In a floating unit, a floating mechanism is provided with: a rolling portion that includes a holding portion fixed to one of a first member and a second member, a sphere held by the holding portion so as to be rotatable in all directions; and an opposing portion that is fixed to the other one of the first member and the second member, and has an abutment surface that abuts against the sphere. The abutment surface includes an inclined surface that is formed, over the entire region of the abutment surface in a circumferential direction around a reference position, so as to come close to a side, in the vertical direction, on which the sphere is arranged, while extending outward in the horizontal direction from the reference position.

Floating unit

An optical transmission fiber having improved mechanical strength and suitable for use in optical communication comprising an optical fiber having formed thereover at least one layer of a composition mainly comprising a thermoplastic resin having a functional group, and a method for making the optical transmission fiber.

Optical transmission fiber

An optical transmission fiber which is formed by applying and baking a liquid resin composition or a solution or a dispersion prepared by dissolving or dispersing in a solvent a liquid or solid resin composition onto a glass fiber for optical transmission and, further, coating thereover by melt extrusion a thermoplastic resin composition.
