    摘要: A GaAs based semiconductor laser has a combination of cladding layers including a ridge structure part, and a remaining part which overlays the active layers of the laser, and an etch stop layer sandwiched between the ridge structure part and the remaining part. The remaining part preferably overlies the entire surface of laser active layers and has a thickness “D” which satisfies 1.1×W>D≧0.5×W wherein W is the width of a spot size having a strength of {fraction (1/e2)} as measured at the laser front facet in a direction perpendicular to the active layers, wherein “e” is the base of the natural logarithm. The semiconductor laser solves the kink phenomenon to obtain an excellent linear relationship between the optical output power and the injected current.

    摘要: The semiconductor laser element comprises, from bottom to top, the p-AlxGa1-xAs upper clad layer, p-AlyGa1-yAs resistance control layer, and p-GaAs cap layer (where x>y>0.2). A portion of only the resistance control layer and cap layer is selectively etched. The etchant used for this etching is a mixture of organic acid and hydrogen peroxide based mixture, has such a composition such that the ratio of dissolution rate of the upper clad layer to the cap layer is between 10 and 20, and pH is between 7.4 and 7.6.

    摘要: A snow vehicle of the saddle-riding type utilizes essentially the same upper structure as a motorcycle but mounts a ski on the front fork for steering and an engine-driven endless belt track assembly for powering the device. The endless belt track assembly is arranged for mounting on a rear arm structure in order to maintain surface contact between the endless belt and the snow and thereby improve the operating efficiency of the vehicle. The arm may be pivotally mounted or integral with a rear fork pivotally mounted to the vehicle. An improved endless belt construction is described in which the belt is strengthened by core members and the driving cogs of particular configuration and disposed at prescribed locations with respect to the propelling lugs in order to maintain surface contact between the belt edge and the snow surface during cornering. Also disclosed are various forms of cover structures for the track assembly that prevent the scattering of snow from the belt onto the rider or vehicle parts. Grab rails attached to the rear swing arm elements facilitate manipulation of the vehicle in confined spaces. A stopper belt adjustment is also shown mounted to a rear fork with the stopper belt extruding to an articulated rear swing arm structure. The adjustment accommodates for adjustments to the drive chain for tensioning.
