Abstract: In an electrochemical gas sensor (10), a first sensing element (21) is stored in a first storage portion (31). A moisture permeable film (24) is disposed in a first introduction inlet (31A) of the first storage portion (31). The moisture permeable film (24) substantially prevents a to-be-detected gas from permeating therethrough. A second sensing element (22) is disposed in a space into which water vapor and the to-be-detected gas contained in a target gas flow. In such a configuration, the electrochemical gas sensor (10) is capable of detecting a to-be-detected gas having a concentration of 0 or more and 1 ppm or less.

Abstract: An ozone generator (100) includes: a flow path (1) through which gas flows from an inlet (5) to an outlet (6); an ozone generation unit (3) disposed in the flow path (1); and an ozone sensor (4) disposed in the flow path (1) and upstream of the ozone generation unit (3). The flow path (1) has an upstream-side flow path (130) that forms a gas passing space (AR) located upstream of the ozone generation unit (3) and through which the gas flows from one side to another side in a predetermined direction. The inlet (5) is disposed closer to an outer circumferential portion (131) of the upstream-side flow path (130) than the ozone sensor (4).

Abstract: The present invention provides a method of manufacturing a semi-hard magnetic material comprising, sequentially: preparing a raw material consisting essentially of 10.0 to 25.0% of Ni, 2.0 to 6.0% of Mo and the balance being Fe and inevitable impurities, in mass %; heat-treating or hot-working the raw material so that it has not less than 90% of martensitic structure; cold-working the material at a reduction of area of not less than 50% so that it has an extended structure including not less than 95% of a martensitic structure; and heat-treating the material in a range of 400 to 570° C. so as to generate more than 0% but less than 30.0% of reverse-transformed austenitic structure. The semi-hard magnetic material manufactured using this method can possess a coercive force of 1000 to 5600 A/m.

Abstract: To provide infusion therapy that can effectively transluminally deliver drugs or the like to a target spot without invading areas other than a diseased area. The infusion therapy is for administering a drug, cells or the like, or inserting a treatment instrument into the target diseased area. A blood vessel area including a bifurcated blood vessel connecting to the diseased area is occluded at the distal and the proximal region thereof to form an occluded area, and the drugs or the like are pumped and supplied to the occluded area, which causes the drugs or the like to flow retrogressively and retentively in the bifurcated blood vessel connecting in the occluded area, and be infused and administered to the diseased area.

Abstract: An Fe—Co—B alloy target, in which the largest inscribed circle depictable in regions containing no boride phases in its cross-sectional microstructure has a diameter of 30 ?m or less. Its composition is represented by (FeXCo100?X)100?YBY (by atomic percentage), wherein 5?X?95, and 5?Y?30.

Abstract: A balloon catheter capable of adjusting a position to inflate a balloon in the axial direction of a catheter is provided.

Abstract: To provide a catheter and a method for infusion therapy that can effectively transluminally deliver drugs or the like to a target spot without invading areas other than a diseased area. The catheter is a balloon catheter for insertion into a blood vessel in which four lumens extending along an axis are formed in one catheter body, and two balloons are arranged axially in parallel. The plurality of lumens include: an infusion lumen that communicates with an infusion hole between the two balloons; balloon lumens that communicate with insides of the two balloons to expand the balloons; and a guide lumen that also serves as a bypass lumen that communicates with an outside of the catheter body in each position distal and proximal, which is outside of the two balloons with respect to a tip a of the catheter body, and bypasses an occluded area formed by the two balloons to allow blood flow.

Abstract: The rotary machine is composed of the rotor having magnetic poles and the stator having the stator yoke portion constituting the iron core tooth portion wound by the stator winding and the flux flow path of the magnetic poles. The rotor is composed of a metallic material having ferromagnetic parts and non-magnetic parts as a member and has a magnetic barrier area composed of the slit portion for blocking the bypath magnetic path in the periphery of the rotor and the non-magnetic parts. The rotary machine that produced torque can be increased sufficiently and the mechanical strength during high-speed running is improved and an electrical vehicle using it.
