Abstract: In order to reduce a junction leakage current and obtain a shallow junction, ion implantation to form a doped region, such as an active region of a transistor, is followed by a low-temperature annealing and pulsed laser irradiation. The annealing temperature and time of the low-temperature anneal are 600.degree. C. and one hour, for example. The subsequent pulsed laser irradiation is performed by a XeCl laser, for example, with irradiation energy of 700 mJ/cm2, and a pulse width of 44 nsec. This process can reduce the leakage current by effectively removing points defects around the junction, and enables activation without increasing the depth of the junction.

Abstract: A vehicular headlamp assembly with a tilt measuring device of small height, which is difficult to damage, requires a decreased number of parts, and is easy to assemble. The tilt measuring device is interposed between a protruding portion of a horizontal aiming screw protruding rearward of a reference member and the reference member. The tilt measuring device includes a fixed holder fixed to the reference member and covering the protruding portion of the horizontal aiming screw protruding rearward of the reference member, an elongated groove being formed in said fixed holder extending parallel to the horizontal aiming screw. A slidable nut member is received in the fixed holder in such a manner as to be longitudinally slidable relative to the fixed holder. The nut member threadedly engages the protruding portion of the horizontal aiming screw. A portion of the nut member is exposed through the elongated groove of the fixed holder.

Abstract: An aiming level device for a motor vehicle headlamp which has a short longitudinal length, requires a small number of components, and is simple to assemble. The inventive aiming level device includes a body member or base, a bubble vial supporting frame pivotable with respect to the body member, and a zero-point adjusting screw for holding a sideward extending part of the supporting frame. The bubble vial supporting frame, which is formed by cutting and bending a single thin metal plate, holds the bubble vial with parts continuously formed at a side region of the front-rear extending region of the frame to support the bubble vial at front and rear portions thereof, and the front and rear end portions of the front-rear extending region are held by the zero-point adjusting screw so that it is adjustable upward and downward by rotating the screw.
