摘要： A multiple control valve for operating a civil construction machine or the like comprises a valve body, at least two parallel direction change-over plungers assembled in the valve body, by-pass passages and fluid supply passages formed in the valve body and operatively communicated with the plungers for feeding fluid from an external source to the plungers. One of plungers disposed most downstream side of the multiple control valve is provided with inner passages arranged on both sides thereof, a passage crossing the plunger, an axial passage having one end closed and the other end opened towards one of the inner passages, and a lateral port communicated with the inner passage. The crossing passage is communicated with the axial passage at a portion near the closed end thereof. When the most downstream side plunger is displaced from its neutral position in a direction to operate a corresponding actuator for operating a mechanism of the machine in a predetermined direction, the crossing passage intercommunicates with one of the supply passage and the lateral port intercommunicates with the by-pass passage and when the most downstream side plunger and another plunger disposed upstream side thereof are simultaneously displaced in the direction described above, only the connection between the crossing passage and one of the supply passages is established.

摘要： A vehicular lamp includes a lamp source, a lamp body accommodating the lamp source, and a lens attached to the lamp body. The lamp body has an abutment surface on the top portion of a peripheral wall, which is configured to rise in a direction of an optical axis of the light source along a peripheral edge of the lamp body. The abutment surface of the lamp body is configured to incline to the optical axis. Similary, the lens has an abutment surface corresponding to the abutment surface of the lamp body along a peripheral portion of the lens. In this case, the abutment surface of the lens is configured within the dimention of an outer surface of the lens so as not to protrude over the outer surface. The abutment surfaces of the lamp body and the lens are integrally jointed together by laser walding.

摘要： In a lamp including a lamp housing and a lamp cover, the lamp cover is laser-beam welded to an opening edge portion of the lamp housing. There exists no trace of fusion on the opening edge portion of the lamp housing in any other areas than a surfaces abutment portion where the lamp cover is brought into abutment. A method for fabricating a lamp includes bringing a lamp cover into abutment with an opening edge portion of a lamp housing; and emitting a laser beam to a surfaces abutment portion of the lamp housing with the lamp cover so as to laser-beam weld the lamp housing and the lamp cover together. The emission of the laser beam is implemented while blocking the laser beam so that the laser beam is not emitted to at least any other areas of the opening edge portion than the surfaces abutment portion. An apparatus for fabricating a lamp includes support means for rotatably supporting a lamp housing and a lamp cover that is brought into abutment with an opening edge portion of the lamp housing in an abutment state; laser beam emitting means for emitting a laser beam to a surfaces abutment portion of the opening edge portion where the lamp housing is in abutment with the lamp cover; and laser beam blocking means for blocking the emission of a laser beam to at least any other areas of the opening edge portion than the surfaces abutment portion.
