Abstract: Methods for magnetically enhanced physical vapor deposition are disclosed. The methods include providing a magnetically enhanced vapor deposition device defining a vapor deposition chamber, having a magnetic field source proximate a magnetron target that is positioned within the vapor deposition chamber and coupled to a power source, and having a substrate holder positioned within the vapor deposition chamber, placing a substrate in the substrate holder, activating the magnetic field source to provide a magnetic field that controls a charged particle flux within the physical vapor deposition chamber, and activating the power source thereby depositing a few-layer film of the material comprising the magnetron target onto the substrate. The few-layer film may be a transition metal dichalcogenide, such as MoS2.

Abstract: The present invention discloses a safety trigger mechanism and functional frame for motion furniture for driving a drive mechanism of motion furniture. The safety trigger mechanism includes a mounting board, and a pull wire, a fork and a first restoring spring connected in turn. The fork is mounted turnably about a first rivet on the mounting board by the first rivet, and a bent hook is disposed on one end of the fork and interlocked with a driving arm of the drive mechanism. The safety trigger mechanism further includes a safety hook with a notch, which is mounted turnably about a second rivet on the mounting board by the second rivet. One side edge of the safety hook abuts against the bent hook of the fork, and the driving arm has an arresting pin disposed thereon. The initial position of the arresting pin is in the notch of the safety hook, and the arresting pin is detached from the notch of the safety hook when the safety hook turns clockwise.
