Abstract: PURPOSE:To remove the materials in waste water which are hard to be biologically decomposed at a high rate of removal even if said materials are contained in high concn. and to obtain good treated water by removing the materials flocculated by limiting the pH of the waste water then allowing remaining org. materials to be digested by algae. CONSTITUTION:If the pH of waste water contg. materials which are hard to be biologically decomposed is controlled to <=3, the most of the humic acid among said materials flocculate and settle because the humic acid is acid insoluble. The precipitate thereof is subjected to solid-liquid sepn. Since the separated liquid still contains acid soluble materials which are hard to be decomposed such as fulvic acid, the separated liquid is neutralized, whereafter algae are inoculated thereto and are cultured under irradiation of solar light or artificial light. The cultured algae are removed. The algae are blue algae, euglena and green algae, etc. Although the solid-liquid sepn. of the algae can be accomplished by centrifugal sepn., etc., it is possible to flocculate the org. materials remaining in the treated water simultaneously if the algae are flocculated and settled with flocculating agents of Al salt, iron salt, etc.

Title: Optical amplifier
Inventor: SHIBANO FUMIHIKO
IPC: H01S3/06
Filed: 1990-02-16
Abstract: PURPOSE:To make it possible to obtain a high gain inspective of its small size by allowing signal light to enter etalon at a specified angle and perform multiple reflection within the etalon. CONSTITUTION:An etalon is formed into a rectangular parallelopied made of laser amplification acting medium. The top and bottom of the etalon are coated with reflection films 2 and 3, such as metal films placed in parallel to each other. The reflection films 2 and 3 are not formed on a region 4 and a region 5 near the ends. Pumping light 6 with constant intensity is arranged to enter the etalon 1 from the end near the region 4 and signal light 7 further enters the etalon 1 at an incidence angle 0 from the region 4 on the top. Therefore, being reflected with the reflection films 2 and 3 in the etalon 1, the signal light 7 advances therethrough and the light is amplified with the pumping light 6 so that the amplified signal light may be taken out a output light 8 from the region 5. In this manner, multiple reflection between the reflection films 2 and 3 extends the length of optical pass and provides a high gain in spite of its small size.
