Title: Muddy water filtering method
Inventor: FUKAYA MINORU
IPC: B01D37/02
Filed: 1995-03-20
Abstract: PURPOSE: To effectively utilize sludge incineration ash and to reduce the filtering treatment cost of muddy water by using sludge incineration ash as a filtering aid and addint the same to muddy water to perform filtering. CONSTITUTION: Lime or a polymeric flocculant is added to sludge generated by the activated sludge treatment of waste water to flocculate the sludge and the flocculated sludge is dehydrated to a certain degree if desired and subsequently incinerated to obtain sludge incineration ash being alkaline sludge incineration ash. When this sludge incineration ash is added to muddy water, fine particles are associated to form large particles and, when this muddy water is filtered, large particles form water passages in the cake accumulated in a filter chamber along with sludge incineration ash particles and filtering efficiency is enhanced. By this method, muddy water is treated extremely inexpensively. The addition amt. of sludge incineration ash is desirably about 60g/l or less. This filtering method is suitable for muddy water, for example, generated from a shield construction method.

IPC: G01R27/02
Filed: 1981-06-08
Abstract: PURPOSE:To measure resistance value of a plurality of resistors with high accuracy continuously, by connecting a capacitor and an NOT circuit in series alternately and connecting a power supply to an input terminal of each NOT circuit via a measured resistance. CONSTITUTION:When a microcomputer 16 outputs a rectangular wave, this rectangular wave is inverted at an NOT circuit 22 and inputted to a capacitor 10A, then the input terminal (c) of the NOT circuit 12A has a voltage drop once and the capacitor is being charged with charged supplies from a resistor 14A. Thus, a voltage which is at high level for a time of charging until the capacitor 10A is charged up to the threshold value, appears at an output terminal (d). This voltage change is inputted to the microcomputer 16 and a resistance value of the resistor 14A is calculated. On the other hand, the output of the output terminal (d) becomes a start signal of a next capacitor 10B, and resistance values for resistors 14b,... are obtained similarly, and the result of calculations is printed out on a printer 20 via an interface 18.

IPC: H01L21/336
Filed: 1983-05-19
Abstract: PURPOSE:To enable to stabilize the threshold voltage by a method wherein the second impurity region of the same conductivity type a that of the semiconductor substrate is formed in the first semiconductor region by leaving an insulation film only on the side surface of a poly Si gate electrode. CONSTITUTION:The zero impurity region 3 of the conductivity type reverse to that of the substrate 1 and a gate oxide film 5 are formed. The poly Si gate electrodes 6a and 6b are formed, the first impurity region 7 of the condutivity type reverse to that of the substrate 1 is formed with said electrodes as a mask, and the insulation film 12 is grown and etched. Since this sputter etching has the ratio of vertical and transversal etching at several ten or more, the insulation films 12a and 12b on the side surface of the poly Si's remain. When the second impurity region 8 of the same conductivity type as that of the substrate 1 is formed with said electrodes 6a and 6b and insulation films 12a and 12b as a mask, the diffusion positions of the first impurity region 7 and the second one 8 become B and C, respectively, resulting in slippage by the thickness (t) of the insulation film. Therefore, the part of gentle profile of said region 7 intersects the second one 8, and accordingly the threshold voltage stabilizes.
