摘要： PROBLEM TO BE SOLVED: To provide an internal pressure regulator for an endoscope which prevents infiltration of moisture into the endoscope by a porous member which is disposed in a valve opening adapter, has no water permeability but has air permeability, permits rapid passage of air of an amount sufficient for restoring the pressure in the endoscope and assures water-tightness. SOLUTION: The valve opening adapter 30 is formed of a check valve junction 30A attached and detached to and from a check valve 10, a water-tight vent portion 30B arranged with a porous member 40 and a pliable vent pipe 31 communicating the check valve junction 30A and the water-tight vent portion 30B. The porous member 40 is formed to a flat circular sheet form, is held between a pair of net-like retaining members 39 and is arranged at the water- tight vent portion 30B.

摘要： PROBLEM TO BE SOLVED: To provide a method by which a flexible tube for endoscope for which brazing and soldering can be used at the time of fixing a spiral tube to a braided body even when heat treatment is performed on the jacket of the tube and in which the spiral tube and braided body are coupled with the jacket with strong coupling forces (adhesion) can be manufactured. SOLUTION: This method includes a step of manufacturing a tube member 3 by putting the jacket 5 on a netted pipe 4 so as to cover at least part of the tube 4, a step of passing a core material 82 through the spiral tube 6 having an outside diameter D larger than the inside diameter (d) of the tube member 3 in a natural state and temporarily fixing the core material 82 by reducing the diameter of the tube 6 so that the reduced outside diameter D' of the tube 6 may become D'

摘要： PROBLEM TO BE SOLVED: To highlight always uniformly without unevenness an object field, even if the positional relation between the incident light end and the light source lamp is caused to make a dislocation, by making random the optical fiber alignment at the incident light end so that a multiple number of optical fibers at the injection end is entangled as a whole. SOLUTION: At the light emitting ends 11 provided by dividing a light guide fiber bundle 10 into two parts and at the incident light end 12 made together the optical fibers into one bundle, the optical fibers are bundled as they are passing through the mouth metals 13, 14. These two light emitting ends 11 of the light guide fiber bundle are made to an almost same form. At a side of the incident light end 12, the light guide fiber bundles divided into two bundles at a side of the light emitting ends 11 are aligned randomly so that they are near-uniformly entangled as a whole. This allows the light to be emitted out through these two light emitting ends with a same brightness and a same scope, even if the light were entered at any state into the light guide fiber bundles through the incident light end.
