Method of and apparatus for substantially preventing condensation on surfaces of a flow path for lubricant vapor flowing to a magnetic disk to form a lubricant coating on the disk

摘要

Condensation is prevented on surfaces in a flow path for lubricant vapor that applies lubricant coatings to magnetic disks 18 in the flow path. The vapor is derived by heating liquid in a reservoir 24. The flow path includes a vapor chamber between the reservoir and an apertured diffuser 30. The vapor chamber has a first wall extending in the same direction as a straight-line path between the reservoir and the disk and a second wall providing a heat conduction path between the heater and the reservoir. The relative temperatures of the first and second walls is controlled to prevent substantial condensation on surfaces of the flow path.
