Filed: 1986-03-04
Abstract: PURPOSE:To remarkably increase the light absorbing performance of a quartz group optical fiber as compared to other wavelength areas by doping a rare earth element on a core or the peripheral edge part of the core. CONSTITUTION:A rare earth element is doped on the core or the peripheral edge part of the core and a clad 1 having a refractive index smaller than that of the core is applied to the periphery of the core.

Filed: 1999-02-24
Abstract: PROBLEM TO BE SOLVED: To provide an electrode to be fitted to an organism, having strong holding force of an electrode piece at the time of measurement and allowing the electrode piece to be easily fitted or removed. SOLUTION: The slope 80 of a moving plate 78 fixed to a slider 36 is formed so that the distance to a fixed plate 68 in the direction perpendicular to the moving direction of the slider 36 becomes shorter as the slider 36 is moved by a spiral spring 76, and the distance between the fixed plate 68 and the moving plate 78 is increased when the slider 36 is moved against the force of the spiral spring 76. When the projection 54 of an electrode piece and the fixed plate 68 are coupled and the force pushing the lug 38 of the slider 36 is released in this state, the moving plate 78 is moved by the force of the spiral spring 76, and the projection 54 of the electrode piece located between the fixed plate 68 and the moving plate 78 is pinched by the fixed plate 68 and the moving plate 78.  The electrode piece fixed to a lower clip main body 22 is pinched by the force larger than the force of the spiral spring 76 by the principle of a slope, thus the electrode piece is reliably fixed to the lower clip main body 22 at the time of measurement.
