Abstract: A semiconductor lamination portion (6) is formed by laminating nitride semiconductor layers including an n-type layer (3) and a p-type layer (5) on one side of a substrate (1) so as to form a light emitting layer, and a light transmitting conductive layer (7) is provided at a surface side of the semiconductor lamination portion. A concave-convex pattern, i.e., concaves (7a), is provided on a surface of the light transmitting conductive layer. A p-side electrode (8) is provided on the light transmitting conductive layer, and an n-side electrode (9) is electrically connected to the n-type layer exposed by etching a part of the semiconductor lamination portion.

Abstract: There is provided an apparatus for measuring a position of a linear type valve which is open/shut by operation of a hydraulic cylinder. More particularly, the apparatus more accurately measures a valve position by outputting a rotation angle of a rotation sleeve which rotates by being operatively connected to a hydraulic cylinder which moves linearly, and by calculating a vertical movement distance of a valve gate which changes in proportion to the rotation angle. Further, since the structure of the apparatus is very simple, the cost of production is significantly reduced. In addition, for use, the apparatus is installed on the hydraulic cylinder by a simple method.
