Abstract: PURPOSE:To permit the outflow of NH4-N into treated water by measuring or predicting the temp. and nitrogen load fluctuation of the sewage in a cleaning-up tank to permit the adjustment of the circulating flow rate in the cleaning-up tank so that the nitration rate of a catalyst material can be controlled to the rate always slightly higher than the load. CONSTITUTION:The catalyst material 2 on which microorganisms are stuck and grown is installed in the sewage in the cleaning-up tank 1. The air delivered from an air diffusion blower 8 is supplied into the sewage in the tank 1 to form the circulating flow passing on the surface of the contact material by which the ammoniac nitrogen in the sewage is nitrated to nitrite nitrogen or nitrate nitrogen. The output signals from a temp. measuring means 15 and air flow rate measuring means 18 and the preliminarily inputted relation among the water temp., circulating speed and nitration speed are compared and calculated in an arithmetic control means 17 of the above-mentioned sewage cleaning-up device. The flow rate of the air to be delivered from the blower 8 is controlled by the output signal from the means 17 in an inverter 21, by which the air diffusing and stirring capacity in the tank 1 is adjusted and the nitration capacity is controlled.

Abstract: PURPOSE:To enable the mischievous influence of the runaway or the like of a wind tunnel operation caused by the breakdown of a CPU or a service interruption to be surely prevented by detecting the interruption of relief pulses for controlling the operation steps of the CPU. CONSTITUTION:In case of a service interruption in draft or the breakdown of a CPU, the hold of AC 100V is 'released' and the supply of a high oil pressure to a control function in a normal condition is stopped. A relay 16 detects the service interruption and contacts 29 and 30 are turned to 'on' and 'off', respectively, on one hand. On the other hand, the present angle changing position is recognized by limit switches 21 and 22 provided in an angle changing mechanism and either of relays 27 and 28 is operated. Accordingly, by operating either of electromagnetic valve 23 and 24, the angle changing mechanism starts to move in a direction wherein an angle is equal to zero. When a model reaches a zero angle range, an interlock constituted by relays 30-32 is 'released' and DC 24V is 'cut'. Accordingly, electromagnetic valves 25 and 26 are turned to 'off' and the high oil pressure is applied to the quick closure side of a pressure control valve and a cut-off valve whereby a wind tunnel is quickly stopped.
