A non-contact power supply system supplies electric power in a non-contact manner from a power transmission device to a vehicle. The power transmission device includes an impedance adjusting unit configured to adjust an impedance between a power supply unit and a power transmission unit. A vehicle ECU assists an alignment between the power transmission unit and the power receiving unit in the parking operation based on a power transmission efficiency between the power transmission unit and the power receiving unit. A power transmission ECU, at the time of the alignment in the parking operation, controls the impedance adjusting unit based on a distance between the power transmission unit and the power receiving unit in a vertical direction (vehicle height). Accordingly, lowering of the power transmission efficiency caused by a change in an impedance along with a change in the vehicle height can be suppressed.

A non-contact power transmission apparatus includes a high-frequency converting section, which converts input voltage to high-frequency voltage and outputs it, a primary coil, which receives high-frequency voltage from the high-frequency converting section, and a secondary coil, which receives electric power from the primary coil. The non-contact power transmission apparatus further includes a load to which the electric power received by the secondary coil is supplied, a rectifier located between the secondary coil and the load, and an output adjusting section, which supplies, as pulses, output voltage to the high-frequency converting section. The output adjusting section is configured to increase or reduce output to the load by adjusting a duty cycle of the pulse output.

A contactless power transmission device is provided with an AC power source, a primary coil, a secondary coil, an electric component and a power factor calculation unit. The primary coil is supplied with AC power from the AC power source. The secondary coil is allowed to receive AC power from the primary coil. The electric component is supplied with the AC power that is received by the secondary coil. The power factor calculation unit calculates at least either the power factor with respect to the load from the output of the AC power source to the electric component, or the power factor with respect to the load from the output of the secondary coil to the electric component.

When a mobile unit moves with a motor driven by electric power supplied by a power supply line without a contact when the mobile unit moves where the power supply line exists. The electric power supplied without a contact is also used in charging a electric double layer capacitor. Since the charging current is limited by limiting resistance, the motor can be supplied with sufficient power although the electric double layer capacitor is in a vacant (completely discharged) state.

A dog clutch construction is provided for selectively rotationally connecting or disconnecting two coaxially arranged shafts. The dog clutch includes teeth on each shaft which are axially juxtaposed to each other. A toothed sleeve is engaged over the teeth. The sleeve is axially movable from a first position located on only one set of teeth to a second position located on both sets of teeth. A new meshing process is provided for meshing the teeth of the sleeve with the other two sets of teeth. A means for axially driving the sleeve from the first position to the second position is also provided, including an annular power piston positioned coaxially with the sleeve and a mechanism for transmitting the driving movement of the piston to the sleeve. The mechanism for tansmitting the driving movement is also annular and uniformly engaging around the sleeve and incorporates an axial resiliency to soften the driving action of the piston particularly at the instant of the meshing of the teeth of the sleeve with the other two sets of teeth, while ensuring uniform driving of the sleeve over all peripheral portions thereof.

A pivotal member 2a comprises a main member 19 having inner and outer peripheral faces formed axially symmetric, an auxiliary member 20 having an inner peripheral face 23 made eccentric with respect to an outer peripheral face 24, such that the main member 19 is pivotally supported on the outer peripheral face of a fixed shaft 1, and a tension pulley 5 supported so as to be freely rotatable, on the outer peripheral face of the auxiliary member 20, thereby simplifying manufacturing operations for a pivotal member 2a of an auto tensioner to reduce the manufactured cost.

In an overdrive planetary gear unit of an automatic transmission, a helical planetary pinion has its front portion cut to form an cutout portion and to have an axial-direction cross section asymmetrical in the direction of its rotation axis in order to uniformize, in the axial direction, the load imposed upon a bearing disposed around the circumference of the pinion shaft.In a front planetary gear unit of a main transmission of the automatic transmission, a helical planetary pinion has its rear portion cut to form an cutout portion and to have an axial-direction cross section asymmetrical in the direction of its rotation axis in order to uniformize the load imposed upon a bearing disposed around the circumference of the pinion shaft.It is thereby possible to reduce the weight of each planetary pinion and, hence, the centrifugal force acting on the pinion. In the overdrive planetary gear unit, the center of gravity of the planetary pinion is shifted toward the rear end of the pinion, and the centrifugal force acting on this pinion is therefore smaller at the front end, thereby reducing the load imposed on the bearing at the front end. In the front planetary pinion gear unit of the main transmission unit, the center of gravity of the planetary pinion is shifted toward the front end, and the centrifugal force is therefore smaller at the rear end, thereby reducing the load imposed on the bearing at the rear end. The non-uniformity of the load on each bearing in the axial direction is thereby reduced.
