    摘要: In a diffractive element, its grating pattern is so configured that a diffraction angle of a diffracted light beam of a light source that is subject to the first-order diffraction in a diffraction area is matched with an angle of a light beam passing through the diffractive area emitted from a light source and a light source position is matched with a light originating point of the light source that emits a light beam to be transmitted, and the center of light intensity distribution is matched with that of the light source passing through the diffractive element by inclining an optical axis of the light source. A position of the diffractive element is adjusted based on an electric current value generated when a reflected return path light beam of the light source is diffracted by the diffractive element and enters the light source.

    摘要: In a semiconductor laser device, a semiconductor laser chip is placed on a stem so that an end surface of the semiconductor laser chip, on which the main radiation side light emission point is located, protrudes from an edge of a header portion of the stem or from an edge of a header portion of a sub-mount provided on the stem so as to conceal no light emission points of the semiconductor. A conductive die bonding paste is used for the die bonding of the semiconductor laser chip. A chamfered portion or a rounded corner portion is formed at the edge of the header portion of the stem or the edge of the header portion of the sub-mount provided on the stem. Also, an optical pickup is constructed of at least the semiconductor laser device, a diffraction grating, a photodetector, a condenser lens and an object lens.

    摘要: A cap member capable of alleviating degradation of reliability and improving fabrication yields is provided. The cap member has a cylindrical side wall portion, a top face portion closing one end of the side wall portion and having a light exit hole formed therein to allow extraction of laser light from a semiconductor laser chip; a light transmission window fitted to the top face portion to stop the light exit hole, and a flange portion arranged at the other end of the side wall portion and welded on the upper face of a stem on which the semiconductor laser chip is mounted. A groove portion is formed in an inner surface of the top face portion, and this groove portion makes part of the top face portion in a predetermined region less thick than the other part thereof.

    摘要: A continuously operative printing machine and a method of operating the same are disclosed. The printing machine has a plurality of switchable printing units to be used selectively by switching. For continuous printing the printing units are switched alternately by coupling and decoupling first coupling/decoupling means while a continuous printing web is held running. Plate change of stationary printing units is done with independent drive means to be ready for the next printing. Then the stationary printing units are restored to the printing state through synchronous control by rotational control means. Thus plate change printing or the like can be carried out continuously without stopping the printing machine. In addition, high quality printing can be obtained efficiently. Further, it is possible to obtain double side printing.
