Title: Water-repellent ceramic coating film and its production
Inventor: NAKAGAWA TORU
IPC: C23C18/12
Filed: 1997-02-06
Abstract: PROBLEM TO BE SOLVED: To form a coating film which almost permanently maintains the initial water repellency without maintenance by incorporating molecules having fluoroalkyl groups and titanium oxide into an oxide film of at least one of Si, Al, Ti, Zr, Sn and W. SOLUTION: A coating soln. containing a hydrolysate of fluoroalkyl methoxysilane or fluoroalkyl ethoxysilane, titanium oxide particles, and at least one hydrolysate of alkoxide compd. of Si, Al, Ti, Zr, Sn or W is applied on a base body and calcined. The obtd. water-repellent ceramic coating film contains molecules 3 having fluoroalkyl groups and titanium oxide 4. Some of titanium oxide particles 4 are exposed on the surface of the water-repellent ceramic coating film and decompose org. molecules depositing on the surface of the photocatalytic effect. Thereby, since the surface by the film is not coated with org. molecules, the film maintains its water repellency.

Title: Treatment of fluorine-containing discharge water
Inventor: YO SATOSHI
IPC: C02F1/58
Filed: 1998-02-04
Abstract: PROBLEM TO BE SOLVED: To surely detect break through of particulate calcium carbonate- packed towers. SOLUTION: The packed towers 18, 20, 22 packed with the particulate calcium carbonate are connected in series. PH and a calcium ion concentration of the treated water of the second stage of a packed tower (e.g. 20) next to the first stage of a packed tower (e.g. 18) allowed raw water to floor in, are detected with a pH monitor 32 and a Ca monitor 34. A control device 44 detects break through of the packed tower 20 at the time of causing both lowering of the pH and lowering of the calcium ion concentration. Thus the packing in the packed tower 20 reached the break through is replaced.

Title: Inverting circuit for black and white level of video signal
Inventor: ISOGAWA TOSHIAKI
IPC: H04N5/14
Filed: 1983-02-16
Abstract: PURPOSE:To eliminate the need for a clamping circuit which coincies the pedestal level of an output video signal in negative mode to that in positive mode, by spcifying the pedestal levels of both output video signals to the same level. CONSTITUTION:A video signl SV is inputted to a terminal 21 and a negative/ positive switching signal SNP from a terminal 30 is at a low, level, so a transistor (TR) Q31 is off and a TRQ32 is on to turn on TRs Q27 and Q28, obtaining a signal with the same polarity with the signal SV at an output terminal 28. At this time, TRs Q45 and Q46 also conduct, and the pedestal level PDL of the video signal is as shown by an expression, where 2I26 and 2I36 are current values of current source 25 and 36, VCC is a source voltage, and R26 is the resistance value of a resistance 26. The signal SNP is at a high level in negative mode, so the TRQ31 turns on and TRs Q29 and Q30 turn on, so that the output signal at a terminal 26 has the polarity opposite to that of the output signal. At this time, the difference between the signal SNP and the base potential E6 of the TRQ42 is equal to the PDL of the output signal, so the PDL of the output video signal is as shown by the expression.

Inventor: ARUFURETSUDO SHII GURIINKUUISU
IPC: G01N33/538
Filed: 1987-02-06
Abstract: A heterogeneous specific binding assay method for determining the amount of a suspected analyte in an aqueous test medium wherein a reaction mixture is formed by combining the test medium with assay reagents including a labeled reagent, an immobilizable component, and a binding substance which causes the immobilizable component to precipitate. Free and bound species of the labeled reagent are formed as a function of the amount of the analyte in the test medium. One of the free and bound species of the labeled reagent is immobilized by binding of the immobilizable component with the binding substance. The immobilized labeled reagent is separated from labeled reagent which has not been immobilized, and the amount of label in the labeled reagent in one of the separate fractions is determined and related to the amount of analyte in the test medium. The improvement provided is the use of an immobilizable component comprising a water dispersible, aggregatable reagent comprising a binding partner for the one of the free and bound species to be immobilized and a first binding substance which upon binding of a second binding substance forms a precipitated complex of the aggregatable reagent.
