    摘要： Two T filters, one of which includes two resistive elements and one capacitive element and the other of which includes two capacitive elements and one resistive element, are inserted in a negative-feedback section of an operational amplifier, and a resistive element and a capacitive element are connected between each of intermediate nodes and a signal input terminal. A resistive element and a capacitive element which are connected to each other in parallel are connected between the signal input terminal and an inverting input terminal of the operational amplifier. With this configuration, overall admittances where elements connected to the corresponding intermediate nodes are in parallel connection are equal to each other.

    摘要： A rotating electric machine includes: a stator in which a stator coil is mounted to a plurality of slots formed on a stator core; and a rotor that is rotatably disposed inside the stator. A slot groove, having a predetermined depth and a predetermined width from an end face of the stator core and forming a space between the stator coil and the stator core, is formed around each of the plurality of slots. The stator coil includes a straight-shaped straight section which is inserted into the slot and is provided with an insulating material, and a coil end section which extends outside of the slot and is bent at a same height as the end face of the stator core.
