Abstract: The present invention relates to an anchor bolt and more specifically pertains to a post-installed anchor that is securely anchored to, for example, an existing concrete floor. The post-installed anchor has a sleeve fit on a bolt body and a fixation member arranged on an edge of the bolt body and screwed to a threaded end of the bolt body. The fixation member has an internal threaded end and an expansion end. The expansion end is divided into four expansion pieces by slits. The expansion pieces are arranged to face a head of the bolt body and are slightly widened toward the head of the bolt body. One end of the sleeve forms a tapered face. After insertion of the post-installed anchor into a pilot hole (installation hole) bored in the concrete floor, as the bolt body rotates, the fixation member screwed to the bolt body moves toward the sleeve. This movement causes the expansion end of the fixation member to ride on the tapered face of the sleeve and to be pressed open and extended outward. The expansion pieces of the expansion end are then buckled and bite into an inner circumferential face of the installation hole, so that the post-installed anchor is securely fixed to the installation hole.

Abstract: In a coherent optical receiver, a light intensity value of signal light providing an optimum reception state is determined when ideal signal light free from waveform distortion is used as the signal light in a state where local-oscillator light is turned on. A first amplitude value of an analog electrical signal corresponding to the signal light is stored in a storage section, wherein the first amplitude value is obtained at a time when the ideal signal light of the light intensity value determined is used as the signal light in a state where the local-oscillator light is turned off. Light intensity of the signal light is determined so as to make a second amplitude value equal to the first amplitude value, wherein the second amplitude value is an amplitude value of the analog electrical signal which is obtained at a time when actual signal light is used as the signal light in a state where the local-oscillator light is turned off.

Abstract: A dispersion compensation apparatus capable of compensating for dispersion while the state of polarization is maintained overall all channels between the input and output ends. Input signal light in alignment with the transmission polarization axis of a polarization beam splitter passes through the multiplexer and a wavelength dispersion-compensating device and is reflected by a Faraday rotator mirror so as to pass through the wavelength dispersion-compensating device again. Owing to the action of the Faraday rotator mirror, the signal light that returns to the wavelength dispersion-compensating device has a polarization that is orthogonal to the polarization that prevailed when the signal light first passed through the device. Thus the polarization beam splitter now operates in the reflective polarization mode with respect to the returning signal light. As a result, 100% of the signal light is output to a Polarization-maintaining optical fiber. Moreover, the polarization is fixed linear polarization.
