    Abstract: The invention provides a light-emitting device, where the active region thereof may be escaped from being damaged by the plasma process. The device is first formed with a semiconductor layer on the semiconductor substrate, next provided with an etching mask. Using the mask, the semiconductor layer on the substrate is dry-etched to form a periodic structure with grooves and mesas. The active regions are buried within the grooves by the OMVPE method.

    Abstract: As a composite laser rod capable of satisfying the positional stability and output stability of a laser beam, a laser rod in which a laser active element is doped is intimately inserted into a hollow portion of a non-doped ceramic pipe that has a crystal structure the same as the laser rod followed by baking so as to remove a gap and strain at an interface between the laser rod and the ceramic pipe after the baking further followed by polishing a surface of the ceramic pipe to form a ceramic skin layer, and thereby a composite laser rod is formed. In the composite laser rod, an influence due to fluctuation in the cooling capacity of cooling water or a heat sink is averaged by a non-doped skin layer, temperature fluctuation of the laser rod is suppressed, and an influence of vibration from the cooling water or a cooling fan can be suppressed. When the refractive index of the laser rod is made higher than that of the ceramic pipe, a high efficiency oscillation can be realized, and furthermore when the thermal conductivity of the ceramic pipe is made higher than that of the laser rod, the thermal lens effect can be alleviated.

    Abstract: Prefilled syringe for injection of two liquids includes a syringe body with an injection port at a closed end thereof, first and second gaskets fluid-tightly fitted into the syringe body to separate two medical solutions filled therein, and a closing member for closing the injection port. The syringe body is provided with bypassing grooves extending in the longitudinal direction of the syringe from a position adjacent to the closed end thereof. Liquid communication means is provided between the closed end and the first gasket. By pushing a plunger, the first and second gaskets are forced to move forward so that two medical solutions are injected one after another.
