Abstract: PURPOSE:To attain an invariably stabilized removal performance of a biologically activated carbon by measuring the concentration of phosphoric acid in an untreated water to be introduced into the biologically activated carbon and feeding a solution of phosphoric acid into upstream the biologically activated carbon, when the concentration of phosphoric acid in the water being treated is not higher than a predetermined concentration. CONSTITUTION:After coagulating sedimentation of suspended matter in an untreated water and removal thereof by sand filtration, dissolved matter in the water is decomposed and deodorized by ozone and removed by a biologically activated carbon 4. The concentration of phosphoric acid in the untreated water to be introduced into the biologically activated carbon 4 is measured by a phosphoric acid concentration meter 6. Moreover, a phosphoric acid solution feeding device 7, upon reception of a signal from the phosphoric acid concentration meter 6, feeds the solution of phosphoric acid into upstream the biologically activated carbon 4, when the concentration of phosphoric acid in the water being treated is not higher than a predetermined concentration. As a result, despite a substantial decrease in the phosphoric acid contained in the surface water of rivers, lakes and marshes, dams, etc., from late spring to early summer, the removal performance of the biologically activated carbon can be almost invariably stabilized.

Title: Linear motor
Inventor: OSANAI EIJI
IPC: H02K41/02
Filed: 1986-12-18
Abstract: PURPOSE:To restrict the temperature rise of a coil by winding a pipeline for cooling around the coil for driving. CONSTITUTION:When a plurality of coils 2 is conducted while switching current, a movable piece 1 obtains a thrust and moves into the direction of linear motion. In this case, heat due to Joule's heat is generated in the coil 2 while the heat is transferred to fluid 10, flowing through the pipeline 3. The fluid 10, whose temperature has been risen by the transfer of the heat generated in the coil 2, is transported to a cooler 7 by a pump 6 through the pipeline 3. The cooler 7 deprives heat from the fluid 10, whose temperature has been risen, and the temperature of the fluid is reduced to a predetermined temperature. The predetermined temperature is determined by a control unit 9 based on the temperature of the coil 2, which is detected by a temperature sensor 8. The fluid 10, whose temperature is controlled at the predetermined temperature, is transported to the coil 2 again by the pump 6 through the pipeline 3. Accordingly, the temperature rise of the coil 2 may be restricted and a constant temperature may be maintained.

Filed: 1990-11-05
Abstract: PURPOSE:To prevent the generation of defective bonding by determining the surface of InSb crystal substrate, where antimony Sb is the atom of the most outside layer, as rear surface F2 and by regulating the direction of the rear surface in each process and bonding the surface to a support. CONSTITUTION:The In surface of InSb wafer W1 is determined as front surface F1 and the Sb surface thereof, as rear surface F2 and a mark (m) is put on the Sb surface in a stage where InSb ingot 1 is sliced off. Because the mark (m) disappears in a polishing process, the direction of handling is regulated lest the front and rear of the wafer should be reversed, when the wafer W1 is set on a polishing device and removed therefrom. Also, because a work is small in a dividing process, the form of handling and conveyance is selected especially lest the front and rear of the work should be reversed. In an etching process, the rear surface F2 is Sb surface so as to be finished into a mirror surface. In a submount process, the rear surface F2 side is always directed to a submount substrate 20. Thus, no bubble remains in an adhesive 25 so that a satisfactory bonded state is obtained.
