摘要： A multi-core fiber for accommodating multiple single mode cores in one optical fiber is provided with multiple types of non-identical cores having different propagation constants. Each of the multiple types of non-identical cores includes a core part and a cladding part covering an outer periphery of the core part. The cladding part has a double cladding structure including a first cladding for surrounding an outer periphery of the core part and a second cladding on the outer side of the first cladding. In the multiple types of non-identical cores, an optical electromagnetic profile in the core part and the first cladding is confined within a range of the core part and the first cladding, restricting a leakage thereof to the second cladding, and the propagation constant of each non-identical core is made different using the refractive index of the first cladding as a parameter.

摘要： This invention provides an oil seal that can maintain an excellent friction reduction function over a long period of time, has excellent abrasion resistance, and further has excellent sealing properties. The oil seal comprises a seal lip (4) formed of a rubber-like elastic material comprising a lip edge part (9) and an air-side slope (8) and a sealing fluid-side slope (10) provided on both sides of the lip edge part (9). The air-side slope (8) has a coating film (14) on its surface. In the lip edge part (9) in its portion in contact with a shaft (13), a sealing fluid-side rubber part (2′) and an air-side coating film (14) are simultaneously brought into contact with the shaft (13). The coating film (14) is preferably formed of a coating agent comprising a fluororesin, a polyethylene resin, an isocyanate-modified polybutadiene resin, and a solvent.
