摘要： The present invention relates to a controllable constant flow regulating lift valve of a direct-acting automat ic control type that operates on an operating force derived from the condition of a working fluid, such as valve-inlet pressure prevailing in the inlet passage, valve-outlet pressure prevailing in the outlet passage, variation of liquid level on the side of the outlet and so on. The flow regulating valve comprises a flow regulating valve structure and a slide valve structure for automatic flow restriction control. In the controllable constant flow regulating lift valve, axial thrust acting on the spindle of a lift valve type flow regulating valve structure is balanced such that the constant flow regulating lift valve can be operated for constant flow regulation by a very small power. When the flow regulating valve structure and/or the slide valve structure are clogged with soil, sand and dirt, the internal pressure changes to open the clogged valve for automatic cleaning operation so that the soil, sand and dirt are washed away. This constant flow regulating lift valve is suitably applicable to a variety of industrial fields.

摘要： Optical fibers are fixed to elongating tables by optical fiber fixing jigs. Coatings are removed from portions of the fibers and respective fibers of two different groups are placed into tight contact with one another. Rectifier rods, supported movably by rectifier rod supporting members, are disposed outside the optical fiber strands. The fibers are then heated by a gas burner 4A so as to be welded integrally with each other, and are then elongated. By using rectifier rods, the outside optical fiber strands of the groups being welded are not so strongly heated that uniform welding and elongation can be realized. In one preferred embodiment, the fibers are arranged such that there are gaps therebetween. These gaps are substantially 250 .mu.m. The gaps are sufficiently wide that heating gas flows in a manner such that all the optical fiber strands are heated uniformly to make it possible uniform welding and elongation.
