  • Patent number: 11746585
    Abstract: A first end portion of a connecting part of a connecting member reaches a locked member arranged such that the thickness direction of one of two construction materials is an axial direction N, and a second end portion of the connecting part reaches the other one of the two construction materials. The second end portion is formed to have a torsion angle ? as an inclination angle to the axial direction N. When the second end portion is coupled with the other construction material by a coupling fitting, the torsion angle ? reduces or disappears, a torsion angle to the axial direction N is generated in the first end portion, the first end portion locks on the locked member, and the connecting member connects the two construction materials.

  • Patent number: 11450436
    Abstract: Samples each including a feature amount and a label indicating one of a first value and a second value are classified into three or more clusters according to their feature amounts. Some of the clusters are combined to form a combined cluster on the basis of information on the number of samples with labels of the first value. The accuracy level of each sample with respect to the first value or the second value is calculated on the basis of the result of classifying into the combined cluster and the remaining clusters. Then, machine learning is performed using samples whose accuracy levels do not meet a prescribed condition more preferentially than samples whose accuracy levels meet the prescribed condition.

  • Publication number: 20220220793
    Abstract: A connecting fitting (20A) for connecting two construction materials includes a first connecting member (21) and a second connecting member (22) for connecting the construction materials, and a parallelizing means (45) having a parallelizing function of aligning the connecting members (21, 22) in a first direction and making them parallel or almost parallel to each other. The first direction is a direction perpendicular to both the direction (M) of an interval between the two construction materials and the thickness direction of one construction material. The parallelizing function of the parallelizing means (45) disappears due to a load caused to act on at least one of the connecting members (21, 22). The inclination angles of the connecting members (21, 22) with respect to the direction (M) of the interval become inclination angles (?1, ?2) opposite to each other due to the disappearance of the parallelizing function.

  • Patent number: 7741616
    Abstract: A liquid in which fine solid Sn particles are dispersed in a resin is accommodated inside the heated tank 4. The resin pressurized by a pressurizing pump is conducted to a nozzle 1, so that a liquid-form resin is caused to jet from the tip end of the nozzle 1 that is disposed inside a vacuum chamber 7. The liquid-form resin which is caused to jet from the nozzle 1 assumes a spherical shape as a result of surface tension, and is solidified by being cooled in a vacuum, so that a solid-form target 2 is formed. A laser introduction window 10 used for the introduction of laser light is formed in the vacuum chamber 7, and laser light generated from a laser light source 8 disposed on the outside of the vacuum chamber 7 is focused by a lens 9 and conducted into the vacuum chamber 7, so that the target is converted into a plasma, thus generating EUV light.

  • Patent number: 7706058
    Abstract: A multilayer mirror aims to reduce incidence angle dependence of reflectivity. A substrate is made of low thermal polished expansion glass with 0.2 nm RMS or less roughness of the surface. On the surface thereof formed is a Ru/Si multilayer having a wide full-width half maximum of peak reflectivity, and on the Ru/Si multilayer formed is a Mo/Si multilayer having a high peak reflectivity value. This enables higher reflectivity than when Ru/Si alone provided and a reflectivity peak having a wider full-width half maximum than when the Mo/Si multilayer alone provided. Since Ru absorbs EUV ray more than Mo does, higher reflectivity is obtainable than that of a structure having the Ru/Si multilayer formed on the Mo/Si multilayer. The multilayer with a wide full-width half maximum has small incidence angle dependence of reflectivity in spectral reflectivity, thereby achieving high imaging performance in projection optical system.
