Inner partitions disposed within a cooling tank have an open space to form arrayed housing parts, and at least one unit of electronic device housed in each of the housing parts. A lifting mechanism includes a tower having a guide and a driving source for raising and lowering an arm, a slide mechanism attached to the cooling tank, and a stopper for restricting the tower's movement so that a range of the tower's motion in a width direction of the cooling tank does not exceed at least a width of the open space. The slide mechanism supports the tower movably with respect to the cooling tank in a horizontal plane located above the open space. The liquid immersion cooling system can safely lift or lower the electronic devices densely housed within the cooling tank without requiring the stage in the periphery of the installation surface of the cooling tank.

An osteotome for sinus lift procedures includes a body interchangeable with various handles. The body includes a shaft that is releasably received into the handle, and a tip portion. The tip portion may be directly utilized for ridge expansion/bone compression, or a succession of tip members may instead be received thereon to provide suitable diameter escalation to create the socket. A conduit in the tip portion interconnects with a conduit in a hydration port and a conduit in a tip member. A hose couples the hydration port to a syringe, to deliver fluid out the tip member to lift the membrane. Graduated syringe markings permit delivery of measured fluid quantities to control the amount of lift. A second hydration port is coupled to a graduated cylinder through a valve, which is opened after lifting is complete, to measure the fluid released. A loss of fluid measured indicates a sinus tear.

A system for safe, efficient lifting of partially fabricated walls during light-frame construction. Such walls are built in a horizontal position and are manually rotated into a vertical position using a lifting apparatus mounted to one or more framing members of the wall. The lifting apparatus allows the wall to be positioned and held at an intermediate resting/safety point for protection of user during the lift. A method of use and kit comprising the lifting apparatus are also disclosed.
