Abstract: A vehicular headlamp apparatus includes: a headlamp that illuminates ahead of a vehicle; light distribution pattern switching means for switching light distribution pattern of the headlamp between a plurality of light distribution patterns which include, at least, a high beam and a low beam; detecting means for detecting a forward vehicle present in front of the vehicle; controlling means for controlling the light distribution pattern switching means based on a detection result of the detecting means; and turning radius acquiring means for acquiring a turning radius of the own vehicle during running. Moreover, when the turning radius of the own vehicle acquired by the turning radius acquiring means is less than a predetermined value, the controlling means inhibits the switching of the light distribution pattern of the headlamp to a higher side.

Abstract: A vehicular headlamp apparatus includes: a headlamp that illuminates ahead of a vehicle; illumination range changing means for changing an illumination range of the headlamp; detecting means for detecting a position of a forward vehicle present in front of the vehicle; controlling means for controlling the illumination range changing means based on the position of the forward vehicle detected by the detecting means; and determining means for determining whether or not the position of the forward vehicle is within the illumination range.

Abstract: A parking mode selection apparatus selects one parking mode among from plural parking modes including at least a perpendicular parking or a parallel parking. The parking mode selection apparatus includes a steer angle detector that detects a steer angle of a steering wheel, an operation detector that detects, based on the steer angle detected by the steer angle detector, a predetermined operation in which the steering wheel is returned to a neutral position after rotated to a right or a left, and a parking mode selector. The parking mode selector selects, when the predetermined operation is detected by the operation detector, a parking mode that coincides with a steered direction to the right or the left of the steer angle detected by the steer angle detector and is associated with said steer angle.

Abstract: A distribution pattern of the vehicle headlight is transitioned according to a vehicle speed, between three light distribution patterns. The patterns are a normal mode corresponding to a light distribution variable control state, an OFF mode corresponding to a low-beam state, and a residential mode corresponding to a high-beam light distribution that does not give a glare to pedestrians. It is determined whether or not a detected vehicle speed is within a predetermined range that enables transition of the light distribution pattern to the residential mode, and it is determined whether or not an immediately-preceding execution state of the light distribution pattern has been the normal mode. Transition between modes of the light distribution pattern is prohibited when a detected vehicle speed is determined to be within a predetermined range, and the immediately-preceding execution state is determined to have been the normal mode.

Abstract: In a vehicle headlamp light distribution control system which changes a shaded range so as to track a position of a forward vehicle and terminates the tracking when the forward vehicle moves away from the front of a system-mounted vehicle by a tracking limit, how right and left margins of the shaded range for a tracking lag and the tracking limit is determined is arranged to realize adequate dazzle and improve the visibility to a driver of the system-mounted vehicle. It is determined whether the forward vehicle is a preceding vehicle or an oncoming vehicle. When the forward vehicle is the preceding vehicle, optical axis control margins that are right and left margins for the shaded range for the tracking lag are set to be smaller than those when the forward vehicle is the oncoming vehicle to widen the maximum shading range according to the tracking limit.

Abstract: In a stick coil, there is disclosed an ignition coil for an internal combustion engine which can prevent a crack (a collar leak) from being generated due to a thermal stress. In this ignition coil, the structure is made such that a size (L) of a portion which is in parallel to an axial direction of a primary spool (121) in a projection portion (121b) is larger than a size (T) of a portion which is in parallel to an orthogonal direction to the axial direction of the primary spool (121). Accordingly, a frontal projected area of the projection portion (121b) as seen from a flowing direction of a resin becomes small, a resin flow is hard to get out of order at a time when the resin flows through a portion corresponding to the projection portion (121b) at the forming time, and a convoluted void and a weld are hard to be generated.

Abstract: A gliding board has a core structure (11) constructed by bonding flat plates (14, 15) to top and bottom surfaces of a core member (13) of the shape of a rectangular or trapezoidal waveform waving forwardly and rearwardly in the longitudinal direction of the board. The gliding board has a similar longitudinal bending rigidity compared to those of the conventional gliding boards, a relatively small longitudinal torsional/bending rigidity ratio and a high lateral bending rigidity.
