A surface acoustic wave actuator is disclosed which includes unidirectional interdigital transducers disposed on both sides of a vibrator and an electrical combiner. One of the unidirectional interdigital transducers and external power supply are connected to an input port, and the other unidirectional interdigital transducer is connected to an output port of the electrical combiner. The electrical combiner combines input energy from an external power supply and surface acoustic wave energy is electrically converted by one of the unidirectional interdigital transducers, and input to the other unidirectional interdigital transducer. Surface acoustic waves excited by the other unidirectional interdigital transducer propagates on a vibrator, and is input to the other unidirectional interdigital transducer again after passing one unidirectional interdigital transducer and the electrical combiner. A relative movement member is pressed against the vibrator for generating driving force via a friction force so that the relative movement member implements relative movement to the vibrator.

A liquid coating nozzle is provided with a first block which has an inner liquid reserving section that extends in the longitudinal direction and an inner discharge section which includes a plurality of small holes formed in the longitudinal direction at a bottom portion of the liquid reserving section. The nozzle is also provided with a second block which has an inner space defining a gas reserving section that extends in the longitudinal direction outside the first block and an outer discharge section formed in the longitudinal direction at a bottom portion of the inner space. The outer discharge section includes a plurality of small holes and produces a gas flow that externally surrounds a linear or curtain-shaped liquid flow that flows downward from the small holes. This results in the formation of a thin coating film in a short time and reduces the consumption of liquid and coating nonuniformities.
