摘要： An optical fiber probe which has a minute opening on the top of a sharpened tip is allowed to get close to a sample, and the probe is moved by a piezo actuator along x- and y-axis directions so that a minute spot beam emanating from the minute opening can scan over the sample. For circular polarization modulation to be incorporated in the process, a beam, before it is incident on the optical fiber probe, is given an optical delay changing at a frequency of p (Hz) by means of a piezo-optical modulator. A minute spot beam emanating from the minute opening passes through the sample to be received after the passage through an analyzer by a light receiving element. The output from the light receiving element is fed to a lock-in amplifier, p- and 2p-components are separated through lock-in rectification, and they are rendered images by a controller.

摘要： In a toothed sintered pulley comprising a rim having a large number of teeth on its outer peripheral surface and lightening grooves at those portions of its inner peripheral surface which correspond to the individual teeth, a boss located radially inside of the rim, and a connection which connects the inner peripheral surface of the rim with an outer peripheral surface of the boss, the porosity of the rim is set larger than that of the boss. In addition, the connection is connected to axially intermediate portions of the inner peripheral surface of the rim, and lands are provided in a one-side half of the rim projecting from this connection in one of axial directions, so that each land is located between the two adjacent lightening grooves, with the radial thickness of the land being gradually increased from an outer end face of the one-side half toward the connection. This makes it possible to provide a toothed sintered pulley which is lightweight; in which any backlash noise due to meshing of the rim with a belt can be reduced, and the strength of the boss cannot be injured, and in which the rigidity of the one-side half in the rim is improved while suppressing the increase in weight thereof to the utmost.
