Patent JP-H0350911-A (JP)
Title: Prediction device
Inventor: IWADARE MASAHIRO
IPC: H03H17/02
Filed: 1989-07-19
Abstract: PURPOSE:To execute the prediction with high accuracy by finding out a part whose waveform of a difference of input signals is similar from a past difference signal with the correlation coefficient so as to obtain a prediction value. CONSTITUTION:An input signal is preserved with a delay device 2 by a time being an integral number of multiple of the sampling interval. A computing element 3 calculates a difference X of the input signal and a storage circuit 4 preserves L set of past signals X. Moreover, the signal X is inputted to an oversampling circuit 5 and its sampling frequency is multiplied by an integral number of multiple. A storage circuit 6 stores 2k sets of past outputs XL of the circuit 5. A calculation section 7 obtains the evaluation of the correlation and the average amplitude ratio of the signals X and XL, a detection circuit 8 obtains a time M in which the absolute value of the correlation coefficient P is maximum among (2k-L+1) sets of the correlation coefficients P and outputs the time M, a coefficient P(M), and an average amplitude ratio AC(M). A multiplier P obtains the product among the signal XL(M+1), the ratio AC(M) and a code of the coefficient P(M) and the sum of a prediction value of a difference signal at the succeeding sampling time to the input signal of the succeeding sample time is obtained from the adder 10.

IPC: B60T17/04
Filed: 1994-08-05
Abstract: PURPOSE:To shorten the length of pipelines, facilitate piping work and allow a cross member to be set high by disposing the pipelines in the form of plural rows and plural stages belows the cross member, along a side member. CONSTITUTION:A body 1 is constituted of a floor 2, lateral side members 3 serving as longitudinal beams disposed at the lower face, and a cross member 4 laid across the side members 3. At least three pipelines 7 are linearly passed below the floor 2 and disposed in the form of plural rows and plural stages below the cross member 4, along the side member 3. Plural pipelines 7 are gripped by clamps 10 disposed at constant spaces apart, covered with a protector 20 from the outside of the clamps 10 and fitted to the side member 3 by stays 30 disposed outside of the stays 30 at the same spaces as the clamp 10. The total height of the pipelines is thereby lowered, so that the height of the cross member 4 can be set high. Pipelines can be thereby laid without making a detour around the cross member 4, so that the length of the pipelines is shortened, and piping work is facilitated.

Title: Multilayer-type radio wave absorber and radio wave anechoic chamber composed of said wave absorber
Inventor: ISHINO TAKESHI
IPC: E04B1/92
Filed: 1988-07-26
Abstract: PURPOSE:To expand a frequency band, to reduce a return loss, to stabilize an electromagnetic field distribution and to improve the reliability of data by constituting an anechoic chamber in such a way that a multilayer-type radio wave absorber which has a ferrite of large permeability and a dielectric arranged on the rear of the ferrite is pasted or applied to the whole wall face concerned. CONSTITUTION:A concrete 2 of a dielectric and a metal 3 are arranged on the rear of a nickel and zinc-based ferrite whose permeability is large; a multilayer-type radio wave absorber is formed. As a wave absorption characteristic by changing a thickness of the ferrite at a definite thickness of the concrete in this wave absorber, a best characteristic is obtained when the thickness of the ferrite is a prescribed value; there is a tendency that a high-frequency characteristic becomes remarkably better and that a frequency width becomes wider and better. This tendency is not changed largely if the permeability is changed. Accordingly, when the multilayer-type radio wave absorber is pasted or applied to the ceiling, wall and floor of the anechoic chamber, an electromagnetic field distribution becomes very stable and the reliability of data is improved.

Abstract: PROBLEM TO BE SOLVED: To prevent pitting corrosion of a metal used in a water system by bringing a water containing corrosive ions into contact with an anion exchange resin to remove the corrosive ions and then adding a small amt. of a phosphorus compd. into the water system. SOLUTION: A water containing corrosive ions such as Cl<-> and SO4 <-2> is brought into contact with an anion exchange resin, preferably an anion exchange resin carrying anticorrosive anions such as OH<-> and HCO3 <-> , so as to exchange anions to remove the corrosive ions. Then a phosphorus compd. is added by >=0.5 mg/L calculated as PO4 to the water system from which the corrosive ions are removed. Thereby, the use amt. of the phosphorus compd. can be decreased by about <=1/10 compared to a process without the treatment by an anion exchange resin. As for the phosphorus compd., inorg. phosphoric acid, tripolyphophoric acid, sodium hexametaphosphate, etc., can be used. If necessary, an acrylic acid copolymer and the like is added to suppress the production of phosphate scale.

Abstract: PURPOSE:To enable automating of a weld detection even if a thickness of a material to be measured changes, by a method wherein a signal obtained from a transmitting and receiving coil is properly used as a thickness measuring signal and a weld detecting signal. CONSTITUTION:A receiving signal from a transmitting and receiving coil 4, mounted to a surface positioned facing and opposite to a metal material 1 of a magnet and applying a static magnetic field to the metal material 1, is transferred to a comparator 12 amplified by an amplifier 8 to compare it with a set value M. The output of the comparator 12 is applied to a gate circuit 16 via a gate control circuit 13 and an FF 14 to cause a clock generated by a clock generating circuit 15 to pass during only a period of time corresponding to the thickness of the metal material 1. Its clock train is counted by a counter 17, a resultant data is fed to a thickness measuring circuit 18, and a thickness information is transferred to a time control circuit 11 to control a gate circuit 9 and a comparator 10. A signal, passing through a gate circuit 19 controlled corresponding to the thickness of the metal material 1, is compared with a set value L by the comparator 10, and this catches a return loss at a weld to drive a relay circuit.

Title: Material for immunological detection and immunological detection method
Inventor: NISHIKAWA IKUKO
IPC: G01N33/53
Filed: 1989-07-18
Abstract: PURPOSE:To measure the existence quantity of a material to be detected by conjugating a fluorescence material with the material to be detected or the analogous material thereof and intensifying the fluorescence with the fluorescence emitted by an antibody to the material to be detected when the fluorescence material conjugates with the antibody as exciting light. CONSTITUTION:The material formed by conjugating the fluorescent material with the material to be detected or the analogous material thereof is previously conjugated with the antibody soln. to the material to be detected. The intensity of the fluorescence changes with the competitive reaction between the material mixture and the material to be detected when the material to be detected is added to this soln. mixture. The existence quantity of the material to be detected is measured by utilizing this change. The reaction progresses fully in the homogeneous system (liquid phase) in this way and further, an enzyme reaction is not used and, therefore, the time for detection is drastically shortened.
