Title: Production of large-diameter thick-walled bent pipe
Inventor: SAKAIYAMA KOUZOU
IPC: B21D7/00
Filed: 1978-07-10
Abstract: PURPOSE: To produce large-diameter thick-walled bent pipes through bending of ordinary methods by forming the wall thickness on the outer side of bending of a blank pipe to be bent larger than that of the inner side.  
     CONSTITUTION: A blank pipe P is fabricated to an inside diameter of d'=d-2c 1 . Thereafter, the inside diameter of the portion which receives bending is made eccentric and so fabricated that the wall thickness on the outer side of bending becomes t+c 1  and that of the inner side of bending t-c 2 . The neck part n is so fabricated that its inside diameter d becomes d=D-2t. C 1  is the thickness decreased by bending and C 2  likewise the thickness increased by bending. Deviating the blank pipe P in wall thickness in this way and bending the same by ordinary methods enable the elbow E of an equal wall thickness over the entire part, i.e., thickness t to be produced. If the wall thicknesses are deviated, the rate of thickness reduction is smaller and the rate of thickness increase larger than those on bending of an equal thickness pipe, and therefore in the case of embodiment, C 1  and C 2  are determined by considering this. C 1  and C 2  may be readily calculated if the heating temperature at the fabrication and other bending conditions are determined.

Filed: 1988-04-05
Abstract: PURPOSE:To enable a sufficient irradiation of the light from a sub-light source to the front without providing any exclusive reflector and miniaturize the whole form/by positioning the opening flange on the sub-light source side of a main reflector so that it does not shield the luminating light from the sub-light source toward the part close to the front flange on the anti-sub-light source side. CONSTITUTION:When a clearance lamp bulb 24 is lighted, a part of the light emitted from said bulb is reflected toward the front by the reflection by the common part 5b of main reflector 5. Thus, even if the disposing part of the clearance lamp bulb 24, or a clearance lamp reflector 26 is not enlarged so much, a sufficient light can be emitted toward the front when the clearance lamp light source 24 is lighted. Hence, no reflector 26 or a small one, even if provided suffices the sub-light source 24, so that the whole form can be miniaturized, compared with the case in which the main light source 7 and sub-light source 24 are provided with reflectors 5, 26 for the exclusive uses, respectively.
