  • Patent number: 11045375
    Abstract: A robotic operating table according to one or more embodiments may include: a patient placement table; a robotic arm comprising a plurality of joints, and having a first end supported on a base and a second end supporting the table; and an operation device comprising a preset position registration setting unit that registers an anesthetization position, a surgical operation position, and an imaging position and sets one of the registered anesthetization, surgical operation, and imaging positions as a movement destination of the table, and a move-operation receiving unit that receives, from a user, a move operation to move the table. When the move-operation receiving unit is operated while one of the registered anesthetization, surgical operation, and imaging positions is set as the movement destination of the table, the robotic arm may move the table to the set one of the registered anesthetization, surgical operation, and imaging positions.

  • Patent number: 10813816
    Abstract: A patient placement table moving method may be used with a robotic operating table including a patient placement table, a base buried in or fixed to a floor and an articulated robotic arm including joints and having first and second ends. The first end may be supported on the base to be rotatable about an axis extending in a vertical direction. The second end may support the table. The method may include: horizontally arranging the table by the robotic arm at an imaging position for imaging with a medical imaging apparatus; and translating the table from the imaging position to a surgical operation position by the robotic arm. The surgical operation position may be away from the imaging position by 200 mm or more in a second direction orthogonal to a first direction in a horizontal plane, and the first direction is parallel with a longitudinal direction of the table.

  • Patent number: 10756605
    Abstract: Core slots are provided in an outer circumferential side of a rotor core and extend in an axial direction of a rotor shaft. A rotor conductor is a rod-shaped conductor inserted in each of the slots, and after insertion of the rotor conductor in each slot, a flared portion is formed flaring in a slot-transverse direction, and a propping-apart force occurring between the flared portion and both side wall surfaces of the slot fixes the rotor conductor to the slot. In an inner wall of an outer circumferential side of each slot abutting the flared portion, an unevenness is arranged along the axial direction of the rotor shaft.

  • Patent number: 10752263
    Abstract: A vehicular cooling device includes an opening, a discharge port, an air channel, and a fan. The opening is formed in a surface parallel to a travelling direction of a vehicle. The discharge port is formed in a surface of the housing and connected to the opening via the air channel. The fan is provided inside the air channel. First blockers are spaced apart in the travelling direction in the opening. Each first blocker extends in a direction perpendicular to both the travelling direction and an inflow direction of the outside air, and includes first and second members. The first member is a plate-like member having a main surface intersecting the travelling direction. The first member and the second member are symmetric with respect to a plane perpendicular to the travelling direction, and have a travelling-direction spacing therebetween that increases along the inflow direction of the outside air.

  • Patent number: 10028103
    Abstract: A position management system manages position information of a second apparatus which carries out wireless communications with a first apparatus that is installed indoors. The position management system determines radio field intensity of radio waves of the wireless communications that are received from the first apparatus when movement of the second apparatus is detected, acquires first position information that indicates a position of the second apparatus estimated based on the determined radio field intensity of the radio waves, and stores the acquired first position information associated with time information.

  • Patent number: 9751776
    Abstract: The invention provides a dispersion of zirconium oxide having a content as high as 20% by weight or more, but a low viscosity, and having a high transparency, which has a transmittance of 35% or more at a wave length of 400 nm, a transmittance of 95% or more at a wave length of 800 nm, and a viscosity of 20 mPa·s or less at a temperature of 25° C. Such a dispersion of zirconium oxide can be obtained by reacting a zirconium salt with an alkali in water to obtain a slurry of particles of zirconium oxide; filtering, washing, and repulping the slurry; adding an organic acid to the resulting slurry in an amount of one mole part or more per mole part of the zirconium in the slurry; hydrothermally treating the slurry at a temperature of 170° C. or higher; and washing and concentrating the resulting aqueous dispersion of particles of zirconium oxide.
