Abstract: PURPOSE:To perform stable and effective treatment without the formation of bulking, by specifying the constitution of an aerating tank for mixing waste water with activated sludge and sequentially carrying the mixture, and the concentration of nitrate nitrogen in the activated sludge-mixed liquid inside the foremost aerating chamber. CONSTITUTION:Waste water to be treated is mixed with activated sludge and aerated by sending it through a passage 1 to the foremost chamber 2 of an aerating tank equally divided into 6 or more parts, e.g. 2-7. Said water is then sequentially aerated in the chambers 3-7 and introduced into a precipitating tank 8. The purified water is drained from the tank 8 through a passage 9, while precipitating sludge in the tank 8 is returned through a returning passage 10 to the chamber 2. The aeration in each of the chambers is performed by O2- contg. gas such as air from a blower 11. Hereon, the treatment is performed while holding the concentration of nitrate nitrogen in the activated sludge-mixed liquid inside the chamber 2 above 20mg/l at any times. When said concentration is insufficient, nitric acid or a nitrate is added from a reservoir 13.

Title: Method for recording and erasing optical information
Inventor: YAMADA NOBORU
IPC: G11B7/127
Filed: 1984-04-27
Abstract: PURPOSE:To enable complete recording and erasing by using a recording medium whose optical constant is decreased by heating and rapid cooling and increased by heating and slow cooling. CONSTITUTION:A recording medium whose optical constant is changed before and after recording is used. The optical constant is decreased by heating and rapid cooling, resulting in a decrease in the reflectance and an increase in the transmittance, and it is increased by heating and slow cooling, resulting in an increase in the reflectance and a decrease in the transmittance. For example, a thin chalcogenide glass film or a TeOx-base thin film is formed on a substrate such as a glass or plastic sheet by vapor deposition, sputtering or other method to obtain the recording medium. When information is recorded, light is irradiated with high power to melt the irradiated part, and the part is rapidly cooled. When the recorded information is erased, light is irradiated with high power to melt the irradiated part, the power is reduced at once, and the part is slowly cooled while irradiating light with low power.

Title: Filter for receiving
Inventor: SEKIGUCHI NOBUO
IPC: H04B1/40
Filed: 1982-05-25
Abstract: PURPOSE:To prevent transmission power from straying into a receiving system at transmission, by connecting an inductance element and a switching element between a signal circuit and a common circuit (ground). CONSTITUTION:An input terminal ''in'' is connected to a switch for transmission/ reception changeover and an output terminal ''out'' is connected to the receiving system. A forward bias is given to a control terminal ''ct'' at receiving to turn on a transistor (TR) Q11, and a prescribed frequency is coupled to the receiving system by means of capacitors C11, C12 and an inductance L11. Since the TRQ11 is controlled to be truned off at transmission and the collector capacitance of the TRQ11 is inserted in series with the inductance L11, the passing frequency is changed remarkably and the input terminal ''in'' and the output terminal ''out'' are interrupted apparently.
