A new equipment is developed to supply very fine powder using ultrasonic vibration. It has been well known that very fine powder inside a hopper forms easily powder-bridge. This behavior prevents the powder from continuously flowing. The author, however, utilizes the behavior in this study. Namely, the powder on a plate with multiholes of a suitable diameter can not flow out through the holes because of the powder-bridge, when the plate is not vibrating. On the other hand, the powder can flow out continuously, when the plate begins vibrating. The flow rate can be easily controlled by holding vibrational velocity of the plate at a fixed level. The paper deals with fundamental studies for this kind of powder supply.
