  • Publication number: 20230330434
    Abstract: By using a marker excellent in durability in a multi-leaf collimator, positions of the markers are accurately detected, and positions of the leaves are accurately controlled. The markers are plates containing a phosphor, and surfaces of the plates are fixed to surfaces of the leaves such that end surfaces of the plates are located on predetermined end surfaces of the leaves. An image of the end surfaces of the plates is captured by a camera, and positions of the end surfaces are recognized by image processing.

  • Publication number: 20230041443
    Abstract: A new implant for bone fracture treatment that can easily and securely fix bone fragments is provided. An implant 2 for bone fracture treatment that covers bone fragments gathered at a site to be treated for a bone fracture in a living body and reduces and fixes the site invasively includes a metal knit portion 10 formed by knitting a metal string 11 constituted by one or a plurality of biocompatible metal string elements 12 into a cylindrical shape by circular knitting. The implant 2 further includes a resin knit portion 30 formed by knitting a resin string 31 constituted by one or a plurality of biocompatible resin string elements into a cylindrical shape by circular knitting. The metal knit portion 10 and the resin knit portion 30 are knitted to be continuous in an axial direction.

  • Patent number: 11551838
    Abstract: A grain-oriented electrical steel sheet according to the present invention has a steel sheet surface provided with grooves. An average protrusion height of the surface protrusion extending along a longitudinal direction of the groove is more than 5 ?m and not more than 10 ?m. When the surface protrusion is viewed in a cross section including the longitudinal direction of the groove and a normal direction of the steel sheet surface, the surface protrusion includes specific portions each having a height of 50% or more with respect to a height of each peak point appearing on a profile line of the surface protrusion. In the longitudinal direction of the groove, the total length of the specific portions is a length of 30% or more with respect to an overall length of the surface protrusion.
