Abstract: An exploration method according to the present disclosure includes: a step (S11) of disposing, in a pipeline (PL) that allows a plurality of manholes (MH) to be interconnected, an electromagnetic wave receiving/transmitting device (1) that transmits an electromagnetic wave and receives a reflected electromagnetic wave that is a reflected wave of the electromagnetic wave; a step (S13) of transmitting the electromagnetic wave; a step (S14) of receiving the reflected electromagnetic wave that is the reflected wave of the electromagnetic wave; and a step (S18) of calculating an intensity distribution of the reflected electromagnetic wave on the basis of an intensity of the reflected electromagnetic wave and a round-trip propagation time from when the electromagnetic wave is transmitted to when the reflected electromagnetic wave is received.

Abstract: This invention relates to antibodies capable of binding to the FK778 substance, to a highly-sensitive immunoassay method, which utilizes an antibody for the FK778 substance, and to a test kit for measuring the concentration of the FK778 substance.

Abstract: The digital camera 1, when a length-direction range expanding button 14 or a breadth-direction range expanding button 15 is operated, changes the length-direction and breadth-direction image pickup effective ranges of a solid state image pickup device 40 using an image pickup effective range setting table 41. Due to this, there can be obtained picked-up images with a length-to-breadth ratio changed without rotating the main body of the digital camera 1. Also, since the length-direction and breadth-direction image pickup effective ranges are adjusted such that the area of the image pickup effective ranges of the solid state image pickup device 40 can provide a substantially constant value, there can be always obtained an image of good quality.

Abstract: A method of and system for cleansing a toilet or urinal are proposed which require less maintenance work and are safer to users than conventional methods using acid substances, and which can prevent the formation of stain on the toilet or urinal effectively and suppress the generation of ammonia sufficiently, thus accomplishing a sufficient countermeasure to the stench. A urinal (A1) is provided with a continuous electrolytic cell (1) having at least a pair of electrodes, a passage formed between the electrodes, and an inlet and an outlet that lead to the passage. Tap water is electrolyzed by the continuous electrolytic cell (1), whereby free chlorine is produced. Then the water containing free chlorine produced is supplied to the urinal (A1), and the water containing free chlorine sterilizes the inside of the urinal, thus preventing urease, an enzyme carried by bacteria, from acting to decompose urea.

Abstract: An electrolyzing apparatus for flowing water containing chlorine ions has an electrolytic cell provided with at least one pair of electrodes, a passage formed between the electrodes, an inlet port and an outlet port communicating the passage, and a power supply for applying voltage across the electrodes.

Abstract: A DC motor brush assembly includes a brush brought into contact with a commutator piece which is connected to the coil of a DC motor, and a brush holder of plastic material for holding the brush against the motor housing. The brush is formed by bending from a bottom shield sheet. The bottom shield sheet is brought into intimate contact with a mold to form a non-molding chamber containing the brush when the brush holder is to be insert-molded. The brush holder is molded integrally over the bottom shield sheet.

Abstract: A commutator assembly includes a plurality of commutator pieces for supplying an electric current from a brush fixed at a motor housing to a coil rotating together with a rotor shaft of a small motor, and a commutator holder of a plastic material fixed to the rotor shaft for supporting the commutator pieces. The commutator pieces are cut out of a commutator piece joint body which has a plurality of commutator pieces radially extending from a single temporary connection and is molded into the commutator holder during molding process.

Abstract: A catalytic composite for deodorizing odorous gases is provided. The composite comprises: ceramic fibers; zeolite supported on the surface of and in the interstices between the ceramic fibers; and gold and an iron oxide both supported mainly on the zeolite; the catalytic composite being so formed as to allow a gas to pass therethrough.

Abstract: For the preparation of a catalytic composite for purifying exhaust gases, first, at least one perov-skite-type compound oxide of the formula RMO.sub.3, where R is La or a combination of La and Ce, and M is Co, Mn or a combination thereof, is supported together with cerium dioxide and alumina sol on a heat resistant carrier made of an inorganic oxide selected from the group consisting of cordierite and mullite, and then iron and palladium are further supported together thereon. As a result, a catalytic composite having a high degree of oxidation activity at low temperatures and also having excellent heat resistance can be obtained.

Abstract: The present invention is an exhaust smoke purifier apparatus which contains a reservoir part consisting of an adsorbent and a purifier part. The purifier part includes a purifying agent. The present invention has a regeneration function and oil smoke and the like generated in cooking is drafted into the purifier apparatus by a greater air blow rate to temporarily hold it in the reservoir part. After cooking, the oil smoke and the like is introduced from the reservoir part into the purifier part at a smaller air blow rate and is thereby purified. The exhaust smoke purifier apparatus requires minimal manual treatment for captured oil smoke and the like, and is very clean. The apparatus can effectively purify with a very small amount of purifying agent. The apparatus can also be made small.

Abstract: A catalytic composite for purifying exhaust gases is disclosed which comprises ceramic fibers, oxidation catalysts supported on the surface of the ceramic fibers and in the interstices between the ceramic fibers, and inorganic binders for binding the oxidation catalysts to the ceramic fibers, the catalytic composite being provided with vent holes for the passage of exhaust gases. Also disclosed is a method for preparing the catalytic composite.

Abstract: An oxidation catalyst of the perovskite-type compound oxide which comprises, as A site, a mixture of rare earth elements from ores, part of which is replaced by at least one element selected from alkali metals, alkaline earth metals and rare earth elements other than the ore-originating elements, and a transition metal as B site. The surface atomic ratio of the mixed rare earth elements and the transition metal is in the range of 1.0:1.0 to 1.1.:1.0. A method for preparing the compound oxide is also described.
