Abstract: A method for manufacturing a coil that is formed by winding a conductor in a loop shape and stacking loops of the conductor and that includes a slot placement portion to be placed in a slot of a stator core, and a coil end placement portion to be placed outside the slot. The method preferably involves a winding step, a protrusion forming step, a crank forming step, an opening step, and an arc forming step. The winding step forms a winding having slot placement and coil end placement portions. The protrusion forming step forms a protruding shape that protrudes in a radially outward direction of the winding. In the crank forming step a stepped portion. The opening step of forming the winding so that an interval between the pair of expected slot placement portions gradually increases. The arc forming step forms an arc-shaped portion curved in the stacking direction.

Abstract: A pitch angle in the back-and-forth direction of the vehicle body is calculated based on output signals of height sensors disposed at front and rear wheels of the vehicle. A vehicle traveling speed is obtained. A vehicle acceleration is obtained from the vehicle traveling speed. Using the vehicle traveling speed and the vehicle acceleration, a judgement is made to determine the control mode corresponding to the vehicle traveling condition, by selecting one from the group consisting of a stopping mode, an acceleration mode, a deceleration mode and a constant-speed mode. An actuator target value (i.e., target aiming adjustment angle) is calculated in accordance with the determined control mode. To obtain this actuator target value, a filter is used to process the pitch angle so that the headlights do not dazzle an oncoming vehicle's driver. Then, the aiming adjustment for the headlights is performed by actuating actuators in accordance with the actuator target value.
