摘要： A high-power acceptable optical fiber comprises a core and cladding provided on the outer peripheral surface of the core. The dopant concentrations in the core and cladding each change in the axial direction of the optical fiber. The core has a same relative refractive index profile in any cross section thereof taken in a direction perpendicular to the axial direction thereof. The relative refractive index profile is normalized by a maximum refractive index of the core.

摘要： A single-polarization optical fiber comprising a core, an inner cladding surrounding the core, an outer cladding surrounding the inner cladding and at least one pair of stress-applying portions each of which are partially extended into both the inner and outer claddings and which are symmetrical about the axis of the core and having thermal expansion coefficient higher than those of both the inner and outer claddings. When the refractive index of the stress-applying portions is lower than that of the core and higher than that of the inner cladding and further not higher than that of the outer cladding, one of orthogonally polarized mode is cutoff and only one polarized mode can propagate in the optical fiber.

摘要： A 1.5 .mu.m zero dispersion single mode optical fiber comprising a center core, a side core disposed on an outer side of the center core and having a refractive index lower than that of the center core, and a cladding portion disposed on an outer side of the side core. Each of the refractive indices of the center core and the side core has a step-like profile in the direction of the radius of the optical fiber. The bending loss is low. The mode field diameter can be increased without deteriorating the bending loss, and the splice loss can be reduced. The chromatic dispersion varies only to a small extent with respect to changes in the core diameter, so that the zero dispersion wavelength can be well controlled.

摘要： In order to heat and warm only the amount of water required in immediate future and to reduce a power consumption by avoiding warming of unnecessary water, a main body provided with a water storage container and a water heating container can be attached and detached and a water heating amount or a water warming amount to be heated at one time is reduced and divided, thus, power consumption during warming is reduced. Furthermore, since the water storage container is provided independently, water supply can be carried out conveniently regardless of the state of the water-heating container. Water supply to the water-heating container is carried out automatically using a water amount sensor, hence no operation by a user is required.
