Title: Biosludge concentration device
Inventor: MIHASHI KAORU
IPC: B01D29/27
Filed: 1987-11-30
Abstract: PURPOSE:To contrive sludge concentration at low cost by mounting a filter bag container with a filtered water outflow port at the bottom and an external circumferential surface formed at the place where it comes into contact with a panel surface, on the panel surface and accommodating a filter bag which touches under pressure the internal circumferential surface of the container due to a water pressure of a mixed liquid of sludge to be accommodated. CONSTITUTION:On a flat panel surface 1 which is so designed as to allow recovery or release of filtered water, a filter bag container 2 with a filtered water outflow port 3 and the external circumferential surface formed at the place where it touches the panel surface 1, is mounted. Further, a filter bag 5 with coarse meshes which comes into contact with a slight gap (g) left with the internal circumferential surface and the internal bottom surface of the container 2 by water pressure of a mixed liquid of sludge 6 to be accommodated, is stored in the container 2 in a detachable manner. The flow velocity of transmission of the filtered water from the filter bag 5 into the slight gap (g) is controlled by a contact action to the internal circumferential surface and the internal bottom surface of the container 2 when the mixed liquid of sludge is accommodated. Furthermore, the contact part comes in contact with the panel surface 1 under pressure by a load to control the flow velocity of outflow of the filtered water from the external circumferential surface at the bottom of the container 2. As a result, sludge is concentrated with little labor and maintenance cost.

Title: Optical waveguide element
Inventor: MIURA SHIGEAKI
IPC: G02B6/34
Filed: 1993-12-03
Abstract: PURPOSE:To facilitate the formation of an optical waveguide element formed to weaken the higher order diffracted light each other by imparting a specific distribution to the refractive index of a clad layer by expanding the permissible range of the thickness of the clad layer. CONSTITUTION:The refractive index nc1 on the substrate 10 side increases and the refractive index nc2 on the air side decreases when the prescribed- distribution is imparted to the refractive index nc of the clad layer 15. The exit angle of the higher order diffracted light emitted to the clad layer 11 side increases and the exit light quantity decreases if the refractive index nc1 on the substrate 10 side is larger in such a manner. Since the higher order diffracted light emitted to the substrate 10 side and the higher order diffracted light emitted and reflected to the clad layer 15 side weaken each other and, therefore, if the quantity of the higher order diffracted light emitted to the clad layer 15 side is originally low, the total light quantity of the higher order diffracted light progressing to the substrate 10 side is suppressed to a relatively low level and the degradation in the power distribution ratio of the primary diffracted light 21 is relatively lessened even if the thickness of the clad layer deviates from the design value and the weakening each other is ideally executed.
