  • Patent number: 10809274
    Abstract: There are prepared a first container which stores a liquid containing a cellular aggregate, a second container which receives a cellular aggregate, and a third container which stores a preliminary treatment solution, and a cylinder tip. The cylinder tip is formed with a syringe including a tubular passage having a front end opening which sucks the cellular aggregate, and a plunger which reciprocates in a tubular passage. Before sucking the cellular aggregate from the first container and discharging the same to the third container, the preliminary treatment solution is retained in a space between the tubular passage and the plunger by dipping the front end opening of the cylinder tip into the preliminary treatment solution in the third container and causing the plunger to reciprocate.

  • Patent number: 10378647
    Abstract: A shift lever device includes: a lever main-body; a hollow knob provided at a lever main-body distal end portion; a shift-button rotatably mounted to the knob; and a rod that is inserted-through interior of the lever main-body. The shift-button has a contact surface extending in direction of being away from a rotating-shaft of the shift-button, and that, when the shift-button rotates with respect to the knob, contacts an upper end portion of the rod and lowers the rod. Given that direction orthogonal to axial-direction of the rotating-shaft on plane orthogonal to axis of the rod is reference-direction, and that, among tangent-lines at contact points of the contact surface and the rod, tangent-line on plane orthogonal to the rotating-shaft is reference tangent-line, rotation range of the shift-button is set such that, partway through rotation, the reference tangent-line passes position at which the reference tangent-line becomes parallel to the reference-direction.
