Title: Method for eliminating blue tide
Inventor: MATSUMOTO SATOSHI
IPC: C02F7/00
Filed: 1989-03-03
Abstract: PURPOSE:To obtain the method for eliminating blue tide which can eliminate the blue tide by efficiently dissolving oxygen into sea water. CONSTITUTION:The blue tide is eliminated by sucking the sea water, packing compressed air into this sea water to form the compressed air-packed pressurizing water and ejecting the compressed air-packed pressurizing water into the sea water.

Patent JP-S5017503-A (JP)
IPC: G10L25/15
Filed: 1974-05-08
Abstract: The use of electronically tunable filters permit an efficient extraction of characteristic speech features, such as pitch frequency and the position of spectral peaks, called formants, that are present in vowels and voiced consonants. A pair of electronically tunable active filters each controlled for CF and Q, are utilized to "lock in" on a particular formant and to follow its inflections. The control voltage supplied to the active filters directly corresponds to the formant position and gives an inexpensive and simple technique for the characterization of voiced phonemes.

Title: Nondestructive simple discriminating method of low-chromium steel
Inventor: YAMAMOTO MASATO
IPC: G01N31/22
Filed: 1980-04-17
Abstract: PURPOSE:To ensure a simple and quantitative discrimination for chromium content in the low-chromium steel, by carrying out an electrolysis with use of a strong oxidizing agent such as ammonium persulfate, HNO3, H2O2 and the like. CONSTITUTION:The thick filter paper 2a impregnated with the electrolyte that dissolves the object to be tested 1 is set at the side of cathode plate 4; while the thin filter paper 2b impregnated previously with ammonium persulfate and then dried is set at the side of anode of the object to be tested 1. These two papers are stacked together in opposition to each other. Then a DC power source 3 is applied between the anode 1 and the cathode plate 4 to carry out an electrolysis. Thus the oxide ion of chromium eluted from the anode 1 is accumulated on the paper 2b. This ion is made to emit light by a light emitting reagent composed of the alcohol solution of diphenlcarbazide. This coloring is compared with the standard colorimetric table prepared previously to discriminate the chromium content. In such way, the chromium content can be discriminated in a simple and quantitative way for the low-chromium steel (<=1%).

Title: Vics beacon am modulation abnormality detection system
Inventor: HIYAMA YOSHIAKI
IPC: H04B7/26
Filed: 1993-03-11
Abstract: PURPOSE:To always hold a VICS beacon in a satisfactory operating state by detecting the clock signals of in phase and opposite phase transmitters, and outputting an abnormality signal when one or both clock signals are not detected. CONSTITUTION:The in-phase and opposite phase clock signals are inputted to the inverted input terminal and non-inverted input terminal of a first operating amplifier 1, and the output of the first operating amplifier 1 is the difference of the two signals whose phases deviate by 180 deg., that is, a value obtained by adding the absolute values. When a fault occurs at the transmitters, and one of the AM modulations is not operated, the clock signal of one system is not generated, and the output waveform of the operating amplifier 1 becomes the waveform of the relatively low value inputted to one terminal. Moreover, when the both clock signals are not generated due to the fault of the transmitters, the output of the operating amplifier 1 is turned to 0. When abnormality occurs at the transmitters, and the AM modulation of the two systems is not normally operated, an abnormality detection signal is obtained from an output terminal 7 of the circuit.
