摘要： An optical fiber device converts an input optical pulse having a predetermined center wavelength into an optical pulse having a wavelength bandwidth broader than that of the input optical pulse. The optical fiber device includes a plurality of optical fibers connected in a cascaded manner each having negative wavelength dispersion at the center wavelength. The optical fibers have different relative refractive index differences between a core region and a cladding region from each other. The optical fibers are connected such that wavelength dispersions of adjacent optical fibers at the center wavelength are different from each other.

摘要： When grooves 44, 45A and 45B of an armature 42 and a rotor 43 are formed by laser beam machining, a metal oxide layer 100 is formed on wall surfaces defining the grooves 44, 45A and 45B. The metal oxide layer 100 is brought into sliding contact with a first contact surface A1 to a fourth contact surface A4 in a process in which an electromagnetic clutch is used, so that a part of the metal oxide layer 100 is ground and peeled off, whereby particles made of a metal oxide are produced. The particles enter the contact surface between the armature 42 and the rotor 43, which increases the frictional force therebetween to thereby prevent slippage. As a result, the torque transmission capability of the electromagnetic clutch M is enhanced, and the increase in the torque of a scroll compressor is achieved.
