30 which is most distant in the train traveling direction within the range of the congruent course Y. Subsequently, a ground ATP device 14 transmits the stopping limit position G3 generated by a congruent course stopping limit position generation unit 14C to an on-train ATP device 20 as stopping limit position information D4. The on-train ATP device 20 comprises a train control unit 20B, and with the train control unit 20, a train stopping pattern P is generated on the basis of the received stopping limit position information D4 and train control is performed.

Abstract

The present invention increases interpretability of attribute values and attributes of training data and test data for a learning model. Accordingly, regression models, in which latent variables outputted from MFCVAE in response to input of input data including reference data having a plurality of attributes assigned with attribute values are defined as explanatory variables and the attribute values are defined as objective variables, are set for the respective attributes. From the latent variables and the attribute values, prediction values of the attribute values at which prediction errors with respect to the attribute values become minimum and regression coefficients of the regression models are calculated for the respective attributes. On the basis of the prediction values and the regression coefficients for the respective attributes, function values of loss functions, of the MFCVAE, obtained by adding additional terms based on indices which are for the respective attributes and of which the values become smaller as the adaptation of the latent variables and the attribute values to the regression models becomes better are calculated. By error backpropagation based on the function values, a model parameter of the MFCVAE is updated. As described above, model training of MFCVAE is executed.

Abstract

In order to provide a PWM control technology that can output an accurate fundamental wave voltage while reducing harmonic current by adding an operation amount to modulation waves of three phases in accordance with the saturation states of the modulation waves of the three phases, this drive control apparatus for a rotating electrical machine drives the rotating electrical machine by controlling an electric power conversion device by means of a PWM signal that is generated by a PWM control unit from a carrier wave and three-phase modulation wave command values generated on the basis of a voltage command value. When the absolute value of a modulation wave command value of one phase, among the three-phase modulation wave command values, is greater than a prescribed value, a modulation wave operation unit, which is provided to the preceding stage to the PWM control unit, stops switching of the one phase by saturating the modulation wave, to the maximum value of the absolute value of the carrier wave, by adding an operation amount to the modulation wave command value of the one phase, and also adds the operation amount to the modulation wave command values of the remaining two phases. Moreover, when the absolute values of modulation wave command values of two phases, among the three-phase modulation wave command values, are greater than the prescribed value, the modulation wave operation unit stops switching of the two phases by saturating the modulation waves, to the maximum value of the absolute value of the carrier wave, by adding the operation amount to the modulation wave command values of the two phases.
