IPC: E02B7/02
Filed: 1982-09-27
Abstract: PURPOSE:To obtain a water reservoir dam for ground water at low cost by a method in which plural water-proof bags filled with water are settled in sea water to form a water reservoir dam in such a way as to harmonize both the pressures of the water as service water and the sea water with each other. CONSTITUTION:Plural large oblong cylindrical bags 2 impervious to water, the upper parts of which are attached with circular floating covers 3, are settled in the sea water. Water-inducing pipes 5 and water supply pipes 6 are attached to the covers 3 and fixed to the bags 2, and weights 4 are attached to the lower ends of the bags of the bags 2 to prevent the entanglement of the bags 2 vacated by pumping and floated. The bags 2 group is surrounded by a floating breakwater 1 and a flow preventive fence 8 for the bags 2 is provided to the lower part of the breakwater 1. Since no water pressure from the filled water and the sea water applies to the bags 2, much stronger bags 2 are not needed and the construction cost is reduced. Also, since no cold ground water srings out of the seabed, effects on fish and sea weed can be improved.

Title: Semiconductor laser and manufacture thereof
Inventor: MANNOU MASAYA
IPC: H01S5/00
Filed: 1989-06-30
Abstract: PURPOSE:To perform high output with a single transverse mode and stable operations for a long time by allowing a semiconductor laser to be equipped with a buried layer covering side faces of an active layer and a photoabsorption layer which absorbs light leaking out from the neighbourhood of both ends of the active layer in the semiconductor laser having double heterostructure which makes (AlxGa1-x) InP act as the active layer and furthermore, (AlyGa1-y) InP act as a clad layer on a GaAs substrate, thereby making the buried layer have a prescribed composition. CONSTITUTION:An n-type AlGaInP clad layer 2, a GaInP active layer 3, a p-type AlGaInP clad layer 4, and a p-type GaAs cap layer 5 are formed in order on an n-type GaAs substrate 1. Double heterostructure is made up to have a forward mesa like ridge having the width of 6mum and a thin high resistive AlGaAs buried layer 6 and a high resistive GaAs photoabsorption layer 7 are formed at the side faces of the ridge. As the side faces of the GaInP active layer 3 have forbidden band widths broader than those of GaInP and are covered with the AlGaAs buried layer 6 that has a low refractive index but has a high resistance, electric current together with light are confined in the GaInP active layer 3. However, as the ridge is formed into the forward mesa like shape, the neighborhood of both ends of the active layer 3 has a thin p-type AlGaInP clad layer 4 and then, lower slopes of light distribution are placed on the high resistive GaAs photo-absorption layer 7. Its photoabsorption, therefore, enables a higher order transverse mode to perform suppressed single transverse mode oscillations, even though its ridge width becomes wider.
