Title: Treating method for excess sludge
Inventor: IWABE HIDEKI
IPC: C02F11/00
Filed: 1995-03-06
Abstract: PURPOSE: To recover phosphorus by separating from sludge before final treatment of the sludge by a method wherein easily decomposable organic matter is mixed in excess sludge, the sludge is held for a suitable time under an anaerobic condition to cause phosphorus taken in the excess sludge to elute into a liquid phase, and the sludge is separated into solid and liquid to remove the separated liquid containing the phosphorus. CONSTITUTION: Excess sludge 4 generated from an anaerobic/aerobic tank 2 is charged into a mixing tank 5. Besides, a part of raw sludge 6 generated in a settling pond 1 is added into the mixing tank 5, and they are mixed by stirring. The mixed excess sludge 7 in the mixing tank 5 is transferred to a reacting tank 8, which is held for a suitable time under an anaerobic condition in the reacting tank 8, and the mixed excess sludge 7 is anaerobically digested. Further, phosphorus in the mixed excess sludge 7 is eluted into a liquid phase. Then, the mixed excess sludge 7 in the reacting tank 8 is transferred to a mechanical concentrator. Solid is separated from liquid mechanically by the concentrator 9, and concentrated excess sludge 10 and phosphorus- contained separated liquid 11, respectively are recovered to be removed.  Therefore, phosphorus can be recovered by separating from the sludge before a final treating process of the sludge.

Title: Driving circuit of ink jet head
Inventor: NOBUOKA ATSUSHI
IPC: B41J2/045
Filed: 1996-03-01
Abstract: PROBLEM TO BE SOLVED: To prevent a lowering of electric potential between electrodes of piezoelectric actuators by providing a charging transistor at every piezoelectrio actuator and turning on the charging transistors during a period when the electric potential of the piezoelectric actuators is not controlled by a driving piezoelectric control circuit, and connecting the piezoelectric actuators to a constant-voltage source. SOLUTION: In a piezoelectric actuator driving circuit 100n corresponding to a nozzle which does not discharge ink drops, charging and discharging transistor drive signals become low, and a discharging transistor 104n becomes an OFF state and a charging transistor 105n becomes an ON state. At this time, though a piezoelectric actuator 101n begins to discharge an accumulated electrical charge through an insulation resistance of itself, an electric potential between electrodes of the piezoelectric actuator 101n does not lower below a partial pressure to be decided by the insulation resistance and a value of a resistance 103n, because it is connected to a constant-voltage source through the charging transistor 105n and the resistance 103n. Accordingly, the piezoelectric actuator 101n holds a displacement almost the same as an initial state.

Outdoor air is sucked from an outdoor suction port 5 into an outdoor suction chamber 26 via a duct, and supplied into the chamber from indoor discharge port 6 by a supply air blower 11 by passing through a supply air passage 9 leading from a chamber 19 to a supply air blower chamber 24 via the heat exchanger 12, a chamber 18, and an opening 25, in this sequence. Upon this occasion, heat exchange is carried out between the exhaust air flow and the supply air flow, and the exhaust air heat is recovered to reduce the space heating or cooling load.

Title: Secondary air feeder for engine
Inventor: ICHINOMIYA TOORU
IPC: F01N3/10
Filed: 1978-04-17
Abstract: PURPOSE: To change the shut-off time of secondary air depending on the warming- up condition of an engine, by providing a passage which connects a second diaphragm chamber to a first diaphragm chamber into which the negative pressure of the intake pipe of the engine is introduced.  
     CONSTITUTION: A first orifice passage 33 always connects the first diaphragm chamber 28 and the second diaphragm chamber 30 to each other. A second orifice passage 34 is selectively opened or closed by a bimetal disc 35. When the temperature of the enine is low, the bimetal disc 35 is in pressural contact with an O-ring 37 so that the second orifice passage 34 is closed. When the temperature of the engine is higher than a predetermined level, the bimetal disc 35 is out of contact with the O-ring 37 so that the second orifice passage 34 is opened. Therefore, the opening and closing of a secondary air control valve is affected by the temperature. The shut-off time of secondary air during the deceleration of the engine is shortened according as the temperature of the engine rises.

Title: Controlling apparatus for air sending quantity of aerating tank
Inventor: WATANABE SHIYOUJI
IPC: C02F3/12
Filed: 1979-04-12
Abstract: PURPOSE: To enable the effective aerating treatment corresponding to an org. matter load by a method wherein CO 2  concn. within an exhaust gas of an aerating tank is detected and an air sending quantity is controlled by comparing the detected value to a set objective value.  
     CONSTITUTION: The waste water is flowed into an aerating tank 1 from a conduit 5 and subjected to the stirring treatment while activated sludge and air are introduced from a conduit 9, 11 respectively. The CO 2  concn. within an exhaust gas collecting instrument 3 is measured by a CO 2  concn. meter 20 and the measured value is applied to an operator 22 to be compared to an objective value C* preliminarily set by a setting instrument 24 and a deviation ε is calculated. Subsequently, an opening degree of an air quantity controlling value 28 is regulated corresponding to a value ε by the order of a regulating device 26 and an air of an optimum air quantity V c  is sent. Because the change of a CO 2  concn. corresponding to the change of org. matter load is more sensitive than the change of an O 2  gas concn. or DO, the control of an air sending quantity is correctly carried out.

Filed: 1989-02-28
Abstract: PURPOSE:To demonstrate superior resistance to corrosion in molten Al bath and molten Zu/Al bath by using iron-chrome alloy steel containing the specified volume of Cr, on which a ceramic film composed of Cr2O3 formed by heating Al2O3 particles and Cr2O3 aggregates is provided. CONSTITUTION:A base is iron-chrome alloy steel containing 3 - 50wt.% of Cr. A ceramic film composed of chrome oxide Cr2O3 formed by heating Al2O3 particles and chromic acid CrO3 as aggregates is provided over said base.

Thus, a ceramic coating material of superior resistance to corrosion in respective molten liquid of Al, Al alloy or Zu/Al alloy is provided, and a roll and Al and a mold for die casting to be used in molten Al plating bath and molten Zu/Al alloy plating bath to which said coating material is applied are manufactured.

An AC voltage is impressed on the terminals on one side of the magnetoresistance bodies, the terminals on the other side thereof are connected together respectively with respect to all of the magnetoresistance bodies, and a rotational angle is determined form a phase difference between an AC signal obtained at each connecting point and the impressed AC voltage.

Filed: 1984-03-09
Abstract: PURPOSE:To process at a high speed and to reduce the constitution of hardware by enlarging and reducing a picture by means of addition processing without multiplication. CONSTITUTION:An initial value setting means 50 initializes an arbitrary value with respect to a remainder register 52, which adds a remainder R held right now to a ratio alpha held by a ratio register 51 through an adder 53.

However, in a point S4 the carry detecting part 54 will not shift the result register 56, and simultaneously controls so as not to write a bit information (d) transmitted from the original picture register 55. In a point S5, a bit information (e) which is held again as an original picture information P5 is held as a shift information Q4 in the result register 56 by a control of the carry detecting part 54. Through the similar action, original picture data can be reduced to 6/8 in size.
