1. A beverage that comprises saccharides and which satisfies all of the following conditions (i) to (iii):
(i) the total weights of mono-, di- and trisaccharides contained in the beverage account for 75% or more of the total weight of all saccharides contained in the beverage;
(ii) the ratio of the total weight of the disaccharides to that of the trisaccharides is from 5:1 to 9:10; and
(iii) the osmotic pressure is from 30 to 130 mOsmKG.
2. The beverage according to claim 1, wherein the total content of all saccharides per 100 g of the beverage is from 0.5 to 10 g.
3. The beverage according to claim 1, wherein the total content of the trisaccharides per 100 g of the beverage is from 0.05 to 2.70 g.
4. The beverage according to claim 1, wherein the total weight of the monosaccharides accounts for 2.0 to 70% of the total weight of all saccharides.
5. A process for producing a beverage, which comprises the following steps (i) to (iii):
(i) adjusting the makeup of saccharides in the beverage such that the total weights of mono-, di- and trisaccharides contained in the beverage account for 75% or more of the total weight of all saccharides contained in the beverage;
(ii) adjusting the concentrations of the di- and trisaccharides in the beverage such that the ratio of the total weight of the disaccharides to that of the trisaccharides in the beverage is from 5:1 to 9:10; and
(iii) adjusting the osmotic pressure of the beverage to lie from 30 to 130 mOsmKG.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
What is claimed is:
1. In an endoscopic insertion instrument having a rigid tip end section with an observation window and an illumination window, an elongated flexible body, and an angle section connected between said rigid tip end section and said flexible body:
a joint construction for connecting said angle section to said flexible body of said endoscopic insertion instrument, comprising:
a couple of connecting rings opposingly provided at joining ends of said angle section and said flexible body for fitting engagement with each other, one on the outer side of the other one;
an aperture or a plural number of apertures provided in an outer one of said connecting rings to supply solder to overlapped joining surfaces of said connecting rings at the time of fixedly soldering said connecting rings to each other;
at least one operating wire threaded and extended through said angle section and said elongated flexible body of said insertion instrument via said connecting rings for flexibly bending said angle section;
a closed sheathing coil coextensively provided in said flexible body for encasing said operating wire and having a fore end portion thereof securely fixed to an inner one of said connecting rings; and
a fluid-tight shield portion formed on and around outer periphery of said closed sheathing coil over a predetermined range in axial length, including at least proximal end portions of said inner connecting ring, to prevent a flux from intruding into said closed sheathing coil at the time of soldering said connecting rings together.
2. A joint construction for an endoscopic insertion instrument as defined in claim 1, wherein said closed sheathing coil is fixed to said inner connecting ring through an anchor pipe in the shape of a stepped pipe having a small diameter portion on the front side of a large diameter portion adapted to anchor a fore end portion of said closed sheathing coil therein, said small diameter portion of said anchor pipe being stopped in one of said connecting rings and internally providing a wire passage for said operating wire which is led out of said closed sheathing coil.
3. A joint construction for an endoscopic insertion instrument as defined in claim 2, wherein said anchor pipe is fixedly stopped in said inner connecting ring by means of an anchor pin.
4. A joint construction for an endoscopic insertion instrument as defined in claim 1, wherein said inner connecting ring is a connecting ring on the side of said angle section of said insertion instrument.
5. A joint construction for an endoscopic insertion instrument as defined in claim 4, wherein said shield portion into a helical coil structure of said flexible body of said insertion instrument beyond said connecting ring on the side of said flexible body.
6. A joint construction for an endoscopic insertion instrument as defined in claim 1, wherein said shield portion is formed of a soft and resilient material.
7. A joint construction for an endoscopic insertion instrument as defined in claim 6, wherein said shield portion is formed by applying a resilient seal material on and around outer periphery of said closed sheathing coil.
8. A joint construction for an endoscopic insertion instrument as defined in claim 6, wherein said shield portion is formed by fitting a flexible tube on outer periphery of said closed sheathing coil.
