Abstract: In a motor-integrated electronic control device (2) of the present invention, a first connector (61) is provided at a first housing (81) on an opposite side to a motor (4), whereas a second connector (62) is provided at a second housing (82) on the motor (4) side, i.e. the first and second connectors (61, 62) are provided in different directions from each other, namely, that the first and second connectors (61, 62) are provided so as to face to mutually opposite directions. Therefore, a problem of intersection of electric signal of current flowing in electric circuit mounted on a first board (71) and electric signal of current flowing in electric circuit mounted on a second board (72) can be prevented. It is thus possible to suppress adverse effect on the electric circuit of the second board (72) by electric noise generated in the electric circuit of the first board (71).

Abstract: A grizzly apparatus includes a plurality of grizzly bars arranged at predetermined intervals in a second direction perpendicular to a first direction which is an extension direction of center axes of the grizzly bars. Each of the plurality of grizzly bars is rotatable in a direction opposite to a direction of rotation of its adjacent grizzly bar so that a slit through which a screening target object passes and a gap through which the screening target object does not pass alternately emerge, between adjacent grizzly bars. The guide includes an outer member forming its outer shape, and has at least one guide surface inclined with respect to the second direction in such a way that the guide surface descends as the guide surface advances in the second direction toward the slit to guide the screening target object having fallen onto the guide to the slit.

Abstract: In related art technique, an average neutral point voltage is detected via a low-pass filter. Time constant of the low-pass filter must be set to cover the entire output frequency band of an inverter and voltage fluctuation due to modulated signal must be separated from that due to a short circuit to ground. According to the present invention, whether abnormality such as a short circuit to ground or to supply occurs in output lines can be determined based on an actual neutral point voltage of a motor, which changes in a stepwise fashion in conformity to a PWM pulse pattern output by an inverter device, and a normal neutral point voltage which depends on a PWM pattern output by the inverter device. Highly reliable abnormality detection in accordance with the waveform of the neutral point voltage and stable abnormality detection not depending on the inverter output frequency are feasible.
