    摘要: An optical fiber coupler for optical fiber amplifier use in the field of optical communications is provided. The optical fiber coupler comprises: a rare earth-doped fiber as an optical amplifying element; a quasi rare earth-doped fiber for entrance of input signal light; a fused-stretch fiber portion as a multiplexing element which connects a part of the rare earth-doped fiber and a parts the quasi rare earth-doped fiber, wherein the fused-stretch fiber portion formed by stretched a fused mixture of parts of the rare earth-doped fiber and the quasi rare earth-doped fiber; and a single mode fiber which is jointed at a fused joint portion to another shortened rare earth-doped fiber connected to the fused-stretch fiber portion on a side connected by the quasi rare earth-doped fiber. The quasi rare earth-doped fiber has substantially equal propagation constant to the rare earth-doped fiber without substantially containing rare earth elements. The optical fiber coupler is fabricated by the steps of jointing a single mode fiber with a rare earth-doped fiber by fusing abutted end faces of both fibers to form a combined fiber; and fusing parallel contact parts of a quasi rare earth-doped fiber and of the rare earth-doped fiber of the combined fiber and then elongating the fused parts in a desired diameter to form a fused-stretch fiber portion.

    摘要: It is intended to provide a carbonated beverage excelling in function as thirst-quenching beverage and taste through strengthening or sustaining of carbonated feel peculiar to carbonated beverage (brisk intense stimulation and sensation at pass through the throat, brought about by carbon dioxide gas, and sensation of coolness (refreshing sensation) produced by a combination of carbon dioxide gas and flavor) which after opening, rapidly drops depending upon a combination of employed raw materials, such as fruit juice, sweetener, color additives and flavoring, and upon evaporation of carbon dioxide gas. The drop of carbonated feel brought about depending upon a combination of raw materials, such as fruit juice and sweetener, can be relieved by adding to a carbonated beverage an additive for carbonated beverage comprising spilanthol or a spilanthol-containing plant extract or plant essential oil as an active ingredient. Further, the addition would help inhibit drop of carbonated feel brought about depending upon evaporation of carbon dioxide gas after opening and would help retain the taste and function as function as thirst-quenching beverage inherently to be had by carbonated beverage even after opening.
