    摘要： In a sealing device (1) , in which a main seal lip (6) used for a shock absorber is formed in a one-stage seal lip structure, for the purpose to improve friction characteristics while securing sealing performance, a roughened portion (63) to which satin finishing is applied to form projections and recessions on the surface thereof is formed on the sliding surface (61) of the main seal lip (6) slidably moving on a contacting member at a position apart a specified distance from a lip edge (62). An area between the lip edge (62) and the portion where the roughened portion (63) is formed is a plane portion (64) to which the satin finishing for forming irregularities is not applied. In place of the satin finishing, a plurality of axially extending projections (65), concave threads (67), or lattice-shaped projections (68) may be formed on the roughened portion.

    摘要： In conventional optical isolators, an optical signal is dispersed by polarization or the characteristics are varied by heat generation in a garnet crystal. According to the invention, the crystal optical axis (3c) of rutile crystal (3) is oriented so that the separation directions of the ordinary ray (O) and the extraordinary ray (E) are perpendicular to the plane including the optical axes of optical fibers (10, 11). Furthermore, the focusing central optical axis (6c) of a focusing rod lens (6) is arranged parallel with optical axes of the optical fibers (10, 11) and at a substantially equal distance from the four rays, i.e. the ordinary ray (O) and the extraordinary ray (E) propagating along the optical axis of the optical fiber (10) and the ordinary ray (O) and the extraordinary ray (E) propagating along the optical axis of the optical fiber (11). An air gap (7) of about 200 [μm] is provided, as a heat insulating means, between the focusing rod lens (6) and a magnetized garnet crystal (8).

    摘要： A toner density on a toner image carrier means such as an intermediate transfer belt is accurately measured, even if a durability of the toner image carrier means is changed. It is assumed that output dark voltages from said first and second photo-detector means are P0 and S0, respectively; back-ground voltages from said first and second photo-detector means are Pg and Sg, respectively, when any toner is not attached on said toner image carrier means; measured voltages from said first and second photo-detector means are P and S, respectively, when said toner image was formed on said toner image carrier means. Then, a coverage rate CR and a durability X are calculated by the following formulae. CR=1−((P−P0)−(S−S0))/((Pg−P0)−(Sg−S0)), X=A×(1−(Sg−S0)/((Pg−P0)). Further, the toner density is obtained on the basis of the corrected CR by using durability X as a parameter.
