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.

A lamp socket assembly for an automotive headlamp, wherein a mount is formed at the back of the headlamp reflector. A socket fixture is screwed to the reflector at a rear surface of the lamp. The mount has a plurality of partial circumferential depressions. The socket fixture has corresponding cuts about its central hole. However, the cuts extend over only a portion of the depressions. A lamp has an integral socket with a focal point plate having a plurality of radially extending tongues. The tongues can be inserted through the cuts into the depressions and be engaged therein. In a dual lamp unit, one of the depressions of the mount for the auxiliary lamp can have a protrusion not present in the main lamp. The tongues for the main and auxiliary lamp sockets differ so that the main lamp socket cannot be engaged with the mount for the auxiliary lamp.

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 cloth for ink jet printing, fabricated by providing a low density cloth with a sizing agent of the gel-transition type, gel-initiating agent, and ink receiving agent for filling up gaps between fibers, and by drying the low density cloth so that even in the case where the ink-jet printing process is applied to such a low density cloth as a loosely woven or knitted fabric, a clear image can be printed thereon without ink striking through gaps between fibers, and without causing the cloth to be stained. For the low density cloth, a cloth of a single yarn weight fineness of 100 d or less, and a woven or knitted fabric of a warp density of 120 warps or less/inch or a filling density of 150 fillings or less/inch are suitable. With the use of the cloth, an ink-jet printed fabric deep in color as well as abundantly expressive of gradation (that is, having a wide range of color strength) can be obtained while preventing ink from passing through, and supporting members and the cloth from being stained.

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 vehicular headlamp employing a discharge bulb as a light source in which a lighting circuit for the bulb, including an ignitor, is secured to a lamp housing in such a manner as to cover a rear opening in the housing. This arrangement results in significantly reduced danger of shock and reduced radiation of electromagnetic noise. In another embodiment of the invention, a lighting-circuit-accommodating unit containing a lighting circuit is bayonet-engaged with a circular opening in the rear wall of a lamp body, and also is fixed to the lamp body by a second fixing device in such a manner as to prevent rotation of the lighting-circuit-accommodating unit relative to the lamp body.

An internal combustion engine for a small planing boat for reducing the lateral width of an oil pan in conformity to the configuration of the bottom while securing the filtering surface area of an oil strainer. In addition, a vertical width of the oil pan is maintained to be small to thereby lower the total height of the internal combustion engine. In an internal combustion engine for a small planing boat, an oil pan is provided at the bottom portion of the internal combustion engine with an oil passage for communicating with an oil pump being formed inside the oil pan. A vertical wall of the oil passage is partially cut away to form communication openings each communicating between the inside and outside of the oil passage with the oil strainers being interposed in the communication openings substantially vertically to divide the oil passage into inside and outside.

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.
