Title: Semiconductor laser
Inventor: YOSHIKAWA AKIO
IPC: H01S5/00
Filed: 1986-02-24
Abstract: PURPOSE:To oscillate a semiconductor laser in a basic lateral mode with low threshold current value by reducing the forbidden band width of a layer which exhibits a conductivity type opposit to that of a clad layer smaller than other layer in a multilayer current blocking layer to prevent an internal stripe structure from invalidating. CONSTITUTION:A a P-type GaAS buffer layer 21, a P-type AlxGa1-xAs clad layer 22, an AlyGa1-yAs active layer 23, and an N-type AlzGa1-zAs clad layer 24 are continuously grown on a P-type GaAs substrate 20, and a current blocking layer 25 in which a P-type GaAs layer and an AlGaAs barrier layer are alternately laminated is formed on the layer 24. The layer 25 is etched in a stripe-shaped window, and partly etched in a depthwise direction until the surface of the layer 24 is exposed. A clad layer 26 and a contact layer 27 are grown thereon. In this case, the forbidden band width of the layer which exhibits a conductivity type opposite to that of the layer 24 is reduced than the other layer in the layer 25. As a result, the barrier layer in the layer 25 effectively shorten the diffusing length of minority carrier.

Inventor: ISHIKI SHIGERU
IPC: A01N59/20
Filed: 1997-02-25
Abstract: PROBLEM TO BE SOLVED: To reduce production cost by reducing amount of use of an antibacterial agent and further to improve productivity. SOLUTION: A glaze composition having transparency is compounded with an inorganic antibacterial agent so that added amount of the antibacterial agent is 0.2 to 10wt.%, preferably 1 to 5wt.% of the glaze composition to form an antibacterial glaze composition. In a pottery 1 on which an usual color glaze are glazed, a transparent glaze 3 of the antibacterial glaze composition is glazed on the usual color glaze 2 before baking and then both the color glaze 2 and the transparent glaze 3 are baked. Thus, color of the usual color glaze 2 is displayed on the surface and an antibacterial property can be also imparted by thinly glazing the transparent glaze 3 having the antibacterial property on the usual color glaze 2. Since amount of use of the antibacterial agent in reduced by reducing amount of use of the glaze having the antibacterial property, production cost can be reduced.  Further, since pottery dealing with several kinds of colors can be attained by preparing only one kind of the transparent glaze having the antibacterial property, productivity can be improved.
