Abstract: A circulation-air generating unit directly generates circulation air that flows along a surface of a cleaning tank. The circulation air is applied to cleaning medium accumulated on the cleaning tank from a direction orthogonal to a direction of face of the cleaning medium to deliver and flow up the cleaning medium. The cleaning medium is flown up inside the cleaning tank by the force of the circulation air. The cleaning medium flowing inside the cleaning tank collides with a cleaning target object by high-velocity air supplied from a cleaning-medium accelerating unit to remove dust on the cleaning target object.

Abstract: An apparatus maintaining adjusted positions of parts assembled by adhering includes a device coating plural sections between a part and an adhering target with light energy curable adhesives adhering the part to the adhering target, a light energy irradiating device for curing the adhesive, and a detecting device detecting a displacement of the part from the adhering target. A curing shrinkage force control device is also provided to control the light energy irradiating device to change the light and thus control curing shrinkage forces to offset undesirable stresses generated by the curing shrinkage forces when undesirable displacement is detected.
