Title: Advanced method for water treatment
Inventor: MORI YOSHIHIKO
IPC: C02F1/52
Filed: 1998-09-04
Abstract: PROBLEM TO BE SOLVED: To provide an advanced method for treating sewage and waste water capable of obtaining water quality sufficient to reutilize sewage or waste water, capable of keeping high filtering flux for a long time and requiring a wide arranging place. SOLUTION: After a flocculant and ozone are added to raw water 1 comprising sewage secondary treated water or factory waste water, this raw water is filtered by an ozone-resistant membrane. At a time of the addition of the flocculant, if necessary, pH may be adjusted. Further, residual ozone is neutralized if necessary and, thereafter, filtered water is subjected to reverse osmosis membrane treatment 6 by a reverse osmosis membrane. By this constitution, since sewage secondary treated water or factory waste water can be highly treated, the treated water can be discharged to rivers as it is or reutilized. By filtering the raw water by the ozone-resistant membrane after the addition of the flocculant and ozone, a high filter flux is obtained by the addition of a reduced addition amt. of ozone and economical effect is obtained.

Title: Semiconductor laser device
Inventor: HINO ISAO
IPC: H01S5/323
Filed: 1986-10-22
Abstract: PURPOSE:To reduce the thermal resistance of the title device and to improve its characteristics and reliability by avoiding the use of a material, whose grating constant is sensitive to the composition, by a method wherein a self-positioning striped structure (SAS) is constituted u ing an AlGaAs layer as a layer for coating without using a material layer for forming a double hetero structure. CONSTITUTION:When an AlxGa1-x layer having a composition of Al of X approx.>0.5 is used as a p-type Al0.7Ga0.3As coating layer 6, a carrier confinement into an undoped Ga0.5In0.5P active layer 3 is performed by a thin layer of a thickness of 0.1-0.3 mum or thereabouts using this layer as a p-type (Al0.4Ga0.6)0.5 In0.5P clad layer 4 and an optical confinement is performed by both of the clad layer and the coating layer. In the case of AlGaAs, as the grating constant does not rely almost on the composition, the lattice matching property with an n-type GaAs substrate 1 is maintained even though the composition is shifted, and also, an element which does not damage a superior effect to the control of a transverse mode in an SAS can be realized. Moreover, as the thermal resistance of the AlGaAs layer having a composition of Al of X approx.>0.5 is 8-1 deg.C.cm/W and small, AlGaInP is made as thin as possible about each layer above the active layer 3 and is substituted by an AlGaAs system. Thereby, the thermal resistance of the device can be reduced.
