    摘要: In the case of using a plurality of printing means, even if a feeding speed of each printing means of the plurality of printing means is varied, a print of superior quality is always provided. The electronic print-board apparatus comprises a printing device for supplying a paper sheet P by a feeding roller to a printing section that is formed by a printing head and a platen roller and a control system. The control system pauses or reduces a speed of the feeding roller according to detection of a leading end of the paper sheet P by a paper detecting sensor so that the paper sheet P reaches the printing section coincidentally when an optical reading device starts scanning an image on a surface of a screen as it is revolved.

    摘要: An impurity-doped double-heterostructure semiconductor laser adapted for single-longitudinal-mode operation is disclosed which includes a semiconductive substrate and a mesa of double-heterostructure formed over the substrate. The mesa comprises an active layer serving as a light-emitting layer, a waveguiding layer adjacent to the active layer and clad layers interposing the active layer and the waveguiding layer therebetween. A high-resistively layer is formed to bury the lateral surfaces of the mesa. The active layer contains impurities of a rare earth element with a previously selected concentration. The limited concentration of impurities is high enough to confine only light components falling within a specific range of wavelength, of all the light components produced in the active layer when the laser device is operative, within the active layer so as to provide single wavelength laser oscillation and low enough to inhibit the initiation of spontaneous emission of the rare earth element within the active layer. For example, the concentration may be set to 1.times.10.sup.18 cm.sup.-3 or below.
