    摘要： A method of reinforcing a multiple optical fiber coupling unit is provided including the steps of removing a portion of longitudinal coatings of optical fibers of the multiple optical fiber coupling unit to expose glass portions of said optical fibers; fusing a portion of the exposed glass portions so as to optically couple the optical fibers; extending the fused portion to a predetermined state; fixing non-extended portions of the exposed glass portions on a first reinforcing substrate with a first adhesive; and fixing the first reinforcing substrate on a second reinforcing substrate with a second adhesive. The multiple optical fiber unit coupler made by this method has a transmission characteristic that does not substantially change even with a temperature change and under high humidity.

    摘要： The present invention provides a fiber coupler manufacturing apparatus comprising a pair of fiber holding portions and a fiber clamp disposed on each of the fiber holding portions for holding at least two optical fibers. A weight and pulley system is arranged wherein a first weight is coupled to each of the fiber holding portions to pull the fiber holding portions away from each other to apply tension to the optical fibers. A heating unit is disposed between the fiber holding portions and proximate to the optical fibers to heat the optical fibers. A second weight is coupled to either the fiber holding portions or the first weight and rests on a movable platform. As the movable platform descends in a vertical direction, the second weight applies additional force to the fiber holding portions and thus applies additional tension to the optical fibers.

    摘要： The invention provides a method for producing an optical-fiber coupler with a preset branching ratio. The present invention relates to a method in which part of a plurality of optical fibers are made to closely contact with each other so as to form a coupler. The coupler is heated to thereby obtain a predetermined branching ratio; the flow rate of a gas to be supplied to a heat source is increased/decreased by a quantity proportional to a difference between the drawing speed and a preset drawing speed while predetermined tension is applied to the optical fibers.

    摘要： Disclosed is a receptacle for use with a medical suction device which is equipped with a cover body and an external case for detachably holding and air-tightly surrounding the receptacle and a patient-side tube for introducing waste liquid into the receptacle, and designed to create a negative pressure in both an interior space of the cover body and the external case and an interior space of the receptacle so as to allow waste liquid to be sucked into the receptacle through the patient-side tube. The receptacle has an air-pervious/liquid-impervious element having air perviousness and liquid imperviousness. The air-pervious/liquid-impervious element at least partly constitutes a portion of the receptacle to be surrounded by the cover body and the external case.
