    摘要: An ophthalmologic alignment device for aligning a measuring system at a predetermined position for an eye to be examined. The user moves the measuring system with a joystick for aligning purposes while observing a frontal eye image with an observation unit. A second moving unit further moves the measuring system moved by the user. An index projection/detection system projects an index onto the eye and detects the reflected index. The controller causes drivers to drive the second moving unit on the basis of the result of the detection of the index projection/detection system. A mode switch switches the movement of the measuring system from a mode in which the observation unit is moved by the first moving unit to a mode in which the observation unit is moved by the second moving unit, whereby the alignment of the eye and the measuring system is achieved easily and with high accuracy, irrespective of the degree of the user's skillfulness in handling the alignment device.

    摘要: A wavelength-tunable semiconductor laser which comprises a semiconductor substrate having first and second major surfaces, a distribution-feedback resonator having an active layer and a cladding layer, formed on the first major surface of the substrate and shaped like a stripe, and a first section and a second section aligned along the length of the resonator, and electrodes formed on the first and second sections of the resonator, respectively, for controlling current densities in the first and second section independently. The laser is characterized in that temperature changes more in the first section than in the second section, due to changes in densities of currents injected into the first and second sections.

    摘要: A self-dispersing graft-copolymer capable of self-dispersion in a high-electrical insulating carrier liquid to form grains therein. The graft-copolymer is combined with a pigment or dye to provide a self-dispersing solid colorant, which is suitable as a toner or toner supply for a liquid developing agent for electrostatic photography. The colorant is also applicable to a printing ink, an ink for an ink-jet system or a coating paint composition. The colorant well self-disperses in a carrier liquid to form well dispersed grains therein without the necessity of mechanical dispersing means.
