A copper-based alloy includes one base phase selected from the group consisting of &agr; phase, &agr;+&bgr; phase, and &agr;+&bgr;+&ggr; phase, a component having a lower melting point than the base phase, and a component for dispersing the base phase and the low melting component to uniformly disperse the low melting component and improve the copper-based alloy in machinability. A method for producing the copper alloy in the form of a bar or plate includes the steps of compounding raw materials in predetermined ratios thereby obtaining a mixture, fusing the mixture thereby obtaining a melt, continuously casting the melt into a cast billet, or rolling the cast billet thereby obtaining a shaped mass, heat-treating the shaped mass, drawing or rolling the heat-treated shaped mass thereby obtaining a plastic mass, and subjecting the plastic mass to a heat-treatment of air cooling or furnace cooling.

This invention is intended to provide a method for producing a resin composition used for paint which is preferable for improving dispersibility of pigments, thereby improving productivity. The method is characterized in that a plurality of pigments which consist a resin composition used for paint is mixed, the mixed pigments are dispersed at an optimal dispersion mixing ratio with a resin and a solvent, which has been found in advance using a Daniel Flow Point Method (a Flow Point Method), and then other components are added thereto to obtain the predetermined resin composition used for paint. It is particularly preferable for the resin composition used for paint to be an electrodeposition paint composition.

Disclosed is a method of distinguishing an inflammatory pathogen causing acute respiratory infection wherein the pathogen to be distinguished is a pathogen residing in the respiratory tract, which comprises: (a) a step for counting gene copies originating in subject cells in DNA prepared from a specimen containing secretion from the respiratory tract of the subject; (b) a step for counting the gene copies originating in the pathogen in the DNA; (c) a step for calculating the relative value of count of the gene copies originating in the pathogen to the count of the gene copies originating in the subject cells; and (d) a step for distinguishing whether the pathogen is an inflammatory pathogen causing the disease or not based on the distinguishing standard and the relative value.

The present invention provides a membrane structure for a liquid gas storage tank. The structure is characterized in that the bottom wall of the membrane comprises a number of elongated corrugated members arranged in a square-lattice pattern, and each member has a pair of spaced, parallel, longitudinally extending corrugations. Also, the members are assembled by joining one end of each corrugated member to substantially the mid-point of another corrugated member extending normal thereto, and each opening between the corrugated members is closed and made liquid tight by a thin plate.Preferably, each corrugated member is a sheet member of U-shaped cross-section, having a pair of vertical flanges of equal height, located between a pair of sheet members of L-shaped cross-section which are arranged back to back in spaced, parallel relationship, the top edges of respective adjacent vertical flanges of said L-shaped and said U-shaped members being continuously welded together.

A cleaning and releasing device has a hand valve provided on a flow passage of a pressurized liquid in the vicinity of an injection nozzle, a switching valve 5 provided in a proper position on the flow passage of a pressurized gas, flow detecting means provided in a proper position on the flow passage of the pressurized liquid, and a controller for controlling the switching operation of the switching valve based on a result of detection transmitted from the flow detecting means, and controls the switching valve to supply and stop the pressurized gas depending on the presence of a flow of the liquid generated by the switching operation of the hand valve. The supply and stop of a powder and granular material may be controlled based on the result of detection transmitted from the flow detecting means.
摘要:
To provide a method of efficiently searching for a disease sensitivity gene and an apparatus therefor. It is intended to provide: a method of determining a homoeologous region which comprises the polymorphism marker selection step of selecting a polymorphism marker usable as the subject of the homozygote determination, the homozygote determination step of determining whether or not bases constituting a specimen DNA which is a diploid or higher are homozygous, the homozygote haplotype data acquisition step of selecting exclusively polymorphism markers determined as homozygous and acquiring homozygote haplotype data of each specimen, the homozygous region data acquisition step of comparing the above-described homozygote haplotype data of two or more specimens and acquiring common homozygous region data, and the homoeologous region determination step of determining a common homozygous region satisfying definite homoeology requirements as a homoeologous region between the corresponding specimens for each common homozygous region data; and an apparatus and a gene screening method with the use of this method.
摘要:
To provide a method for efficiently searching for a recessive disease gene without needing any pedigree analysis. In a homoeologous region determining method, the following steps are conducted. It is determined whether or not the base constituting a polymorphic marker of a sample DNA of diploid or higher polyploidy is a homojunction. Homojunction region information representing the region of the sample DNA where polymorphic markers determined as continuous homojunctions acquired. If the continuous probability and/or continuous distance of the polymorphic markers contained in the homojunction region information satisfy a predetermined determination condition, the homojunction region is determined as a homoeologous region. A homoeologous region determining device and a gene screening method for identifying a disease susceptibility gene from the determined homoeologous region are also provided.

A water pump is connected to a mixer so as to blast high pressure water at a high speed in the mixer. The air and powder are supplied to the blast flow of the high pressure water through an air supply pipe and a powder supply pipe respectively so that a mixture flow composed of the gas, the droplet-like fluid, and powder is formed. The mixture flow is blasted from a nozzle at a high speed so as to be sprayed onto a surface to be treated. Thus, impact actions held by the powder and the droplet-like fluid as cleansing/scraping media are given to the surface to be treated. Thus, a cleansing/scraping operation is achieved. Then, if the fluid, gas or the like supplied to the mixer is heated, the cleansing/scraping operation can be further accelerated.

A hydraulic braking pressure control system for a vehicle comprises a master cylinder (M) operatively connected to a brake pedal (P), an operation-amount detector (S) for detecting the amount by which the brake pedal is operated, a hydraulic pressure control unit (2.sub.FL etc.) for controlling the hydraulic pressure to be applied to a brake device (B.sub.FL etc.) mounted on a wheel in accordance with an applied quantity of electricity, and a control circuit (3) for controlling the quantity of electricity to be applied to the hydraulic pressure control unit, in accordance with a detection value provided by the operation-amount detector. The system further includes a cut-off valve (30.sub.FL etc.) adapted to be closed in response to depression of the brake pedal, and a reservoir (R.sub.2) connected through the cut-off valve to an oil passage (27) connecting the hydraulic pressure control unit and the brake device. The cut-off valve is opened when the brake pedal is not depressed, and even if a hydraulic pressure is delivered from the hydraulic pressure control unit when there is no braking operation, such hydraulic pressure can be released into the reservoir, ensuring that any such hydraulic pressure is prevented from being applied to the brake device.
