  • Patent number: 10826263
    Abstract: A laser medium unit includes: a plate-shaped laser gain medium which includes a first surface and a second surface opposite to the first surface and generates emission light by the irradiation of excitation light from the first surface; a reflection member that is provided on the second surface so as to reflect the excitation light and the emission light; and a cooling member that cools the laser gain medium. The laser gain medium includes an irradiation area which is irradiated with the excitation light and an outer area which is located outside the irradiation area when viewed from a thickness direction intersecting the first surface and the second surface. The cooling member is thermally connected to the second surface through the reflection member so that a cooling area of the laser gain medium is formed on the second surface.

  • Patent number: 10508912
    Abstract: A device configured to apprehend a road surface shape by using data measured by a measuring device appropriately apprehends a road surface shape. A road surface shape measuring device is provided with a road surface information acquiring unit and a road surface shape determining unit. The road surface information acquiring unit acquires road surface information about each of multiple points on a road surface, the road surface information including: a road surface position which is the position, of the road surface, on a reference plane divided into a plurality of sectioned regions; and a road surface height which is the height of the road surface at the road surface position. The road surface shape determining unit estimates respective surface shapes of the sectioned regions by using the road surface information included in the corresponding sectioned regions, and thereby determines a partial shape or the entire shape of the road surface.

  • Patent number: 8603111
    Abstract: A ligating apparatus including a thread receiving portion movably disposed at a distal end of an inserting part body. An outer circumference of the thread receiving portion forms the loop holding portion around which a knot forming loop formed from a ligature is disposed. When a first end of the ligature is pulled into the thread receiving portion, the knot forming loop is pushed out of the loop holding portion by a delivery portion of the knot pusher. The knot forming loop is further pushed by the delivery portion along the ligature toward tissue and ligated. Such ligating apparatus is capable of reducing a load on the tissue to be ligated during a ligating operation.
