    • An automotive headlamp employing a discharge lamp as its light source in which the emission of harmful ultraviolet ray is eliminated in the output light beam. The headlamp includes a lamp body, a reflector mounted in the lamp body, and a discharge bulb mounted in a bulb insertion hole in the rear portion of the reflector. The discharge bulb is composed of a lamp base, a pair of long and short lead supports projecting forward from the lamp base, the discharge lamp, a pair of lead wires extending in respective forward and rearward directions from front and rear end portions of the discharge lamp, and forward and rear metal supports welded to the long and short lead supports and to respective ones of the lead wires so as to support the discharge lamp at its opposite ends on the long and short lead supports. The forward end of the longer lead support terminates at a position substantially corresponding to a front end edge of the front portion of the discharge lamp. An ultraviolet-ray shielding globe encloses the discharge lamp so as to cut ultraviolet rays from light emitted by the discharge lamp. A front end portion of the ultraviolet-ray shielding globe is tapered so as not to interfere with light reflected from a circumferential edge portion of the reflector around the bulb insertion hole.

    • A water-jet pump includes a cylindrical housing and an impeller. The impeller is disposed in the cylindrical housing and is configured to be rotated in a rotating direction. The impeller includes a shaft body and plural blades. The plural blades are provided on an outer circumference of the shaft body. A front portion of one of the plural blades overlaps a rear portion of another of the plural blades adjacent to one of the plural blades when viewed in an axial direction of the shaft body. When viewed in the axial direction, at least a part of a rear edge of the rear portion is formed obliquely with respect to a radial direction of the impeller towards the rotating direction. A cutaway portion is formed in each of the plural blades between at least a part of the rear edge and the outer circumference.

    • A discharge lamp system, particularly for vehicular headlamp applications, broadly comprises a discharge lamp assembly and a lighting circuit assembly. The discharge lamp assembly comprises a discharge lamp unit, and a lamp carrier subassembly mechanically supporting the discharge lamp unit and electrically connected thereto. The lighting circuit assembly comprises an electric lighting circuit mounted within a housing or housings for causing the discharge lamp unit to glow by an electric discharge. The discharge lamp assembly and the lighting circuit assembly are directly interconnected both mechanically and electrically, in order to dispense with cables or cords that have been conventionally used for their electrical interconnection.

    • A vehicle headlamp system with headlamps, each of which contains a lamp unit for emitting beams forward with a predetermined luminous intensity distribution. The system carries out beam emission with a luminous intensity distribution corresponding to the travel conditions of a vehicle. In an implementation, when the speed of one's own vehicle exceeds 25 km/h, a low-beam luminous intensity distribution P(L) is varied according to a vehicle-to-vehicle distance in relation to a preceding vehicle. Remote visibility is increased by positioning a cut-off line slightly upward when the vehicle-to-vehicle distance L is long, whereas when the vehicle-to-vehicle distance L is short the cut-off line is lowered slightly in order not to give a glare to the driver of the preceding vehicle. But when the vehicle speed V is 25 km/h or lower, the low-beam luminous intensity distribution P(L) is fixed at a downward position which prevents glare and prevents an unpleasant feeling that something is wrong from being given to the driver of the preceding vehicle resulting from the change of the low-beam luminous intensity distribution P(L).
