An electrostatic coating device is provided with a housing, which has a cascade housing section that houses a cascade, and a motor housing section that houses an air motor. A clearance between the cascade and the inner wall of a first housing hole forms a first air flow passage. Furthermore, an annular clearance between the air motor (specifically, an air turbine) and the inner wall of a motor chamber forms a second air flow passage. The first air flow passage and the second air flow passage are communicated with each other via, for instance, a third air flow passage that includes a first communication passage, a circular recessed section, a second communication passage, and a third communication passage.

Present embodiments include a system that includes a welding tool configured to receive a welding wire from a wire feeder, to receive welding power from a power source, and to supply the welding wire to a workpiece during a welding process. The system also includes a mechanical oscillation system configured to mechanically oscillate a structural component toward and away from the workpiece. The structural component is external to the wire feeder and the power source. The system further comprises control circuitry configured to control the welding power based on feedback relating to the welding process.

A dry powder coating apparatus for coating pharmaceutical solid dosage forms includes a housing; a drum coater; a powder coating system; a liquid spray system; a ventilation system; a heating system; a touch screen control panel; and an operation box. The drum coater may have a truncated cone on both sides, in which one side is opened and another side is closed. The drum coater is horizontally placed inside the operation box along its axis and fixed on a rotatable shaft and a motor drives the rotatable shaft and rotates the drum coater about its own axis.
