Title: Treatment of drained water containing ammonia nitrogen
Inventor: SHISHIDA KENICHI
IPC: C02F1/74
Filed: 1994-01-21
Abstract: PURPOSE:To ensure that ammonia nitrogen can be efficiently treated by allowing drained water to come into contact with a gas containing ozone, using a specified solid catalyst, in the presence of bromide ion and under the effect of a pressure causing the drained water to maintain a liquid phase. CONSTITUTION:A treatment method for a drained water containing ammonia nitrogen is used for treating a secondary treated sewage, a secondary treated excretion water, industrial drained water or its secondary treated water or various types of drained water containing ammonia nitrogen from a fish culture pond. When removing ammonia nitrogen contained in the drained water, bromide ion is allowed to be present in the drained water under the effect of a pressure to maintain the drained water in a liquid phase at 0 to 100 deg.C, and the drained water is caused to flow into a reaction pipe 2 by a pump 3 through a line 7. On the other hand, a gas containing the ozone generated by an ozone generator 4 is caused to come into contact with the drained water using a flow rate valve 5 and run through the reaction pipe 2. A solid catalyst 1 contains at least, one type of element selected from among titanium, silicon, zirconium, aluminum, zinc, tin, iron, manganese, cobalt and nickel and/or the chemical compound of the element.

Title: Constant current circuit
Inventor: SUZUKI NOBUYUKI
IPC: G05F3/30
Filed: 1987-01-13
Abstract: PURPOSE:To obtain a constant current with high accuracy, by utilizing a band gap reference type reference voltage source. CONSTITUTION:When a voltage is impressed on a power source voltage line VCC, the base and the collector potentials of an NPN transistor NTr15 form a one diode voltage drop part. On the collector of an NTr14, the current smaller than that of the NTr15 flows. Also, on a PNP transistor PTr11, the same current as the collector current of the NTr14 flows, then, the voltage between the base and the emitter of the PTr11 is decided. The current of the PTr11 is shifted to a PTr10, then, it flows into an NTr16. The base and the collector potential of the NTr16 goes to a value higher by one diode voltage than the voltage V of the reference voltage source 9, and is impressed on the base of an NTr13, and since it is higher than the NTr14, the NTr14 is switched to a cut off state, and the current with the value in which the emitter potential of the NTr13 is divided by a resistor 17 flows on the collector of the NTr13, and the collector current of the PTr11 goes to the constant current similarly as the PTr12. In such a way, it is possible to obtain the constant current with high accuracy.

Title: Combustion finishing point detecting device
Inventor: ONO HIDETAKA
IPC: F23G5/50
Filed: 1983-01-17
Abstract: PURPOSE:To reduce erroneous operation, provide a device capable of resisting noise and enable a high speed operation by a method wherein a point where a brightness value or a rate of variation of brightness becomes a predetermined value is detected as a combustion finishing point. CONSTITUTION:When an incinerater H is observed through an industrial television (ITV), it shows that a high voltage is found in a combustion zone Q due to a flame of high brightness and a low voltage is found in an ash zone R. When voltages corresponding to one scan line are integrated, a mean brightness at the position can be calculated. In order to calculate the position of combustion finishing point P, a slice level of brightness is specified by a parameter and a distance showing the specified brightness may be found. Therefore, since a sensing parameter is based on one brightness level, the processing is easy and few erroneous operation is made. The brightness signal is made to show its mean value, so that the device is capable of enduring electrical or image noises.
