摘要： An input monitoring unit monitors full input light and outputs an input monitor signal. An output monitoring unit monitors full output light and outputs an output monitor signal. An ASE compensating circuit compensates for an ASE component contained in the output monitor signal. A gain-variation-level compensating circuit calculates a target average setup gain that is determined based on a signal intensity of the input monitor signal. A constant gain control circuit performs a gain control based on an output signal from the ASE compensating circuit and the target average setup gain.

摘要： In an electromagnetic clutch, a rotor, an armature and a stator housing including an electromagnetic coil are assembled to a center hub through a bearing member. Therefore, by assembling the center hub to an engine crank shaft, an assembling operation of the electromagnetic clutch to a vehicle is finished. In addition, a stator plate fixed to the stator housing is fixed to an engine through a bushing made of an elastic material. Therefore, a vibration displacement of the stator housing relative to the rotor, generated due to vibration of the engine, can be absorbed.

摘要： An overhang type electromagnetic clutch used for selectively connecting the rotation of an internal combustion engine to a compressor for an air conditioning system for an automobile. The clutch is provided with a rotor having a sliding surface axially spaced from an outer end of a pulley arranged around the rotor. A bit, which initially is in contact with the sliding surface at a location spaced from the axis of the rotation of the rotor, is radially moved while the rotor is rotated, so that radially spaced apart tool marks eccentric to the axis of the rotation of rotor and having a gradually increased radius are formed on the entire region of the sliding surface. An increased engagement of the sliding surface with an armature is obtained due to the provision of engagements in the circumferential direction. A bit, which initially is in contact with the sliding surface at a location corresponding to the axis of the rotation of the rotor may be first moved radially outward while the rotor is rotated, so that radially spaced apart first tool marks concentric to the axis of the rotation of rotor and having a gradually increased radius are formed on the entire region of the sliding surface. The bit is then moved radially inward so that radially spaced apart second tool marks concentric to the axis of the rotation of rotor and having a gradually decreased radius are formed on the entire region of the sliding surface. As a result, the first and second tool mark cross and provide an engagement in the circumferential direction.

摘要： There are disclosed herein a method and an apparatus for manufacturing tubes or tubular bodies by means of hydrostatic extrusion, which tubes or tubular bodies have axially running holes therethrough having cross-sections of irregular shapes. The method and apparatus utilize a mandrel of novel construction which comprises a conical tip portion having a smooth peripheral surface, a cut or grooved intermediate portion with a sloped groove starting at a peripheral edge and a body portion formed with a flange and adapted to move longitudinally of a pressure chamber, as necessary. The conical tip portion is specifically intended to seal against the conical end of a metallic billet. Unless there is such a provision, there would be leakage of a fluid through the grooved portion because of direct contact of the grooved edge with the inner end surface of the billet. Thus, this method and the apparatus for performing the method enables one-step extrusion of tubes or tubular bodies having inner fins or inner walls having irregularly shaped cross-sections, with the accompanying advantages of providing complete sealing among the die, the billet and the mandrel, particularly in the initial stage of the extrusion.

摘要： Provided is a point-to-multipoint optical communication system capable of extending a transmission distance between a subscriber apparatus and a station apparatus without changing wavelengths of an upstream optical signal and a downstream optical signal, which are used in both of the apparatuses. The point-to-multipoint optical communication system includes, as a basic configuration thereof, an optical network for connecting one station apparatus (1) to a plurality of (n) subscriber apparatuses (4). Among m basic configurations, one station-side wavelength multiplexer/demultiplexer (22), one optical fiber transmission line (30), and one subscriber-side wavelength multiplexer/demultiplexer (12) are shared. The point-to-multipoint optical communication system further includes a station-side repeating unit (20) and a subscriber-side repeating unit (10) each including the one wavelength multiplexer/demultiplexer (22 or 12) and m wavelength converters (21 or 11). An optical signal having a conventionally-used wavelength is used between the station apparatus (1) and the station-side repeating unit (20) and between the subscriber apparatus (4) and the subscriber-side repeating unit (10), and an extensible optical signal, on which wavelength division multiplexing has been performed, is used between the wavelength multiplexers/demultiplexers (12 and 22) via the optical fiber transmission line (30).
