Abstract
Abstract A connecting structure for an optical conductor tube having an optical conductor rod inserted in a pipe to connect it vertically and in cascade fashion with another optical conductor tube and also having an inserted optical conductor rod. A transparent spacer of a diameter approximately equal to that of the optical conductor rods is interposed between them and the circumferential portion of the spacer has arc-shaped notches at a plurality of locations thereon. The notches have a transparent support arm engaged therewith and are elongated toward the pipe. The support arm is fixed clippingly by the flange.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
101 words
(1) A connecting structure for an optical conductor tube, having an optical conductor rod inserted in a pipe, to connect it vertically and in cascade fashion with another optical conductor tube, also having an inserted optical conductor rod, is characterized in that a transparent spacer of a diameter approximately equal to that of said optical conductor rods is interposed between them and a circumferential portion of said spacer has arc-shaped notches at a plurality of locations thereon, said notches having a transparent support arm engaging therewith and being elongated toward said pipe, said support arm being fixed clippingly by said flange.
Claim 2
Dependent Claim
48 words
(2) A connecting structure for an optical conductor tube as defined in Claim 1, is characterized in that an edge surface of said optical conductor tube projects from that of said flange and said support arm is clippingly fixed to said flange by means of an elastic packing.
Claim 3
Dependent Claim
35 words
(3) A connecting structure for an optical conductor tube as defined in Claims 1 or 2, is characterized in that an optical paste or oil is interposed between said optical conductor rod and said spacer.
Claim 4
Dependent Claim
44 words
(4) A connecting structure for an optical conductor tube as defined in either one of Claims 1 through 3, is characterized in that said optical conductor tube and said support arm are engaged with each other by means of optical paste or optical oil.
Claim 5
Dependent Claim
41 words
(5) A connecting structure for an optical conductor tube as defined in either one of Claims 1 through 4, is characterized in that the front surface of said support arm's portion, protruding from said spacer, is used a.s a reflecting mirror.
Claim 6
Dependent Claim
111 words
(6) A connecting structure for an optical conductor tube, having an optical conductor rod inserted in a pipe, to connect it with another optical conductor tube, is characterized in that an optical jelly of a refractive index which is approximately equal to that of said optical conductor rod is placed in the space between the connecting surfaces of said optical conductor rods, and a spacer is interposed between said optical conductor rod and said pipe through the use of an optical jelly or adhesive having a refractive index smaller than that of said optical conductor rod, said pipe being connected through the means of a flange in conjunction with another flange.
Claim 7
Dependent Claim
27 words
(7) A connecting structure for an optical conductor tube as defined in Claim 6, is characterized in that said spacer has- holes for pouring in the adhesive.
Claim 8
Dependent Claim
42 words
(8) A connecting structure for an optical conductor tube as defined in Claims 6 or 7, is characterized in that said flange is connected with said pipe through means of a packing which is approximately equal to that of said optical jelly.
Claim 9
Dependent Claim
48 words
(9) A connecting structure for an optical conductor tube as defined in either one of Claims 6 through 8, is characterized in that said flange is fixed to said pipe by means of a screw and mounted thereon so as to move along the axis of said pipe.
Claim 10
Dependent Claim
38 words
(10) A connecting structure for an optical conductor tube as defined in either one of Claims 6 through 9, is characterized in that the outer circumferential surface of said flange is constructed in the form of a hexagon.
