Seating of composite inlays with ultrasonic vibration
Dental Update, 1999The use of vibration enables the clinician to use high-viscosity luting agents when seating composite inlays and allows quick and efficient placement of the inlay. The film of composite luting agent is achieved in a much shorter time and with lower loads by ultrasonic vibration than using manual methods. In order to achieve a thin lute, the vibrations

Influence of ultrasonic vibration on micro-extrusion
Ultrasonics, 2011Micro-forming is a miniaturization technology with great potential for high productivity. Some technical challenges, however, need to be addressed before micro-forming becomes a commercially viable manufacturing process. These challenges include severe tribological conditions, difficulty in achieving desired tolerances, and short tool-life due to ...

A vibrators alternation stepping ultrasonic motor
Ultrasonics, 2006A new concept of a vibrators alternation stepping ultrasonic motor, based on longitudinal vibrations of rectangular Langevin resonators, is presented. The new motor fed by a single-phase resource without feedback is capable of bi-directions step displacements without accumulative displacement error.

Solubilization of Erythrocyte Acetylcholinesterase by Ultrasonic Vibration
Nature, 1967ERYTHROCYTE acetylcholinesterase (AChE) is strongly bound to the cell membrane1. To isolate and purify this enzyme, it must be removed from the membrane and brought into solution. Methods used for this purpose have included treatment with butanol2, digestion with pancreatin3, or addition of a surface-active material4,5. More recently, we have succeeded

Method of oscillating ultrasonic vibrator for ultrasonic cleaning
The Journal of the Acoustical Society of America, 1996An ultrasonic vibrator has a single natural frequency for radiating ultrasonic energy into a cleaning solution to clean and deburr workpieces that are immersed in the cleaning solution. A plurality of oscillating signals having respective different frequencies which are integral multiples of the natural frequency of the ultrasonic vibrator are ...

Ultrasonic motors with polymer-based vibrators
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2015With their characteristics of low density and elastic moduli, polymers are promising materials for making ultrasonic motors (USMs) with high energy density. Although it has been believed for a long time that polymers are too lossy to be applied to high-amplitude vibrators, there are several new polymers that exhibit excellent vibration characteristics.

The effect of ultrasonic vibration on the compaction characteristics of paracetamol
Journal of Pharmaceutical Sciences, 2000An ultrasonic (US) compaction rig has been developed that is capable of providing compaction pressure together with high-power ultrasonic vibrations of 20 kHz to a powder or granular material in a die. The rig has been used to investigate the effect of US on the compaction properties of paracetamol, a drug that produces tablets that are weak and ...
