Abstract: A high-efficient oscillatory circuit drives a piezoelectric crystal (transducer) which is coupled to an ultrasonic cleaning tank. The circuit includes a transistor switching means in the driver side of the oscillator. The primary winding of the transformer is coupled in parallel with a capacitor and forms a circuit having a resonant frequency which is a multiple even integer of the resonant frequency of the crystal which is coupled to the transformer secondary winding.

Abstract: A method of fabricating a film vibration device, including: photoetching a surface of a silicon wafer to form a circular-hole array; etching an aluminum layer on the silicon wafer; etching the silicon wafer to form a through-hole array to obtain a porous silicon wafer; attaching a polyethylene terephthalate (PET) sheet to a side of the porous silicon wafer; ablating the PET sheet to obtain a porous PET film; attaching a polyvinylidene fluoride (PVDF) film to a lower side of the porous silicon wafer; performing vacuumization above the porous silicon wafer, while heating the PVDF film below the porous silicon wafer to create dome micro-structures on the PVDF film; and laminating the porous PET film on each of two sides of the PVDF film to obtain the film vibration device. This application also provides a cleaning device having the film vibration device.

Abstract: Methods and apparatus for cleaning brushes quickly, comfortably and efficiently are disclosed. The apparatus contains at least one cleaning chamber comprising a plurality of cleaning elements disposed within the chamber that contacts the brushes during cleaning, the cleaning chamber in contact with a) a drive and a motor that can deliver rapid reciprocating motions to the cleaning elements, b) a solvent flow system, and c) a removable brush holder connected to a motor that turns the brushes slowly over the cleaning elements. Rapid reciprocating motions of the cleaning elements, continuous flow of a solvent over the brushes to be cleaned and a slow rotation of the brush itself over the cleaning elements achieve rapid cleaning of brushes with little damage to the brush itself. A removable brush holder that can accommodate many different kinds of brushes in the same slot extends the functionality and comfort of using the brush cleaner.

Abstract: Acoustophoretic devices for separating particles from a non-flowing host fluid are disclosed. The devices include a substantially acoustically transparent container and a separation unit, with the container being placed within the separation unit. An ultrasonic transducer in the separation unit creates a planar or multi-dimensional acoustic standing wave within the container, trapping particles disposed within the non-flowing fluid and causing them to coalesce or agglomerate, then separate due to buoyancy or gravity forces.

Abstract: In a deburring device configured to remove burrs of the molded product through radiation of ultrasonic waves, a height of the storage tank is set to 1.25λ mm when a wavelength of an ultrasonic wave is set to λ mm. A frequency range of ultrasonic wave radiating means arranged on a bottom side of the washing water storage tank is set to from 18 KHz to 28 KHz, and power density is set to 2 W/cm2 or higher. Further, there is arranged oscillating means configured to allow the molded product immersed in the washing water to vertically move with a stroke of at least 1/2λ mm in a vertical direction. Further, an amount of dissolved oxygen in the washing water is set to 1 mg/litter or less, and a water temperature of the deburring washing water is set to from 4° C. to 8° C.
