A connection device includes a connector provided with wire insertion holes receiving end portions of electrical wires and terminal fittings connected to the end portions. The electrical wires include a lead wire and a dummy wire. One end of the lead wire is inserted in the wire insertion holes while another end of the lead wire is connected to another connector. One end and another end of the dummy wire are inserted in empty ones of the wire insertion holes. A protective tube, which is shorter than the lead wire, is provided between the connector and the other connector, so as to extend over an entire length of the lead wire except opposite end portions of the lead wire and so as to cover the lead wire and the dummy wire. A U-shaped curved end portion of the dummy wire is exposed from an end portion of the protective tube.

A method of annealing a metal member includes: disposing a first heater in an inner space of a hollow cylindrical metal member having an inner peripheral surface provided with plural teeth protruding toward a central direction, the first heater radiating infrared light and being disposed so as to extend parallel to a direction of a central axis of the metal member; heating the metal member from the inner space with the first heater; and gradually cooling the metal member after heating.

There is provided a hybrid vehicle comprising a mode selection device configured to select one drive mode among a plurality of drive modes according to a user's operation. The plurality of drive modes include a first drive mode in which the hybrid vehicle is driven with power from a motor with stopping rotation of an engine and a second drive mode in which the hybrid vehicle is driven with rotation of the engine. On satisfaction of filter regeneration conditions that an accumulated amount of particulate matter accumulated on a filter is equal to or greater than a predetermined accumulated amount and that a temperature of the filter is equal to or higher than a predetermined temperature, the hybrid vehicle is driven in the second drive mode even when the first drive mode is selected by the mode selection device.

A method of manufacturing a laminated stator core and a laminated stator core manufactured by the method, the method capable of forming a recessover one or both of (a) a lateral portion of an ear piece C of the stator core sheet A to be formed adjacent to the stator core sheet B and (b) a peripheral portion of the annular yoke piece D continuing to the lateral portion, the peripheral portion beside the ear piece C; fitting one ear piece E of the stator core sheet B with a gap in the recess; and thereby improving a material yield when the stator core sheetsare formed from the strip material

The start control is repeatedly performed for an oil pump that pressure feeds the flow of oil in a motor cooling system. This control is repeated for every specified rise in motor temperature (e.g., every 10&#xb0; C.) from an initial starting temperature. This arrangement increases the potential for a successful start-up of the oil pump even when the oil has a high viscosity due to a relatively low outside air temperature. In the event of a failed start-up of the oil pump by repeated starting, the start control determines an abnormality exists in the oil pump or its power supply if an outside air temperature is greater than a reference temperature. This arrangement effectively eliminates incorrect detection of an abnormality in the oil pump or its power supply.

An internal combustion engine start controller in a vehicle that includes: a power source; an internal combustion engine that is started by using electric power supplied from the power source; a first motor; and a first electric power converter that is constructed so as to be able to perform electric power conversion between the power source and the first motor through switching control of power semiconductor elements is provided. The start controller includes: a start detecting device for detecting whether the engine is in a starting operation; and a first frequency setting device that, when the engine is in a starting operation, sets a switching frequency of the first electric power converter to a frequency lower than that used when the engine is not in a starting operation.
