Title: Iron/manganese multiple phosphate
Inventor: TAKASUKA YUTAKA
IPC: A61K8/00
Filed: 1998-01-21
Abstract: PROBLEM TO BE SOLVED: To obtain an excellent ultraviolet absorber having no thickness feeling even if being blended in a composition by using a multiple phosphate of Fe, Mn and one or more kinds of metals selected from Cr, Ce, Mg, Al, Ti, Zn, K, Ca and Na. SOLUTION: This multiple phosphate is water-insoluble or hardly soluble, and exhibits ultraviolet absorption action even in a water based carrier. As the concrete multiple phosphate, (Fe, Mn, Cr)PO4 , (Fe, Mn, Ce)PO4 and the like are exemplified. Though the multiple phosphate is produced by an ordinal phosphate producing method, a closed system liquid phase method is particularly preferable. Concretely the method for mixing an aq. solution of a Fe and a Mn water soluble salt and a solution of water soluble salts of one or more kinds of metals selected from Cr, Ce, Mg, Al, Ti, Zn and K with a solution of a water soluble phosphate such as sodium phosphate in an autoclave and drying a precipitate produced by the reaction is exemplified.

Title: Two-stage electrolytic coloring method of aluminum and aluminum alloy
Inventor: UNEZAKI AKIHIRO
IPC: C25D11/12
Filed: 1979-03-01
Abstract: PURPOSE: To form the colored film of superior corrosion resistance and abrasion resistance by electrolyzing the Al or Al alloy having been formed with a porous oxide film through anodic oxidation in an aqueous sulfuric acid solution containing heavy metal salts, with the same as anode, under the DC constant voltage below the foregoing electrolysis voltage then intermitting DC constant voltage electrolysis with the same as cathode.  
     CONSTITUTION: Al or Al alloy is subjected to primary electrolysis treatment, i.e., anodic oxidation treatment, in an aqueous solution of 80W300g/l sulfuric acid (primary electrolyte) to let the porous oxide film of the target thickness be formed. Next, this treated matter being held intact without rinsing is subjected as anode to the DC constant voltage electrolysis in an aqueous solution of 30W200g/l sulfuric acid (secondary electrolytic coloring solution) containing heavy metal salts (e.g., stannous sulfate) being coloring metal salts at the DC constant voltage lower by 2W 5V than the primary electrolysis voltage, i.e., of 8W15V, whereby the activation of the film is achieved. Thence, with this treated matter as cathode, it is intermittently subjected to the DC constant voltage electrolysis approximately equal to the primary electrolysis (12W25V), whereby the even dark color film is formed.

Title: Pulse generation circuit
Inventor: KOUNO MITSUMO
IPC: H04N5/04
Filed: 1990-02-02
Abstract: PURPOSE:To output stable various pulses without being influenced by the noise of a composite synchronizing signal by providing a pulse generation circuit to mask the pulse other than the sink part of the pulse from a first counter, and output the pulse synchronizing with the leading edge of the sink part, and a second counter to generate a masking pulse for determining a masking period. CONSTITUTION:Output a2 becomes 'L' simultaneously with the down count of a first time. The output of the output terminal 11a of the counter 11 rises up Ts later than the leading edge of the sink. Thus, a small pulse is outputted from the output terminal Q of a D flip flop 1 Ts later than the leading edge of the sink. Accordingly, the counter 14 is reset Ts later than the leading edge of the sink. It is assumed that the noise is mixed in synchronizing input a1. If the width of a noise pulse is narrow, and is narrower than Ts, since the counter 14 shifts from up-count to down-count before the output from the counter 11 becomes 'H', this noise is neglected. Therefore, since this noise has no effect upon BG pulse (d) and the output e1 of an RS flip flop, it never exerts influence upon an AFC reference pulse e2.

IPC: H04N5/14
Filed: 1998-02-05
Abstract: PROBLEM TO BE SOLVED: To automatically optimize the phase of sampling in the A/D conversion of a video signal through simple constitution. SOLUTION: When a clock D is generated from the synchronizing signal of the display output of a personal computer, etc., and the video signal A of the display output is sampled by an A/D converter 2 by using the generated clock D to derive a digital video signal F, the delay time of the generated clock D for sampling the video signal A of the above display output is automatically adjusted to optimize the video signal A of the display output and the phase of the generated clock D.

Patent JP-S55116216-A (JP)
Title: Inclination gauge
Inventor: ITOU NOBORU
IPC: G01C9/08
Filed: 1979-03-01
Abstract: PURPOSE: To check the influence of horizontal swings by a method wherein the inclined angle of an object is detected by the uses of an accelerometer as a weight of a pendulum and the acceleration of gravity while the period of the pendulum is made longer than that of horizontal swings of the object.  
     CONSTITUTION: When an object 1 makes horizontal movement, its position X is X=X 0 sinωt, the acceleration x, x=-ω 2 X 0 sinωt, thus acceleration of an accelerometer 2 as a pendulum weight becomes a=(-ω 2 g/l)(X 0 sinωt)(g/l-ω 2 ). Therefore, the ratio a/x is a/x=(g/l)/(g/l-ω 2 ). This equation indicates that if the period ω of the pendulum is greater than the number of circular swings (g/l) 1/2  sufficiently, the a/x approaches zero. As a result, it is possible to measure the inclination of the object without influence of its horizontal swings if the period of the pendulum is made longer than that of the horizontal swings.

Title: Frequency comparator
Inventor: MIZUGUCHI HIROSHI
IPC: H03K5/26
Filed: 1981-02-20
Abstract: PURPOSE:To obtain stable operation by providing a frequency comparator, which uses a bistable circuit and is suitable for LSI-implementation, with a flip-flop which inverts an output terminal level when an insignificant pulse which does not inverts the output of the bistable circuit is inputted. CONSTITUTION:A reference pulse B is inputted to a terminal B. When a pulse A is not inputted to a terminal A, a flip-flop 14 is reset by the pulse B. A D flip- flop 18 is triggered at every leading edge of the pulse B, but never changes because a delay terminal D2 is at an ''L''. When the pulse A is inputted, the flip- flop 14 is set at its leading edge. At the leading edge of the pulse B, the D flip- flop 18 is triggered and its output is inverted. At the trailing edge of the pulse A, the flip-flop 14 is inverted. Even if the leading edge of the pulse A is inputted before the arrival of the pulse B, the couput of a D flip-flop 15 never changes.

Filed: 1978-03-08
Abstract: PURPOSE: To issue a preventive alarm without malfunction due to harmless gas, by presuming onset of short-circuit trouble due to electric deposition of silver plated parts in an electric appliance caused by pollutants such as sulfide gas and humidity in the air by prior deposition of silver of the own detecting part.  
     CONSTITUTION: A detecting part 4, a buzzer 5, and a relay 6 are connected to the direct-current power source of a rectifier 3. The detecting part 4 is disposed closely by printing silver plated electrodes 9, 10 on an insulation plate 8. The opposing distance l d  between the electrodes 9 and 10 is set to about 1/2 to 1/10 of the  distance l g  between parts in an ordinary electric appliance. The detecting part is placed in the vicinity of the electric appliance. If gas is present in the atmosphere and humidity is large, since direct-current voltage is applied to the detecting part 4 through the relay 6, the electrode 10, namely, the silver on the magnative electrode, is deposited to stretch like branches of a tree until finally reaching the electrode 9, resulting in short circuit of the electrodes. Accordingly, a current flows in the buzzer 5, warning air pollution. At the same time, the relay 6 is actuated to close the contact 7 to self-hold the relay, thereby stabilizing the continuous alarming of the buzzer 5.
