Automotive supercharging apparatus

Abstract: An electric motor-generator and an engine are linked using a first belt that is looped around a crank pulley that is mounted to a crank shaft and a one-way clutch pulley that is mounted to a rotating shaft. An electronic control unit drives the electric motor-generator as an electric motor and drives the compressor by the electric motor-generator if engine speed is less than or equal to a predetermined value.

Power converter and controller using such power converter for electric rolling stock

Abstract: Provided is a power converter having an inverter (13) wherein capacitors (12) are connected in parallel on a direct current side, and a power supply circuit configured to supply the inverter with a direct current from a power supply (1) and a power storage element (14). A controller using such power converter is also provided for electric rolling stocks. The power supply circuit is provided with a power supply switch (S1) arranged between the power supply and the inverter, a DCDC converter (15A) arranged between the power storage element and the inverter, and a bypass switch (S2) arranged between the power storage element and the inverter.

Electric power steering apparatus and control device integrated type electric motor

Abstract: An electric power steering apparatus and control device integrated-type electric motor includes an electric motor driving circuit constituted by a plurality of semiconductor power elements and controlling electric power supplied to an armature winding of an electric motor, a switch device for opening and closing a connection between an input terminal of the electric motor driving circuit and an external power source, and another switch device for opening and closing the armature winding, wherein at least one of both the switch devices is constituted by a semiconductor switch element, and the power elements and the semiconductor switch element are mounted on a board attached to a metallic case.

Wire rope flaw detector

Abstract: A wire rope flaw detector includes a magnetizer having a pair of exciting magnets disposed on a back yoke such that polarities thereof are opposite to each other, and forming a main magnetic path in a predetermined segment in an axial direction of a wire rope; and a leakage magnetic flux detection section disposed in the predetermined segment in the axial direction, and detecting leakage magnetic flux generated from a damaged portion of the wire rope. Each of the exciting magnets are formed so as to have a cross-section of a shape that embraces the wire rope when each exciting magnet is cut along a plane perpendicular to the axial direction of the wire rope, and has magnetic orientation, on the cross-section of the exciting magnet, oriented from at least two directions toward the wire rope.
