    摘要: A semiconductor laser device having an active layer sandwiched by semiconductor layers having larger energy band gaps than that of the active layer, includes a semiconductor absorption layer having an energy band gap no larger than that of the active layer and having a thickness periodically changing in the cavity length direction of the resonator, close to the active layer so that light which is generated at the active layer reaches the absorption layer, and a semiconductor refractive index matching layer, having a larger energy band gap than that of the active layer and a higher refractive index than those of the semiconductor layers sandwiching the active layer, to make the equivalent refractive indices in layer thickness direction substantially equal along the resonator direction.

    摘要: A distributed feedback semiconductor laser which achieves a phase shift for stabilizing the longitudinal mode without a substantial increase in reactive current and without introducing dimensional discontinuities in the laser stripe. The active layer of the laser is configured as a multi-quantum well and impurities are selectively diffused into the multi-quantum well to disorder a selected portion of the active layer. The disordered portion has an optical propagation constant which is different than that of the remaining stripe, and the difference in propagation constant coordinated with the length of the phase adjustment section produces a phase shift adequate to stabilize the laser longitudinal mode.

    摘要: A cleaning implement includes a cleaning head having on a bottom a cleaning operation surface, a holding portion arranged on the side opposite the cleaning head, a pipe for coupling the cleaning head and the holding portion, and a valve opening and closing device provided to the pipe so as to be able to hold a first container for receiving a first fluid or a second container for receiving a second fluid. The holding portion includes a lever coupled to the valve opening and closing device so as to open and close a first valve of the first container or a second valve of the second container. A spout of a second ejection nozzle for ejecting the second fluid containing an allergen inactivator is located, for example, at a height of about 30 cm or more from the floor.

    摘要: Disclosed is a cleaning device with a squirter for squirting liquid forward of a cleaning head. The cleaning head has a nozzle head whose squirt surface is curved. In the nozzle head, squirt directions of nozzles, which are arranged to fan out at a squirt angle, are substantially perpendicular to tangents to the squirt surface. Therefore, liquid squirted from the nozzles tends to fly straight along the squirt directions without being drawn to the squirt surface.
