IPC: B23K9/073
Filed: 1990-04-17
Abstract: PURPOSE:To suppress penetration of base metals by repeating periodically four levels from a plus period to a minus period of an output current and supplying an electric current higher than a first level when the arc voltage drops below a specified value. CONSTITUTION:In consumable electrode gas shielded arc welding, the current higher than a critical current as an output level in a first period to make the wire polarity plus is supplied.

When the arc voltage drops below the specified value, the current of a fourth level higher than the first level is supplied to perform welding. It is desirable to increase or decrease the minus period of the electrode according to the feed quantity of the consumable electrode or increase/decrease of a set value of the arc voltage.

Filed: 1992-04-21
Abstract: PURPOSE:To provide a star coupler with its tapered part strength increased and establish a method of easily manufacturing such couplers by forming a tapered part on a part of a multi-core fiber cable consisting of optical fibers which are embedded in glass, and making photo-coupling of these optical fibers with each other. CONSTITUTION:A star coupler 1 is composed of a core 2, optical fibers 4 each having a core 2 and clad 3, and glass 5 as a support. Each each of this star coupler is formed in multi-core fiber where the optical fibers 4 are embedded in the glass support 5, and in the middle thereof a tapered part 6 is formed. The tapered part 6 is formed by ductilely stretching this multi-core fiber under heating, or by simultaneously applying a twine. This type of star coupler has a greater dia. in the stretched part than a conventional star coupler of melt attaching elongation type, so that it is stable against external force, and further because of this structure in which the whole tapered part is embedded in glass, there is no risk of changing the optical characteristics even though external force is applied to the star coupler, which is thus stable in mechanical and optical terms.
