Abstract: A motor driving device includes an inverter circuit having switching elements; and a control device controlling the switching of the switching elements. The control device sets a carrier frequency to f1 when a two-phase modulation scheme is selected, and sets the carrier frequency to f0, which is half of the carrier frequency f1, when a three-phase modulation scheme is selected. Thereby, the frequency of the secondary component of a current flowing in a filter circuit of when selecting the three-phase modulation scheme may be deviated from the resonance frequency of the filter circuit. Accordingly, the current ripple generated in the filter circuit may be reduced even when selectively switching the modulation scheme for the PWM modulation among a plurality of modulation schemes.

Abstract: A method for separating solvent-containing water, which is generated in the process for producing an ashless coal, into a solvent and water readily without using any adsorbent or the like (a solvent separation method). The solvent separation method comprises: a solvent-containing water supply step of supplying the solvent-containing water into a pressure vessel for solvent separation purposes; and a temperature retention step of retaining the temperature of the solvent-containing water that has been supplied into the pressure vessel for solvent separation purposes at a predetermined temperature (e.g., 100 to 180 DEG C. inclusive). In the pressure vessel for solvent separation purposes, water in the liquid form moves downward and the solvent moves upward due to the difference between the density of water and the density of the solvent at the predetermined temperature. In this manner, the solvent-containing water can be separated into the solvent and water.

Abstract: Provided is an ash-free coal production method without the need to once re-liquefy and form an ash-free coal. The ash-free coal production method includes an extraction step of mixing coal with a solvent to prepare a slurry and heating the slurry to extract a solvent-soluble coal component; a separation step of separating a solution containing the solvent-soluble coal component from the slurry obtained from the extraction step; an ash-free coal obtaining step of evaporatively separating the solvent from the solution separated in the separation step to obtain an ash-free coal. The ash-free coal obtaining step in the production method is performed so that the solvent is evaporatively separated from the solution to give a liquid ash-free coal, and the liquid ash-free coal is brought into contact with a solidifier (e.g., water) to solidify into a predetermined shape.

Abstract: Provided is a meted that controls and uniformizes fluidity of ash-free coal. The method includes the steps of obtaining an ash-free coal by removing a solvent from a solution containing a coal component dissolved therein (ash-free coal obtaining step (solvent recovering unit 8)); and mixing a plurality of coals of different types or components theme where the coals are capable of individually giving ash-free coals having different fluidities (mixing step (see reference signs B1 to B6)). The ash-free coal obtaining step (solvent recovering unit 8) obtains the ash-free coal by removing the solvent from the solution containing components of the coals which have been mixed.

Abstract: Provided is an ash-free coal production method that can produce an ash-free coal efficiently with a higher solvent recovery rate. The ash-free coal production method includes an extraction step of mixing coal with a solvent to give a slurry and heating the slurry to extract a solvent-soluble coal component; a separation step of separating a solution containing the coal component from the slurry containing the extracted coal component; and an ash-free coal obtaining step of separating and recovering the solvent from the separated solution to give an ash-free coal. The ash-free coal obtaining step includes a pressure-reducing substep of reducing a pressure to a level lower than the solvent vapor pressure to evaporatively separate the solvent from the solution to thereby give a solid ash-free coal; and a heating substep of heating the solid ash-free coal to evaporatively separate a residual solvent from the ash-free coal.

Abstract: An inverter circuit for a motor outputs three-phase AC currents, which are outputted from common connection points to stator coils, based on output voltage of a DC power source and a power supply capacitor by a switching operation of transistors. An inverter control circuit determines that a system main relay is turned off, upon receiving a main relay-off signal from an electronic control unit. The inverter control circuit turns on the low-side transistors, while turning off the high-side transistors. A discharge current flows from the positive electrode to the negative electrode of the power supply capacitor through the stator coil and the low-side transistors, so that electric charge stored in the power supply capacitor is discharged.
