Title: Method for purifying low concentration organic sewage by utilizing humus substance
Inventor: KUSUNOKI YASUNORI
IPC: C02F3/06
Filed: 1986-04-15
Abstract: PURPOSE:To purify many kinds of sewages, by combining an oxidation treatment process using an oxidizing agent consisting of activated humus and zeolite with an anaerobic reducing treatment process. CONSTITUTION:Raw water of low concn. org. sewage pumped up from the receiving port 9 of a purifying tank to be supplied in an oxidizing unit 1 falls through a falling recirculation passage 3 and rises through an oxidizing agent case 2 by air bubbles rising from an air diffusion pipe 8 and falls through the falling recirculation passage 3 to form a recirculation stream. Sewage is contacted with an oxidizing agent during the recirculation of the raw water of the sewage to form SS. Heavy SS formed is sedimented to be transferred onto an inclined bottom surface 10 and enters the bottom part of a sedimentation chamber 5 to be discharged from a discharge port 11. A supernatant liquid enters a second oxidizing unit 20 and formed SS is discharged from a discharge port 23 while the supernatant liquid passes through the sedimentation chamber 5 to rise and is discharged from a discharge port 24.

Abstract: PROBLEM TO BE SOLVED: To unnecessitate a special operation and to efficiently prepare a document arrangement by which a paragraph divided document, etc., is easy to be seen by automatically starting a new line for the succeeding character string including specified data when it is judged that the specified character data exists in document data. SOLUTION: In the same line within a document memory 16-1 in which the pertinent character string within a character string register 16-3 is included, whether character data is stored at the figure location on the left side or not is checked. When the character data exists on the left side of the same line of the pertinent character string, a new line is started for the sentence following the pertinent character string and the sentence following the character string is moved up to the figure location within a figure location register 16-4. As a result, the character string is moved and is displayed on the next line. Therefore, the figure locations of an inputted character string and a new inputted character string this time are automatically made the same. As a result, document data can be autcmatically arranged so that the data may be easy to be seen.

Therewith the control signal becomes at Hi level, and the switch SW is put on, and the transistor Q2 is turned on. Now it is possible to start the oscillating motion of the inverter device in synchronization with the timing at which the control signal turns from Lo to Hi level. Thus the duty dimming can be performed in accordance with the control signals for dimming.

Abstract: PURPOSE:To obtain a paint film of good adhesion in a simple manner, by pretreating the surface of a polyamide molding with a cationic surfactant, and coating the pretreated molding with an aminoalkyd resin paint. CONSTITUTION:In a pretreatment, a cationic surfactant is applied to the coating surface of a polyamide molding. An amino-alkyl resin paint is then applied thereto. Essentially, an aminoalkyd resin paint can hardly adhere to a polyamide resin, and therefore, use has been made of, for eample, a method for improving the adhesion of a polyamide resin by immersing it in a 40% aqueous phosphoric acid solution and washing it with water, but this method has a problem of dimensional change due to absorption of water, etc., in addition to its complicatedness. It becomes possible to obtain a paint film excellent in adhesion, gloss, feeling of thickness, hardness, weather resistance, solvent resistance, etc., by the pretreatment with a cationic surfactant, and it is suitable for painting car trims or the like.
