  • Publication number: 20220009815
    Abstract: An object is to provide an apparatus and a method for manufacturing a silica glass crucible, both allowing a stable silica powder layer to be formed in a mold in a short period of time. One embodiment of the present invention is an apparatus for manufacturing a silica glass crucible, by forming a silica powder layer on the inside of a rotating mold, which comprises a rotating means for rotating the mold as well as a supply means for feeding a silica powder to the inside of the mold. In this manufacturing apparatus, the supply means has a feeding part for feeding the silica powder in a manner releasing it to fall to a position away from the inner wall surface of the mold on the inside of the mold, as well as a dispersing part for changing, to one toward the inner wall surface side, at the fall position, the direction in which the silica powder fed from the feeding part moves, while also widening the angle at which the silica powder disperses toward the inner wall surface at the fall position.

  • Publication number: 20210379402
    Abstract: A particle beam therapy apparatus has a position and posture setter that moves a movable body, that is at least one of the irradiation nozzle and the treatment table. A movement path of the movable body is determined when adapting the positional posture of the movable body from one condition among a plurality of prescribed conditions to another condition. An evaluation value is obtained for adapting the positional posture of the movable body to each of a plurality of prescribed conditions. This evaluation value is for a case of moving the movable body according to the movement path. A setting order is determined for adapting the positional posture of the movable body to each prescribed condition based on the evaluation value; and the positional posture of the movable body is adapted to each of the plurality of prescribed conditions by moving the movable body according to the determined movement path.
