Title: Aldehyde-based surfactant and treatment of waste water from industrial, commercial and public facility
Inventor: DENISU KURISUTEIN GIYARANTEI
IPC: C02F1/52
Filed: 1996-05-10
Abstract: PROBLEM TO BE SOLVED: To improve the purifying property of waste water when removing impurities associated with a splitting, nonionic surfactant in an aqueous flow by adjusting pH of the aqueous flow to acidic pH so that surfactant may be irreversibly split into a water insoluble fraction and a water soluble fraction and removing a water insoluble phase from the aqueous flow.  
     SOLUTION: In the case of purifying waste water, pH of an aqueous flow is adjusted to sufficiently acidic pH so that a surfactant may be split into a relatively water insoluble fraction and a relatively water soluble fraction. In this way, impurities are released from the association with the surfactant, and a water insoluble phase including the released impurities is formed, and treatment is made so as to separate it from the aqueous flow. In this case, the splitting nonionic surfactant is that represented by any one of the formulas I, II or a mixture thereof. In the formulas, R is hydrogen, R' is a residual group of organic compounds derived from aldehyde having the formula III (R is hydrogen, R' is a residual group of organic compounds having about 8-20 total carbon atoms), X is hydrogen or the like, and Y and Z are hydrogen, methyl or the like.

Further, the sheet Pa discharged into the discharge section 4, is automatically led into a paper feed section 3 in such a condition that the trailing end of the sheet Pa on discharge is turned into the leading end of the sheet Pa, and a sheet detecting switch 19 is actuated. With this arrangement, the paper feed roller 20 initiates its rotation so that the sheet Pa is again taken into a U-turn conveying path 13 to complete bisurface copying operation. After successively copying one side surfaces of sheets, the above-mentioned operation is carried out, thereby it is possible to carry out bisurface copying operation by a large amount.

Title: Formation of thin film

Filed: 1983-08-23
Abstract: PURPOSE:To form a thin film of superior quality having no layer containing impurity atoms at an interface by a method wherein gas containing halogen group atoms is added by the specified quantity to reaction gas and supplied. CONSTITUTION:When reaction gas in a plasma condition is to be supplied into a reaction chamber to form a thin film on the surface of a semiconductor substrate arrange in the reaction chamber, gas containing halogen group atoms is added 5-30% by the ratio of flow rates to reaction gas and supplied. Ammonia gas is flowed in a quartz reaction tube, and gas is made to a plasma condition under reduced pressure of 1 Torr or less, for example. CHF3 gas is added by the ratio of flow rates mentioned above as a reaction accelerator at the same time when ammonia gas is flowed into the reaction tube, and the silicon substrate arranted in the reaction tube is nitrified in plasma of mixed gas with ammonia gas. Accordingly, impurity atoms of oxygen, etc. stored at the boundary face between the semiconductor substrate and a reactively formed thin film are removed or reduced. Therefore a process to remove the impurity atoms at the boundary face is made unnecessarily, and the thin film formation method thereof is effective for enhancement of reliability and enhancement of efficiency.
