Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To obtain high phosphorus removing performance by designing a device equipped with an anaerobic tank, contact aeration tank and precipitation tank and supplying iron ion or aluminum ion in the lower part of the contact aeration tank. SOLUTION: In anaerobic tanks 1, 4, org. matters are anaerobically decomposed by anaerobic microorganisms and org. nitrogen is anaerobically decomposed into ammonia nitrogen. In a contact aeration tank 7, decomposition of the org. matters is accelerated by aerobic microorganisms, while a polluted water is maintained in an aerobic state to decompose the ammonia nitrogen into nitric or nitrous nitrogen. In a precipitation tank 11, the water subjected to aerobic decomposition in the contact aeration tank 7 is divided into a precipitate and a supernatant. An eluting tank 16 is attached in the course of a return passage 17 to return the supernatant of the polluted water in the contact aeration tank 7 to the bottom, and a DC current is applied on iron electrodes to supply iron ion to the polluted water.  Thereby, the dephosphorizing performance can be improved without decreasing the treating performance by influences on microorganisms.

Filed: 1991-03-28
Abstract: PURPOSE:To minimize a fluctuation according to each low temperature setting and stabilize temperature by supplying coolant to a coolant reservoir at specified time intervals via a controller for each temperature setting in controlling temperature of a heating furnace. CONSTITUTION:At the time of measurement, if a liquid level of coolant 4 is at a certain level or lower due to influence of ambient temperature of a coolant reservoir 3, its rate of change, etc., a liquid level sensor 5 activates to supply power to a heater 9a of a heater siphon 9 of a coolant storage tank 6. This heat vaporizes a part of the coolant 4 in the tank 6, and pressure is applied to inside the tank 6, so that the coolant 4 is fed to the coolant reservoir 3 by differential pressure from an atmospheric pressure. The coolant 4 in the coolant reservoir 3 reaches a set level of the liquid level sensor 5, whereby a controller 10 stops supplying power to the heater 9a and also opens a solenoid valve 8 to stop supplying the coolant 4. This is repeated to maintain the coolant 4 in the coolant reservoir 3 at a constant level. Therefore, in any low temperature set region with a speed of raising/lowering temperature differed, a stable liquid level can be secured.

Title: Digital signal delay circuit
Inventor: MUROOKA TAKAHIRO
IPC: H03K5/133
Filed: 1990-04-06
Abstract: PURPOSE:To constitute all circuits of MOS transistors(TRs) by providing a means controlling driving capability of the circuit depending on the quantity of an analog signal to control a delay and a protection means preventing extreme reduction in the driving capability to a variable delay means. CONSTITUTION:An input signal Cin is delayed by 2 sets of variable delay circuits 3a, 3b and comes to a delayed signal dCin. Then the phase of the signal dCin is compared for its lead or lay with the phase of the innerse of the iCin of the input signal Cin by a phase comparator circuit 4. When the delay in the signal dCin is deficient, since the phase comparator circuit 4 fetches the signal dCin delayed by the inverting signal iCin, the holding output Q is outputted as an H level and the inverse of the output Q is outputted as an L level at the time of stating the signal iCin. Moreover, when the delay is too large, the holding output Q is outputted as an L level and the inverse of the output Q is outputted as an H level conversely. Thus, the fluctuation in the delay is small and stable circuit operation is attained.
