摘要： PROBLEM TO BE SOLVED: To provide a permanent magnet generator type igniter capable of surely preventing ignition of an engine when rotation of the engine is reversed regardless of a rotary position of a rotor. SOLUTION: AC voltage having positive-negative polarity is generated in a power generation coil 14 by rotating the rotor 11 of a permanent magnet generator 10. The rotor 11 has projections 12 and 13 separating in the rotational direction, and arranged on the outer periphery. The projection 13 is longer in the rotational directional length than the projection 12. When the rotor 11 normally rotates, a rotation sensor 20 detects the projections 12 and 13 in a range of positive voltage on output voltage of the power generation coil 14, and a detecting signal of the rotation sensor 20 becomes effective in an AND circuit 30. When the rotor 11 reversely rotates, the rotation sensor 20 detects the projections 12 and 13 in a range of negative voltage on the output voltage of the power generation coil 14. At this time, the detecting signal of the rotation sensor 20 is invalidated by the AND circuit 30.

摘要： PROBLEM TO BE SOLVED: To provide a technology capable of keeping an occupant of another vehicle, which appears suddenly, from being dazzled by appropriately controlling irradiation of light from a headlamp device even in a poor-visibility environment.SOLUTION: A control unit that controls a headlamp device uses a luminance sensor to repeatedly execute processing of measuring the brightness in front of an own vehicle. For example, when a curved road region is present forward the own vehicle, the brightness of a road surface or guardrail in a specific area (an area to which light is irradiated from a headlamp device of a preceding vehicle) within the road region is measured. A change quantity Δ of the measured value of the brightness from a previous measured value is calculated (S160). If the change quantity Δ is equal to or larger than a threshold TH (Yes at S170), a vehicle that has not appeared in a forward visual field of the own vehicle is foreseen to emerge (S180), and an irradiation mode of the light from the headlamp device is switched from one to another in order to darken the emergence area (S185, 190, and 195).

摘要： PROBLEM TO BE SOLVED: To eliminate generation of luminous intensity distribution split phenomenon wherein an irradiation range thereof almost disappears on the front road surface in preceding swivel control by front road information relative to one of left and right head lights (head lamps) and swivel control by steering of a driver relative to the other.
SOLUTION: During swivel preceding control of one of the left and right head lights based on a presumption swivel control angle ESWC by a vehicle speed SPD and the front road information DNAVI, when it is determined that the steering of a steering wheel by the driver exists (S107) and the swivel direction is a reverse direction (S109), the swivel control angle SWC is made preferential and the presumption swivel control angle ESWC is guard-processed by a predetermined amount α (S111). Therefore, no delay of swivel control of the left and right head lights relative to the traveling condition of the vehicle and the front road condition is generated and the luminous intensity distribution split phenomenon is not generated even if the front road is a strong (swinging radius of curvature is small) S shape road. Front visibility of the driver can be ensured.

摘要： PROBLEM TO BE SOLVED: To certainly eliminate the influence of external electric wave noise superimposed on a wiring unit and to improve the detection accuracy of gas concentration. SOLUTION: A case A made of conductive material at ground potential is divided into two chambers with a partition plate 52 similarly made of conductive material at ground potential. A sensor control circuit board 33 and wiring connection board 34 for constituting sensor control units 10 are stored in the two chambers, respectively. The sensor control circuit board 33 is electrically connected to the wiring connection board 34 via a feedthrough capacitor 35 arranged in the partition plate 52. Thanks to such a constitution, even if an external electric wave noise superimposed on the wiring connection substrate 34 occurs, this is absorbed by the feedthrough capacitor 35 and hence the influence of the noise to the sensor control circuit board 33 can be eliminated.

摘要： PROBLEM TO BE SOLVED: To provide an ignition device for an internal combustion engine reducing power consumption of a battery and improving starting performance of an engine. SOLUTION: Since a switching transistor 21 is connected in parallel with a regulator Zener diode 23, by turning on the switching transistor 21 at low speed rotation of the engine, the charging voltage of an ignition capacitor 17 is regulated only by the regulator Zener diode 23, and the power consumption of the battery 10 is reduced by shortening an oscillating period of a DC/DC converter 11. Therefore, even if electric power supplied to the ignition device is lowered than usual due to deterioration of the battery 10 and the like, a discharged current required for igniting the engine can be obtained, and starting performance can be improved by enhancing ignition performance of the engine. The switching transistor 21 is turned off at middle/high speed rotation of the engine, and the oscillating period of the DC/DC converter 11 is made to be long, thereby corresponding to required voltage at the middle/high speed rotation of the engine.
