    摘要: There is provided a tool positioning device and a machining element whose structures are simple and which can reduce a running cost. In addition to a hole that engages with a shank of an end mill, a channel is provided so that it penetrates through the device such that one end thereof communicates with an upper face of the device and the other end communicates with a lower end of the device. In this case, it is more effective to provide a concave portion that is opened to the upper face and communicates with the hole. The same effect may be obtained by making a cylindrical hole for example instead of the channel.

    摘要: A semiconductor light emitting element comprising an n-type semiconductor substrate and a light emitting part comprising an n-type cladding layer composed of an InGaAlP compound semiconductor material, an active layer and a p-type cladding layer formed in that order from the substrate side by double heterojunction, wherein said semiconductor light emitting element satisfies at least one of the following conditions: A. the thickness of said active layer being greater than 0.75 .mu.m and not more than 1.5 .mu.m, and B. the thickness of said p-type cladding layer being 0.5 .mu.m-2.0 .mu.m. According to the light emitting element of the present invention, an overflow of electron into the p-type cladding layer can be suppressed by setting the thickness of the active layer and the p-type cladding layer to fall within the above-mentioned specific ranges, as a result of which the element shows luminous efficiency peaked within the specified range.
