Title: Method for dephosphorylating waste water and device therefor
Inventor: YAMASHITA MASAHARU
IPC: C02F1/58
Filed: 1996-02-07
Abstract: PROBLEM TO BE SOLVED: To carry out an efficient dephosphorylating reaction by detecting a variation of a pH of a waste water in a reactor to control a pour of an alkali ion and also increasing and decreasing the pour of a magnesium ion in accordance with its pour. SOLUTION: The waste water containing an ammonium ion and a phosphate ion is flowed into a pH adjusting means 2 and its pH is measured with a pH indicating controller 13. Then an alkali soln. is supplied by actuating an injection pump 12a at an alkali injection line 12 so that an alkali component in the waste water flowed into a dephosphorylating reactor 1 may be almost constant. The waste water after adjusting the pH is sent to the dephosphorylating reactor 1 with a pump 6a and flowed into a tank body 1a by upward stream, and the alkali soln. and a magnesium soln. are continuously injected respectively from each injecting means 3 and 4 in a fixed injection ratio, and the phosphate ion and the ammonium ion are converted to magnesium ammonium phosphate and the phosphate is crystallized on a surface of MAP particles previously formed in the waste water.

Abstract: PROBLEM TO BE SOLVED: To hydrogenate a saccharide or its mixture into a sugaralcohol or a its mixture by reacting the saccharide or its mixture with hydrogen at a high temperature under a high pressure in the presence of a nickel-containing catalyst supported on a carrier. SOLUTION: A saccharide or a saccharide mixture selected from isomaltulose, trehalose, maltulose, leucrose and lactulose in an aqueous solution is hydrogenated with hydrogen in the presence of a nickel-containing catalyst supported on a carrier at 60-150 deg.C under 50-450 bars pressure. Tungsten oxide or nickel oxide can further be contained in the catalyst, which comprises nickel or nickel oxide in an amount of 5-45 wt.% based on the total weight of the catalyst containing a carrier material and the tungsten oxide in an amount of 0.5-16 wt.% based on the total weight of the catalyst containing the carrier material. The density of the catalyst is 0.60-0.70 kg/L. The catalyst is prepared by respectively settling and adsorbing the nickel, preferably nickel oxide and/or tungsten oxide which are active components of the catalyst from a solution onto an inert carrier material.  Thereby, the prepared catalyst precursor can directly be used for hydrogenation by activation with the hydrogen.

IPC: G01R31/26
Filed: 1990-01-30
Abstract: PURPOSE:To enable influence of noise for a plaiting part to be reduced and achieve an accurate electrical measurement even if a diameter of a semiconductor wafer is smaller than that of a wafer chuck by plating-forming a conductive metal partially on a surface of a chuck top part. CONSTITUTION:A conductive metal 11 is partially plating-formed on a surface of a chuck top part 2 and the plating part 11 of the conductive metal is continuously and electrically connected to a measurement cable 6. With a wafer chuck, an area of the exposed conductive metal plating part 11 is reduced by plating- forming the conductive metal partially on a surface of the chuck top part 2 and a rear surface of a semiconductor wafer can be taken out as an electrode, thus being less affected by noise. Therefore, even if a semiconductor wafer whose diameter is smaller than that of the wafer chuck is mounted, noise may not be carried by a rear surface of the semiconductor wafer, thus achieving an accurate measurement.

Title: Loop transmitter
Inventor: WATANABE AKIRA
IPC: G06F13/00
Filed: 1981-02-18
Abstract: PURPOSE:To prevent a fault of a station from affecting a system, by adding a circuit that given an automatic by-pass to the faulty station. CONSTITUTION:In the normal state, a relay 2 transmits the input signal on a transmission line to a processor 3 and transmits the signal given from the processor 3 to the transmission line. While the relay 2 causes a short circuit to the both ends of the transmission line to give a by-pass to a station. The processor 3 performs all controls related to the transfer of data and at the same time delivers a pulse signal to a timer drive indicating line 4. Receiving the pulse from the line 4, a timer 5 keeps a relay driving line 6 at a certain level for a certain time t2 from a time point when receiving the pulse, keeps the same level if the next pulse arrives within the time t2, and changes the level if the next pulse does not arrive within the time t2. Accordingly the station is by-passed if no pulse is delivered to the line 4 within the time t2 owing to a fault of the processor 3.
