摘要： A semiconductor device of the invention is formed so that n-type InP current blocking layers enter the inside of p-type InP cladding layers, i.e., the n-type current blocking layers ride over the upper part of the p-type InP cladding layers, so that a distance between the n-type InP current block layers composing a current blocking region is narrower than a width of the p-type cladding layers contacting with the n-type InP current blocking layers. Thereby, the semiconductor device whose leak current in the current blocking region may be reduced which permits high-output and high-temperature operations may be readily fabricated.

摘要： [Problems]To provide a lost-wax cast impeller for a supercharger having no parting line corresponding part on a hub surface and a blade surface in each space demarcated by pairs of long blades adjacent to each other and having excellent aerodynamic performance. [Means for Solving Problems]This method of manufacturing the impeller comprises a step for forming a lost form pattern formed in the substantially same shape as the impeller for the supercharger, a step for forming a mold by eliminating and removing the lost form pattern after the lost form pattern is coated with a refractory, and a step for pouring a molten metal in the mold for casting. In the step for molding the lost form pattern, a lost material is injection-molded in a space demarcated by radially arranging, toward a center shaft, a plurality of slide molds having short blade-shaped bottomed groove parts and space shapes between the pairs of long blades adjacent to each other, and the slide molds are released by moving in the radial direction of the center shaft while rotating. Thus, the parting line corresponding part is not present on any of the hub surface and the blade surface in the spaces demarcated by the pairs of long blades adjacent to each other.
