ELECTRIC MOTOR COOLING APPARATUS (18183526)

Abstract

An electric motor cooling apparatus applied to an electric motor mounted as a driving force source on a vehicle. The electric motor has a stator core and a stator coil wound around the stator core, the electric motor cooling apparatus ejects coolant toward the stator coil. The electric motor cooling apparatus comprises a cooling pipe disposed above the electric motor in direction of a vertical line in on-vehicle state. The cooling pipe has an ejection aperture from which the coolant is ejected. The electric motor cooling apparatus comprises an acceleration information acquisition part detecting or estimating acceleration information of the vehicle and a coolant flowrate regulation part regulating flowrate of the coolant supplied into the cooling pipe. The ejection aperture of the cooling pipe is formed to enable adjustment of ejection direction of the coolant ejected from the ejection aperture, depending on the flowrate of the coolant.

METHOD AND APPARATUS FOR MANUFACTURING STATOR (18188896)

Abstract

A method of manufacturing a stator that includes a tubular-shaped stator core and a tubular-shaped coil. The method includes: (a) a holding step of holding an insulation sheet, which is disposed in a slot provided in the stator core, by causing a pressing device to press the insulation sheet against an inner surface of the slot in an axial end potion of the stator core; (b) an inserting step of inserting a segment portion of the coil to an inside of the insulation sheet from a side of the axial end potion of the stator core, in a position distant from the pressing device that presses the insulation sheet against the inner surface of the slot; and (c) a retracting step of retracting the pressing device by extracting the pressing device from the slot, after the inserting step. Also disclosed is an apparatus for manufacturing the stator.

INSULATED COMMUNICATION SYSTEM (18187123)

Abstract

An insulated communication system includes a communication controller that sets communication data to a communication symbol through a numeral system and executes insulated communication through an insulator by adopting the communication symbol. The numeral system includes multiple states having a positive state, a negative state and a zero state. The positive state is represented by at least one positive integer, and the negative state is represented by at least one negative integer. The zero state is represented by zero being a level without generating current consumption. An absolute value of the at least one positive integer and an absolute value of the at least one negative integer are identical to each other. The communication controller sets an initial section of the communication data in the communication symbol to the positive state or the negative state, and sets a following section of the communication data to one of the multiple states.
