摘要： A feeding device that feeds a rolled paper to a printing apparatus is provided with a feeding mechanism, a tension measuring mechanism, and an outlet side guide roller. The feeding mechanism feeds a predetermined amount of the rolled paper in a forward direction so that slack is provided downstream of the outlet side guide roller. Thereafter, positioning is executed while recovering the rolled paper by feeding it in the opposite direction. The feeding mechanism further includes an inlet feeding mechanism and an outlet feeding mechanism. The inlet feeding mechanism performs a backward feeding of a small amount of the rolled paper, and the outlet feeding mechanism performs a forward feeding of a small amount of the rolled paper, in order to increase tension by pulling the rolled paper from both sides. With the feeding mechanism stopped, the tension measuring mechanism measures the tension, and repeats the process for increasing tension until it is not less than a predetermined value. This permits adequate adjustment of the initial state of a long recording medium when loading it, and prevents the recording medium from being consumed in vain due to a preliminary feeding and breakage.

摘要： A fault searching system searches for a fault in an optical line connected with an optical fiber carrying out data transmission between a transmission apparatus and a user optical terminal. A connecting unit detaches a terminal portion of the optical line at the user optical terminal, and connects an OTDR to the terminal portion of the optical line. At least one of a test light with a wavelength different from a wavelength of light used for data transmission in the optical line, and a test light whose peak level is less than or equal to a predetermined level, is caused to be incident upon the terminal portion of the optical line. A searching unit searches for a fault in the optical line from the user optical terminal side by detecting backward scattering light or return light from the optical line produced by the test light caused by the OTDR.

摘要： An imaging optics capable of compensating for chromatic aberration is provided with a light shielding means in a surface peripheral area of a certain lens element in a lens system so as to block a light flux of a specified wavelength range, thereby eliminating chromatic aberration in halo of the light flux of the specified wavelength range when it passes the periphery of the lens system. Thus, the invention provides the imaging optics that, without an increase in the number of pieces of lens elements and without a use of an expensive specified low-dispersion glass material, in contrast with the prior art imaging optics of the same optical performances, well compensates for chromatic aberration, especially, in halo.

摘要： An optical communication equipment comprises shared optical sources 88a–88d to be shared by communication nodes 100a–100d, the wavelengths of optical signals 76a–76d are converted into desired wavelengths λa–λd according to the addressed information of the corresponding optical label signals 77a–77d by using the shared optical sources 88a–88d, and routed to the addressed communication nodes without being converted into electrical signals by using the wavelength routing function of the cyclic-wavelength arrayed-waveguide grating (AWG) 120. The load of each communication node can be reduced by incorporating the multi-wavelength optical sources, which can be shared among individual communication nodes, into the router 80. Further, each communication node is provided with an optical gate or the like for returning the optical signal to the communication node from which the optical signal has been transmitted through the router 80 in order to adjust the transmission time lag between the optical signal and the corresponding optical label signal by the controllers 110a–110d.

摘要： A printed image without rosette moire can be produced by adjusting positional relations among halftone images. Halftone dots (M.sub.1, C.sub.1) of magenta and cyan printers are placed at a reference position (P.sub.1). A halftone dot (K.sub.1) of black printer is placed at a position (PK.sub.1) which is half a screen pitch (d.sub.1) distant from the reference position (P.sub.1) in one of a first direction representing the screen angle (45.degree.) of the halftone image for the black printer and a second direction inclined at 90.degree. away from said first direction. Screen angles of respective halftone images are set so that each of differences between screen angle (15.degree., 45.degree.) of the cyan and black printers and between screen angles (75.degree., 45.degree.) of the magenta and black printers is about 30.degree..
