Title: Biological denitrification and dephosphorization of waste water
Inventor: TOUYA TAISUKE
IPC: C02F3/34
Filed: 1978-11-30
Abstract: PURPOSE: To perform denitrification and dephosphorization in the same process by a method wherein numbers of the process consisting of anaerobic nitrification and denitrification processes are connected in series and raw water is devided to be injected each of denitrification and anaerobic processes except the final denitrification process.  
     CONSTITUTION: Raw water containing nitrogen and phosphorous is passed through the inlet pipe 1 and devided to be injected into the anaerobic tank D x  and the downstream denitrification tanks D 1 WD n-1  (except the final denitrification tank D n ). From the final sedimentation tank S, concentrated and separated active sludge is returned through the sludge pipe 2. Depending on the concentration ratio of nitrogen and phosphorus containined in the raw water, the active sludge may be sent through the pipes 3, 4 to either the anaerobic tank D x  or the raw water feed pipe. In the nitrification tanks N 1 WN n , phosphate dissolved in the raw water is biologically taken in excessive amount under an aerobic condition. The raw water from which nitrogen and phosphrous are completely removed is finally sent to the final sedimentation tank S where solid and liquid are separated and discharged for flowing.

Title: Extinguishing circuit of gate turn-off thyristor
Inventor: KAGA ATSUSHI
IPC: H03K17/732
Filed: 1982-08-24
Abstract: PURPOSE:To prevent the destruction of a gate turn-off thyristor (GTO), by stopping the generation of pulses when a turn-off gate pulse required for extinction of arc of the GTO cannot be generated. CONSTITUTION:A transistor (TR) 6 is turned on and off in accordance with the output pulse signal of a turn-off pulse generating circuit 20. When the TR6 is turned on, a capacitor 3 is discharged. The discharge current is given to a GTO1 through a pulse transformer 8 to extinguish the GTO1. When the period of the output pulse signal of the turn-off pulse generating circuit 20 becomes shorter, a holding circuit 22 issues the output to turn on a TR23. As the result, the base of the TR6 is grounded to stop the discharging of the capacitor 3. Consequently, incomplete extinction of arc is prevented when the electric charge quantity required for extinction of arc is not stored because of deficient charging of the capacitor 3, and thus, the destruction of the GTO is prevented.

IPC: A61M5/145
Filed: 1999-05-27
Abstract: PROBLEM TO BE SOLVED: To further improve the safety of an embedment type injection pump having additional diaphragms for bolus injection. SOLUTION: The embedment type device for administration of a working fluid, more particularly a drug, has a chamber 3 for accepting the working fluid to be administered and a chamber 9 for accepting the working fluid bolus. Both chambers respectively have ports 6, 12 closed by the diaphragms 5, 11. An injection pipeline 8 communicating with an injection section is connected to an outlet 7 of the drug chamber 3. A supply pipeline 13 branched from the injection pipeline 8 is connected to the working fluid bolus accepting chamber 9. The supply pipeline 13 is internally provided with a mechanism 14 which opens a flow passage arriving at the injection section only when the working fluid bolus is supplied at a pressure higher than the prescribed min. pressure.  The occurrence of a condition to endanger the life by the sudden administration of a large amt. of the working fluid when the working fluid is kept supplied at all times only by the pressure lower than the min. pressure under which the flow passage is opened in order to replenish the drug storage section is eliminated. Even if the diaphragm of the drug storage section is mistaken with the diaphragm for the bolus injection, the liquid connecting path between the bolus injection chamber and the injection section is not held open and, therefore, the working fluid is not administrated.

Title: Liquid surface monitor for petroleum tank or the like
Inventor: KITAGOSHI SADAAKI
IPC: G01F23/292
Filed: 1980-10-24
Abstract: PURPOSE:To perform remote monitoring of the liquid surface by a monitor wherein plural pairs of light emitting elements and light receiving elements are disposed facing each other with two sides of a triangular hollow glass tube between, thereby to detect whether there exists an incident light to the light receiving element or not due to the presence or absence of liquid in the glass tube. CONSTITUTION:A triangular hollow glass tube 1 open at its upper and lower ends is inserted and disposed at the center of cylindrical glass 4 of a given length. Plural pairs of light emitting elements 2 and light receiving elements 3 are disposed facing each other with two sides of the glass tube 1 between at a given interval in the vertical direction. When a current is passed through the light emitting element 2 via a resistor R1 to illuminate the element 2, the emitted light enters into the light receiving element 3 and a current is passed through a resistor R2 in the state that there exists no liquid in the glass tube 1 at that level. In this case a transistor TR1 is conducted and a transistor TR2 is turned OFF, so that an indicating lamp 7 is not illuminated. When liquid is filled in the glass tube 1 at that level and the emitted light is interrupted, the TR1 is turned OFF and the TR2 is turned ON, so that the indicating lamp 7 is illuminated. Thus, it becomes possible to perform remote monitoring of the liquid surface.

Title: Method for controlling rear wheel steering device
Inventor: TAKAHASHI AKIRA
IPC: B62D137/00
Filed: 1993-06-21
Abstract: PURPOSE:To surely prevent the spin or the like of a vehicle in turning and braking operation by making the increased correction of the yaw rate coefficient by the acceleration coefficient to be set according to the negative longitudinal acceleration in the braking operation and the jerk coefficient to be set not more than the set value of the differentiated value of the negative longitudinal acceleration. CONSTITUTION:When a sudden brake is applied during the turning operation, the negative longitudinal acceleration (-a) becomes a constant small value until a vehicle is stopped, and its differentiated value (-j) is rapidly reduced in the beginning of the braking. Thus, the acceleration coefficient Ka and the jerk coefficient Kj become positive large values in the beginning of the braking, and the yaw rate coefficient kgamma is corrected to be increased. Though the rear wheel steering angle Er is largely steered instantaneously in the direction of the same phase irrespective of the reduction of the vehicle speed, and the cornering force of the rear wheels is reinforced. This constitution suppresses the swing-out of the rear wheels and prevents the roll-in of the vehicle and the rapid change of the spin behavior even if a large turning moment caused by the inertia force in the rapid braking during the turning operation is applied to the vehicle.
