IPC: C02F1/40
Filed: 1986-06-20
Abstract: PURPOSE:To enhance the separation efficiency of an oil component, by providing an oil-water separation chamber by providing a partition plate partitioning a waste water surface layer part to a waste water inflow part and arranging a float oil-water pumping-up machine in the oil-water separation chamber. CONSTITUTION:The waste water flows in from a waste water port 2 and the waste water surface layer part thereof is introduced into an oil-water separation chamber 1b by a flow passage altering plate 3 and the waste water lower layer part in a waste water inflow part 1a directly flows into a drain channel 1. Since the oil component in waste water flowing in the waste water inflow part 1a from a drain port 2 floats, the lower part of the flow passage altering plate 3 is arranged under the surface of waste water so as to reach a proper depth. By this constitution, the oil component in the waste water within the waste water inflow part 1a is contained in the waste water surface layer part to be introduced into the oil-water separation chamber 1b and prevented from directly flowing into the drain channel 1. The float oil is moved to a pumping-up machine 6 by a drift fan 7 to be pumped up by said pumping-up machine 6. By this method, the oil component is separated and recovered efficiently.

Filed: 1988-06-10
Abstract: PURPOSE:To reduce the X-ray exposure quantity by detecting a fluoroscopic table or the shift quantity of an image system and changing the X-ray pulse interval based on the detection signal. CONSTITUTION:When a fluoroscopic table is moved, a rotor is rotated to detect the shift of the table 12.
