<p><P>PROBLEM TO BE SOLVED: To enhance pressing force against a photocurable resin-impregnated tube, and to prevent damage of the end of the photocurable resin-impregnated tube in a reversed position of a lamp train in vertical movement of the lamp train in a branch pipe. <P>SOLUTION: When the resin-impregnated tube is at its maximum volume level (maximum protrusion setting position in the branch pipe of the resin-impregnated tube), gas in the tube is forced to leak out into the branch pipe, thereby preventing expansion of the resin-impregnated tube beyond its set maximum volume level. The pressing force against the photocurable resin-impregnated tube is applied by press-contacting the end of a leg piece of the lamp train against the photocurable type resin-impregnated tube when the lamp train moves up and down in the branch pipe. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
